Reverse osmosis is one of the most cost effective and efficient ways to remove the majority of all contaminants from your water. Ideal H2O® Catalytic Reverse Osmosis Water Filtration Systems produce up to 200 gallons per day of ultra-pure, low parts per million (PPM) water. These 3 Stage RO systems remove up to 98% of chlorine, 80% of chloramine, and 90% of sediment, silt, and rust. The Ideal H2O® Catalytic RO Systems include a high quality poly spun sediment pre-filter and an advanced catalytic carbon pre-filter. The advanced catalytic carbon pre-filter has 400% more capacity for chlorine and chloramine reduction than standard GAC filters. Ideal H2O® RO Systems come with a 1:1 clean water to waste water ratio. This drastically reduces waste water by 50% over other systems in the market. Includes incoming PSI gauge.
