What Does ZeroWater Remove?
Below are the performance results of ZeroWater’s 5-stage filter vs. a conventional filter for inorganic chemicals as listed under the EPA’s national primary drinking water regulations and contaminants listed under the EPA’s secondary drinking water standards. Results shown are based on a 150 litre filtration, double the rated usage to ensure consumer safety.

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 150 litre 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.
