ultimate drinking water filters purifiers 100% Pure, BEV Quality Drinking Water

PWS® BEV-500 water purifiers utilize a lab grade reverse osmosis / deionization process to completely remove dissolved salts, nitrates, heavy metals, chemical pollutants, pesticides, and disease causing waterborne bacteria and virus (EPA EST. NO. 52531-FL-01).

Our designs have been laboratory tested and certified to conform to currently recognized BEV standards for pH, rH2, and resistivity. PWS® BEV Series appliances offer the ultimate in water purity and bio-compatibility.

All PWS® BEV Series water filters provide complete removal of any & all contaminants found in your drinking water including:

For those who desire alkaline water, a remineralization filter (PWS-pHPlus™) has been developed which will raise the pH of the purified water to ~9.5. The pHPlus™ module provides a superior alternative to expensive alkaline water machines which are not able to remove all dangerous toxins from your drinking water. What good is alkaline water if it contains dangerous chemicals?

home water treatment purification systems and equipment Custom Reverse Osmosis Membrane

Our exceptional reverse osmosis membranes are all wet-tested before installation into one of our systems, and provide consistently high rejection rates, even when installed in real world scenarios. All of our membranes begin with rejection rates greater than 97% (many >98%), and after 3 years are usually still delivering rejection greater than 90%. Compare that to the membranes in many cheap RO systems with membrane performance dropping to 80% in as little as 6-months!

Off-the-shelf membranes used in the majority of RO products simply do not provide the consistency necessary to ensure BEV quality water. Outside of laboratory conditions other membranes seldom meet their stated specifications.

ultimate reverse osmosis drinking water filters purifiers Proprietary Deionization Module

After the reverse osmosis process removes 97% of contaminants, our deionization phase removes greater than 97% of whatever remains. This unique multi-stage module contains a proprietary blend of deionization resins (which capture any contaminants not removed by reverse osmosis) followed by several inches of carbon to polish the water for exceptional taste, ending with two stages engineered to block any backward migration of contaminants into the system.

Other Features Include:

drinking water purification and filtration systems Exclusive 5-year Warranty
