You must NOT submerge your entire K-Series device into water, as it is an electronic device. The only part that needs cleaning on your K-Series is the removable valve head and mouthpiece which is subjected to saliva. Please refer to your user manual.

Simply remove the valve head and mouthpiece and drop these two items only into water with POWERbreathe cleansing solution. Rinse thoroughly and allow to air dry.

Cold water sterilisation only.

Not suitable for sterilisation by boiling, steam, microwave or oven.
