How are the ZeroWater filters tested?
Test results based on NSF/ANSI testing standards of pour through devices as performed by Quality Filter Testing Laboratory, LLC, located in Williamstown, New Jersey, an independent ISO 17025 laboratory recognized by IAPMO.
ZeroWater’s 5-stage filter with a rated capacity of 75 litres and Brita’s Maxtra Filter with a rated capacity of 100 litres were tested in accordance with the products’ recommended daily usage of 7.5 litres 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.
