AQUATICLIFE Twist-in 4-Stage Reverse Osmosis Water Filtration Deionization System, RO/DI Filter Unit 75 GPD

75 GALLONS OF DEIONIZED WATER PER DAY – AquaticLife 4-stage reverse osmosis deionization system reduces salt, calcium, and other metallic ions from water leaving you with clean, clear water for residential use. REDUCES TDS TO ZERO – The RO Membrane Filter 75 GPD effectively removes up to 98 percent of the Total Dissolved Solids (TDS) in water. The remaining TDS is removed by the Resin. EFFECTIVE SEDIMENT REMOVAL – The 5-micron Sediment filter captures and reduces unwanted particulate material such as sand, silt, and rust from water which affect the taste and appearance of your water. CARBON FILTER REDUCES CHLORINE – The second stage of your reverse osmosis water filter is a Carbon Block filter. The 5-micron activated carbon filter reduces chlorine and conditions the water. COLOR-CHANGING DEIONIZATION – The mixed-bed deionization resin is necessary to reduce TDS to zero in the final stage of an RO/DI system. It uses Cations and Anions beads to remove TDS from water.
