Reverse Osmosis vs. Whole-House Filtration
By North DFW Water Editorial Team · Published 2025-01-01
Point-of-use RO and whole-house filtration solve different problems. Here's how to think about the difference.
Where each is installed
Whole-house filtration is installed at the main water line and treats water for the entire home. Reverse osmosis is usually installed at a single point of use — most commonly under the kitchen sink — for drinking and cooking water.
What each is designed for
Whole-house filtration commonly targets chlorine, sediment, taste, and odor. RO membranes are designed to reduce a wide range of dissolved substances in drinking water.
When both make sense
Many households use both: whole-house filtration for showers and appliances, and RO for drinking water at the kitchen sink.
