A Culligan® Reverse Osmosis Drinking Water System provides great-tasting water every time. We use the most advanced technology available, which is able to remove impurities and contaminants far more effectively than filter pitchers and faucet filter attachments.

Culligan RO systems use a process called reverse osmosis (RO)- A high-threshold filtration process that pushes water through a semipermeable membrane. The membrane allows water to pass through, but not impurities or contaminants, which are then flushed down the drain. This means contamination is at an absolute minimum relative to other water solutions, and subsequently so are the health risks.

Never worry about chlorine, lead, mercury, or nitrates that are sometimes found in tap water, not to mention foul tastes and odors, when you rent or buy a Culligan® Reverse Osmosis Drinking Water System!

Culligan® Reverse Osmosis Systems are easy to use and maintain – simply change out the cartridges annually, or make a service appointment with your local Culligan Man™. Our compact units fit easily under most sinks, and can often be plumbed through your fridge, sink and even your ice maker.

So if you’re looking for a solution that:

  • Provides a continuous supply of high-quality drinking water at your kitchen sink
  • Removes dirt, silt, clay and other sediments
  • Removes unpleasant tastes, including sour, metallic and soapy tastes
  • Removes unpleasant odors, including chlorine and “rotten-egg” smells
  • Provides Water that is 99.9% pure, ridding it of more harmful contaminants than any other water purification system

Then Reverse Osmosis water is the route for you.
