DESCRIPTION |
Product description:
This 7-stage RO water purifier is designed to produce ultra-pure drinking water for home use, featuring a precise filtration process that removes up to 99% of impurities. The first stage PP cotton traps sediment and rust, the second and third stages (GAC and CTO) remove chlorine, pesticides, and organic odors, the fourth stage RO membrane filters out heavy metals and dissolved solids, and the fifth to seventh stages (coconut shell activated carbon and mineralization filters) optimize taste and add minerals. The system includes a 3.2G pressure tank, 75G booster pump, 300cc waste water ratio, and all necessary installation accessories (5m PE tube, 2-way faucet, filter wrench, etc.). The main unit is compact (360*215*445mm) and lightweight (6.5kg net), making it easy to install under the sink.
Advantages:
Ultra-pure water production with 99% impurity removal; coconut shell activated carbon provides better adsorption and fresher taste; mineralization function adds essential minerals for healthier drinking; 3.2G pressure tank reduces waiting time; easy-to-maintain filter elements with manual flushing; compatible with 110/220V voltage, suitable for global use.
