The Trio

We know that filters are not a "one size fits all." That's why we developed three different cartridges. 1) PURIST filter for the purist, 2) ARTESIAN filter for the idealist, and 3) ALKALINE filter for the enthusiast.

What is 4D- Purification?

4D Purification™ combines traditional filtration with a time-dependent variable. In a conventional filtration system, water gets treated 3-dimensionally as it travels through the filter's X, Y, Z planes with no significant time-dependent variable. In the 4D Purification™ system, the UVC treatment system adds significant time-dependent purification before the water gets further purified 3-dimensionally in the filter cartridge system.

Purification, Filtration & Beyond!

We value the world we live in. That's why at WAATR, our mission is to go beyond purification by providing knowledge and information on the contaminants lurking in your drinking water. We do this by studying your used PUREMAX 4D filter cartridges. Simply ship your used filters to our facility and our scientists will analyze them carefully and provide you with a detailed lab report. This information will assist you in taking the necessary preventive measures to limit exposure to harmful contaminants if they are present in your source water.


UV-C Purification

Over the years, several scientific studies show the effectiveness of UV light in disinfecting surfaces. Most recently, scientists discovered a particular portion of this UV spectrum, UVC, having maximum germicidal efficacy. With the very meager power of this UVC, one could disinfect a surface more effectively than traditional high-power UV systems. Our products use this particular region of the UV spectrum to achieve the maximum neutralizing effect against a wide variety of bacteria, viruses, and pathogens.

Charcoal + Ion-Exchange Resin Filtration

PUREMAX 4D filter cartridge system consists of a proprietary blend of coconut charcoal and ion-exchange resin. Coconut charcoal is a highly porous organic material designed to capture organic molecules and chlorine effectively. Ion-exchange resin is a spherical porous bead resin material designed to exchange ions (inorganics) in the water for other Ions fixed in the resin. This process is very effective in reducing the hardness of the water.
