How often should I clean the air filter on my LWG07-Series air conditioner?
The air filter should be checked and cleaned at least once every 2 weeks to maintain optimal performance. To clean it, remove the filter and wash it with warm, soapy water below 40°C (104°F), rinse it off, gently shake off excess water, and let it dry before replacing it. Operating without filters may cause failure of the unit. (Page 12)
