Quick Answer: PUR’s Plus lineup — pitcher, faucet mount, and 30-cup dispenser — is certified to NSF/ANSI 42, 53, and 401, covering chlorine taste, lead and other health-effect contaminants, and emerging contaminants like PFAS and microplastics. The PUR PLUS 11-Cup Pitcher (about $25) is the best all-around buy for most households; step up to the PUR PLUS Faucet Mount (about $26 to $38) for on-demand filtered water at full flow, or the PUR PLUS 30-Cup Dispenser (about $30 to $35) if you’re filtering for four or more people. Filters are inexpensive but short-lived — about 40 gallons/2 months for the pitcher and dispenser, 100 gallons/3 months for the faucet mount — so budget three PUR filters for roughly every one long-life Brita Elite filter.
PUR has been a mass-market name in home water filtration since 1986, and it’s now owned by Helen of Troy (marketed through Kaz USA), the same corporate parent behind Vicks, OXO, and Braun — not a private-label import. That scale is also why PUR ended up in a real legal fight: Brita’s parent Clorox tried to use a patent to keep PUR filters off shelves entirely, and lost. Below, we break down PUR’s three core product formats, what each is actually certified to do, what the filters cost to run, and where the brand’s real limits are.

PUR by the numbers
- PUR’s faucet mount filter is dual-certified by both NSF and WQA to NSF/ANSI 42, 53, and 401 — per FilterPicks’ 2026 lineup review, an unusually deep certification combination for a filter that costs under $40, and one most rival faucet filters don’t match.
- NSF/ANSI 401 certification does not mean a filter removes every pharmaceutical, pesticide, or microplastic — per TapWaterData’s certification database, the specific compounds covered are tied to the individual tested model, so PUR’s 401 badge on the pitcher isn’t automatically identical to the badge on the faucet mount.
- Brita’s parent Clorox filed a Section 337 patent complaint at the U.S. International Trade Commission seeking to block imports of Helen of Troy’s PUR filters (and Costco’s Kirkland-brand filters) over a fast-flow lead-reduction patent — an administrative law judge initially ruled for Brita, but the full ITC reversed that decision in 2023 and found the patent invalid, a ruling the Federal Circuit affirmed in October 2025.
- A PUR pitcher filter is rated for 40 gallons or 2 months, versus the 120-gallon, 6-month rating on a Brita Elite (Longlast+) filter — PUR’s faucet mount narrows that gap somewhat at 100 gallons per filter.
- PUR was created in 1986 by Minneapolis-based Recovery Engineering, sold to Procter & Gamble in 1999 for roughly $213 million, and acquired by Helen of Troy in December 2011 — three full corporate ownership changes in under 30 years, longer than most water-filter brands have existed at all.
1. PUR PLUS 11-Cup Pitcher — Best Overall
PUR PLUS 11-Cup Water Pitcher with Lead-Reducing Filter
- NSF and WQA certified to reduce over 70 contaminants, including lead (NSF/ANSI 53), chlorine taste and odor (42), and PFAS/microplastics (401).
- MAXION filter media adds natural minerals for taste without a plumbed-in connection or installation.
- Fits standard refrigerator door shelves; most models include an electronic or lever-style filter-change reminder.
- Filter (PPF951K) rated for 40 gallons or 2 months — plan on replacing it roughly three times as often as a Brita Elite.

The 11-cup pitcher is PUR’s default recommendation for most households, and it earns that spot on certification depth for the price: NSF/ANSI 42, 53, and 401 covers taste, lead, and emerging contaminants at roughly the cheapest entry point in this category. The trade-off is filter life — at 40 gallons per cartridge, a family that drinks and cooks with filtered water will burn through filters noticeably faster than with a long-life rival. If you want the widest contaminant list PUR sells and don’t mind the more frequent replacement rhythm, this is the pick; if filter-change frequency matters more to you than upfront price, weigh it against the Brita Elite in our head-to-head comparison.
2. PUR PLUS Faucet Mount — Best for On-Demand Filtered Water
PUR PLUS Faucet Mount Water Filtration System
- Attaches directly to most standard kitchen faucets in minutes, no plumber or cabinet space required.
- Horizontal swivel design lets the filter housing fold flat against the faucet when not in use.
- Dual-certified by NSF and WQA to NSF/ANSI 42, 53, and 401 — the same three-standard set as the pitcher, at more than double the filter life.
- Filter (RF9999) rated for 100 gallons or 3 months, versus 40 gallons/2 months on the pitcher and dispenser filters.
The faucet mount is the better everyday tool if you’re tired of refilling a pitcher reservoir: water comes out filtered at close to full tap flow, on demand, with a simple flip switch to bypass the filter for non-drinking use like filling a pot. Its RF9999 filter’s 100-gallon rating means it costs less per gallon to run than PUR’s own pitcher, even though the hardware costs slightly more upfront. The catch is the same one every faucet filter shares: it only serves the one sink it’s mounted to, so a second bathroom or a well-water supply line needs its own solution — and if you want filtered water at full pressure for cooking and a dedicated chilled tap, an under-sink filter is the next step up.
3. PUR PLUS 30-Cup Dispenser — Best for Households of 4+
PUR PLUS 30-Cup Water Filter Dispenser
- Nearly triple the reservoir of the 11-cup pitcher, so fewer refill trips for a family of four or more.
- Slim, space-saving body designed to fit refrigerator door shelves despite the larger capacity.
- Uses the same PPF951K filter as the pitcher — same 40-gallon/2-month rating and the same 70+ contaminant certification.
- No faucet installation or plumbing — gravity-fed, dishwasher-safe body.
The dispenser is PUR’s answer to the biggest pitcher complaint — constant refilling — without asking you to touch a faucet or a cabinet. Because it shares the same PPF951K filter as the 11-cup pitcher, you’re not trading away any certification depth for the bigger reservoir; you’re just filtering more water between refills. It’s the natural upgrade once a household outgrows an 11-cup pitcher’s daily refill count, and it remains fridge-door-friendly despite holding nearly three times the water. The filter-life math doesn’t change, though: budget the same 2-month replacement rhythm as the pitcher, just spread across more ounces poured per fill.
4. PUR RF-9999 Faucet Filter (6-Pack) — Best Value / Lowest Cost Per Gallon
PUR RF-9999 Faucet Mount Replacement Filter, 6-Pack
- Six filters covers roughly 18 months of faucet-mount use at the rated 100 gallons/3 months per filter.
- Same dual NSF + WQA certification to 42, 53, and 401 as a single RF9999 filter — buying in bulk changes nothing about filtration.
- Universal fit across PUR and PUR Plus faucet mount systems, so it works whether you bought the horizontal or vertical body.
- Lower cost per gallon than buying single filters repeatedly, and far fewer reorders than the pitcher's 2-month cadence.
If you’ve already committed to the faucet mount, buying filters six at a time is the easy way to lower your real cost per gallon and stop getting caught with an expired cartridge. At 100 gallons per filter, six filters cover roughly 600 gallons — for a household of four drinking and cooking with filtered water daily, that’s close to a year and a half without a reorder. It’s a strictly logistical upgrade, not a filtration one: the NSF/ANSI 42, 53, and 401 certification is identical to a single filter, so there’s no performance reason to wait.
The honest take: where PUR wins and where it doesn’t
PUR’s certification story is genuinely solid for the price — NSF/ANSI 42, 53, and 401 across the whole Plus line means chlorine taste, lead, and a defined set of emerging contaminants are independently verified, not just marketing copy. The faucet mount’s dual NSF + WQA certification is a real differentiator few sub-$40 faucet filters match. PUR also survived a genuine legal threat intact: Clorox’s Brita tried to use a 2012 patent to block PUR imports through the ITC, an administrative law judge initially agreed, and the full Commission still overturned it — a ruling the Federal Circuit upheld in October 2025. PUR filters stayed on shelves the entire time.
The honest limits: PUR’s filters are short-lived compared to the category’s long-life leaders. A pitcher or dispenser filter lasts 40 gallons/2 months against a Brita Elite’s 120 gallons/6 months, which usually erases PUR’s lower sticker price once you run the annual cost-per-gallon math. And NSF/ANSI 401 certification, while real, doesn’t mean blanket removal of every emerging contaminant — check PUR’s own contaminant chart for the specific compound you’re targeting before assuming coverage. If PFAS in your specific water supply is the primary worry rather than a general hedge, a certified reverse osmosis system or a filter from our best water filter for PFAS guide will get you deeper, membrane-level reduction than any pitcher or faucet filter.
The bottom line
Buy the PUR PLUS 11-Cup Pitcher (about $25 to $30) if you want the cheapest certified entry point into PUR’s lineup. Step up to the Faucet Mount (about $26 to $38) for on-demand filtered water at full flow and a longer-lived filter, or the 30-Cup Dispenser (about $30 to $35) once an 11-cup pitcher means refilling too often. Whichever format you pick, buy the RF-9999 6-pack once you’ve committed to the faucet mount — it’s the same certification for a lower cost per gallon. And if you’re still deciding between brands rather than PUR models, our Brita vs PUR comparison and Brita vs ZeroWater comparison cover the head-to-head trade-offs in full.
