Reverse Osmosis System

A Reverse Osmosis System from RainSoft Provides Bottle-Quality Water — Without the Bottle

Reverse Osmosis System

With an Ultrefiner II reverse osmosis drinking water system from RainSoft, you can enjoy cleaner, healthier, more refreshing drinking water any time simply by turning on your faucet.  Our reverse osmosis system provides a convenient and effective method of drinking water filtration through the use of three or four (depending upon the model) highly effective filters. First, the water is fed into a pre-filter cartridge that takes out chlorine taste and odor, microscopic particles, and other contaminants. The filtered water is then forced through a spiral-wound, semi-permeable reverse osmosis membrane, where it is filtered on a molecular level and subsequently transferred to a storage tank. Finally, the highly filtered water is polished through the system’s post-filter before being dispensed – fresh and clean – through your dedicated drinking water faucet.

In short, our premium reverse osmosis systems provide multiple lines of defense to purify the drinking and cooking water your family relies on. And not only will the water in your glass taste distinctly better, but so will the food and beverages you prepare with it. Water is the number one ingredient used in your kitchen, and you’ll taste the difference every time you add water from your RainSoft reverse osmosis system.

In addition, a reverse osmosis system from RainSoft is:

  • More economical than buying bottled water
  • More convenient than purchasing and carrying bottled water home or scheduling deliveries
  • Kind to the environment by reducing the number of plastic bottles that end up in landfills
  • Able to effectively remove miniscule and dissolved contaminants and impurities that slip through less sophisticated units

RainSoft is proud to offer premium quality drinking water systems Tested and Certified by the Water Quality Association (WQA), a not-for-profit international association of manufacturers, distributors, and dealers of water treatment systems. This Gold Seal certification confirms that our reverse osmosis systems are tested and found to have met strict standards for the reduction of contaminants as well as rigorous safety, structural integrity, and strength requirements. In sum, a WQA Gold Seal certification provides strong assurance of our products’ quality, durability, and effectiveness.

If you are interested in our under sink water filtration system, please contact a RainSoft dealer near you. We’ve been taking the worry out of water since 1953, and we’ll be happy to provide more information on a reverse osmosis system, as well as our water softener systems, whole house water filtration systems, and air purification systems for your home.
