An in-home review of several shower filters tested under real world conditions. Tests include before and after total residual chlorine levels using a digital chlorine meter to measure the results. The shower filters are tested for their ability to remove total residual chlorine in an actual residential shower unit. This review puts various manufacturer's claims to the test. Find out what they don't want you to know.

Test Procedure ...
Extech EX800 Digital Chlorine Test Kit
The Gear
All before and after chlorine measurements were taken with the EX800 total residual chlorine test kit shown above according to its operating manual. Baseline measurements for unfiltered shower tap water are an average of three separate tests to ensure accuracy. The three test samples were taken at the beginning, middle and end of the testing cycle. Total residual chlorine levels were measured in parts per million (p.p.m.), which include both free and combined chlorine. The average water temperature during this test was 105˚ Fahrenheit.
The Procedure
Each shower filter was installed per instructions and run for several minutes to allow for "break in". The water temperature for all shower filter test samples fell somewhere in the range of 100˚-105˚F, which is the equivalent of your average warm shower. The eight shower filters were installed, tested and uninstalled one after another. Once the last shower filter was tested, the procedure was repeated for a second time allowing all eight shower filters to be tested again for maximum accuracy. The results of each shower filter's total chlorine reduction is an average of the two tests.
The Data
The result of each chlorine measurement was recorded exactly as it appeared on the digital chlorine meter. This data was recorded in parts per million (p.p.m.) and is accurate within 0.01 p.p.m.
