Reverse osmosis (RO) filtration systems are rarely used in whole-house applications. Rather, they are installed at a single point of use, most commonly a kitchen sink. If you have installed a sediment filter and UV system but are not satisfied with how your water tastes, an RO system will remove foul odors and flavors that make the water unpleasant. In addition, RO systems remove practically all other contaminants from water. These systems are especially important if your water supply contains lead, arsenic, or other hazardous contaminants that can be bathed in but not consumed.
Reverse osmosis systems remove:
- Herbicides and pesticides
- Most other contaminants
Reverse osmosis systems do not remove:
- Some types of bacteria, viruses, and parasites
