Under-sink water filtration installed by CMA Plumbing

Purified water for drinking and cooking

A reverse osmosis (RO) system pushes water through a very fine membrane plus several filters to remove a wide range of dissolved solids, taste and odor. It sits under the kitchen sink with its own small faucet and storage tank, or a tankless RO unit.

RO is designed for drinking and cooking water, not the whole house. It pairs perfectly with a softener or whole-house filter.

Reverse Osmosis FAQ

What does reverse osmosis remove?

RO reduces a wide range of dissolved solids, plus taste and odor. Exact performance depends on the system’s certification. We’ll show you the specs.

Does RO waste water?

RO systems send some water to the drain to rinse the membrane. Newer systems are much more efficient than older ones.

How often are filters changed?

Pre-filters typically every 6–12 months and membranes every few years, depending on use and water quality.

Can RO connect to my fridge?

Yes. We can run a line to your refrigerator and ice maker.
