50 GPD Coway 11'' M Replacement Membrane – The Heart of Your Filtration System

The Coway 50 GPD 11'' M Reverse Osmosis Membrane (CRMFM11-50) is the most important element and the true heart of the Coway Cave Spring P-160L under-sink system. This original replacement cartridge is responsible for capturing the smallest and most dangerous contaminants from drinking water, which standard mechanical and carbon filters cannot handle.

The membrane acts like a microscopic sieve, allowing only pure water molecules to pass through, while rejecting the most difficult contaminants into the sewage system. It has been rigorously tested and proven effective in eliminating heavy metals from water (such as lead, cadmium, barium, selenium, arsenic, and even radium 226/228). Additionally, the membrane provides an absolute barrier against harmful chemicals, herbicides, pesticides, and dangerous aquatic microorganisms.

This product is WQA certified and meets the stringent NSF/ANSI 58 standards for reverse osmosis systems. The original Coway brand quality guarantees full sealing, hygienic replacement, and optimal efficiency of the entire filtration system, allowing for crystal clear, tasty water.

Recommended replacement frequency: every 18–24 months.
