How often does the air filter need to be cleaned or replaced?
Clean the air filter once every 3 months, or more often if you're using the projector in a dusty environment. If it's not cleaned periodically, it can become clogged, preventing proper ventilation and causing overheating and damage to the projector. See Cleaning and Replacing the Air Filter.
