RO is Unique blend of form & Function. Result of years of result, it is specially designed to RO the taste of water due to high concentration of Total Dissolved Solid hardness, heavy metal contaminants like Arsenic, Lead and Mercury. The purification procesess used by most water purifiers do not remove these impurities. thus, the water they porovide may be microbiological safe but may not be chemically portable depending on input water quality.Product DetailsSeven Stage Purification Process Stage 1 - Pre Filter Sediment pre filter 5 micron made of polypropylene spun fiber removes suspended impurities in water like sand, dirt, rust, fiber etc. Stage 2 - Pre Carbon Filter Remove chlorine from raw/tap water to improve quality adn to protect membrane.Stage 3 - Sediment Filter The filter uses 1 micron polyprophyline filter to remove sediment to improve quality of water and protect membrane.Stage 4 - RO Membrane Semi purified water is passed through world renowned reverse osmosis membrane with 0.0001 micron pores. Dissolved salts, heavy metals and impurities reduced by 90% and higher.Stage 5 - U.V. Lamp U.V. lamp radiation can deactivate microbiological contamination.Stage 6 - Mineral Cartridge For pH control, gives mineral supply, and make great taste of water.Stage 7 - UF Membrane Prevents smallest bacteria and micro impurities present in water.
