 NSF Standard 53

 Test Protocol

 Performed by Independent Laboratory

 

Our combination of Eagle Redox Alloy 9500, ERA-6500 and Granular Activated Carbon has been tested according to the NSF Standard 53 protocol for removal of common contaminants from water.

All concentrations are measured in milligrams per liter (mg/l).

20,000 gallons of city water, spiked with high levels of specific contaminants, were run through an ERA-9500 & ERA-6500/GAC cartridge. The efficiency shown below was measured AFTER 20,000 gallons had passed through the cartridge (when new, removal is 99+%). Most other non-standard tests show results after only one pass of contaminated water, which does not indicate how the filter will perform towards the end of its life. To pass the NSF-53 protocol, the effluent must be under the EPA Maximum Contaminant Level (MCL) throughout the test.

A separate test was run on another ERA-9500/ERA-6500/GAC cartridge to determine chlorine removal capacity. The challenge solution contained 3 mg/l chlorine (most cities use less than 1 mg/l). 2 mg/l lead was also added. At 20,000 gallons, both were being removed 99.9+%. The test was terminated at 28,400 gallons when the chlorine removal rate hit 90%. The lead removal was still 97.6%.

* - Below detectable limit.

(1) - While this test shows a reduction in these contaminants, ERA-9500/ERA-6500 is inconsistent in its removal in certain water conditions. We offer special nitrate and fluoride filters, or reverse osmosis, if removal is needed.

Notice: Consumer is responsible for following any state and/or local regulations and plumbing codes pertinent to the purchase, installation and operation of our products.
California Residents: The state of California requires water treatment devices claiming health claims be tested and certified by them - our units are not. Therefore, only aesthetic claims can be made on units shipping to California addresses.
