Two water treatment units were evaluated for taste &
odor reduction claims by the procedures described in National Sanitation Foundation
Standards, number 42, Aesthetic Effects. Chlorine was determined by method 330.5, Methods
of Chemical Analysis of Water and Waste, USEPA Environmental Monitoring and Support
Laboratory, Cincinnati. The results of these tests are presented above. The concentration
of free available chlorine at the effluent was radically lower than the influent at every
test point. The performance of the units far exceeds the standards as specified in NSF
Standards, number 42.

The above test results were performed by the University of
Alabama, Department of Chemistry. Influent concentrations were set at 500 ppb (parts per
billion), over the suggested NSF Standard 53 level of 450 ppb, but within the +/-
20% range of chloroform.

The above test results were conducted on three ordinary
carbon filters and three Clearbrook bacteriostatic filters identified as EPA reg.
#51160-1. The test was conducted according to the following protocols: National Sanitation
Foundation, Std. #42 & 53 and Federal Register, Vol. 41, #152, 8/5/76. The tests shown
above were conducted in an independent EPA certified laboratory and demonstrate that the
bacteriostatic units designated Clearbrook filter #1, #2, #3 are indeed bacteriostatic and
dramatically reduce the level of bacteria contained within the unit.
It is a fact that municpally treated water can, by law,
contain allegedly harmless bacteria. In ordinary water filters, the carbon bed containing
trapped organic compound becomes a growth medium for bacteria. When ordinary carbon
filters are not in use, such as overnight or vacations, a potential buildup of the
bacteria trapped within the bed exists. After some time, the filter bed can contain
millions of bacteria.
Clearbrook filters contain a specially formulated media
that inhibits the growth or regrowth of bacteria within the filter bed. This special
formula makes the Clearbrook bacteriostatic water filter a complete water treatment system
that clarifies, deodorizes and filters all in one easy step.
