There is more in your home’s water than just H2O. Sediment, arsenic, lead, chlorine, herbicides and pesticides are just a few examples of what you may be drinking from your faucet.
Reverse osmosis removes contaminants by forcing unfiltered water through semipermeable membranes, also known as RO membranes. The small pores of the membrane block contaminants, leaving clean water. There are often filters in RO systems that also work to remove sediment and other contaminants that may contribute to bad tasting water.
