Cleaning the Filters

Some projector models use one or more filters to keep the fans free from dust and other particles, and should be cleaned every 500 hours of operation. In dusty environments, it is recommended to clean the filters more frequently. If the filter is dirty or clogged, your projector may overheat, which can lead to premature shutoff, reduced lamp and or projector life. Projectors equipped with filters will display a message when the filters must be cleaned; the default interval is normally 500 hours.
