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

PWS™ BEV-300 water purifiers utilize a patented reverse osmosis and 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). All components are NSF Certified and/or FDA approved materials.

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.

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?

ultimate water filters water purifiers Twin Carbon Pre-filters

Twin, unidirectional granular activated carbon pre-filters using clean, steam washed, bituminous grade carbon. Flow is length-wise, not radial, for maximum contact time and organic adsorption.

Other manufacturers include only a single carbon pre-filter, often using less efficient coconut shell carbon which can contain metals, arsenic, and phosphorous.

“I want to thank you for developing the BEV-300. I began searching for an exceptional purification system after my 2-year-old son was diagnosed with autism. Many autistic kids are extremely sensitive to toxins in our air, food and water... even trace amounts.

I needed a system that would filter out everything - from sediment and heavy metals to chlorine and fluoride (two known neurotoxins). I wanted to make sure the only thing I was putting in my son's body was pure water. Your system answered that call. In addition to meeting all my requirements the BEV-300 fit nicely into my sink cabinet and was easy to install. The real bonus: its the best tasting water I've ever had!”
— Daniel Pitt, Seattle, WA

home water treatment purification systems and equipment Custom Rolled Reverse Osmosis Membrane

Our exceptional reverse osmosis membrane provides consistently high rejection rates, even when installed in real world scenarios.

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

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 Lifetime Warranty

The best warranty in the industry! We are so confident in the quality of materials and components in these systems we provide a lifetime warranty (exclusive of module changes and abuse).

Our systems are designed to last decades, not months or years. Should any part ever fail, we will repair or replace it free of charge.

bottled water, delivered water Save Big vs. Bottled Water

With a cost of ~12¢ per gallon*, the PWS™ BEV-300 systems pay for themselves very quickly when compared to bottled / delivered water which averages ~79¢/gallon. If you use 3 gallons per day, you'll save over $500 per year! Plus, you'll have confidence you are providing your family the ultimate in pure drinking water regardless of whatever new, toxic chemical is found next in our water supplies.
