The reverse osmosis membrane is the heart of all reverse osmosis systems (including countertop, under sink, and tankless). Typically, all the systems come with the membrane but have a life expectancy of two years. After that, you need to replace it, and that’s where the reverse osmosis replacement membrane comes in.
Reverse osmosis filters and membranes play a vital role in your reverse osmosis water system. It is recommended to change the reverse osmosis post and pre-filter every 12 months and the membrane every 24 months. By doing so, you will make your reverse osmosis water system last longer.
