Home » Residential RO Membranes
The 2012 reverse osmosis (RO) membrane is a compact element designed for small-scale residential and light commercial applications, falling within the standardized RO membrane size range. It is widely used in small water purification units, countertop water purifiers, direct-drinking water dispensers, and space-constrained water treatment systems. Compared to the 1812 model, the 2012 membrane—while maintaining a high salt rejection rate—typically offers a higher permeate flow rate or a more compact design, making it better suited for small-scale, high-efficiency water purification needs.

High-Efficiency Filtration for Residential Applications
The residential reverse osmosis (RO) membrane is the core filtration component of household water purifiers. Utilizing advanced RO separation technology, it employs pressure to force water molecules through an ultra-thin semi-permeable membrane while effectively blocking dissolved salts, heavy metals, bacteria, viruses, organic compounds, and other harmful impurities, thereby producing clean, safe, and healthy drinking water. Serving intermittent, low-load household drinking water scenarios, the equipment is small in size, easy to use, and low in cost, providing families with a safe and convenient solution for instant drinking water.
