Reliable 1812 RO Housing for Water Filtration
The 1812 RO housing is a key component in household and small commercial reverse osmosis systems. It supports standard 1.8″ × 12″ (1812) membrane elements and helps ensure stable, dependable water purification. Because it is sized to industry standards, this membrane vessel works with most residential reverse osmosis membranes, making it a versatile choice for upgrades and replacements.
How the 1812 RO Housing Works
In a reverse osmosis system, feed water enters the 1812 RO housing and flows along the surface of the membrane housed inside. First, pressure pushes the water through the membrane, and then it separates purified water from contaminants. As a result, your RO system delivers clearer, fresher drinking water without adding complexity. Because of its simple design, this housing fits under‑sink, point‑of‑use, and compact RO setups.
