    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! Learn More

    TDS Meter - Tester. The Only Way To Know If Your Reverse Osmosis RO Membrane Is Performing Correctly - Tests for TDS - Total Dissolved Solids. A Must For All RO System Owners. Compare Incoming Feed Water To Treated Water - Replace Membrane If Less Than 80% of TDS Is Being Removed - The lower the TDS level in the water, the more efficiently your body's cells actually get hydrated by the water that you drink. The higher the TDS levels in the water, the greater the probability of harmful contaminants that can pose health risks or hinder the absorption of water molecules on the cellular level. Simple to use for Reverse Osmosis membrane monitoring. We really like this tester and think that anyone who wants to know about the quality of their water should have one of these TDS Meter Testers to monitor their RO membrane. Learn More
