The H2 ZERO whole house filtration system uses a single-tank design with High Activity Carbon (HAC) to effectively remove contaminants like free chlorine from water throughout the entire home, producing clean water with no unpleasant taste or odor. The system is fully self-contained and requires no electricity, backwashing, or maintenance, making it highly efficient with zero water waste. The HAC media meets NSF/ANSI Standard 61 and works across various pH levels to deliver highly polished, filtered water for the whole house.
