What is the function of the 40-inch reverse osmosis membrane?

The 40-inch membrane is the heart of the reverse osmosis system. It removes salt, minerals, and other contaminants from seawater, delivering pure, drinkable freshwater for marine, industrial, and residential applications.

How often should I replace the RO membrane?

With proper flushing and regular maintenance, RO membranes typically last 3 to 5 years. Actual lifespan depends on usage, feedwater quality, and system care.
