When should I replace the filter cartridge in my RAIN HARVESTING WFRC11?

[VanAnnie]

To ensure your RAIN HARVESTING WFRC11 Multi Action Slim Cartridge continues to deliver optimal performance, timely replacement is key. Here's when to consider a cartridge change: If the filter hasn't been used for a long time, it's best to disconnect the device, remove the cartridges, and store them somewhere cool and dry until you need them again. After not using the system for more than two days, flush the system for 10 minutes before use. For periods of non-use exceeding two weeks, replacing the cartridge may be necessary. Regular upkeep and cartridge replacement are vital for maintaining filtered water quality and your filtration system's efficiency.
