Watts Premier (105331) RO PURE 50 GPD Membrane

The Watts Premier 105331 RO PURE 50 GPD Membrane is a residential reverse osmosis membrane designed exclusively for the RO-PURE and WP-RO4 systems, delivering up to 50 gallons per day of purified water. This semi-permeable membrane removes up to 99% of dissolved solids, heavy metals, and cysts through advanced TFC (thin-film composite) filtration technology.

COMPATIBILITY & APPLICATIONS

System Fitment

The Watts Premier 105331 membrane is engineered specifically for the RO-PURE and WP-RO4 reverse osmosis systems. This membrane will not fit Watts 1/4 Turn KWIK Change filter housings or other manufacturer systems. It is designed for residential point-of-use applications where municipal or well water requires reduction of dissolved solids, heavy metals like lead and arsenic, and microbiological cysts. Ideal for under-sink installations in homes, small offices, and light commercial settings where daily water consumption does not exceed 50 gallons.

💧 Membrane life is directly tied to pre-filter maintenance. Replace your sediment and carbon pre-filters on schedule to protect the RO membrane from fouling and maximize its 2–5 year lifespan. Neglecting upstream filters is the most common cause of premature membrane failure.
