CSM TFC Residential RO Membranes

Overview

CSM Residential Thin-Film Composite (TFC) Reverse Osmosis (RO) Membrane Elements provide effective water purification by reducing contaminants such as carcinogens, THMs (trihalomethanes), heavy metal ions, bacteria, and viruses. Designed for residential water filtration systems, these membranes are available in multiple diameters (1.8″, 2.0″, and 2.9″) and lengths (10″ and 12″). CSM RO membranes offer reliable, cost-effective filtration performance with excellent salt rejection, making them a practical choice for household drinking water purification.
