Bests & Worsts Reviews from Amazon

This product claims to remove 97% of chlorine so I decided to try it. The tests were done with Extech CL200 Chlorine Meter. After installing filter, i let shower run for 7 minutes before taking test. The water coming out of the faucet without filter installed showed .38mg/liter of chlorine @ 87F. With filter installed i had .27mg/liter of chlorine @ 84F, which comes to 29% reduction in chlorine. My drinking water filter showed .01mg/liter of chlorine. This shower filter might do better with cold water (that's probably how it's been tested by manufacturer) but you probably don't want to take cold shower anyway. I'll try to test other shower filters but from what i read its hard to remove chlorine from hot water and some shower filters actually change free chlorine to a less active form(I don't know if its the case with this filter). If you want chlorine free shower, your only option is to install whole house filter.
