RO reverse osmosis technology which filters the highest accuracy (accuracy of 0.0001 micron filter) Central Water Purifier, one hundred thousandth central water purifier home due to the reverse osmosis membrane pore diameter of a human hair, allowing only water molecules and dissolved oxygen by Family Central Water Purifier, all impurities contained in water, such as pesticides, bacteria, viruses, heavy metals and other harmful substances are retained almost entirely excluded. In addition there are many other reverse osmosis filter technology: Nanofiltration (filtration accuracy between 0.001-0.0001 m) ultrafiltration membrane (filtration precision is between 0.1 to 0.01 microns), fine filter (filtration accuracy of 0.1 m or less, e.g. ceramic filter, PP cotton filter, etc.). PP cotton water purifier can effectively filter the water rust, sand, colloids and all impurities greater than 5 microns in diameter; granular activated carbon filter has a strong adsorption force. Can effectively adsorb chlorine, odor, color, pesticides and other chemicals; precision activated carbon filter can effectively remove bacteria, toxins, heavy metals.
