When and how should I clean or replace the air filter?

• See below.

  Cleaning the Air Filter and Vents

  Clean the projector's air filter or vents if they get dusty.
  1. Turn off the projector and unplug the power cord.
  2. Gently remove the dust from the air intake vent using a small vacuum designed for computers or a very soft brush (such as a paintbrush).
     

     Note: Do not vacuum the air filter, or you may damage it. Do not rinse the air filter in water or use any detergent or solvent to clean it.

     Caution:
     Do not use canned air. The gases may leave a flammable residue or push dust and debris into the projector's optics or other sensitive areas. If the streaming media player is not installed, disconnect the HDMI and power supply USB cables from the projector during cleaning. Otherwise, the ports of the cables may get dusty, resulting in a malfunction.
