Laboratory Test Results for Clearbrook Bacteriostatic Water Filters
Taste & Odor Reduction
| % of rated service life | Cumulative gallons | Influent ppm | Effluent* ppm | % FAC* reduced |
| 0% | 0 | 2.0 | <0.2 | 90+ |
| 10% | 1,080 | 2.2 | <0.2 | 90+ |
| 50% | 5,000 | 2.0 | <0.2 | 90+ |
| 80% | 8,000 | 2.0 | <0.2 | 90+ |
| 100% | 10,000 | 2.0 | <0.2 | 90+ |
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.

Volatile Organics Reduction
| % of rated service life | Cumulative gallons | Influent concentration | Effluent concentration |
| start | 0 | 0 | <0.10 mg/l |
| 20% | 2,000 | 0.50 mg/l | <0.10 mg/l |
| 40% | 4,000 | 0.50 mg/l | <0.10 mg/l |
| 60% | 6,000 | 0.50 mg/l | <0.10 mg/l |
| 80% | 8,000 | 0.50 mg/l | <0.10 mg/l |
| 100% | 10,000 | 0.50 mg/l | <0.10 mg/l |
| 120% | 12,000 | 0.50 mg/l | <0.10 mg/l |
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.
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.
