Reverse osmosis system maintenance keeps your system running at top performance level. Here are 3 practical tips from John, our Master Water Specialist, to help you maintain your reverse osmosis system.
Why is reverse osmosis system maintenance important?
Reverse osmosis (RO) systems are great to have under your sink to provide you high-quality water to drink, cook with, or run to the ice machine.

1. Change the reverse osmosis membrane and RO filters.
No matter which style of system you have, whether it's a quick-change, an older style with drop-in cartridges, or even a countertop system, it's very important to replace the prefilters, the postfilters, and the RO membrane periodically.
