The Best Under-Counter Water Filter (Review)

The Best under-counter water filter

Our family has had a Berkey water filter for years and we absolutely love it. Before that, we had a basic reverse osmosis water filter, and while I loved that it was getting rid of all fluoride in the water, I never loved the taste or that we had to add minerals to the water to avoid nutrient deficiencies since reverse osmosis removes all minerals from water.

The Berkey with the added fluoride filters was doing the job really well, but I got many questions from readers wanting an under-counter easier option so I decided to research to see if there were any better options. To be clear, we still love the Berkey and I think it is a great all-around water filter.

Why a Water Filter?

As I explained before:

If you are drinking tap water, the answer to that question is 300+ chemicals and pollutants, according to research from the Environmental Working Group. Among these contaminants are:

  • Arsenic—This odorless and tasteless semi-metal element enters drinking water supplies from natural deposits, as well as agricultural and industrial wastes. Human exposure to arsenic can cause both short and long term health effects, including cancer
  • Bacteria—Nasty pathogens from human waste and soil runoff frequently contaminate well and city water, posing a risk for serious illness upon exposure. City water is commonly derived from treated sewage.
  • Chlorine—This free radical disinfectant can quickly damage our hair, skin, and lungs when we bathe or shower. It has also been shown to cause gastric upset upon ingestion and has been linked to malfunction of the liver and immune system with long-term exposure.
  • Chloramines—Now being added to nearly all municipal water districts, they are formed by the combination of chlorine and ammonia. Chloramines are so strong that they tend to dissolve the inside of your pipes and fixtures, releasing contaminants and heavy metals into the water. Chloramines have been linked to anemia, liver, kidney and central nervous system problems, as well as reproduction effects.
  • Fluoride—Many communities receive pretreated, fluoridated water to their homes. Fluoride, known as “The Devils Poison”, has been shown to be less than effective in preventing tooth decay, while possibly contributing to a whole host of health concerns.
  • Gasoline—Easily absorbed into the soil, even a small gas spill or leakage can contaminate ground water sources. Considered a hazardous waste material, consumption has significant adverse effects on the central nervous system.
  • Hardness— Hard water is the result of calcium and magnesium present in the water. These minerals form white scale buildup creating problems for water heaters, washing machines, dishwashers, and plumbing systems. This condition creates a lack of lather when using soap and can contribute to dingy laundry.
  • Hydrogen Sulfide and Sulfates—Hydrogen sulfide and sulfates occur naturally in rocks and soil and can result from organic material or occur when wells are drilled in shale or sandstone. Although not a significant health risk, these elements can be nuisance. Hydrogen sulfide gives off a rotten egg small and taste and can produce stains on appliances and fixtures. Sulfate can cause water to taste bitter and scale to build up in pipes causing damage to plumbing and appliances.
  • Iron—Iron in water will present red staining on tubs, sinks, showers, faucet fixtures and laundry
  • Iron Bacteria—Iron bacteria can be introduced to well water during drilling, repair or service. If there is a musty, moldy or swampy odor associated with well water, an iron bacteria analysis should be conducted. While iron bacteria does not pose a health risk to humans, it can damage a well system and dramatically impact water quality.
  • Manganese—If you experience problems with brown or black staining of your laundry, this may be due to high concentrations of manganese
  • Nitrates—These hazardous chemicals come from fertilizer runoff, leaking septic tanks, sewage and erosion of natural deposits. Nitrates are converted to nitrites in the body. High levels of nitrites have been shown to be deadly to infants under the age of 6 months, and to cause serious health risks in others.
  • Pesticides and Herbicides—Ground water is often polluted by poorly managed fertilizers, insecticides, herbicides and pesticides. These poisons can easily seep into well water aquifers and municipal water reserves. Exposure has been linked to chronic illness, birth defects and immune system failure.
  • Radon—Radon is a high risk radioactive gas found in drinking water and indoor air. Exposure to radon in drinking water increases cancer risk, particularly lung cancer.

Under-Counter Water Filter

Again, we love our Berkey, but I had gotten so many questions about under-counter water filters that I wanted to find the best option to recommend to readers (and family). I wanted an option that would:

  • Remove fluoride, chlorine, chloramine and other contaminants with at least 99% effectiveness
  • Did not strip all minerals from the water or that added them back in
  • Was not astronomically expensive and that did not require replacing filters too often
  • That provided water for our whole family at a low daily cost (under $0.50 per day for our whole family)

I found many filters that did parts of this but had trouble finding any that did all of it. One day, while shopping at my go-to real-food store online (Radiant Life Catalog) I clicked on their 14-Stage Water Filter just on a whim and started reading.

Imagine my surprise (and how dumb I felt) when I found that one of my favorite companies already made a water filter that met all of my specifications and more. I actually got the chance to talk to their main water expert and I quizzed him incessantly about how the filter worked, the percentage of contaminants it removed and filter life, and was even more impressed.

RO + Minerals + Carbon + UV + More

The Radiant Life Under-Counter 14-Stage filter is the only water filter of its kind and the only one that filters and remineralizes so completely. With this filter, water goes through all of these stages:

Stage 1 – Five Micron Pre-Filter
Stage 2 – Internal Coconut Shell Carbon Filter
Stage 3 – Reverse Osmosis Membrane (Purifier #1)
Stage 4 – Mixed Bed De-Ionization Purifier (Purifier #2)
Stage 5 – Mixed Bed De-Ionization Purifier (Purifier #3)
Stages 6 & 7 – Homeopathic Restructuring – Erasing Memory, Molecule Coherence
Stage 8 – Holding Tank – standard tank holds about 3 gallons of pure water. Other tanks are available.
Stage 9 – Ultraviolet Light – 14 Watt
Stage 10 – Reprogramming – Adding Natural Mineral Properties
Stages 11-12 – Far-Infrared Reprogramming
Stage 13 – Coconut Shell Carbon Post-Filtration
Stage 14 – Alka-Min (Alkalizing, Ionic Remineralization)

It removes fluoride, lead, chlorine, MTBE, chromium-6, nitrates, pesticides, pharmaceutical residues, water-borne illness and more.

Is this a normal Reverse Osmosis system?

I wondered what separated the RL system from other reverse osmosis systems on the market. Most of them remove fluoride, chlorine, etc at high rates, but the Radiant Life System is unique:

There are several key things that make the 14-Stage system unique. First, it incorporates three purifiers (reverse osmosis and two deionization purifying stages) to form the foundation of the system, which ensures 99.999% purification when new, only falling to 99.9% over time. Almost all other reverse osmosis-based systems use just one purifier and thus may start at 95% purification, but after a year that figure will often be as low as 80%. This is just one of the things that water dealers won’t tell you.

The unique pre- and post-filters offer additional filtration (two of these filters are unique in the industry) and also include a stainless steel and quartz UV light for added protection against bacteria and pathogens. These first seven stages are designed to remove all toxins in your water, no matter if you even know what they are!

The reason that we had initially moved away from a Reverse Osmosis filter is that while it removed almost all contaminants, it also removed many minerals and there was some evidence that drinking demineralized water could actually cause problems for the body long term.

The RL system removed this problem as well by adding minerals back into the water in the proportions that the body needed and even going so far as to add post-filtering infrared programming to essentially make the water “alive” again.

Where to Get?

Radiant Life is the only place I’ve ever found that offered this comprehensive of a water filter. We recently installed their 14-stage filter under our kitchen sink, and I’ve loved the convenience of it. Again, I still think the Berkey is a great option, but I wanted to test an under-the-counter option for readers who had asked and I couldn’t be more pleased.

It took about an hour to install and now we have clean water on-demand from a spigot at our sink. My only complaint with the Berkey was the constant hassle of refilling, and our 14-stage filter removes that hassle.

The new filter was a big jump for us and something that we saved for and considered for a long time. We actually also got the whole-house filter for shower water since I am so sensitive to fluoride and chlorine in shower water with my thyroid condition and I’ll be sharing about our experience with this soon.

Unfortunately, good water filters are an up-front investment but the daily cost is $0.30-$0.40 a day, which is definitely manageable over time. The RL filter also has a built-in water testing kit so that you only replace the filters when needed, saving additional time and money.

The Best Option?

Like I said, Berkey is a cheaper option and I think it is still a great filter, but if you are looking for the next step up or want an under-counter option that won’t take up counter space, the 14-stage filter is my new go-to favorite by far!

I love that Radiant Life is a family owned-company and I’ve had the chance to visit with the family who owns it at several conferences. The Radiant Life family cares so deeply about real food and natural living, and they are all very knowledgeable about water, air and food quality. They are also just genuinely good people who care about the future of our children, and the environment.

Though the 14-stage filter wasn’t inexpensive, I feel like it is a great deal for what it does and I love that we supported a family-owned US based company.

If you’re still trying to decide what the best water filter is for your family, they offer consultations with their team of water experts and can help guide you to the best option for your family.

I’d love to know…what water filter do you use? What do you want in a water filter?

  1. thanks so much, Katie! I just read your post on Facebook!
    What a great article!
    We have hard water so have installed a whole house filter. It is an Aqua Pure Waterconditioning system.
    “It removes rust, sediments, and the taste & odor of chlorine from drinking water.”

    What are your thoughts?

    • Those are good too, in fact, we’ve installed a similar one and I’ll be reviewing it soon too, but from what I researched, an additional one for drinking water is helpful for ensuring the proper mineral ratio

      • I have been drinking distilled water for at least 20 years. Distillers seem to last a lifetime and require no fancy filters. My reason to post is that in all this time, I have never had an imbalance in minerals or electrolytes. Every year I ask my doctor to check that when doing my annual bloodwork. Always perfect. I eat well, organically when possible, and enjoy life. I do not take vitamins or minerals. Maybe living a joyful life, grateful for all there is, is the best prescription. I am 60.

        • Where does one find a water distiller? Brand name of the one you use? Thanks.

          • I have watched a few videos by Glenn Meder. He does an excellent presentation on his water distiller. I don’t have the link anymore but if you google him you will find him. HTH

    • Great article, Katie, how about negotiating a discount for your readers????

      • How would you rate the Amway eSpring system?

        • That’s what I’ve used for the last 10 years. I love it but would love to know how it compares to the other ones out there.
          We drink a LOT of water, and we always crave our espring water when we get home!!

  2. This article was so timely for me as I’ve been going through the grueling process of finding the right system for our home! I’m curious about the reverse osmosis type of system because I keep reading that it is a huge waste of water. Is this true do you think? This system looks amazing!

  3. if you went with their whole house system wouldn’t the under sink option be unnecessary?

  4. Years ago we were in Amway & believe it or not, that’s where our healthy living began. They had the most awesome whole food vitamins & suppliments, they sparked my interest to learn all i could about what vitamins do for our bodies & their water filters were top of the line! Loved ours, everything to follow is compared to it. It would be worth doing some research on them if your looking.

  5. we love our aquasana filter! I’m happy with the quality and the taste is excellent!

  6. Hi Katie,

    Right now I am still living in an apartment (hopefully that changes in the coming year!) so the under counter filter isn’t an option for me. However, I have been seriously considering purchasing a Berkey countertop filter. I was wondering what size Berkey do you have for your family? I have a family of four so I am not sure what size will be right for us. Thanks so much!

    • We have the Crown, the largest one, but my parents have the middle one and it works great for 2-4 people

  7. Berkey all the way!! We’ve had ours for about 8 years and only had to replace the filters just recently. My husband is our own personal water tester – he can tell when the filters need to be scrubbed because he will be getting up at night to pee…strange but accurate!

    We have mountain spring fed well water that is delicious, but it is high in iron and we do have to think about bacteria and parasites. The Berkey has worked so well for us. No need to change. Filling it is fun for the whole family! 😉

    • Lauren,
      We have a new Berkey and love it! But how often do you ‘scrub’ those filters-approximately? And how? It seems monumental to take it apart! I also heard I am supposed to take the spigot apart every 30 days and disinfect. Is that necessary? I know these tanks must need cleaning sometime!

    • I love my Berkey. Hard to imagine anything coming close. I have a closet size studio kitchen and have to keep mine in the room outside the kitchen. As much as I would love an under the sink set up I am not willing to give up this quality and simplicity. I have come to love tending to the Berkey. I love how this serves as a reminder of how precious is pure drinking water and the importance of protecting and improving our natural watershed areas.

  8. Years ago, I used to participate Amway business for a few years and that was how I purchased water treatment system. A few years ago, it was time for me to replace one so I purchased through Amway again and have used it ever since. It is Amway eSpring UV Water Purifier system that includes electric module that shows you how soon it is time to replace cartridge which means you need to have a plug under the sink if located under the counter or on the counter. At first, I was upset with huge expense on an electrician and a plumber for a plug under the sink. I recently moved to a rental apartment so I don’t install a plug under the counter anymore but put the water purifier system on the counter at the back of the sink. I replace water purifier replacement cartridge every once a year. I am pretty satisfied with it.

  9. I need a filter that takes out extremely high levels of manganese. Would this work?

  10. So this one results in alkalized water, correct?

    That is debatable for consumption, right?

    • It isn’t alkalized water in the sense that you hear it from companies with pitchers and devices that supposedly change the structure of the water, it just has the minerals added back in, making it slightly more alkaline that acidic.

  11. Just wondering: I have a well, a rather shallow well; can I install this at the well and have a whole house filter? I am not worried too much, but would like to find a system that I can easily install (hence at my pump house, rather than under a sink, where there really is no room!) I have only one bathroom and a kitchen, but there is NO storage at all, so having it in the house really won’t work for me, why I would like to install at the well…..
    Thank you for this article…

  12. I have used one from Pure Earth for about 4 years and just love it! We test our water regularly and it removes a ton of junk whilst saving us from having to make holes in our countertop or take up lots of space.

    • Hi, Jessica

      Just wondering how do you test your water, especially fluoride? Thanks.

  13. Another great post.

    We’re planning on getting the Big Berkey when they are back in stock. However, we’re going to look into this under-the-sink system and save up for it for perhaps next Christmas.

    Besides the benefit of getting a great water filtration system, it’s great to know we would be supporting a U.S. company/family too.

  14. What are the maintenance requirements of the RL system? Does it require weekly cleaning? How often do you change filters? Thank you so much for this review!

    • There is no weekly maintenance. Filters only need to be changed every two years (or often much more). It mounts under the counter so it is really easy to use.

  15. As someone else mentioned, your article was timely as we’ve been discussing finding an under-the-counter water filter system. This sounds like a winner that we’ll be budgeting to purchase.

    Also thank you for the silicone article, another question I’ve had for some time.

    By the way, I’m a grandma with grandchildren taller than I am and I’m learning plenty from your newsletter. Thank you!

  16. will you send a sample of the water out to be tested to make sure that the fluoride is really gone? and let us know of the results Ive heard that its not expensive to have water tested. if it works I will defintly buy one.

  17. Hi Katie, Just wondering if you receive any form of compensation from Berkey or Radiant?

    • Hi Ann- thanks for asking. My affiliate policy is at the top of each post, but I am an affiliate for several companies, including those two. I only become an affiliate for a company or product after buying the product myself and trying it objectively. The cost is the same for you, and the small commission I make if anyone purchases through my link helps pay the blogging bills. 🙂

  18. I have been using the Life Ionizer brand water filter for about 2 years now. It is supposed to be comparable with the Kangen water filter. It looks like is has some of the features your new water filter has including UV Light and alkalizing and acidifying options. So far I like it and the options of being able to choose the pH of the water I use is helpful. The customer service on the other hand is not very good and it is not international- friendly… and if I knew that would be the case, I probably would have bought a water filter somewhere else. Here’s the one I got if someone is interested.

    Just curious Katie, since your new machine can control pH levels … do you clean your produce by using acidic or alkaline pH water? Or use them for others tasks around the house? I find this to be very helpful for me and I use a high alkaline setting to soak my veggies to clean them.

  19. hello,

    We’re redoing our house top to bottom and are in the market for a water purification system. We have extremely hard water in our town. I love everything that this system offers but how does it work for both showers and drinking water? Are they two separate products? Has it helped for showering (i hate showering it dries me out so much it hurts)

    • Yes! I’ll be reviewing their whole-house system soon but it dos work for showers and drinking water and it is amazing!

      • Katie, do you have a chart that compares pros and cons of multiple systems?

      • Hi katie, have you had the chance to review a whole house water purification system?

          • Would love to read that review if it has been posted. We are building a house and I’m suppose to be buying a whole house filtration system (we are on a well) this week! Please let me know if you’ve posted your review yet. Thanks!!!

          • Unfortunately I just invested in a standard RO system… It does remove all minerals. Wish I had found this sooner! What would you recommend using mineral wise to add back to the water? I’m reading standard RO can cause all kinds of health issues and would love your thoughts on this. They specifically mention health conditions for unborn babies and infants (I installed bc I was pregnant!) thanks!

  20. Thank you for this post. I am currently looking for water filters. These are out of our budget, but I would love to know if anyone has any insight on the aquasana Rhino whole house and the Crystal Quest refrigerator in line 7 stage filter with fluoride filtration. We are building a new house, and I am planning to get both of those, but I would love real person reviews :). Thanks!

  21. There are many systems which do what the RF filter does… The difference that RF pays more in affiliate marketing fees to this site, that is why you see this article, which is basically an advertisement for RF. Don’t waste $1600, the other RO systems with a remineralisation filter costs $400 or less…

    • Wow- cynical much? That actually isn’t true at all. I could make much higher affiliate commissions from other companies and I support Radiant Life because I’ve tried many of their products (which I purchased, btw) and found them to be the highest quality. They are also a family-owned company. Their 14-stage filter is the only one in the industry like it and in my experience, it works incredibly well.

  22. We’re on town water that has won awards for the amount of flouride it puts in the water (!) so we’ve been looking for an affordable under the sink system to filter this out. As I look through RO systems it seems like they all have a lot of plastic (tubing, filters, storage tank linings, etc).
    Are the contaminants from the plastic tubes worth the filtration benefits?

    • Unfortunately, I’ve never found a filter without any plastic. It is frustrating, but I consider the potential problems from this food grade plastic less than the potential dangers of water contamination.

  23. I love radiant life and have learned a lot from them. However, when I researched their system ans spoke with someone at radiant life I found out their water filter changes the PH of the water slightly. I spoke with Dr Thomas Cowan (the Fourfold Path to Healing), whom I trust. He recommended, especially for children, to not drink water regularly with the changed PH. After extensive research on my own and then coming across your articles, Katie, we have a Berkey filter and are very happy. I just wanted to pass on what I learned, I am sure everyone will find their right filter.

    • Does the berkey remove fluoride?

  24. This is so horrifying! I want to look into getting a filter for my family.. What does a typical water filter (on the sink or from the fridge) actually filter out, if anything?

    Thanks for all of this information!


    • It typically filters chlorine (to some degree) and various other contaminants but not completely.

  25. Hello I was just wondering what you thought about Propur filters? I originally was a toss up between proper and big Berkeley, what are your thoughts on this company? Also how would an average person go about getting their filtered water tested to compare on their own?

  26. I researched water filters for quite some time before buying one. I finally settled on the Vivec RO system. It does remove the minerals or some of them so I talked to my ND first. This specific system works with ceramic beads and reintroduces minerals back into the water. So far happy with it. The newer units are updated to show when you need to replace the cartridge.

  27. I just replaced my water filter system as well. One thing you may also want to consider when you purchase a filter is whether is also removes pharmaceuticals which are increasingly present in the water and if it alkalinizes the water as well.

  28. I purchased the Miracule water filtration system about 5 months ago. “It’s the only water filtration system in the world with a patented ORME trap! The MiraculeWater processors have a patented trap on the inside to retain all of the minerals and monoatomic elements while removing all of the harmful contaminents. The result is an alkaline water with the beneficial minerals intact.” I selected the counter-top version after being assured I could later purchase a transition kit to place it under the sink. (I don’t have a any plumbing skills and no one in my life to help me.) I’ve been very happy with it. If I accidentally swallow water while brushing my teeth in the bathroom, I can immediately taste the difference! I think the price was quite reasonable. Filter replacement is recommended at 6 months, which is coming up quickly. I hope it’s not a major project. I would like to get a whole-house water filtration system, but have yet to start comparison shopping. I look forward to your article on that subject.

  29. Hi
    Does anyone have any experience in the clearly filtered water pitcher, which is apparently BPA free, and meant to remove floride, seems fairly reasonable also?


  30. All I know from my research is that flouride is very hard to remove. It can only be removed using a Reverse Osmosis system.

  31. Hi!

    I do not know about the specific water pitcher you mentioned but I would caution against all plastic. Manufacturers have had to replace BPA with other chemicals. I read that the replacements (BPS and other chemicals) are just as toxic (one article says even more toxic and more easily absorbed). You can find plenty of articles on the subject so please, do not take my word for it.

  32. This sounds good, but I don’t see any mention of the ratio of purified water to waste water, which is the primary drawback of RO in my opinion, especially in drought ridden CA.

  33. We currently have a RO system in our home. Do you recommend any certain brand of minerals to add back in? Thank you!

    • I purchased a RO unit from Vitev a few years ago.

      I got their latest Ultra Water Filter. I bought it since it puts back minerals into the water using their ceramic beads. I didn’t know any other system that had this technology at the time.

      I had to replace the filters and found out that the Ultra was discontinued. They had replaced the Ultra with the MAXX. So I ordered it and it’s coming tomorrow.

      This turned out to be a good deal for me since they only charged me what I would have paid for the new replacement cartridges for the Ultra. The rest of the equipment is interchangable. Their warranty is five years.

      I just wish there was a built in alert to tell you when to replace the cartridges instead of having to count the gallons every day.

      I also found out that you have to flush out RO systems each month, sounds like it’s the same way you flush out your water heater, so will have to get info on that too.

  34. I really like the idea of the Radiant Life system too-But my husband and I can’t justify the water waste especially with the major drought we are experiencing. I wish RL would come up with a ‘zero waste’ attachment like some other RO systems have done. Still waiting for the ‘perfect’ solution to our water situation!

  35. Hello,

    I’m wondering what your thoughts are on the fact that the Radiant Life Purification system is made of plastic vs. the stainless steel components of the Berkey. I was also wondering if you have looked into these filters at all:

    I am trying to find the best possible water filtration solution for making my daughter’s infant formula.



    • The RL system has some plastic but it is BPA free and the fluoride filters on the berkey were plastic as well. We still love the Berkey and travel with it, so it is a great option, but after researching a lot, I found that the under counter one removes more from the water. We actually had an under counter system similar to the one you linked to in our first home, but had some trouble with it leaking (probably just a fluke with ours) and I got tired of changing the filters, but it also filtered the water well.

  36. Hi Kelly. So do you need to buy a separate Radiant Life product to filter your whole house or can the 14 stage filtration be used for the whole house & drinking water too? If yes, can you please include a link for their whole house filter? Also, can this 14 stage system be hooked up to my fridge so I can get filtered water & ice? Thanks!

    • Katie, love your site!! Such a great resource! I wanted to see your thoughts… I have a well and we needed a whole house water softener. Now we are having a hard time deciding what to do… we bought the Berkey but think we will return it bc of our water softener and that it may be a pain filling and cleaning the filter each day. So the RO systems seem interesting and we definitely cannot afford the RL. Here is one we can afford but worry about minerals being lost.

      Any advice would be great!

  37. Katie, I’m researching under the counter water filters including the Radiant Life 14-stage filter that you recommend. I have a concern about the filtered water produced by this filter being at a ph of 8-9 as Tom at Radiant life told me today. Below is an excerpt from an article by Dr. Mercola:

    “As is true with many things, in the end it’s a matter of balance. Water that is too acidic or too alkaline can be detrimental to human health and lead to nutritional disequilibrium. This was demonstrated in a Swedish well water study, 15 which found both pH extremes to be problematic. Your body simply was not designed to drink highly alkaline water all the time. So I believe it’s best to be VERY careful when it comes to something as foundational as the water you drink on a daily basis. If you get it wrong, you could really cause yourself some major damage. It makes sense that you are designed to drink water that occurs naturally, which excludes alkaline water with pH levels of 8 and above.
    And if you drink alkaline water all the time, you’re going to raise the alkalinity of your stomach, which will buffer your stomach’s acidity and impair your ability to digest food, as low stomach acid is one of the most common causes of ulcers. This can open the door for parasites in your small intestine, and your protein digestion may suffer. It also means you’ll get less minerals and nutrients over time – in fact, some of these health effects can already be seen in hardcore alkaline water drinkers. Alkalinity is also potentially a problem because it is antibacterial, so it could potentially disrupt the balance of your body’s beneficial bacteria.”

    I was wondering if you could address the issue of filtered water being on the alkaline side. Thanks.

      • Any updates ma’am? I’m desperate for an under the sink water filter but this alkalinity issue makes me nervous! Researching water filters makes me feel ill 😛 THANK YOU!!

        • Yes! Post was a lot to research, but in short, I dont worry about the alkalinity of this water and I do add lemon or vinegar a couple times a day to get the pH down.

    • I’m also interested in any info you have found.

  38. Is there a shower filter anyone would recommend? We are not ready to do a whole house filter and would like to at least address the water we shower with and the kitchen drinking water which I realize would be a different filter but this blog has given many different brands to look into but there was no mention of a separate one for the shower. Thanks.

  39. I did my research on shower filters and finally bought Aquasana.

    They take out 98% or 99% of chlorine and most other contaminents.

    You can buy them directly from their website or from Amazon which is more money.

    If you buy from their website and sign up for automatic deliveries, you get a discount on the filter and shipping is free. It takes ten days after they ship it out. HTH.

  40. What are your thoughts on Aquasana? They are made in America and seem to be pretty good, aside from not removing fluoride. When we move, I plan to look into the one in this post. But I’m curious of your thoughts, on aquasna, if you have any. Thanks!

  41. Hi Katie,
    I am thinking of buying the Radiant Life 14 Stage filter. Are you still happy with it?

      • Hi Katie, Thanks for this post! I don’t know if you mentioned it anywhere, but it would be helpful for those who can’t afford any water purification to know that by just adding Vit. C, you can remove chlorine from water. To give an idea of how much Vit. C is needed: One 1000mg Vit.C capsule’s worth is enough to remove the chlorine from a bathtub’s amount of water, so just a smidgen is needed for a pitcher. 🙂

  42. I read above that you were working on a whole house system review. I can’t find it can yqou direct me to it?

  43. Hi Katie, how do you compare the 14 stage water filtration with the berkey? I want a whole house filter and already have a berkey. We cannot afford to have the whole house plus the 14 stage filter, so I come to the conclusion of buying the whole house filter and keep saving to buy the 14 stage latter meanwhile keep using the berkey for drinking and cooking. Before I do this, I need help if you could. Thank you Katie for you time. Blessings!!!

  44. We have a berkey and want to buy the whole house filter. We cannot afford to have the 14 stage, so I am thinking of buying the whole house and keep saving for the kitchen filter and meanwhile use the berkey for drinking and cooking. I will appreciate any advice.

  45. Anyone know of a shower filter that removes fluoride? Also we are renting a house right now so does anyone know of a system that could filter the water of the whole house without having to take appliances apart? thanks 🙂

  46. Have any of these reduction claims been tested by a third party lab? Or certified by any organization other than the people that make these? These are some hefty promises that people want to hear, I hope it passes health and safety standards for drinking water treatment units.

    • This is what I am wondering too. I’ve sent an email to RL & Berkey.

      • Can you share their response?

      • I’m interested in a high-quality water purification system but can’t seem to find any factual analyses of this Radiant Life system. How does it really compare to these iSpring systems, for instance, at removing chemicals and particulates? Is there third-party verification of the RL system? How do I know that buying this filter actually means I’ll be getting cleaner water than the following systems? I am on municipal water so it’s already filtered, softened, and chlorinated/fluoridated. I’ve done hours of reading today and I can’t find any significant difference between these systems (which are also multi-filter and RO, with alkaline remineralization added back in) and the RL system, except the drastic difference in price. The FAQ on the RL site is not very specific and only lists general “we’re better than those other systems!” claims. This isn’t helpful.

  47. Best filter if you are rich lol I mean who pays $1500+ for a water filter? Absurd and outrageous

  48. I would love to have a system that removes fluoride and other nasties. Unfortunately, my budget only covers a Brita Pitcher.

    • I got an AlkaViva elita CT-700 for about $300. It removes fluoride and pharmaceuticals. It is cheaper than most because it is above counter and it is not electric – works on water pressure. The replacement filters are a little over $100 and last for 700 gallons. The only problem I have had with it is the display that counts down how much water- it doesn’t work anymore. I think it got wet one too many times and that was that.

  49. I have been searching for an affordable way to filter the water for my birthing tub without much luck. Please if you have any advice on that it would greatly appreciated.

  50. Has you or any of your followers used the Natural Action Technologies water filters. I have had a friend who uses the portable one at home for all of her drinkable and cooking needs. She and her husband have said their animals if given a choice between tap water and the water gone through the system. The animals will not touch tap water. We live in small community, but our water is treated with chlorine. I don’t like the smell of swimming pool when you shower or wash dishes. This is a filter you do not have to replace. Although expensive to start seems very affordable with that fact and ease installation. Please if anyone or yourself have looked into to this. Please comment! Thank you Geretta

  51. How many gallons of water does the Radiant Life filter waste for every gallon of treated water produced?

    I’ve seen other RO systems claim to waste 3 to 5 gallons of for every gallon of clean water produced under ideal conditions. Actual waste will vary with pressure and temperature. I measured my parent’s RO filter water waste rate by placing the drain hose into a bucket. It was over 10 gallons wasted per gallon of clean water produced (3x what the manufacturer’s estimate).

    • That’s obscene! I would also like to know. Their site also doesn’t state GPD or GPM, just tank capacity. Is it super slow to refill?

    • It wastes “about” 2.5 gallons for every gallon of clean water produced according to the FAQ section on the manufacterure’s product webpage. A waste ratio of 2.5:1 (wasted water to clean water produced) is lower than most systems, however, I’ll believe it when I see it. It would not surprise me at all if actual results are more like 5:1 or higher, as other systems can be way off.

      Water inlet pressure and water temperature will cause the waste ratio to vary. Higher pressure = lower waster. The only RO systems I’ve seen with lower advertised waste ratios are the iSpring with pump (2:1 waste ratio) and the iSpring commercial tankless (1:1 waste ratio). The iSpring with a pump increases the pressure which increases the efficiency of the system.

  52. Hi Katie,

    Your post is very interesting. I have just started researching purification filtration systems for my home; I will be very interested in your upcoming post about the Radiant Life filtration system for the whole house. I understand there will be an investment, but I can’t imagine a better investment than getting clean water in my home. I have been purchasing 21/2 gal. glass containers of distilled water from Mountain Valley, but it is very expensive, and i would like to be able to cook with the filtered water and also shower in it. Please give me any advise you might have.


  53. We have an Alexa Pure water filter system that my mother in law purchased it. We weren’t sure about it working because it failed a TDS test. Is this normal and does this filter seem to be the same as a Berkey system?

  54. Just wanted to let you know our experience with the company Radiant Life…

    Overall I would never recommend this company or their products to anyone. More than anything was the way they treat their customers, their products are so-so, but customer service is terrible. I hope they below helps prevent someone from making the same mistake our family made.
    · Nice looking website, easy to navigate and order

    · Instillation is not included, it’s up to you as the consumer to find and pay

    · No field technical service and they won’t send anyone out for evaluation nor do they contract with any local companies to physically evaluate the system if anything is wrong. The only option is to call their 1-800 number or send an e-mail and wait for a response, which can take weeks

    · Extremely unresponsive to customers. We started a claim/complaint in Dec and did not receive resolution until the following April. We also had to answer several of the same questions over that period of time, indicating they do not keep customer files even though most correspondence was via e-mail.

    · Conditioner touts of being able to condition (eliminate the effect of scale, not soften) water up to 45 grains of hardness, our water was around 18 grains and there was no evidence or reducing or eliminating the effect of scale. The company also states the media within the conditioner has a “5 year media performance warranty”. They did send a new set of media after several attempts to convince them that the system we had was not functioning properly…new media did not work either

    • Rachel, I am so sorry you had a negative experience with them and will definitely pass on these concerns to the company, though I’m glad it sounds like it is working now. We were able to install it relatively easily, and I have also had friends who had plumbers install for a reasonable price. If you can offer more specifics about the problem you experienced, I will make sure to research that more in depth and add any necessary information to the post, as well as bring up the specific concerns with the company. Thanks for reading!

      • Hello, is Wellness Mama, or the Wellness Mama website, at all affiliated with Radiant Life Company? Has Wellness Mama received money, gifts, or discounts from Radiant Life to promote their product?

        • I am an affiliate for Radiant Life (my full affiliate disclosure is here and I receive a small commission from Radiant Life if someone purchases a product through my link. I’ve used their products long before I ever promoted them or become an affiliate and would recommend them with or without an affiliate program. I have not received discounts, gifts or other compensation, nor have I ever written a sponsored post for them or any other company. I also purchase any products I review and only consider linking to them if I truly love them. Based on your previous comments, I love that you are so passionate about making sure water filters are high quality, I am too. On the topic of disclosure, I’m curious if you have any association with a water filter company or have a background in water sciences, as all of your comments have been about water filters and you aren’t exactly my normal audience…..

  55. Hi- so what would be the upshot of this, for a $3-500 system wanting flouride removal? What would be a recommendation?

  56. Has the whole house water system review been posted? Thanks

  57. Does anyone know of or have used a Kangen Water filtration system? I heard they were the best, but super expensive.

  58. Hello my name is Loren, I am doing some water research for my class and it has to do with the town I live in. The water at my house and several neighbors etc often comes out yellow. In February the city distributed letters to the residents making them aware of water violations. The problem is that our town uses chlorine to disinfect the water and it is reacting causing harmful byproducts called THM which can lead to cancer and various complications at high consumption. I also think that when the water is distributed in the town plumbing that some of the rust or things contaminates the water after it has been “cleaned.” So, I was wondering if you think the city could provide filters such as these for our homes and that would improve the quality of life?

  59. You mention removing arsenic as a reason to have a filtration system but it doesn’t appear like this system filters arsenic, at least I can find any information on the site about it. Can you clarify/confirm? Thanks!

  60. My only question is about the RL storage tank. The RL website refers to “butyl rubber bladder”, which is similar to other RO systems. When I research butyl rubber it seems to be produced by Exxon Mobil Chemical. This is my concern. I called RL and their team said they would call me back with feedback weeks ago, but never did. I am onboard with their great water process, but then storing that water in a chemical rubber bladder I need more information on.

    When I research butyl rubber more there are references to toxicity and metals as well, therefore I must be missing something.

    From your strong relationship with RL, could you please try getting insights for us? I am happy to purchase through the affiliate link as soon as possible because I think it is a fair model for providing valuable content. We just have young kids with sensitivities and want to ensure I know what we are providing them.

    Thanks very much.

    • Great question. I will follow up with them as well and update the post as soon as I have answers. Thanks for bring this up.

  61. Hi Wellness Mama,

    I have been following this blog for quite a while now. I was wondering what you thought of the aquasana 3 stage system. It leaves the minerals in the water and looks pretty good. I thought you might spot something negative on it that I missed. Its pretty affordable

    • Following, I am wondering the same.

  62. It’s important to note on my previous comment those removal rates of heavy metals and such are based on spiked samples which would be typically higher than municipal tap water.

    I would suggest calling Water Pure Technologies and getting the actual test results. Virus, Bacteria, and Cysts had removal rates greater than EPA and WHO requirements for water purification

  63. sorry if this is a dumb question, but – if this is the water that comes out of your sink then how do you get cold water to drink? Do you have to put a pitcher in the refrigerator? Adding ice would seem to defeat the purpose. We use to drink water out of the fridge dispenser. I’d love to be able to get this great quality of water in my ice cubes without filling trays. Again, sorry if this is a totally dumb question.

  64. Hi Katty, I am trying to get more information on the RL filter and they are really prize. Another think I am concerned about is that they don’t have reviews. Reading the reviews is very important to me. I really need to get a whole house filter but seeing that they do not have reviews make me think twice. Tell me Katty what do you think!

    • I purchased their whole house filter over a year ago and we absolutely love it. Never had any issues at all…

  65. Thank you! I am going to keep asking them questions and hopefully It is a good option. We do not make a lot of money and I like to save by buying our cloths at garage sales and saving money for organic food and good supplements and now we are considering a whole house filter. I want to buy a good one. I trust most of what you recommend so hopefully Katty, this water filter is our best option.

  66. I just purchased a Royal Berkey from your recommendation. I have a question though- we live in a rental home and have a very basic kitchen faucet with a very shallow sink. Will I be able to fill the Berkey in it? Or do you have to have a faucet that is able to extend?

    And for 3 people, do you think I’ll need to fill the Berkey each night (with regular water consumption) or will it last more than a day?

    • I’ve used either the dish sprayer or a jug to fill mine in the past…

      • Ok, thanks. We don’t have a dish sprayer and a jug would never fit under the faucet either, so looks like I need to go kitchen faucet shopping! Worth it for clean water though. Hope I love the Berkey as much as others do!

  67. I’ve read in different articles that Berkey isn’t NSF certified, do not have any recent lab tests on their filters, nor provide micron rating for their elements. I’ve checked and Berkey in fact isn’t NSF certified. I really don’t think this is a product you should be endorsing.

    • NSF certification is sort of bunk in that it costs about $35k to get a NSF 42/53 certification. The Brita’s and Zero’s of the world will tell you you need them but certified labs will do the test to the same procedure (it’s published) but without the fancy NSF sticker for a fraction of the cost. Ask the company for lab data and who certified them. Then thank them for saving that money to pass along to you rather than give to Steph Curry (Brita Sponsor) and N$F to influence you about something other than the water quality.

  68. Lots of these awesome products are only available in the United States. Anyone have advice on UK products?

  69. I use the REVIVAL water pitcher because I wanted a solid carbon filter like the Berkey only shrunken down to fit in a pitcher in my refrigerator. It filters Fluoride (rare for pitchers) and lasts 200 gallons (much longer than other pitcher filters).

    They have options for alkaline, a regular tap water filter, and one that removes bacteria so it fits any needs you may have.

    They also sound similar to Radiant Life in that they are family owned, and very friendly. I’d recommend you check them out.
