Even when treated by an approved municipal water system, the goodness of water is often marred by minerals, organic matter or chlorine.  Reverse Osmosis is a filtration process used for water. It works by using pressure to force a solution through a membrane, retaining the solute (dissolved solids)on and allowing the pure solvent (water) to pass to the other side. The membranes used for reverse osmosis have a dense barrier designed to allow only water to pass through while preventing the passage of solutes (such as salt ions). This process requires that a high pressure be exerted on the high concentration side of the membrane.

Features For Quality Drinking Water:
Designed for maximum water cleaning efficiency with no operating costs except for periodic replacement of disposable filters
Efficient on water pressure as low as 30 psi
Non-electric operation
Up to 33% more tank pressure for increase flow and volume
Fills holding tank up to 5 times faster than other systems
Membrane technology consistently reduces up to 99% of total dissolved solids (TDS)
Includes a long-reach dispensing spigot with air gap
Completely pre-tested with a 25-year limited warranty

Water Contaminant Reduction:
The H3500 reverse osmosis water softener also reduces contaminants found in a household's water supply such as:
Arsenic (Pentavalent) <=50 ppb, Barium, Cadmium, Cyst, Fluoride, Chromium (Hexavalent), Lead, TDS, Chromium (Trivalent), Nitrate/Nitrite, Radium 226/228and Selenium
