PUR water filter review: which filter is certified for what

I went through PUR’s US store in its September 16, 2026 copy, the latest I could open. Each “Buy Now” button sends you to a retailer, so the table shows filters and listings, not prices.

The filter decides the listing, not the pitcher. PUR’s PLUS filter page says it fits all PUR and Beautiful by PUR pitchers and dispensers, and IAPMO’s certificate lists it “for use in all Pour throughs and disponsers [sic].” Put a PLUS filter in a basic PUR pitcher and you get the PLUS listing.

The PUR 44 Cup dispenser holds 2.75 gallons, the largest in the line.

In pitchers, PLUS is the filter with the lead listing. In faucet systems, the two filters share one listing. I read PUR’s IAPMO and NSF listings on October 14, 2026.

• Pitcher filter PPF900Z (PUR). NSF/ANSI 53 for benzene, cadmium, copper, ethylbenzene, mercury, methoxychlor, tetrachloroethylene, toluene and xylenes. NSF/ANSI 401 for linuron and trimethoprim only. NSF/ANSI 42 for chlorine taste and odor, zinc and particulate class VI. No lead, no PFAS, no microplastics.
• Pitcher filter PPF951K (PUR PLUS). The same plus carbon tetrachloride, simazine, lead and total PFAS under NSF/ANSI 53. Under NSF/ANSI 401, microplastics, BPA, estrone, ibuprofen, naproxen, nonylphenol and phenytoin. Under 42, particulate class I, the finest class. Both filters last 40 gallons.
• Faucet filters RF-3375 (PUR) and RF-9999 (PUR PLUS). One IAPMO row covers both: lead, mercury, total PFAS and VOCs. PUR says the PLUS filter’s extra Mineral Core is there for “a crisp refreshing taste.”

The PLUS pitcher filter needs more prep. PUR’s PLUS filter page says to soak it in cold water for 15 minutes, then hold it under running water for 10 seconds. The basic filter only needs a 15-second rinse.

PUR says the PLUS filter reduces “3x more” substances than “Brita’s leading pitcher filter” on its pitchers page and “5x more” on its filter page. The footnote on both names the Brita Standard filter, OB03, which isn’t listed for lead, not the Brita Elite, which is. The contaminants or other substances removed or reduced by this water treatment device are not necessarily in your water.

Yes, and by IAPMO and WQA too. PUR’s listings are held by Kaz USA, Inc., a Helen of Troy company, not by a company named PUR. On October 14, 2026, I found 1,260 rows under that name: 573 at NSF, 444 at WQA and 243 at IAPMO. Each certifier reads the same NSF/ANSI standards, but they don’t list the same claims for PUR.

• IAPMO, NSF/ANSI 53: lead, mercury, total PFAS and VOCs for the faucet systems, and lead and total PFAS for the pitchers and dispensers with the PLUS filter. IAPMO’s record shows this certificate took effect on November 13, 2025. All 53 PUR rows that mention PFAS are IAPMO’s.
• NSF, NSF/ANSI 53: asbestos, chlordane, lead, mercury, toxaphene and VOCs for the faucet systems. For the pitchers with the PLUS filter, NSF lists mercury, cadmium, copper and organic chemicals, but not lead or PFAS.
• WQA, NSF/ANSI 53: lead for the faucet systems and for the PLUS 11 Cup and other pitchers and dispensers, no PFAS.
• NSF/ANSI 401: microplastics for the PLUS pitcher filter and the faucet filters.

Older reviews predate the PFAS listing. Wirecutter’s pitcher guide, updated October 3, 2025, says the PUR PLUS filter “is an excellent filter, but it lacks PFAS certification,” and its faucet guide said no faucet filter was certified for PFAS as of November 2025. Both were true before the IAPMO certificate. PUR’s own pages are uneven too: its faucet filter page lists total PFAS, while the PLUS pitcher filter page, in its September 24, 2026 copy, doesn’t.

A lead listing doesn’t mean lead is in your tap water. A water test tells you what to filter for. The contaminants or other substances removed or reduced by this water treatment device are not necessarily in your water.

PUR rates its filters in gallons and months, whichever comes first. A filter change light on most PUR products flashes red when it’s time.

For the faucet filter, Walmart’s RF-9999 three-pack at $39, as shown on Wirecutter on October 14, 2026, works out to about $52 a year. For a pitcher, the PLUS filter PPF951K was $13.77 on Amazon on October 15, 2026. At 40 gallons or about 2 months each, that’s about $83 a year, or about $56 if you buy the 3-pack at $27.90.

Changing a faucet filter means twisting off the back cover, swapping the filter and closing the cover. For a pitcher, soak the PLUS filter, twist it into the reservoir and press the bottom so it locks. To reset the light after a change, PUR’s support page says to hold the button for 5 seconds. If water filters slowly, PUR says to shake the filter until the granules shift.

PUR warns that “off-brand” filters “are not tested nor certified” to filter the same. The listings above cover PUR’s own filters only, so a compatible filter from another brand needs its own listing.

Fluoride: no. None of the 1,260 PUR listing rows I read names fluoride. Fluoride reduction is certified under NSF/ANSI 58, the standard for reverse osmosis systems.

PFAS: yes for faucet systems and PLUS pitchers, by IAPMO. The claim is “total PFAS” under NSF/ANSI 53, in IAPMO’s certificate only. NSF and WQA list the same products without it.

Bacteria and cysts: PUR says no. Its pages say “Like other leading brands, PUR does not filter microbes,” and the support page says not to use a pitcher with water that’s microbiologically unsafe or of unknown quality without disinfection. NSF does list three PUR faucet models, PFM244W, PFM310M and PFM410F, for cyst reduction under CSA B483.1, the Canadian standard. That listing covers those three models only.

Hot water: keep it cold. PUR says pitcher filters can be damaged above 82°F (28°C). Wirecutter gives a 100°F limit for the faucet systems: switch to unfiltered for hot water.

I read the Amazon review summaries for the PUR PLUS 11 Cup pitcher and both PLUS faucet systems on October 14, 2026. Owners like the taste and the easy install. Leaks are the most repeated complaint on all three.

Taste wins. On the PLUS 11 Cup pitcher (4.3/5 from 3,534 ratings), 147 of the 159 reviews that mention taste are positive. On the faucet systems, 555 of 616 (vertical) and 215 of 243 (horizontal).

Installing is easy. On the vertical faucet system (4.4/5 from 11,046), 693 of 715 reviews that mention installation are positive. On the horizontal (4.3/5 from 8,312), 258 of 294.

Leaks are the weak spot. 221 of 230 pitcher reviews that mention leakage are negative, along with 447 of 542 on the vertical faucet system and 254 of 289 on the horizontal. The faucet systems also draw durability complaints: 412 of 529 (vertical) and 202 of 244 (horizontal). On the vertical model, 126 of 222 reviews that mention stability are negative.

Testers liked it too. Wirecutter, which dropped PUR from its pitcher picks over PFAS, still says “We like the design of Pur’s pitchers and dispenser the most of any we’ve tested.” In the Serious Eats faucet test, the PUR took several tries before it sealed. Wirecutter’s never leaked.

PUR doesn’t publish its warranty terms on its product pages. The Amazon listing for the vertical faucet system, FM-3700, gives a 2-year limited warranty. The horizontal model’s Amazon listing doesn’t state one. For pitchers and dispensers, PUR’s support page offers a registration form, not a term.

To register, PUR asks for the product name or model number, place of purchase and the date code, so keep the receipt and the box. Returns are set by the store you buy from, since PUR sells through retailers. PUR’s consumer line is 1-800-PUR-LINE.
