Depending on the water quality and usage, the membrane should be changed every 2-5 years. **Please note that the design of this filter has been improved to improve its performance. The black stripe that was at the end with the two O-rings is now on the opposite end. This membrane still fits all systems, if not better than before the design change. </p>
