🕵️Our Research

This section of the guide provides all the information you need to know about PFAs, including how to test for forever chemicals, and why you might need to remove them. We’ve also shared our testing and selection process for the products in this review.

🤔 What are PFAs Chemicals?

PFAs chemicals are a large group of manufacturing chemical compounds, including PFOS and PFOA, that are used in a variety of products, from cookware to carpets, fire fighting foams to creams and cosmetics. PFAs are known as “forever chemicals” because they have strong carbon-fluorine bonds that don’t degrade in the environment.

The Environmental Working Group (EWG) estimates that more than 200 million Americans could be drinking dangerous levels of PFAs in their water, and more than 40,000 municipal or industrial sites are potential sources of PFAs pollution into water supplies across the US.

Products that contain PFAs

🚰 Do I Need a Water Filter That Removes PFAs Chemicals?

Considering the EWG’s stats on PFAs in drinking water, it’s highly likely that your own water supply is contaminated with this chemical.

To find out the quantity of PFAs in your water, reach out to your local authority and request a water quality report.

Dangerously, the Environmental Protection Agency (EPA) currently doesn’t have a Maximum Contaminant Level for this chemical, so your water supplier doesn’t have to even reduce PFAs if they don’t want to.

Some authorities choose to follow the non-enforceable health advisory level of 70 parts per trillion both PFOA and PFOS set by the Environmental Protection Agency. In comparison, the Environmental Working Group recommends a health guideline of 1 ppt of forever chemicals in drinking water.

If you prefer, you can test your own water with a private laboratory.

PFAs chemicals have such dangerous health effects that you should remove them from your tap water even if they’re only present in trace amounts. Installing a drinking water filter is the safest and most cost-effective way to protect yourself against PFAs.

🚱 How Do PFAs Get Into Drinking Water?

PFAs chemicals have been gradually phased out in the US since an agreement was signed between the EPA and eight major manufacturing companies in 2006. However, the toxic chemicals are still frequently imported into the country. Not forgetting that PFAs are so-called “forever chemicals” – so even those from tens of years ago linger in the environment.

PFAs get into water by seeping through soils or being transported by rainwater into surface or groundwater sources that are used as public drinking water supplies. Standard water treatment practices can’t remove these forever chemicals, so they remain in our water supplies as they’re sent to our homes.

🩺 Why are PFAs Chemicals Dangerous to Our Health?

According to the EPA, the biggest health risks of PFAs exposure are:

  • Developmental delays and effects in children, such as behavioral changes, low birth weight, and accelerated puberty.
  • Reproductive effects, like fertility problems and high blood pressure during pregnancy.
  • Increased risk of some kidney, testicular, and prostate cancers.
  • Interference with hormones produced naturally in the human body.
  • Impact on the immune system’s response to infections, and reduced response to vaccines.
  • Risk of obesity and increased cholesterol levels.

🧪 How to Test for PFAs in Water

The best way to test for PFAs in your tap water is to purchase a private testing package from a laboratory.

We use SimpleLab Tap Score for all our water testing purposes. The cost of a PFAs water test is just under $300, so it’s not cheap – but you’ll get much more accurate results than you would from any other means of testing.

🙋‍♀️ Who This Guide is For

This guide is for:

  • Anyone interested in different types of water treatment for PFAs removal. We’ve shared multiple forms of filtration in this guide.
  • People with a varied range of budgets. We’ve shared options to suit small budgets, so this guide is for you no matter how much money you have to spend.
  • Anyone who wants to avoid untrustworthy manufacturers and invest in a reliable product from a manufacturer that has decades of industry experience.

📊 How We Chose

When researching and testing products for this guide, we focused solely on water treatment systems that are designed for reducing PFAs contamination.

We chose the filters on this list based on the ability to remove PFAs, feedback from customers, value for money, and overall quality.

PFOA and PFOS Removal Capability

First and foremost, if you’re looking for a drinking water filter that reduces PFAs, the filter should achieve this to an exceptional standard.

The more PFOA and PFOA a filter can remove, the better. We prioritized water filters that are capable of removing at least 90% PFAs, preferably up to 99% and beyond.

Customer Feedback

If you want to know how a product performs with everyday use, check out its customer feedback.

We scoured hundreds of customer reviews when deciding which filters to include in this guide. This helped us to narrow down our focus to products that were consistently praised by hundreds of customers.

Value for Money

Different types of filters have different costs to consider. For instance, some systems have multiple filters to change, while others have only a single filter. Some systems have longer filter lifespans than others. Some are hundreds of dollars to purchase, while others cost less than $50.

Rather than finding the cheapest products, we chose the filters on this list for the value for money they offered, based on their ability to remove PFOA and PFOS, their quality, and their reliability.

Overall Quality

The quality of the components in a filtration system determines every aspect of performance, including its reliability and lifespan.

We focused on filters that looked, felt, and acted the part. We also reviewed customer feedback to asses a filter’s long-term performance and durability with everyday use.

🧪 How We Tested

Originally, we analyzed the performance of all the products we reviewed with third-party laboratory testing, but this testing had its setbacks. Our water source was nowhere near as contaminated as the test waters used in official industry testing, so we couldn’t get a clear idea of the filter’s ability to remove PFAs.

For this reason, we now leave the testing to industry experts like the NSF, ANSI, the WQA, and third-party laboratories that test to the NSF’s stringent Standards. Our own testing assesses the everyday user-friendliness, reliability, and durability of a product, and we combine our results with professional testing data available online to get a clear understanding of a filter’s overall performance.

🧾 Buyer’s Guide: Selecting a Drinking Water Filter for PFAs Chemicals

If you’re narrowing your options and you want to find the most suitable PFAs filter for you, don’t make a purchase without considering the following things:

Other Contaminants Present

You know that you have a PFAs contamination issue in your tap water. But what else does your water contain? It’s highly likely that there are other impurities that your local city water treatment plants aren’t removing.

Most filters are capable of removing a range of contaminants, so look beyond PFOS and PFOA to other common impurities, like lead, chlorine, and other chemicals and heavy metals.

Filtration Method

Consider the treatment methods available for PFAs removal and make a list of your favorites. Would you prefer a filter installed directly at your waterline, providing filtered water on demand? Or do you prefer the convenience of a portable pitcher or countertop filter?

The filtration method also determines the percentage of PFAs the system removes, and what other contaminants it targets, as well as filter life, the upfront purchase price, and maintenance costs.


If you want to be absolutely certain that a filter can remove PFAs as advertised, look for an official NSF certification.

There are two NSF certifications that a water treatment system can have for the removal of PFOA and PFOS:

  • NSF/ANSI 53, for contaminants with health effects
  • NSF/ANSI 58, for reverse osmosis drinking water filters

To obtain an official NSF certification, manufacturers must submit their products for rigorous testing – and a certification is only granted if the product meets the NSF’s stringent requirements. Third-party testing to NSF Standards is still reassuring, but not quite as impressive.

Flow Rate

The flow rate of a filter depends on the type of system you opt for. If you don’t mind waiting several minutes for clean water, consider a gravity filter, such as countertop filters and water filter pitchers.

If you’d rather drink filtered water on demand, you’ll need a filter that’s installed at your water line, like a whole house filtration system or an under-sink filter.

Filter Capacity

The capacity of a filter refers to how much water a filter can produce at any time, and how long the filter will last before it needs to be replaced.

The size of your family, your daily water usage, and your maintenance preferences should all be considered when you’re choosing between different filter capacities.

Installation & Maintenance

Finally, installing and maintaining PFAs water filters is something that can’t be avoided – but some filters are much easier to install and maintain than others.

Portable filters, like pitcher filters, can be assembled in a matter of minutes, while whole house systems and under-sink reverse osmosis filters require a more complicated installation.

A water filter’s lifespan affects the frequency of maintenance. Some filters last for upwards of 6 months, while others last for 3 months or less, and some even last for 2 years or beyond.

❔ Frequently Asked Questions

What water filter will remove PFAs?

The best water filters for removing PFAS are reverse osmosis systems, certain carbon filters, and water distillers.

Do water filters filter out PFAs?

Not all water filters are guaranteed to reduce PFAs levels, so shop around and read guides like this one to invest wisely in the best filter for removing PFAs.

Does Brita water filter remove PFAs?

No, Brita filters aren’t designed to filter PFAs. These filters can only remove a small selection of contaminants, namely those that affect water’s taste and smell.

Does the Zero Water filter remove PFAs?

Yes, Zero Water pitcher is advertised to remove PFAs, but this filter isn’t quite as capable as the Clearly Filtered pitcher, so it didn’t make our list.

Does distilling water remove PFAs?

Yes. Up to 99% of PFAs is removed by distilling water. However, distillation is an incredibly lengthy process, so we didn’t include any distillers in this guide.

Do reverse osmosis filters remove PFAs?

Yes, a reverse osmosis filter can remove almost 100% of PFAs.

Can granular activated carbon filters remove PFAs?

It depends. Some activated carbon filters remove virtually all PFAS from drinking water. However, some types of activated carbon filters don’t reduce PFAs at all.

How can I reduce my PFAS exposure?

Aside from treating your PFAs contaminated drinking water, you can reduce your PFAS exposure by:

  • Avoiding using non-stick cookware, which is often manufactured with PFAs, and takeaway food packaging
  • Checking your clothes labels, especially the labels of water-resistant clothing, to ensure they’re PFAs- or PFC-free
  • Avoiding cosmetics and dental floss that use ingredients with PTFE or “fluoro” in their names

Does bottled water have PFAs?

Yes, PFAs have been found in bottled water, so you’re not necessarily safer if you exclusively drink bottled water rather than tap water.

Does boiling water reduce PFAs?

No. Boiling water will only cause some of the water to evaporate, increasing the concentration of toxic substances compared to the volume of water.
