Culligan with ZeroWater Technology 10-Cup Pitcher (ZEROP10)
Reader ratings
The only pitcher we reviewed with a certified fluoride claim, plus lead, total PFAS and nitrate. Filters are rated 20 gallons, so they cost the most per gallon of any pitcher here, and the water ends up low in minerals.
Best for People who want fluoride, nitrate, lead or PFAS reduced without a reverse osmosis unit, and who accept a higher filter cost.

How we evaluated it
Why we chose it What put it on our list
- IAPMO R&T lists ZEROP10 and its sister models under NSF/ANSI 42-2023, 53-2024 and 401-2023 (files W-17154 to W-17156, active, effective 2025-12-08). The 53 claims are cadmium, copper, fluoride, lead, mercury, total PFAS, hexavalent chromium and nitrate/nitrite.
- Culligan’s data sheet gives fluoride reduced 99.7% from an 8 mg/L challenge (limit 1.0 mg/L), lead 98.8 to 98.9%, total PFAS 99.7% and nitrate 99.1% from a 27 mg/L challenge.
- The data sheet names its PFAS test mix: PFOA, PFOS, PFHxS, PFNA, PFHpA, PFBS and PFDA.
- A TDS meter comes in the box, so you can see when dissolved solids start to get through and the filter is spent.
- The pitcher costs about $35 on Culligan’s own store, with replacement filters at $15.00 each in a 6-pack to $18.50 each in a 2-pack.
Trade-offs What to weigh before you buy
- It is the most expensive pitcher to run of those we reviewed. At the 20-gallon rating, filters cost about $0.75 to $0.93 a gallon. The TDS meter, not the calendar, tells you when to change one.
- It removes nearly all dissolved solids (Culligan says 99.9%), minerals included. The water is low in minerals, which suits some people less. See our article on whether reverse osmosis water is too pure for the evidence.
- Two ZeroWater generations are on sale. The older “legacy” filters on zerowater.com (pitcher ZP-010, about $38) are certified for lead, PFOA/PFOS, chromium and mercury, are rated 15 gallons, and have no fluoride claim on their data sheet. Check for model ZEROP and filter ZEROF.
What to know Details worth knowing first
Fluoride is the reason this pitcher is on the list. Reducing it usually means reverse osmosis, as our article on fluoride-free alternatives explains. ZeroWater’s five-stage filter uses ion exchange, and IAPMO R&T’s listing for the ZEROP models includes a fluoride claim under NSF/ANSI 53, alongside lead, total PFAS, nitrate and chromium.
Know which version you are buying. Culligan, which owns ZeroWater, now sells a newer line (model ZEROP, filter ZEROF) with the longer certified list. The older line still sold on zerowater.com has a shorter list and a 15-gallon rating. Match the model number to the listing before you buy.
The cost is the catch. A 20-gallon rating is about three weeks of filter at a gallon a day, and the meter tells you when to change it. If lead or PFAS is your only concern, a cheaper pitcher such as the PUR PLUS covers both. Check what’s in your water before choosing.

What the labels mean
- Verified We opened an independent record that confirms it: a certifier’s listing, a regulator’s list or a lab report. It is linked under Sources.
- Maker’s claim The maker says so on its own page or label. We read it but found no independent record.
- Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.
