Reverse Osmosis vs Whole-House Filtration

Choosing between reverse osmosis and a whole-house filtration system often comes down to one question: What problem are you trying to solve? Both approaches can make household water taste better and reduce certain contaminants, but they differ in what they remove, where they work, and how they affect plumbing and long-term system costs.

Reverse osmosis (RO) uses a semi-permeable membrane and water pressure to separate dissolved impurities from water. Whole-house filtration typically uses one or more filter stages (such as sediment, carbon, or specialty media) to treat the water as it flows into your home.
