How often should I clean the air filters and vents and how do I clean them?

• Clean the air filters and intake vents after every 100 hours of use. If they are not cleaned periodically, they can become clogged with dust, preventing proper ventilation. This can cause overheating and damage the projector. Follow the instructions for cleaning the air filters and vents in the User's Guide.
  
  If the dirt is difficult to remove or a filter is broken, replace the air filters. Air filters are included with each replacement lamp, but if you need to replace the filters before a lamp change you can purchase them separately from the Epson Store.
