I live in a country where the water is heavily chlorinated and has a lot of calcium, what you would call hard water, it's not good for your skin, hair or shower walls. I was visiting my sister in the USA and she had this filter on her shower, my hair was no longer brittle and dull and my skin problems such as Keratosis Pilaris, eczema and dryness were greatly improved.

I can not say enough about this product. I ordered it and installed it my shower at home, it fit well and works wonderfully. Everybody here has crunchy hair except me, and I am not constantly fighting the hard calcium deposits on my shower walls anymore. thank you.
