Filters for Reverse Osmosis


Membranes on any filtration system need to be changed out when product water may begin to taste different or bad, indicating solids and organics are passing through the Reverse osmosis membrane. To be sure it’s the membrane, change the prefilter and postfilter first and check the TDS reading.

The life of the Reverse osmosis membrane cartridge depends mostly on the pH and hardness of the supply water to the Reverse osmosis system. Replace the membrane every 10 to 36 months.

Pre & Post Filters

It is recommended that all filters be changed at least annually or more frequently based on usage and local water conditions. The quantity and quality of the water processed effects the life of the filters.

The stages of your Reverse osmosis system typically range from 2-5 plus. Changing out the filters frequently helps keep higher quality water and can prolong the life of the Reverse osmosis membrane.
