Reverse Osmosis Water Purification

How the RainSoft Reverse Osmosis Water Purification System Works

Reverse Osmosis Water Purification

The Ultrefiner II is RainSoft’s premier home water purification system. A reverse osmosis membrane, coupled with multiple carbon block filter cartridges, produces drinking water that is effectively free of chlorine taste and odor, lead, chromium, copper, and other volatile organic compounds (VOCs). With an Ultrefiner II, your family will have 24/7 access to better than bottle-quality water right at the kitchen faucet. Your drinking water will taste better, smell better, and be untainted by impurities, visible or otherwise. Virtually anything you use tap water for will be improved, be it brewing coffee or tea, cooking pasta, or just keeping the kids properly hydrated on a hot summer’s day. Even your ice cubes will taste, smell, and look distinctively better thanks to the Ultrefiner II’s advanced reverse osmosis technology. Pitcher water filters, faucet-mounted water filters – they are no substitute for the Ultrefiner II from RainSoft.

In five steps, the Ultrefiner II will take your family’s drinking water to an entirely new level:

  • Step 1 – Water is introduced into the system.
  • Step 2 – A pre-filter cartridge reduces particulate matter and chlorine taste and odor.
  • Step 3 – A spiral-wound, semi-permeable reverse osmosis membrane strips the water of impurities at the molecular level.
  • Step 4 – The water enters a storage tank.
  • Step 5 – When needed, the water will pass through a post-filter cartridge before it is dispensed at the tap.

This premium drinking water system from RainSoft thus provides multiple lines of defense that work in concert to produce clean, great-tasting drinking water the entire family can enjoy. It is the most effective reverse osmosis drinking water system available in North America, and it can fit entirely under your kitchen sink!
