6. How do I properly maintain my reverse osmosis system?

The filters of your RO system should be changed periodically. In general, both the re- and post-filters should be replaces about every six months, or at least annually; however, the maintenance schedules may vary due to local water conditions, the quality of water being filtered, and the manufacturer’s recommendations. The reverse osmosis membrane normally lasts between 3 to 5 years. WQA suggests you closely follow the maintenance schedule provided by your water treatment specialist of the manufacturer to ensure that the system is in proper working order.
