Description
Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to remove ions, unwanted molecules and larger particles from drinking water. ... The process is similar to other membrane technology applications.
Answer: The life span of a RO membrane depends on 1) the contaminant level of your water, 2) the maintenance program you follow for changing your pre-filters and 3) the amount of water you use. Membranes can usually operate well for a couple of years but they will last up to five or more years under good conditions
