I have a dry skin and especially during the winter my skin on my face and hands gets red and cracks looking awful. I noticed that it happens after I take a shower – I in south of the U.K. in hard water area. I tried creams, moisturisers etc but nothing helped. Two weeks after installing this filter, the skin on my who body looks normal in November! I do t know how it works, but this saves me in a lot of ways. If you have a dry skin, order it now! You want regret it and you will save money on creams etc!
