There are a lot of misleading claims about water filters. Many filters are marketed with general statements like “improves taste and odor”. But filter manufacturers don’t mention the specific amount of pesticides or chloramines removed, for example.
I’ve spent quite a bit of time researching how to filter drinking water effectively. Originally, I was interested in filtering the rainwater that falls on my roof. But I had to put that project on the back burner for now. During my research I noticed that there is little unbiased information available on water filters and filtration techniques.
