Reverse Osmosis

List Of The Best Reverse Osmosis Water Filter Systems For The Home. Reverse Osmosis Systems are the most thorough water filter systems available for the average home consumer. Reverse Osmosis Systems go beyond the normal carbon water filter system. Many of the RO water filter systems you see here do have one or two phases of carbon water filtration. But in Reverse Osmosis, Water is pushed through a semipermeable membrane leaving most of the impurities behind.

Five-Stage Filtration Removes Contaminants
The Watts RO filters in five stages to ensure that your drinking water is as healthy and clean as possible. Once the system is connected, water passes through a 5-micron sediment filter that traps particulate matter–such as dirt, rust, and silt–that can affect the taste and appearance of your water. Next, a 5-micron carbon block filter reduces chlorine taste and odor, as well as other materials that can give water a bad taste. For the third stage, another 5-micron carbon block filter further reduces chlorine, as well as difficult-to-remove chloramines.

Reverse Osmosis for High-Quality Drinking Water
The system’s fourth stage of filtration is especially important, as it involves the passage of water through the reverse osmosis (RO) membrane. This semi-permeable membrane effectively removes arsenic, lead, perchlorate, chromium, copper, TDS (total dissolved solids), sodium, and a long list of other water contaminants. It also removes parasytic cysts, such as giardia and cryptosporidia.

The fifth stage of filtration utilizes a high quality GAC filter, which works as a final polishing filter when the water leaves the storage tank on its way up to your faucet. The end result is consistently great-tasting water at just pennies per gallon.

The Importance of Drinking Clean Water
Water is critical to proper food digestion, kidney health, brain function, blood health, joint functionality, and more. It’s important to make sure that the water you drink is devoid of contaminants. Thankfully, using a Watts water filtration device will ensure consistent quality for all of your drinking and cooking needs. In fact, when you use Watts’ high-quality certified water treatment devices and filters, your water will be free of chlorine taste and odors, particles, and many other contaminants that can be detrimental to your health.

*Please refer to the Performance Data Sheet for the complete list of claims for which this system is certified.

Not only is the RO filter a healthy choice for you, but it’s also a healthy choice for the environment. This filter helps you minimize the harmful environmental consequences of buying bottled water. Incredibly, if a mere ten percent of North America’s bottled water intake were reduced by switching to home-filtered water in reusable containers, we could eliminate:

  • 133,000 trucks driving an average of 500 miles–saving nearly 12 million gallons of diesel fuel
  • Over 100 million pounds of greenhouse gasses–equal to taking 1,100 cars off the road annually
  • 213 million pounds of PET–equal to 1.5 million barrels of crude oil or improving the PET recycling rate by 10%

Depending upon which Watts water-filtration product you use, you can prevent up to 16,000 half-liter bottles from being deposited in landfills–all in the time it takes to use and replace a single filter.

The Watts Premier Five Stage Reverse Osmosis Water Filtration Device is backed by a three-year limited warranty.
