Is Reverse Osmosis Worth It?

For some homes it's a game-changer; for others it's unnecessary. Here's how to tell which camp you fall into.

What RO Does Well

Reverse osmosis reduces a broad range of dissolved contaminants at a dedicated drinking tap — things that whole house filtration and softening don't address. If the water your family drinks and cooks with is your priority, RO is the most thorough option for that one tap.

What RO Doesn't Do

RO treats water at one tap, not the whole home. It doesn't soften water or reduce chlorine at your showers. If your concerns are whole-home — scale, chlorine at every faucet — you'd want a whole house filter or softener instead of (or alongside) RO.

How to Decide

RO is worth it when drinking-water quality is your goal. It's not worth it if you're really after whole-home improvements. A free test helps you see whether your water has the dissolved contaminants RO is designed to address — and whether it's the right investment for your home.

Frequently Asked Questions

For homeowners concerned about drinking-water quality, RO is often worth it — it reduces a broad range of dissolved contaminants at a dedicated tap. If your main concern is whole-home taste or hardness, a whole house filter or softener may be the better first step.
