Replace the membrane in the D&D 50 Gallon Reverse Osmosis unit to extend the life and performance of the unit.
The Replacement RO 50 Membrane is designed to fit into any RO unit that matches the specifications. It is recommended that the membrane is replaced every two years, or sooner if the water in your area is particularly poor.
Simply remove the old membrane and replace with the new one to continually clean tap water off all contaminants and toxins.
Note that a matching flow restrictor must be used on the waste pipe specific to the membrane output.
