CHEMICAL FREE (Air Injection) Iron Filters

For reduction of Clear-Water (Ferrous) Iron in Water

Do you see a clear glass of water, or water in a bath tub, turn orange in colour if you leave it standing for some time? If yes, you likely have elevated levels of “clear water iron” in your water.

Clear Water Iron (or Ferrous Iron) occurs naturally in many well waters. In concentrations over 0.3 mg/L (PPM) it causes reddish-brown deposits (stains) on bathtubs , laundry, dishes, utensils, glassware and appliances like dishwashers, washing machines etc. It can also cause deposits in pipes, pressure tanks & water heaters reducing the available water flow and pressure. It affects the flavour and colour of food and water. It may react with tannins in coffee, tea and some alcoholic beverages to produce a black sludge, which affects both taste and appearance.

Rainfresh CAFE Chemical-free Iron Filter removes Iron from all the water in the house including bathrooms, kitchen, laundry and even outside taps. Based on the technology of oxidation and filtration, Rainfresh CAFE filter converts dissolved iron (ferrous iron) in the water to a filterable rust particle (ferric iron), which it then filters out to give you clear, iron-free water.  

After every few days, the unit automatically cleans itself (Backwashing) and dumps the trapped iron and other particles down the drain. A big advantage that the CAFE Iron filter has over other types of iron filters is that the it does not need any salt or chemicals to backwash - just water!
