• The dispensing faucet is the most attractive we’ve seen in this price range — it looks and feels like a luxury fixture.
• It comes in a Chrome, Brushed Nickel and Oil Rubbed Bronze — we appreciate having choices.

Cons

• The filters are inexpensive, but they didn’t last as long as advertised for us, meaning more maintenance and expenses for you.
• If your sink or countertop doesn’t have a pre-drilled hole for the dispensing faucet, you may need a pro to add one at a significant expense.

My Take

Claryum filters are a good alternative to whole-house filtration systems when money is tight. The water is delicious, and our tests confirm it’s clean. But we ran the numbers, and the cost of frequent filter changes makes SpringWell’s whole-home filter a better long-term investment. The Claryum is our top pick for budget shoppers but opt for the SpringWell if you own your home and can spare the cash.

Buyer’s Guide to Choosing a Water Filter For PFAS “Forever Chemicals”

The government’s latest report on PFAS contamination is an eye-opener. According to the Environmental Protection Agency, it could be decades before your drinking water is safe.

If you’re one of the millions of Americans with “forever chemicals” in your water supply, the only real solution is a water filter. In this guide, you’ll find the expert guidance and product reviews you need to make a sound purchasing decision. We’re in your corner.

How We Select the Best Water Filters

It takes more than an ordinary activated carbon filter to remove PFAS. So, we did extensive research to identify the best filtration systems for PFAS removal based on their quality, features, certifications and value.

We poured over reviews, analyzed customer feedback and scrutinized independent test results to find filters with high PFAS removal rates and user-friendly features. After using them personally, we’re confident that these are the best filters for removing toxic PFAS and other hazardous chemicals from your tap water. If we wouldn’t use them in our homes, they’re not on this list.

Who Needs This Guide?

This guide is for anyone who wants to know more about PFAS contamination.

In it, you’ll learn:

• What forever chemicals are
• How they contaminate the water supply
• How they affect your health
• And what you can do about them

We’ll help you decipher uncomfortable technical jargon and sort out advertising claims.

We also discuss:

• Different types of PFAS water filters
• Which features to look for
• Price considerations and more

If you have questions, we have the answers.

What Are PFAS Chemicals?

PFAS is short for per- and polyfluoroalkyl substances. A revolutionary group of over 5000 man-made chemicals, they’re ubiquitous in a wide range of industrial, consumer and public safety products.

Developed in the 1930s, the carbon and fluorine atoms in PFAS create a virtually indestructible chemical bond, giving them valuable hydrophobic and hydrophilic properties that make products water-, oil- and stain-resistant.

You’ll find PFAS in:

• Fast food packaging
• Non-stick cookware
• Plastic bottles
• Carpets
• Upholstery
• Paint
• Ski wax
• Nail polish
• Deodorant
• Building materials
• Electrical wiring
• Batteries
• Fire-fighting foams
• Solar panels and more

How Do PFAS Get into the Drinking Water Supply?

PFAS are chemically stable. Unlike volatile organic compounds, they don’t readily evaporate. Under normal conditions, they take millennia to degrade. Meanwhile, they migrate easily, following the flow of rainwater through the soil and into private wells and public drinking water supplies.

Leading sources of PFAS pollution include factories, landfills and wastewater treatment facilities. Wastewater is a particularly insidious contributor. Most treatment plants don’t remove PFAS chemicals, so they’re recycled into the water supplies used to irrigate crops. And they contaminate biosolids, human waste used as fertilizer on the fields that grow your food.

In a 2017 study, the Food and Drug Administration (FDA) confirmed that elevated levels of PFAS were found in fish, meats and even chocolate cake purchased at supermarkets on the Eastern seaboard. A global problem, PFAS are almost impossible to avoid.

Why Are PFAS Chemicals Dangerous?

There are thousands of PFAS chemicals, but to date, only a handful have been adequately studied. PFAS was not expected to contribute to water pollution, so the issue took researchers by surprise.

Environmental science has come a long way since the dangers of PFAS contaminants were first discovered in the late 1990s, but quality research takes time. Many questions still remain about the health effects and toxicity levels of specific PFAS chemicals across different age groups.

Those we’re aware of, however, are linked to a broad range of serious human health concerns. The worst offenders, PFOA and PFOS (perfluorooctanoic acid and perfluorooctane sulfonate) have largely been removed from the market but will continue to persist in soil and water for decades.

Supported by peer-reviewed studies, their effects may include:

• Low fertility
• Preeclampsia — pregnancy-related hypertension
• Stomach ulcers
• Developmental delays in children
• Low birth weight
• Accelerated puberty
• Behavioral disorders
• An increased risk of kidney, prostate and testicular cancers
• Hormone-related disorders
• Liver disease
• Impaired immune function
• High cholesterol and more

Do I Need a Water Filter That Removes PFAS Chemicals?

The Environmental Protection Agency is taking strong action against PFAS pollution. But according to the Environmental Working Group, a non-profit watchdog organization, the damage is already done. Testing shows that as many as a third of Americans drink tap water containing at least one PFAS.

The EPA recently issued a health advisory for four PFAS chemicals, including PFOA and PFOS. But health advisories are not regulations. For now, the goal is simply to raise awareness about emerging contaminants while collecting data on the occurrence, testing, treatment and health effects of PFAS. But until authorities develop a legally enforceable Maximum Contaminant Level (MCL), municipal water suppliers aren’t on the hook for PFAS testing or removal.

And while soil cleanup is underway in several states where PFAS levels are high, it has yet to begin in most areas. Meanwhile, these dangerous chemicals that we know little about continue a slow creep into our water supplies.

As a consumer, there’s little you can do to avoid PFAS in the soil, air and food. But you can reduce your overall exposure by drinking clean water. Even very low levels of PFAS in water are potentially toxic because the health effects are cumulative. Every effort you make counts — especially if you have kids.

The bottom line is that we have an unpredictable environmental crisis on our hands with no clear solution in sight, making a home filtration system the best protection for you and your family against toxic PFAS.

How to Test for PFAS in Water

PFAS chemicals are measured in parts per trillion, so it takes cutting-edge equipment to get accurate readings. We recommend sending a water sample to a certified drinking water laboratory for analysis.

If you don’t have one nearby, try Simple Lab’s Tap Score PFAS Water Test. It covers 14 of the most common forever chemicals, including PFOA and PFOS.

The testing process is simple and affordable. Kits include everything you need. Just collect a sample of your well or city water and mail it to their laboratory in the postage-paid box provided. You’ll get results in about a week, including a list of steps to take next. It’s actionable information.

How To Choose the Best Drinking Water Filter for PFAS Contaminants

A drinking water filter should fit your needs, budget and lifestyle. We used these criteria to choose the best PFAS water filters.

PFOA and PFOS Removal Capability

PFOA and PFOS are the two most common PFAS contaminants in water, so filters with the highest reduction ratings will naturally be more impactful — don’t settle for less than 90%. The best filters on our list eliminate 99% or more.

Filtration Method

There are two general types of water filters — point-of-entry (POE) filters, whole-house systems that purify water throughout your home — and point-of-use (POU) filters, such as under-sink filters and water filter pitchers, that treat small volumes of water for drinking and cooking.

Whole-house filters are plumbed into your incoming water line, so every drop from every tap is clean. It’s a comprehensive solution if you own your own home.

But POU water filters can be equally effective without breaking the bank. Petite and portable, they’re a great option for nomads and renters. If you’re short on cash, six of our seven best PFAS removal filters are point-of-use systems starting as low as $90.

Build Quality

Price and build quality aren’t always synonymous. But, in general, you get what you pay for. The last thing you want is a water filter that leaks or cracks under pressure.

We look for quality plastics, thick gaskets and waterproof design elements that prevent leaks. A good warranty is a bonus. Flimsy filters made of inferior materials didn’t make the cut.

Flow Rate

A water filter’s flow rate is the maximum number of gallons it can process per minute. Rates vary based on the type of filter and the size of the fittings.

Flow rate is critical among whole-house filtration systems. If it’s too low, you’ll notice a significant drop in water pressure when more than one tap is in use. The industry average of 6-7 gpm is suitable for average-sized homes. But for large houses with four or more bathrooms, the higher the flow rate the better. For this list, we insisted on 9 gpm or more.

Flow rate also affects the performance of water filter pitchers and under-sink filters, like reverse osmosis systems. But the differences between models are negligible. Among POU filters, performance and quality matter more.

Filter Capacity

Filter capacity is how many gallons systems treat before filters need to be changed. A top-shelf whole-house filter can handle a million gallons or more between maintenance intervals, while a water filter pitcher treats just 50-100 gallons over one to three months between filter replacements.

Capacity matters less than capability when it comes to removing PFAS. But high-capacity filters are generally more convenient. A whole-house water filter produces gallons of clean water with the twist of a handle. You might refill a water filter pitcher two, three, or even four times daily to meet your drinking water needs.

The price of replacement filters also affects your long-term cost of ownership. Maintenance intervals for whole-house filters vary from 3-12 months or more — 1-3 months for POU filters. Frequent cartridge changes add up over time, so always do the math before buying a water filter.

Installation & Maintenance

Whole-house water filters are straightforward to install, but they require permanent changes to your plumbing system. We recommend hiring a professional if you’re not comfortable cutting pipes. It’ll cost you, but you’re better safe than sorry.

Any homeowner can assemble a water filter pitcher or countertop filter. Reverse osmosis systems are slightly more challenging. But they take more time than skill to install, and you’ll save hundreds in plumber’s fees.

Maintenance chores are relatively simple for both POE and POU water filter systems. Manufacturers go out of their way to make them foolproof.

Whichever type of filter you choose, however, timely maintenance is critical. A filter’s ability to remove PFAS drops dramatically if it gets clogged. University studies show that a poorly maintained activated carbon filter can even increase the concentration of PFAS in tap water, so choose a model you have the money, time and patience to upkeep.

Certifications

The EPA regulates water safety under the US Safe Drinking Water Act. And some states, like California, set even stricter standards. But neither tests nor certifies water treatment systems. For that, we rely on the National Sanitation Foundation (NSF).

NSF-certified products are independently tested and guaranteed to:

• Be structurally sound
• Contain no hazardous materials
• Meet performance claims

It’s the best protection consumers have against manufacturers that overpromise and underdeliver.

Several NSF standards apply to drinking water treatment systems, including:

NSF 42

Standard 42 applies to filters that remove taste and odor impurities. Most activated carbon filters fall into this category.

NSF 53

Standard 53 addresses contaminant reduction claims for substances with known health effects, like lead.

NSF 58

Standard 58 applies only to reverse osmosis filters and evaluates contaminant reduction claims for EPA-regulated substances.

PFAS, however, are not yet regulated, so how do these standards apply?

From 2016 to mid-2021, PFAS removal filters were covered under a temporary standard — P473. Since then, new test methods were approved and added to the NSF 53 and 58 testing criteria. The promotional material for some PFAS filters may still list P473 certification, and that’s okay. But NSF 53 and 58 filters are now equally effective for PFAS removal.

Other Contaminants Present

Most PFAS removal filters also eliminate other common drinking water contaminants from VOCs to heavy metals. But some do a better job than others. If your water test results were an unpleasant surprise, you’ll want to choose a filter thoughtfully.

Among whole-house filters, those with regular activated carbon media remove 70%-90% of PFAS. Models equipped with catalytic carbon and KDF eliminate 99% or more of forever chemicals plus other contaminants, including heavy metals like lead. Neither, however, removes fluoride or total dissolved solids. There’s always give and take.

Among point-of-use filters, granular activated carbon and reverse osmosis systems both remove PFAS. But reverse osmosis filters are far more efficient. And while they also remove fluoride and other heavy metals, they virtually eliminate total dissolved solids — the natural minerals that give drinking water a refreshing quality.

Removing forever chemicals is important, but it shouldn’t come at the expense of taming more dangerous contaminants. The health risks of PFAS increase with time, but they’re limited in the short term. Lead, however, can cause irreversible damage to the human body within months. Choosing a water filter is a balancing act.

Manufacturer Hype & User Experience

Manufacturers aren’t shy about hyping their filters. But there’s no substitute for the user experience, so we’ve examined customer feedback across dozens of websites to understand what’s most important to buyers.

We look for honest appraisals of quality and function from people who’ve owned a filter for at least six months. Most are remarkably fair. In general, positive reviews reflect satisfaction with a product’s performance as advertised. Nothing turns buyers off more than false or misleading claims.

We urge you to be cautious, however, when considering negative comments. Some folks are quick to leave dismal reviews because of issues that don’t reflect the quality of the product or the manufacturer, such as one-of snafus with the shipping company.

Others don’t do their due diligence when it comes to research. We weed out bad reviews from people who chose the wrong product in haste unless it was misrepresented by the company. Similarly, we look over owner manuals and installation instructions to see if “hard to install” criticisms are fair.

We set the bar high, however, for quality and customer service — so should you. Problems aren’t always the manufacturer’s fault, but how they deal with them reflects the service you can expect after the sale.

Best Value for The Money

Water filters with similar abilities may have vastly different price tags. It’s hard to know if you’re paying for valuable features or unnecessary bells and whistles.

Our selection process assigns more weight to performance, ease of installation and maintenance costs than convenience features. But no one filter is right for everyone. Lifestyles differ, so you need to consider what matters the most to you.
