Operation: First Stage: The PP pre-filter removes rust, sand, clay and floating substances which are bigger than 10um, improving the efficiency of the carbon filter. The average total purified water capacity is 9,000L, and we recommend changing the filter every 3 months. Second Stage: The granular activated carbon filter can remove some organic chemicals, pesticides, floating substances, remnant chloride, unpleasant tastes, odors or colors as well as heavy metal particles. The average total purified water capacity is 12,000L, and we recommend changing the filter every 6 months.Third Stage: The block activated carbon filter can remove some organic chemicals, pesticides, floating substances, remnant chloride, unpleasant tastes, odors or colors as well as heavy metal particles. The average total purified water capacity is 12,000L, and we recommend changing the filter every 9 months.The Fourth Stage The Reverse osmosis (RO) membrane can efficiently remove dissolved salts, heavy metals, bacteria and some organics larger than 0.001um ,and the desalinations rate is more than 98.5%. The average total purified water capacity is 18,000L, and we recommend changing the filter every 12 18 months.Fifth Stage: The small post carbon filter adjusts the water PH value, removing unpleasant tastes, odors and colors, and making the water taste better. The average total purified water capacity is 12,000L, and we recommend changing the filter every 12 months.
