ZeroWater vs Brita: the Culligan ZeroWater pitcher is certified by IAPMO R&T for fluoride, Total PFAS, lead, chromium-6, mercury, and nitrate, a longer list than the Brita Elite carries. The Brita Elite is certified for lead in most Brita pitchers and costs far less to run.
The catch: Its filters cost $0.68 to $0.93 a gallon, about five to seven times the Brita Elite.

Culligan ZeroWater: IAPMO R&T files W-17154, W-17155, and W-17156. ZeroWater 10-Cup: IAPMO R&T files W-14819 and W-14820. Brita Elite (OB06): IAPMO R&T file W-13905 lists it for lead in 11 Brita pitchers, but not the Everyday OB46. Brita says the Elite reduces PFOA and PFOS, but none of IAPMO R&T, WQA, or NSF International lists that claim.
Does ZeroWater or Brita remove fluoride?
Only the Culligan ZeroWater, which is certified by IAPMO R&T for fluoride. The Brita Elite and the original ZeroWater 10-Cup have no fluoride claim. If fluoride is your reason for buying, check that the box says Culligan ZeroWater; older ZeroWater filters don’t fit the Culligan pitcher. See our fluoride guide.
Which is cheaper to run?
The Brita Elite, by a wide margin. Each filter lasts about 120 gallons, which works out to about $0.14 a gallon at brita.com’s $32.99 price for a 2-pack. The Culligan ZeroWater costs $0.68 to $0.93 a gallon at Culligan’s pack prices, with a filter certified for 20 gallons. On hard water a ZeroWater filter runs out sooner: Culligan’s own guidance gives 8 gallons or fewer above 400 ppm dissolved solids.
How does the water taste?
Brita water keeps its minerals and tastes like cleaner tap water. ZeroWater strips dissolved minerals along with contaminants, so many owners describe the water as flat. ZeroWater includes a meter that shows the dissolved solids reading, so you can see when the filter is spent.

ZeroWater or Brita: which should you buy?
Pick the Culligan ZeroWater if
Fluoride or PFAS is on your water report, and your water isn’t very hard.
Pick the Brita Elite if
Lead and chlorine are your main concerns, you want the fewest filter changes and the lowest running cost, and you like the taste of your tap water with the minerals left in.
Consider PUR too
The PUR PLUS is certified by IAPMO R&T for Total PFAS and lead. See Brita vs PUR vs ZeroWater.
Drink a lot of filtered water?
A countertop reverse osmosis system costs more up front but less per gallon. See AquaTru vs ZeroWater and AquaTru vs Brita.
Common questions
Is ZeroWater better than Brita?
On certified claims, the Culligan ZeroWater: it’s certified by IAPMO R&T for fluoride, Total PFAS, lead, chromium-6, mercury, and nitrate. The Brita Elite is the better pick on running cost, filter life, and taste, and it’s certified for lead, mercury, cadmium, and chlorine.
Does Brita remove PFAS?
Brita says its Elite filter reduces PFOA and PFOS, but none of IAPMO R&T, WQA, or NSF International lists that claim, so it isn’t certified. The Culligan ZeroWater is certified for Total PFAS. See our PFAS guide.
Do both remove lead?
Yes. The Brita Elite filter is certified for lead in most Brita pitchers, though not the Everyday OB46, and both ZeroWater pitchers are certified for lead by IAPMO R&T. The standard Brita filter has no lead claim. See our lead guide.
Why does ZeroWater water taste different?
Its ion-exchange filter removes dissolved minerals such as calcium and magnesium, which give tap water much of its taste. Brita’s filter leaves most of them in.
How often do you change each filter?
About every 120 gallons for the Brita Elite, which Brita puts at about six months. Every 20 gallons for the Culligan ZeroWater, its certified capacity, and sooner on hard water; the included meter shows when it’s spent.
