 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).

Chemical Influent Effluent Efficiency EPA MCL
THM (chloroform) 0.57 0.029 95% 0.1
Lead 0.19 0.006 97% 0.025
Fluoride (1) 8.26 0.78 91% 1.4
Nitrate (1) 30.7 8.03 74% 10.0
Barium 10.4 0.56 95% 1.0
Arsenic 0.37 0.007 98% 0.05
Cadmium 0.03 0.004 87% 0.01
Chromium VI 0.15 0.011 93% 0.05
Chromium III 0.163 0.003 98% 0.05
Selenium 0.1 0.006 94% 0.01
Mercury 0.006 0.000* 99+% 0.002
Endrin 0.0008 0.000* 99%+ 0.0002
Lindane 0.011 0.0012 89% 0.004
Methoxychlor 0.32 0.0059 98% 0.1
Toxaphene 0.013 0.000* 99%+ 0.005
2,4-D 0.3 0.02 93% 0.1
Silvex (2,4,5-TP) 0.029 0.004 86% 0.01

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.



 including "Corrected Water" systems

Triple Under Counter System

 One of our dual or triple Redox & Carbon plus Solid Carbon Block point-of-use units will effectively reduce or remove the following contaminants:

 ~algae  ~bacteria  ~parasites  ~mold/fungus  ~bad taste  ~bad odor  ~pesticides (eg. Endrin, Lindane, Methoxychlor, Toxaphene, etc.) ~herbicides (eg. Silvex; 2, 4-D; etc.)  ~fertilizers  ~nitrates  ~detergents  ~PCB's  ~THM's  ~arsenic ~aluminum  ~barium  ~cadmium  ~chlorine  ~chromium ~fluoride ~hydrogen sulfide ~iron  ~lead  ~mercury  ~radon ~selenium ~and many more

We have been in the water purification business for over 40 years.

All components of our water systems are free of BPA.

WARRANTY: Our point-of-use water filtration system housings and hardware have a warranty to be free of defects in materials and manufacture, with repair or replacement for up to one year from date of purchase, and our water cartridges for up to 90 days. (See return and liability policies.)

NOTE: For those on fluoridated city water, our special flow through units for fluoride removal or our reverse osmosis systems will thoroughly eliminate fluoride. All of our drinking water purifiers have replaceable cartridges, and clear installation instructions. We also have whole house systems.
