The ULP1812-50 Reverse Osmosis Membrane is a high-efficiency, ultra-low-pressure RO element engineered for residential water purification systems that demand reliable performance at reduced operating pressure. Manufactured using advanced thin-film composite (TFC) membrane technology, this membrane effectively removes dissolved salts, total dissolved solids (TDS), heavy metals, and other contaminants commonly found in municipal and well water supplies.
With a 50-gallons-per-day (GPD) nominal production rate, ULP1812-50 is ideal for under-sink and point-of-use reverse osmosis systems where consistent drinking water quality is essential. Its ultra-low-pressure design allows the membrane to operate efficiently even in systems with lower incoming water pressure, helping reduce pump usage, lower energy consumption, and extend the life of system components.
Designed in the industry-standard 1812 membrane format, the ULP1812-50 offers broad compatibility with most residential RO housings, making installation and replacement simple. High salt rejection ensures improved taste and clarity, while durable construction supports long service life when paired with proper pretreatment.
Whether replacing an existing membrane or upgrading a residential RO system for improved efficiency, the ULP1812-50 delivers dependable performance, reduced operating costs, and consistent purified water output.
