Generally we expect 2-3 years from a membrane but tap water quality has the final say. We generally use rejection rate as a guide and don't replace the membrane untill we see the rejection rate start to fall into the lower 90's or the membrane just stops producing water which can happen all at once. Some customers like to use the 2-3 years as a guide and just change the membrane regardless of performance.
