How often should I clean the air filter on my LG LWG07-Series air conditioner?
The air filter should be checked and cleaned at least every 2 weeks, or more often when necessary. To clean it, remove the filter and wash it with warm soapy water kept below 40°C (104°F), then rinse, gently shake off excess water, and allow it to dry completely before reinstalling. Operating the unit without a clean filter can cause malfunctions. (Page 12)
