1812 100 GPD RO Membrane – Lateral Filtration Element

n

The 1812 100 GPD RO Membrane is a reliable lateral reverse-osmosis element for homes and small commercial systems. Additionally, this membrane efficiently purifies low-salinity water from municipal sources, boreholes, or tap water, producing up to 380 liters per day. Its lateral-flow design allows flexible installation in standard 1812 RO housings, ensuring consistent water quality for drinking, cooking, and light commercial applications.
