Performance Results

Our 5-stage filters underwent rigorous testing, demonstrating significant reductions in the forever chemicals PFOA and PFOS, lead, chromium, and mercury. Our advanced 5-stage filtration system consistenly surpasses industry benchmarks and establishes a new standard for water quality.

IAPMO Independently Certified

ZeroWater’s 5 Stage Ion Exchange Filter is IAPMO certified to reduce PFOA/PFOS, lead, chlorine, chromium and mercury.

Testing Methodology

Water samples were prepared with inorganic non-metal and metal concentrations in accordance with NSF/ANSI standards. For inorganic non-metals and metals tested outside of the NSF/ANSI standard, a concentration of 10 times the EPA's drinking water limit was used for each compound. The water was then passed through each filter, side by side, at a rate of 1 liter every 90 minutes. After the prepared water was exhausted, a water sample was taken and analyzed to produce the results listed below.

ZeroWater's 5-stage filter with a rated capacity of 15 Gallons and Brita's Standard Filter OB03 with a rated capacity of 20 Gallons were tested in accordance with the products' recommended daily usage of 2 gallons of filtration per day. Results shown are based on an averaged calculation of each filter's test results of drinking water at a pH level of 6.5 and pH level of 8.5. Brita is a trademark of Brita LP.
