The best water filters for lead

Every filter here has a lead claim on a certifier's own listing: NSF, WQA or IAPMO. A claim on the box or the maker's website doesn't count until a listing shows it. TapBuff has not tested these filters. They are ranked by the claims EPA says to look for, then by what each costs over five years at the maker's list price, for a household of three using 3 gallons a day for drinking and cooking.

A filter is not the first step. Lead usually comes from the service line and the plumbing in your home, so start with the free steps and a test of your own tap, in Lead in your water: what to do now.

Five-year cost for a household of 3 at the makers’ list prices, cartridges included. A plus sign means a part due in those five years has no published price.

What to look for on a listing

EPA's consumer tool for lead filters looks for two claims on the same filter:

• A lead reduction claim under NSF/ANSI 53. EPA describes it as reducing lead to 5 ppb or less. Its example data sheet shows the test: 150 ppb going in, no more than 5 ppb coming out, at pH 6.5 and 8.5. Reverse osmosis systems carry their lead claim under NSF/ANSI 58 instead.
• A Class I particulate claim under NSF/ANSI 42. EPA recommends looking for it as well, and CDC says a filter's certification should show both.

Two marks don't count. A claim under NSF/ANSI 42 on its own is not a lead claim. And NSF/ANSI/CAN 372 on a box means the product's own parts meet the lead-free limit; it says nothing about removing lead from water.

How the picks are ranked

Both claims first. A filter whose listings carry the lead claim and the Class I particulate claim ranks above one with the lead claim alone.

Then five-year cost. Makers rate a cartridge in gallons and in months, and you replace it at whichever runs out first. Each five-year figure is the maker's list price for the system plus every replacement due in five years. Where a maker publishes no price, there is no figure, rather than a guess.

The cheapest to own with both claims is an under-sink filter with one cartridge, rated 1,500 gallons or six months, at $48.99. A pitcher costs more to keep: the Brita Elite filter is rated for 120 gallons, about 40 days at 3 gallons a day, and one whose filter is certified for 15 or 20 gallons costs several times as much. The best under-sink water filters compares every under-sink filter TapBuff tracks, and the best faucet water filters every faucet filter.

The picks

Best for lead

Under-sink carbon

Express Water StreamLine Direct Connect System (USC001)

Best for the lowest five-year cost with both claims EPA looks for

Strengths

• Lead under NSF/ANSI 53 and Class I particulate under NSF/ANSI 42, on IAPMO's listing
• PFOA/PFOS, cysts and asbestos under 53 as well
• The lowest five-year cost of any filter here with both claims, at Express Water's list prices

Trade-offs

• No mercury, VOC or chloramine claim
• Feeds your own faucet, so dishwater and rinse water go through it too: above about 8 gallons a day it runs out before six months
• Filter rated 1,500 gallons or six months: at 3 gallons a day the six months come first, at $48.99 a filter

Most claims under the sink

Under-sink carbon

Brondell Coral UC300 Under Sink Water Filtration System

Best for lead plus PFOA/PFOS, chloramine and VOCs under the sink

Strengths

• Lead and PFOA/PFOS under NSF/ANSI 53 and Class I particulate under NSF/ANSI 42, on WQA's listing
• Mercury, cysts and VOCs under 53 as well, and chloramine under 42
• Three filters replaced as a set, rated 600 gallons or 12 months: at 3 gallons a day, about every 7 months

Trade-offs

• $79.99 a set, and the stages are not sold separately
• Fits under the sink with its own faucet, so it takes some installing

Best pitcher

Pitcher

Brita Tahoe Pitcher with Elite Filter (OB60, OB06)

Best for both claims in a pitcher

Strengths

• Lead under NSF/ANSI 53 and Class I particulate under NSF/ANSI 42, on WQA's listing
• The lowest five-year cost of the pitchers with both claims, at Brita's list prices
• Filter rated 120 gallons or six months, at $19.99

Trade-offs

• Only with the Elite filter. Brita's standard filter fits the same pitcher and has no lead claim
• At 3 gallons a day, a new filter about every 40 days, and a pitcher to refill by hand
• WQA lists slightly different claims for the same filter in other Brita pitchers, so these are for the Tahoe

Best faucet filter

Faucet mount

Brita Elite Water Filter Faucet System (SAFF-100/FF-100)

Best for both claims on the tap, for about what the pitcher costs

Strengths

• Lead under NSF/ANSI 53 and Class I particulate under NSF/ANSI 42, on WQA's listing
• Mounts on the kitchen faucet, so filtered water comes straight from the tap
• The lowest list price of the picks, at $32.49

Trade-offs

• Filter rated 100 gallons or four months: at 3 gallons a day, a new one about every 33 days
• Brita says the 100-gallon life starts after a 5-minute flush

Best dispenser

Dispenser

Brita UltraMax Dispenser with Elite Filter (OB24, OB06)

Best for more filtered water at a time than a pitcher holds

Strengths

• Lead under NSF/ANSI 53 and Class I particulate under NSF/ANSI 42, on WQA's listing, with the Elite filter
• Holds 27 cups
• The same Elite filter as the Tahoe pitcher, at $19.99

Trade-offs

• Only with the Elite filter. The same dispenser with Brita's standard filter has no lead claim
• At 3 gallons a day, a new filter about every 40 days

Fewest filter changes

Under-sink carbon

Multipure Aquaversa (MP750)

Best for a lead claim on NSF's own listing and the fewest filters to buy

Strengths

• Lead Reduction under NSF/ANSI 53 and Class I particulate under NSF/ANSI 42, on NSF's listing
• Filter rated 750 gallons or 12 months: at 3 gallons a day, seven filters in five years
• Cysts, mercury, VOCs and chloramine on its listings too

Trade-offs

• The $550 list price is for the base unit only. Multipure's below-sink kit with a faucet adds $70 to $90, and the five-year figure leaves it out
• No PFOA or PFOS claim, though some other Multipure models have one

Best reverse osmosis

Countertop reverse osmosis

AquaTru Classic (AT2000)

Best for lead plus nitrate, arsenic or fluoride, with no plumbing

Strengths

• Lead under NSF/ANSI 58 and Class I particulate under NSF/ANSI 42, on IAPMO's listing
• Arsenic, nitrate, fluoride, copper and chromium under 58 as well, and PFOA and PFOS under 53
• Sits on the counter and is filled by hand. No plumbing and no drain line

Trade-offs

• The water it rejects collects in the tap-water tank and has to be poured out
• The highest five-year cost of the picks
• Three filters, rated six months to two years; at 3 gallons a day they come due every 6 to 13 months

Every filter TapBuff tracks with a lead claim

Ranked by whether it also carries an NSF/ANSI 42 Class I particulate claim, then five-year cost: a household of 3 at the makers’ list prices, cartridges included. “No price” means the maker publishes none. A plus sign means a part due in those five years has no published price. Listings checked between Oct. 4, 2026 and Oct. 16, 2026.

Certified, but not picked

• Frizzlife SK99. Both claims, for $590 over five years, but no PFAS claim, and three filters on three schedules. The Express Water StreamLine carries both claims and PFOA and PFOS as well, for less.
• PUR PLUS faucet filter and PUR PLUS pitcher. Both carry both claims. The faucet filter's lead claim is on NSF's, WQA's and IAPMO's listings; the pitcher's is on WQA's and IAPMO's. PUR publishes no prices, so neither can be ranked on cost. The pitcher needs the PUR PLUS filter: PUR's basic filter fits it and has no lead claim.
• Reverse osmosis with a lead claim but no Class I particulate claim. The APEC RO-90, Bluevua RO100ROPOT-Lite and Waterdrop G3P600 and G3P800 carry lead claims under NSF/ANSI 58. The APEC costs $549 over five years, the least of any reverse osmosis system here with a lead claim. The best reverse osmosis systems compares every system TapBuff tracks.
• Pitchers with a lead claim but no Class I particulate claim. The ZeroWater 10 Cup Pitcher and the Culligan pitcher with ZeroWater technology carry lead claims under NSF/ANSI 53. Their filters are certified for 15 and 20 gallons, which at 3 gallons a day comes to $7,334 and $5,103 over five years, against $942 for the Brita pitcher. The best water filter pitchers compares every pitcher TapBuff tracks.

At the tap, not for the whole house

EPA names lead service lines, lead solder and brass faucets and fittings as the usual sources. A whole-house filter sits where water enters the home, so it can't catch lead the plumbing adds after it. EPA's tool covers filters at the faucet and pitchers, and no whole-house system in TapBuff's catalog carries a lead claim on a listing.

Use it the way EPA says

• Cold water only. EPA: "Do not run hot water through the filter." Warm or hot water also draws more lead from pipes and fixtures.
• Replace it on time. EPA says a cartridge used after it expires can be less effective at removing lead. Each pick above names the rating that sets its schedule, and the five-year cost calculator works out how often that is for your household.
