I purchased 2 of these showerheads (one for my husband and I and one for the guest bathroom)because I am not supposed to be exposed to cholorine for health reasons. There are other impurities that I didn't want on my body when showering, too. When you buy something with a filter, it seems that the water flow just isn't there, however, I am very happy with the water flow. I would recommend this showerhead.
