Reverse Osmosis Drinking-Water Systems for Twin Cities Homes

Water passes through pre-filters and a semi-permeable membrane designed to reduce many dissolved substances. What a specific system reduces depends on its design and documented performance.

Common
questions
Is RO water the same as distilled water?
No. They are different processes. RO uses a membrane under pressure; distillation boils and condenses water.
Can RO connect to my fridge?
Often, yes, depending on distance, tubing route, and the system. It's worth discussing during planning.
