How often should I clean the air filter?
You should check and clean the air filter at least once every 2 weeks or as necessary to maintain optimal performance of the air conditioner. Clean the filter with warm, soapy water below 40°C (104°F), rinse it off, gently shake off excess water, and let it dry before replacing it.
