However, it is not recommended to wash your water filter cartridges in general. Water filter cartridges should be to replace periodically or after filtered certain water flow in order to make sure the cleanness of your drinking water.
If water filter cartridges are not replaced regularly, the dirt will clog the outlet of your water filter.
It will also cause the following potential problems:

  1. First, because of the increase in water pressure, particles will come out with filtered water. 
  2. Carbon cartridge becomes less or not effective, so residual chlorine and agricultural chemicals cannot be removed.
  3. If you are using RO system, the membrane will become less effective, so heavy metal, limescale, bacterial etc.
  4. Bacteria cannot be removed through UV ultraviolet germicidal lamp or UF hollow fiber membrane filter.
