It does work when the other filters could not get rid of chlorine smell. The primary issue for me is that the thread on the filter is different(not as long) as most. For me, this meant I could not fully screw on the shower head, and I have one with separate wand. If it was fully screwed on the filter, the wand would be on the wrong side and cause water flow issue. I ended up having to use the tape to ensure no leak occurred, since i couldn't sully screw on the shower head. If you don't have an auxiliary wand, you should be fine.
