What are the best home water filters for toxic PFAS “forever chemical” filtration? Per- and polyfluoroalkyl substances (aka PFAS “forever chemicals”) have been detected all over the United States in water systems in advisory levels. What do you do if your local well or water district has detectable levels of PFAS? You should get a water filter as soon as possible, but which ones are the most effective? You’ve trusted Mamavation to bring you topics like safest cookware without PFAS and nanomaterials, safest period underwear without PFAS, safest ketchup brands without detectable PFAS, and safest parchment paper without PFAS, now join us for the best water filters for home use that filter out toxic PFAS “Forever Chemicals” based on consumer studies.

Toxic PFAS “Forever Chemicals” Found in Over 2,800 Locations & All 50 States in the U.S.
Per- and polyfluoroalkyl substances (aka PFAS “forever chemicals”) include several thousand chemicals that have been used for over 50 years for a variety of things like stain and water repellency in jackets & furniture, lubrication of manufacturing equipment, wiring in electronics, non-stick coatings in pans, grease resistance in food packaging, and grease fire fighting foams at military bases and airports. As a result, these chemicals have been detected in our air, water, groundwater, soil, and household dust.
According to a recent study by the Environmental Working Group, as of August 2021, 2,854 locations in 50 states and two territories are known to be contaminated with PFAS “forever chemicals.” The Environmental Protection Agency (EPA) has known about the health hazards of PFAS for decades but has failed to limit PFAS discharges into the air and water or set cleanup standards until just this week.
Mamavation joined a press conference on Monday, October 18th with the Environmental Protection Agency (EPA) to discover there was some forward progress being planned to address these issues, but in our opinion, they are VERY late getting to the table on this. We are thankful they have finally decided to make plans of action, however, for the purposes of your family, this may be too late. Based on the prevalence of the contamination already present in the United States, you may need to take immediate action to protect your family.
Toxic PFAS “Forever Chemicals” Have Been Linked to Numerous Human Health Concerns
PFAS “forever chemicals” are pretty much everywhere, which is why they are referred to as being ubiquitous. To underscore that point, researchers have found that 98% of people in the United States have some of these chemicals (PFOS, PFOA, PFHxS, and PFNA) inside their bodies. Coupled with the fact that close to 100% of samples of breastmilk show traces of PFAS, it’s apparent how ubiquitous they really are.
These chemicals are also persistent, which means they build up in your body over time and do not go anywhere for several years. Therefore it’s very important to minimize the amount of PFAS chemicals you are exposed to, even if those levels are very small. Unless you avoid PFAS, your exposure level would only increase over time, which can lead to disease.
Here is the list of health problems (PFAS) perfluorinated chemicals are linked with.
- reduction in immunity
- metabolic diseases like obesity & diabetes
- reduced vaccination response
- cardiovascular disease
- affect the growth, learning, and behavior of infants and older children
- increased risk of allergies & asthma in young children
- lower a woman’s chance of getting pregnant
- increase the chances of miscarriage
- low birth weight
- increase cholesterol levels
- low sperm count
- smaller penis size
- increase the risk of cancer like testicular & kidney cancers
- thyroid disease
If you’d like to talk to your doctor about your own exposure to PFAS, the Agency for Toxic Substances and Disease Registry, a division of Community Health Investigations has created this fact sheet to use.
How Prevalent are Toxic PFAS “Forever Chemicals” & What To Do If You Find Them Locally
Due to the widespread nature of PFAS chemicals and increased scrutiny, long-chain per- and polyfluoroalkyl acids (PFAAs) have been phased out of production and replaced with short-chain “current use” PFAAs and per- and polyfluoroalkyl ether acids (PFEAs), such as GenX, ADONA, and F-53B, and these chemicals are becoming very prevalent in our environment. It’s important to also remember that even though chemicals like perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) have been phased out, they are persistent so they are still being found in drinking water, soil, and ambient air.
However, it’s surmised by researchers that the main exposure pathway for PFAS “forever chemicals” is through ingestion of contaminated drinking water. But despite all the increased awareness, PFAS are repeatedly detected at elevated levels in treated drinking water because they are not always removed in full-scale water treatment plants. These water treatment plants would need to use expensive technology combining the following methods to be successful and not all have these technologies:
- Granular activated carbon (GAC) absorption
- Anion exchange
- High-pressure membrane filtration, such as nanofiltration and reverse osmosis filters
First, check the water database from the Environmental Working Group to see if your local tap water has any PFAS contamination issues. If you find anything, you’ll want to purchase and maintain an at-home water filtration system that is particularly powerful at removing PFAS if these chemicals have been found in their area. This investigation will go over which types of residential water filters are effective at removing the following chemicals via a consumer study in 2020: GenX, PFBS, PFHxS, PFBA, PFOS, PFPA, PFHxA, PFHpA, PFOA, PFNA, & PFDA.
Next, choose from several types of water treatment systems like pitcher-style filters, sink reverse osmosis filter, whole house filtration with whole-house systems, ion exchange, carbon treatments, etc. We prefer NSF International certification, but you can find others independently tested (like in this post) to filter PFAS compounds. Not all systems will be able to handle different types of PFAS or high levels of PFAS, so do your research before buying.
Then finally, do your best to avoid PFAS in other areas of your home.
Consumer Study on Water Filters Compared Labs of Over 80 Units for PFAS “Forever Chemical” Filtration
In 2020 researchers, including Heather Stapleton from Duke University, published a study in the Journal of Environmental Science & Technology Letters called Assessing the Effectiveness of Point-of-Use Residential Drinking Water Filters for Perfluoroalkyl Substances (PFASs). This study looked at 89 water filters inside homes that had contaminated drinking water in North Carolina with PFAS pollution.
In order to assess each filter, the Wilcoxon-Rank sum test was conducted on the pre- and post-filter of each water system on the following PFAS chemicals: GenX, PFBS, PFHxS, PFBA, PFOS, PFPA, PFHxA, PFHpA, PFOA, PFNA, & PFDA. (Note: This is not an exhaustive list of all the PFAS compounds out there, but ones under a regulatory health advisory.)
Here were some main findings:
- On average PFAAs with greater chain lengths were more efficiently removed by activated carbon filters, however short-chain “current use” PFAS chemicals are reliably filtered by these same filters with the exception of dual-stage filters.
- All reverse osmosis and dual-stage use filters showed significant removal (p < 0.05) for PFCAs and PFSAs, reducing levels over 90% efficiency.
- All reverse osmosis and dual-stage filters showed removal of PFEAs at 97% efficiency.
- 74% of reverse osmosis and dual-stage systems were able to reduce GenX to a non-detect level.
- Activated carbon POU filters (including countertop, faucet, pitcher, fridge, and single-stage under sink filters) demonstrated greater variability in removing PFSas and PFCAs.
- Single-stage under the sink filters removed a majority of PFSAs at 84% but removed only half of PFCAs.
Mamavation’s Recommended Product: Aqua Tru Countertop Water Filtration Reverse Osmosis
After we categorized all the water filters, pitchers, and refrigerator filters, it was clear that there was an affordable option! Mamavation is recommending you get a countertop AquaTru system.

Mamavation’s Investigation of Water Filter Systems for Toxic PFAS “Forever Chemical” Filtration
Mamavation is reporting on the results from the consumer study in 2020 and dividing the systems into clear winners and ones that are “not our favorite” in terms of removing toxic PFAS “forever chemicals.” These units will remove PFAS levels in the water supply at various rates so pay attention to details.
- For the “best” category, we pulled systems that were tested against eight or more of the PFAS chemicals and had non-detect levels after filtration.
- For the “better” category, we pulled systems that were tested against less than 8 PFAS chemicals and had non-detect levels after filtration. This category does not mean they are “worse” per se, but just that there was no independent proof they worked against all the other additional chemicals.
- For the “not our favorite” category, we pulled brands that filtered PFAS, but not all of them.
We believe this arrangement will help consumers get their water to the safest levels.
Not Our Favorite Water Filter Systems for Toxic PFAS “Forever Chemical” Filtration
For the “not our favorite” category, we pulled brands that filtered PFAS, but did not bring all the PFAS chemicals to non-detectable levels. These water filters didn’t filter some of these PFAS chemicals: GenX, PFBS, PFHxS, PFBA, PFOS, PFPA, PFHxA, PFHpA, PFOA, & PFDA.

Best Water Filter Systems for Toxic PFAS “Forever Chemical” Filtration
These brands had PFAS at Minimum Detection Levels (MDL) meaning it was not detected when the filter was running. The following PFAS chemicals were accounted for: GenX, PFBS, PFHxS, PFBA, PFOS, PFPA, PFHxA, PFHpA, PFOA, PFNA, & PFDA. These water filters were tested against at least 8 of these chemicals and passed. There was some variance on what chemicals were present in the water at each home and if any were not present, we called that out for you as an FYI.

Hi! I tried to go to AquaTru with the link to purchase one, but nothing was deducted at checkout- is there a coupon code or something that I should be using? Thanks 🙂
Yes Im having the same issue. I think theyre trying to use the sale price of the item as the so called discount theyre giving you. I brought the aqua water purifier up on the internet not through their link and they were the same prices so…?
Try MAMAVATION or MAMAVATION10
Try MAMAVATION or MAMAVATION10
I would avoid that company if I were you. They are not transparent. Their product affected by blood work and my pet’s bloodwork.
An outstanding article with a mountain of data to back it up. Thank you for posting this. We are all at the mercy of the EPA which is slow in providing regulatory protection and guidance. We should all assume there are PFAS in our water supply and take necessary precautions to minimize the health risks. Public water suppliers were recently notified by the EPA to reduce these dangerous chemicals in our water. However, this will take time and money, something public utilities have limited amounts. I believe the best strategy, for now, is to use a RO system for your cooking/drinking and add Himalayan salt to your drinking water in order to get the minerals your body needs. Drinking just RO water is not healthy as it will leach minerals from the body as it passes through.
Clearly Filtered
The Clearly Filtered Pitcher is made of bpa-free Titan and is convenient for countertop filtration.
I like the amazing purity of its water. The filter eliminates most of the harmful toxins in our water, most of the Alzheimer’s causing aluminum from airplane chemtrails, most of the toxic fluoride and chloramine mandated by the City, and more! But healthy minerals are selectively retained. The huge list of contaminants (and its %) removed is listed at website.
https://www.clearlyfiltered.com/pages/performance-data-for-the-clearly-filtered-water-pitcher-and-filter
When filtering water, I ensure that the filtered water does not touch the filter. If it does, contaminants from the filter will seep into the water again. I do muscle testing (aka Kinesiology), and my muscle tests weak when the filtered water touches the filter.
TIP: Quickly move your fingernail around the edge of a new filter to prevent water seeping through the edge.
I noticed you recommend theAQUA TRU Countertop Water Filtration Reverse Osmosis – did you test the under sink option as well but you still think this countertop option is better?
KY. Did you ever get an answer. I was wondering the same thing. I would love the under counter model. Thanks
Lots of people were confused (as was I) by the “no absent chemicals” or “1, 2, or 3 absent chemicals”. I had to reread it several times to figure it out. I believe what Leah is saying is that those specific chemicals were absent/not present in the ORIGINAL water being tested by that system. Therefore, not finding it in the filtered water doesn’t tell you if that system is actually capable of filtering that particular chemical! So if your particular water at home does have that chemical that was absent, you won’t know if that brand will be able to filter it out for you. Therefore, the best system is one that had ALL the tested for chemicals present in the water prior to filtering, showing that that system is able to filter ALL of them. She also tends to show the brand she most recommends by underlining it and often gives a link with a coupon.
Correct me if I’m wrong, Leah.
isn’t it pretty relevant that the ZeroWater filter used in the study was a month old? for high TDS water, the ZeroWater filter isn’t really expected to last that long. i typically change mine every 2 weeks or so. great information here though thanks
Do you have a link to the published results for each filter? Maybe I missed it but I couldn’t find a link to the direct information.
Thanks
It seems people forget that reverse osmosis also removes all nutrients and minerals in your water. It’s so dangerous to drink if you don’t replace them.
You shouldn’t be getting all your nutrients from water? Add a pinch of Himalayan Sea Salt. What do you suggest?
i agree, i am confounded with the knowledge my tap water is harmful and i can’t find clean drinking water that won’t leach minerals from my body. I mean i have a whole house filter i spent thousands of dollars on in 2016 and now i find it hasn’t been protecting us from the radium chromium and other carcinogenic toxins found in my water ..we have been bathing in the toxic. I am so mad and frustrated. I am trying to do the right thing and it’s so hard and expensive.
Did you find another system that will remove the chromium, radium, pfas and so on. I’m looking for a quality home treatment system.
Exactly 💯
It is absolutely maddening.
I think “dangerous” is a strong word to use here. While, yes, we should absolutely be aware of our mineral levels/intake as they are vital to good health, I would consider the actual danger being the consumption of toxicants. Water is not our only source of minerals.
What are your thoughts on Springwell whole house system and under sink?
Hi Leah,
Did you mean for the url above: “check the water database” to go to the water database? Currently it simply comes back to this section on your recommendations.
High-pressure membrane filtration, such as nanofiltration and reverse osmosis filters
First, check the water database from the Environmental Working Group to see if your local tap water has any PFAS contamination issues. If you find anything, you’ll want to purchase and maintain an at-home water filtration system that is particularly powerful at removing PFAS if these chemicals have been found in their area. This investigation will go over which types of residential water filters are effective at removing the following chemicals via a consumer study in 2020: GenX, PFBS, PFHxS, PFBA, PFOS, PFPA, PFHxA, PFHpA, PFOA, PFNA, & PFDA.
I would be interested in learning more about whole-house filters that get rid of PFAs, fluoride and chlorine. Thanks!
P.S. This site seems a bit glitchy. Comments disappear or are flagged as duplicates when they’re not. Also, when reading these long articles I am frequently sent back to the top and need to scroll back through to figure out where I left off.
Can you check Epic Water Filters? They have testing on their website for PFAS for all of their products.
Please advise what you know about Kangen water machines, the water purified through them, etc.
Are they safe to use?
It’s unknown for this study. They did not include a Kangen machine.
Plus one for evaluation of Alexapure – love to know how it stacks up.
Thank you so much for these recommendations. I realize the independent data is limited to the types of filters used in this particular study, but if you ever do more research into water filters, I’d love to find out how the combination ceramic/carbon gravity filters perform, like the AquaCera CeraMetix-GF. That particular filter claims a reduction rate of >99% for Fluorinated Organic Acids (PFOA & PFOS), which is shown in their published lab results (https://cdn.shopify.com/s/files/1/0272/0661/files/16-112_AquaCera_Chem_Red_test.pdf?7672504941760631133)—but it sounds like it might be unwise to trust those numbers. I imagine the carbon element is doing most of the work of filtering PFAS, and the ceramic element doesn’t add much?
Clearly Filtered would be smart to get into this mix.
That’s what we have. We actually filter with an under the cabinet filter, then a Berkey and then a clearly filtered.
What are your thoughts on Pure Effects Filter?
We are waiting for some additional independent studies to hit before we update with some other brands.
What about clearly filtered? So Berkey doesnt filter any PFA’s?
I’d also like to find out about Clearly Filtered. They say they do remove pretty much everything
Did you folks ever get clarity on clearly filtered? I’m considering them but I’m not sure and wondered if other people had experience.
Same! Add an edit for clearly filtered please!
We just bought a house in St. Charles county, MO 63304, and today read an article in the Saint Louis Dispatch about ground water contaminated by vinyl chloride. So following….
Have you done any research on a clearly filtered water pitcher made w/ tritan plastic?
I have a clearly filtered and love it. I see quite a few people asked about them, but no one responded yet…hopefully they do soon, I’m curious!
Cyclopure now makes a PFAS filter that works with Brita pitchers.
Any updates on which GE fridge filters were good? We just got a GE Cafe fridge. Hoping we can use the ice from the ice machine!
Have you conducted any research on the RKIN reverse osmosis table top system? I own one and love it but wonder if you are familiar with their product. I prefer it over other tabletop units due to putting vital elements back into the water. Taste is important as well. Thanks so much for your time.
Thank you again for all the testing you’ve done. CuZn under sink water filters are relatively inexpensive ($115) and have sent me their test results on a wide range of contaminates. I would love to see an independent test done on it and other KDF/GAC Filters. Thanks.
+1 on reviewing CuZn!
Yes, I’m curious to know about CuZn as well! https://www.amazon.com/dp/B000923524?ref=myi_title_dp
Can you plz share their test results. Do they remove pfas?
Does their test report show they remove pfas？
Question: Many whole-house systems have tanks lined with HDPE. Is there any data on plastics leaching into these systems from the liners? It seems odd they would use plastic-lined storage tanks when the purpose of filtration is to remove the contaminants.
I’ve not seen a study like that before
I’m confused:
What do you mean by “absent chemicals?”
Does that mean that there were none of those present before filtering? Or that they were 100% filtered out; absent from the processed water?
Thank you!
It means those contaminants were not present in their water
Not present before or after the filtration? You didn’t answer the question completely.
They weren’t present in the water being tested in that area is how I read it… hope that helps.
I’m confused why you would recommend PUR if there are no absent chemicals.
This meant that all chemicals were present before filtration.
I’m still very confused, is NO absent chemicals better than 3 absent chemicals??
Following. I found that confusing as well.
Do you recommend any whole home filtration systems?
Thank you!
Hello! What I am hearing people do is get a Berkey and use ProOne filters inplace of Berkey. It also removes fluoride withoutthe need for a separate filter. ProOne is formally known as ProPur.
How does ProOne score with PFAS? Thanks!
I would also like to know more about whole house systems
I would also love to know more about whole house filters that filter PFAs and other nastiest like fluoride and chlorine.
I’m curious about the Pro One Big +. Have you tested any of these?
I was also wondering about the Pro One filters. I have a countertop one and when I researched prior to your research on PFAs, it was the one that seemed to remove the most contaminants. Did you research/test this brand?
Hello,
I was wondering about the clearly filtered water pitcher ?
I noticed they didn’t compare clearly filtered to these other filters
Quantitative product-specific reviews, rather than “didn’t remove everything” would have been helpful for consumers.
Unless you can capture the runoff and use it productively, such as in irrigation, reverse osmosis systems waste 4 gallons of water for every gallon delivered — not a great scenario in a drought.
Most folks don’t drink that much per day. The real water waste is in agriculture, especially when the produce is sold overseas. That means our water (in the form of fruits/veggies/hay) is being shipped overseas.
Hi, I’ve seen some articles note that reverse osmosis removes minerals that are essential to our body, but other articles dispute this. Any thoughts on this?
Thank you!
The reverse osmosis filter we recommended in this post has an option where it adds those minerals back. You are correct in thinking this can cause an issue if you drink lots of water, so make sure to purchase a system that adds these minerals back.
Hello, yes reverse osmosis removes just about everything in your water making it slightly acidic. You can always add an alkaline filter to any ro to add the healthy minerals back into your water and raise ph.
Well PFAS and microplatics are my real concerns and Aqutru done fantastic thing to minimize the level of PFAS and microplatic in it
The link for the discount on the AquaTru product doesn’t seem to be working. Has it expired?
Go to their website they are having a 25% off Black Friday sale
Thanks for this! Did you ever get the model of the GE fridge?
Question about the recommendations on the best Water Filter Systems for Toxic PFAS “Forever Chemical” filtration. What do you mean by absent?
For example, when you state “Culligan Reverse Osmosis (3 absent chemicals: PFPA, PFNA, & PFDA)” I found the wording confusing.
Does that mean that for the 3 absent chemicals – PFPA, PFNA, & PFDA …those were not detected but trace levels of GenX, PFBS, PFHxS, PFBA, PFOS, PFHxA, PFHpA, PFOA were in fact detected?
Any clarification would be greatly appreciated on the “absent chemicals” meaning. Thanks so much for your time effort and help.
Were the carbon filters on the various systems new or same age/amount of use – or were they at varying levels of previous usage/age?

Any clarification would be greatly appreciated.
What about the Lifestraw pitcher??
Will the Berkey work with four black filters?
None of the 89 homes tested were using that so I can’t be sure. I can only be sure of what was independently verified.
What about Mercola’s fluoride filter?
And Fluoride is also critical to remove but barely referenced in this post?
You never seem to address comments on your posts though…?
This post is not about fluoride, it’s about PFAS. They both contain fluorine but are different chemicals. PFAS is far more concerning.
I also want to see your results on clearlyfiltered.
This is great! Thank you! What about the plastic reservoir in the Aqua tru that you recommended? Will that cause BPA or bps of phthalates into the filtered water?
If you have issues with PFAS in your tap water, the plastic components are the least of your worries. If you do not have PFAS in your tap water, there are other systems that you may like more than this one. We recommended the filter here that has the best efficiency based on an independent study. (Not from studies paid for by the brand themselves.) But there are many other things your tap water can have that may make another type of filter more attractive to you. Take a look at the EWG water database and look into your zipcode to find out first, https://www.ewg.org/tapwater/water-filter-guide.php
Leah thank you for your hard work here! You did not reference the plastics used to house the filter and the filter pitcher where applicable. Many of these (e.g. Pur) are made of Tritan, which as you know is terrible. I’ve struggled to answer this question myself. Can this list be further filtered to consider the plastic parts contained in the filter housing and other parts that touch the water?
We aren’t a fan of Tritan, but in terms of PFAS, I think Tritan is a lower concern. I would say not to store this in direct sunlight and drink the water within a few days. Leaching happens when you apply heat, have high-fat content or there is some type of acid involved. But again, this post is just about PFAS. And that’s a BIG deal.
You mention the Berkey with 2 black filters. What about with 4 black filters?
Thank you for this! How bad exactly was Berkey?
The Berkey may be good for other things, but it’s not efficient in filtering out certain types of PFAS.

I can only be sure of what systems were indepedently verified in that study.
What about Radient Life water systems? Also Kishu charcoal sticks? Thanks!
They didn’t look into this brand.
Also looking for the same clarification “Tim” asked for on Dec. 8th. Please let us know, thanks!
Have you researched Radient Life water systems? How about Kishu charcoal sticks?
What about AlexaPure as a filter for PFAS?
There’s 3 different Hydroviv filters mention in this but when I ordered mine a couple months ago, they only had either under sink or fridge in line filter. Do you know which ones those fall under in terms of filtering PFAS since one type seemed to be missing several types while the other two filters did better?
This is great! I don’t see ClearlyFilteted on here?
They didn’t have that brand as part of the study in homes in North Carolina.
