This cartridge is designed specifically for commercial settings or heavy duty use to help to remove excess moisture from inside the EcoWasher EXL unit which can cause deterioration of electronic internal components. Cartridges should be replaced every 6 months for best results.
 
Simply remove the old cartridge in your unit, install the new one, and remove the seal sticker from the top of the cartridge before use.
