Cleaning the housing

components from moisture. Do not use any aggressive cleaning
agents such as cleaning sprays, solvents, alcohol-based or
abrasive cleaners to dampen the cloth.

water mixed with a neutral cleaning agent.
3. Allow the filter to dry completely. Do not insert a wet filter
into the device!
