Older homes have a lot going for them. Original hardwood, big windows, a yard with actual trees. What they don’t always have is great-tasting water. Old pipes and fixtures can leave tap water tasting flat, metallic, or like chlorine. Or maybe you just live in an area with poor water, and you’re looking for alternatives to buying cases of water.
Bottled water is a temporary and wasteful fix, and the cost adds up. In my house, I’d be walking around collecting half-empty bottles thanks to my kids and their friends, and then all that plastic ends up in the recycling bin. A good water filter fixes all of that, and the right one can also take care of something you can’t taste at all: PFAS.
PFAS, short for per- and polyfluoroalkyl substances and often called “forever chemicals,” are man-made chemicals that break down very slowly and can show up in drinking water. Some home filters are now certified to reduce them, but “certified to reduce PFAS” doesn’t mean the same thing on every box.

Best PFAS Filters by Setup
- Pitcher: PUR PLUS Pitcher & Dispenser Filter and Culligan with ZeroWater Technology are both certified for Total PFAS, the broadest PFAS claim. They’re the best fit for renters, small kitchens, and anyone who likes cold water from the fridge. Clearly Filtered is a solid pick if you want fewer filter changes, but it has a narrower PFAS claim.
- Faucet: The PUR PLUS Faucet Mount Filter is certified for Total PFAS. It only fits standard faucets, and it’s a good pick for busy households that go through a lot of water.
- Under-sink: Pentair FreshPoint is certified for Total PFAS, and the Waterdrop G3P800 is certified for the narrower PFAS claim. Both are best for homeowners who can install plumbing.
PUR PLUS is the one brand on this list certified for Total PFAS in both the pitcher and faucet versions, plus lead and microplastics. That covers both setups that work for renters, since nothing needs to be installed.
What “Certified for PFAS” Means
If you’re like me and you’ve stood in the filter aisle reading box after box, you know the feeling. Everything is certified to reduce something. Lead, chlorine, microplastics, PFAS, 99% of this, 5x more of that. It’s easy to get overwhelmed and walk out with nothing because you don’t know what any of it means. So here’s what to check.
PFOA/PFOS vs. Total PFAS
Most PFAS claims on filters fall under a standard called NSF/ANSI 53, but there are two different PFAS claims under it, and they aren’t equal.
The older claim covers just two types of PFAS, called PFOA and PFOS. Those are the ones you hear about most. The newer Total PFAS claim covers seven types, including those two. So a filter certified for Total PFAS has been tested against a lot more forever chemicals.
The box won’t always tell you which claim a filter has, but the performance data sheet will. Every certified filter has one, usually linked on the product page. If you see “Total PFAS” listed, you’ve got the broader claim. If you only see PFOA and PFOS, you don’t.
You’ll also want to look at who certified it. The three to look for are NSF (NSF International), IAPMO (the International Association of Plumbing and Mechanical Officials), and WQA (the Water Quality Association). They independently test filters and keep checking them over time. Phrases like “lab tested” or “tested to NSF standards” sound similar, but they usually mean the brand paid for a test, not that the filter is actually certified.
Best Pitcher Filters for PFAS
A pitcher is the easiest fix if you rent. Nothing to install, nothing to drill, and it fits in the fridge so your water’s always cold. It’s also a quick way to see how much money you’re saving by not buying bottled water.
PUR PLUS Pitcher & Dispenser Filter: Best Overall Pitcher for PFAS
PUR PLUS filters were certified by IAPMO in September 2026 to reduce 99.75% of Total PFAS. The same filter is also certified for 99.9% of lead and 99.8% of microplastics, making it the first pitcher filter certified for all three. If you live in an older home with aging pipes, that’s important.
Each filter lasts 40 gallons, or about two months. PUR’s Mineral Core technology keeps water tasting crisp instead of flat, which matters if bad taste is what sent you to bottled water in the first place.
One thing to know before you buy: it has to be the PUR PLUS filter. The standard PUR filter fits the same pitchers but isn’t certified for PFAS, so check the box for the PLUS label.
Culligan with ZeroWater Technology: Best for Very Soft Water
ZeroWater, now sold as Culligan with ZeroWater Technology, is certified to reduce 99.7% of Total PFAS. It also strips out nearly all the minerals in your water, which is why people tend to either love it or hate it. Some love the totally neutral taste. Others miss the minerals.
The catch is filter life. Each filter is rated for 20 gallons, and it can run out sooner if your water is hard, since the filter has to work through those minerals too. That cost adds up fast in a busy household.
Clearly Filtered Pitcher: Longest Filter Life
Clearly Filtered‘s big selling point is its 100-gallon filter, which works out to about four months for most people. That’s great if you don’t want to think about filter changes much.
On PFAS, though, it only has the older PFOA/PFOS claim, not Total PFAS. The brand also lists a long list of contaminants it targets based on its own lab testing, which isn’t the same as being certified for each one. Check the performance data sheet before you buy.
Best Faucet Filters for PFAS
A faucet filter makes sense if you go through a lot of water, cook with filtered water, or just don’t want to wait on a pitcher to refill. It screws onto the end of your faucet in a few minutes, no tools needed, and comes off when you move out. The one catch: it has to fit. It only works on standard, traditional faucets, so pull-down sprayers and specialty fixtures are out.
PUR PLUS Faucet Mount Filter: Best Faucet Filter for PFAS
The PUR PLUS faucet filter has the same certification as the pitcher version, with 99.92% Total PFAS reduction. It’s also certified for 99.70% of lead and 99.65% of microplastics. You get filtered water straight from the tap, and you can switch back to unfiltered for washing dishes.
Each filter lasts 100 gallons or about three months, so you’ll change it a lot less often than a pitcher filter. For a family, or anyone filling big water bottles every day, that’s usually the better value. Just make sure you’re using genuine PUR PLUS filters, since the certification only applies to those.
Other faucet filters have PFAS claims too, but some only have the older PFOA/PFOS claim, so check before you buy.
Best Under-Sink Filters for PFAS
If you own your home and don’t mind a little plumbing, an under-sink system is the most hands-off option. It filters water before it reaches the tap, and the filters last much longer than a pitcher’s. The tradeoff is cost and installation. Most need their own faucet or a connection to your water line, which usually means drilling, so they’re off the table for most renters.
Pentair FreshPoint: Best Under-Sink Pick for Total PFAS
Pentair FreshPoint is the under-sink pick with a certified Total PFAS claim. FreshPoint systems are certified by IAPMO to reduce up to 99.7% of Total PFAS, the same claim I’d look for in a pitcher or faucet filter.
FreshPoint comes in a few different setups, so you can match it to your water and your budget. Filter changes are tool-free, with color-coded cartridges that click in and out, so it’s hard to mix them up. Like any under-sink system, it needs a plumbing connection, so it’s best for homeowners.
Waterdrop G3P800: Best Tankless Reverse Osmosis
The Waterdrop G3P800 is a tankless reverse osmosis system, so it takes up less cabinet space than older setups with a big storage tank. It filters water fast, wastes less water than traditional reverse osmosis, and comes with a smart faucet that shows your water quality at a glance. Waterdrop says most people can install it themselves in about 30 minutes.
It’s certified by IAPMO for the older PFOA/PFOS claim, not Total PFAS. If you want the broader certification, Pentair is the better pick. But if you want a fast, space-saving system for a bigger household, the G3P800 is worth a look.
How to Choose the Right PFAS Filter for Your Home
Start with your home and your space.
Do you rent? If you can’t drill or change the plumbing, under-sink is out. That leaves a pitcher or a faucet filter, and both can be certified for Total PFAS.
Will a faucet filter fit? Take a look at your faucet before you shop. If it’s a pull-down sprayer or an unusual fixture, a faucet mount probably won’t work, and a pitcher is your best bet.
How much counter and fridge space do you have? Counters in small kitchens fill up fast. A slim pitcher fits in the fridge door and keeps water cold. A larger dispenser works if you have a fridge shelf to spare.
How much water do you go through? A single person or couple will do fine with a pitcher. A family filling water bottles, cooking pasta, and making coffee every day may be happier with a faucet filter that lasts 100 gallons.
Which PFAS claim does it have? Look for Total PFAS on the performance data sheet, certified by NSF, IAPMO, or WQA.
What switching from bottled water looks like
One 40-gallon PUR PLUS pitcher filter does the work of about 300 standard 16.9-ounce water bottles. A 100-gallon faucet filter covers roughly 750. That’s a lot less plastic to buy, haul home, and toss, and a lot fewer trips down the water aisle.
Wrapping It Up
Living in an older home or an area with bad water doesn’t mean you’re stuck with bad-tasting water or a fridge full of plastic bottles. For most renters, a PUR PLUS pitcher is the simplest way to get water that tastes good and is certified to reduce Total PFAS, lead, and microplastics. If your faucet takes a standard mount, the PUR PLUS faucet filter gives you the same certification with longer filter life. And if you own your home, an under-sink system certified for Total PFAS is the most hands-off option.
Whatever setup you choose, check the performance data sheet, look for Total PFAS, and make sure it was certified by NSF, IAPMO, or WQA.
