How do the reverse osmosis countertop systems work?
A. With reverse osmosis, the water is filtered so fine as to remove the minerals and salts, thereby purifying the water. Pure water is separated from the salty water and stored in the reservoir that sits on the counter. The salts are rejected down the drain of the kitchen sink. The unit attaches to the main sink via a hose to the end of the faucet, and allows use of the main faucet, or one can press the diverter valve and make purified water into the reservoir. In addition to the omosis membrane, it also has a five micron filter, and two carbon filters for excellent removal rates.
