deformed or rounded. Before reinserting the air filter,
make sure that it is undamaged and dry!
1. Remove the EVA air filter and the CON air filter from the

damp, soft, lint-free cloth. If the filter is heavily
contaminated, clean it with warm water mixed with a
neutral cleaning agent.

completely. Do NOT insert a wet filter into the device!
4. Reinsert the EVA air filter and the CON air filter into the
