USE THE FILTER THAT LETS YOU GET MORE OUT OF YOUR WATER


Testing performed by an independent, EPA Certified Laboratory and does not have any affiliation with Zero Technologies, LLC or Brita.

Challenge Water Preparation:
The VOC challenge water was prepared by adding 400 µL of the Restek standard catalog # 30431 (concentration 2,000 µg/mL) to 40 Liters of water to get a concentration of 20 µg/L for each VOC. The challenge water was passed through each filter, side by side, at a rate of 10 liters per day, 45 minutes on/45 minutes off, and a filtered water sample was taken from each filter after 40 liters and tested for VOCs along with the challenge water sample using the EPA method 524.2.

The Metals challenge water was prepared by adding the appropriate amount of reagent standard to 4 Liters of water to get a concentration of 3 to 10 times the acceptable EPA safe limit for each Metal. The challenge water was passed through each filter, side by side, at a rate of 1 liter, 45 minutes on/45 minutes off, and a filtered water sample was taken from each filter after 4 liters and tested for each metal along with the challenge water using the EPA methods 200.9; 208.2 for Barium; and 245.1 for Mercury.

The Pesticides challenge water was prepared by adding 2 mL of the CPI standard catalog # Z-132143-05 (concentration 500 µg/mL) to 20 Liters of water to get a concentration of 50 µg/L for each compound. The challenge water was passed through each filter, side by side, at a rate of 10 liters per day, 45 minutes on/45 minutes off, a filtered water aliquot was taken from each filter after 20 liters and tested for Pesticides along with the challenge water sample using the EPA method 508.

The Semivolatile challenge water was prepared by adding 1 mL of the Restek standard catalog # 31899 (concentration 1,000 µg/mL) to 4 Liters of water to get a concentration of 50 µg/L for each Semivolatile. The challenge water was passed through each filter, side by side, at a rate of 10 liters per day, 45 minutes on/45 minutes off, a filtered water aliquot was taken from each filter after 20 liters and tested for Semivolatiles along with the challenge water sample using the EPA method 525.

The Inorganic-Non-Metals- Parameters challenge water was prepared by adding the appropriate amount of reagent standard to 4 Liters of water to get a concentration of 3 to 10 times the acceptable EPA safe limit for each Parameter. The challenge water was passed through each filter, side by side, at a rate of 1 liter, 45 minutes on/45 minutes off, a filtered water sample was taken from each filter after 4 liters and tested for each anion along with the challenge water using the respective EPA method, or Standard Method for the Examination of Water.

Summary:
The compounds tested are compounds listed by EPA as Primary and Secondary drinking water contaminants. The compounds tested are also listed by the NSF/ANSI Standard 53 and Standard 42 with established procedures for filter manufactures reduction claims. The procedure used in this comparison study were based on the NSF/ANSI standards 42 and 53, 2012 editions. The methods of analysis used in this study are EPA approved methods for drinking water for which Envirotek Laboratory is currently certified and has the capabilities to perform the test. The EPA primary drinking water contaminants not tested were those for which Envirotek Laboratories does not have the equipment or capabilities to perform the test.
