How the Aqua Flo Tankless RO System Works
This system uses reverse osmosis to reduce dissolved solids, chlorine, taste, odor, and other contaminants from your water supply. Incoming water passes through pre-filters before reaching the high-efficiency RO membrane, where impurities are rejected and flushed to drain while purified water is delivered on demand.
Unlike traditional RO systems, there is no storage tank, water is produced as needed, making maintenance and filter health especially important.
