Granular Activated Carbon Water Filtration System
Couldn't load pickup availability
Crystal Quest® Commercial Granular Activated Carbon (GAC) Filters are designed and manufactured for outstanding service. Our filters are the perfect solution to adsorb unfriendly and potentially harmful substances from your water source. GAC filters have applications in a variety of settings including government usages, school campuses, service industries, agriculture, and much more.
In fact, GAC has been known as the miracle media filter of choice by researchers for centuries due to its unique ability to improve taste, odor, and the color of water by removing undesirable contaminants. The EPA has deemed GAC filters to be the recommended method for removing a host of potentially hazardous and possibly carcinogenic chemicals in drinking water.
