If your source water is highly contaminated, and your water treatment requirements require high quality water with a minimum of chemical manipulation then a Reverse Osmosis filtering system may be just what you need for clean, healthy drinking water, in some of the harshest of conditions.

Reverse Osmosis is a process for removing dissolved mineral salts, organic molecules and many other impurities by forcing water under pressure to pass through a multi process filtration system with semi-permeable membranes.

Since Reverse Osmosis does not occur naturally, it must be created by applying pressure to the water in order to force it through the membrane to remove the solids from the water. With pressures from 200 to 400 psig in most applications or even up to 1,200 psig for sea water desalination and high solids conditions. Click here to learn more about how Reverse Osmosis Filtration works

We also offer below counter, whole house (featured below) and high capacity commercial use Reverse Osmosis water filters and RO water purification and filtering systems (also featured below).

Our Purest Filters brand of whole house RO water treatment systems treat from 150 gallons per day to over 800 gallons per day for well water, brackish, salt water, and highly contaminated water treatment - we have your Reverse Osmosis water filtering solution.

The following Purest Filters RO water treatment systems are Made in the USA

Any of our Reverse Osmosis water treatment systems can have an Ultraviolet / UV Water Sanitizer added to the water filtering system, for the ultimate assurance of clean and healthy sanitized water. The addition of UV disinfection assures the removal of 99.99% of all micro-organisms (viruses, bacteria, mold, etc.) from your drinking water ( Click HERE to view list of Microorganisms disinfected by UV ).

For any Reverse Osmosis water filter system that does not include an integrated UV water purifier, you can always add any of our 170+ UV Water Purifiers currently offered as an additional water treatment component for the added assurance of the healthiest of clean, pure and sanitized water in your home, office, or business.
