  3. GOES GREEN- 88 Shower Soft Water Filter- 1000
    Goes Green Shower Soft Water Filter
    Goes Green Shower Soft Water Filter - Top Of The Line Shower Filter. Uses 300 grams of pure KDF. Easy to install. Superior performance over carbon for chlorine removal in showers. Prevents bacterial growth. Good for one year or 30,000 gallons, which ever comes first. Help's enhance hair's pH balance, softens hair and skin. Helps preserve hair color. CHLORINE is an inorganic substance that chemically bonds to the protein in your hair and skin, destroying its natural ecological balance. Chlorine can leave your hair dry and brittle and make your skin flaky and itchy. As much as 50% of the chlorine taken into the body comes from skin absorption and inhalation. The other 50% is drinking water. KDF is far superior at removing chlorine than carbon in the shower. While carbon is great for drinking water filters, it is not great with hot water such as a shower. In hot water carbon can slough off some of the chemicals that it may have absorbed. That is why the package on the faucet & pitcher drinking water filters tell you to not use hot water in them. For hot water in the shower, KDF is "hands down" the best filtration media available. Installs easily between existing shower head and pipe. Shower head not included. Standard 1/2" NPT pipe thread size. Only 4 1/2" long by 2 1/2" diameter. With Convenient Replacable Cartridge. Order 2 or more and save even more!
