D&D Replacement Membranes will prolong the life of your Reverse Osmosis unit.
The original membrane in your unit should last around 2 years, however this depends upon on the quality of water in your area. The more contaminants in the water shortens the life of the membrane.
These high quality thin film coverings can be used with any manufacturer's RO unit that takes a standard membrane.
This replacement membrane is designed to fit the 150 Gallon D&D RO unit.
Note that a matching flow restrictor must be used on the waste pipe specific to the membrane output.
