How are the ZeroWater filters tested?
Test results as performed by 3rd party laboratory is based on NSF/ANSI testing protocol of pour through devices for contaminants listed under the National Primary Drinking Water Standards.
Contaminants were tested at the average Influent Challenge Concentration levels as established under testing protocols by contaminant type. Results shown are based on a 40 gallon filtration, double the rated usage to ensure consumer safety.
These results are calculated from an average of two pH's (6.5pH and 8.5pH) * Indicates NSF Certified Contaminant reduction percentages for ZeroWater. These results are calculated from an average of two pH's (6.5pH and 8.5pH) Testing performed Quality Filter Testing Laboratory, LLC located in Wilmington, DE. Quality Filter Testing Laboratory, LLC is an independent ISO 17025 laboratory certified by WQA and IAPMO to test water filters as per NSF/ANSI Std 42, 53, 58, 401, 473, P231.
