Replacement Filters for RO & RO/DI Systems

Want to know how often to change filters in a reverse osmosis system? The answer varies. For an average aquarium with decent tap water, the sediment and carbon RO filter replacement should be done by 6 months; the deionized resin cartridge a year; the TFC membrane two years. When the carbon and sediment need to be changed, the pressure will drop in the system. The DI cartridge is exhausted when TDS (total dissolved solids) of the product water measures above 2-5ppm.

Need to know how to replace filters in a reverse osmosis system? For 3 stage reverse osmosis replacement filters, first turn off the feed water. Then, unscrew the sediment and carbon canisters with an RO wrench. Remove the RO membrane, replace the carbon and sediment, then flush the system to remove particles. Next, (re)install the RO membrane and flush again. Finally, replace the DI cartridge.
