The Watts RO filters in five stages to ensure that your drinking water is as healthy and clean as possible. Once the system is connected, water passes through a 5-micron sediment filter that traps particulate matter–such as dirt, rust, and silt–that can affect the taste and appearance of your water. Next, a 5-micron carbon block filter reduces chlorine taste and odor, as well as other materials that can give water a bad taste. For the third stage, another 5-micron carbon block filter further reduces chlorine, as well as difficult-to-remove chloramines.
Reverse Osmosis for High-Quality Drinking Water
The system’s fourth stage of filtration is especially important, as it involves the passage of water through the reverse osmosis (RO) membrane. This semi-permeable membrane effectively removes arsenic, lead, perchlorate, chromium, copper, TDS (total dissolved solids), sodium, and a long list of other water contaminants. It also removes parasytic cysts, such as giardia and cryptosporidia.
