When and how should I clean or replace the air filter?
Clean the filter if dust collects on the air filter or vent on the side of the projector. See Cleaning the Air Filter and Vent for more information.
If the filter is difficult to clean or damaged, or if the overheating message appears after cleaning, you need to replace the filter. See Replacing the Air Filter.
