Reverse osmosis
Reverse Osmosis Drinking Water Systems
A reverse osmosis (RO) system sits under your kitchen sink and gives you a dedicated faucet for drinking and cooking water.
How it works
Water is pushed through a very fine membrane plus pre- and post-filters, then stored in a small tank for the drinking faucet.
Pairs with whole-home systems
Many homeowners combine an RO system at the kitchen with whole-home filtration or softening for the rest of the house.
Common questions
Where is it installed?
Usually under the kitchen sink, with its own faucet.
Can I add it to a whole-home system?
Yes. RO works well alongside whole-home filtration or a softener.
