Sterilization treatment

The cartridge can be repeatedly sterilized. Sterilization should be carried out at regular intervals to ensure reliable removal of microorganisms and to maintain filtration performance.

Hot water sterilization

90℃

Chemical sterilization

Hydrogen peroxide solution: 5%
Formalin: 1%
Sodium hypochlorite: 10 ppm (chlorine water)
