Reverse Osmosis vs Whole-House Filtration: Key Differences
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.
How reverse osmosis works (and what it removes)
An RO system forces water through a membrane that allows water molecules to pass while rejecting many dissolved substances. Depending on the system design and pre-treatment, RO is commonly used to reduce contaminants like dissolved salts and some heavy m ... Read more »
