BenQ projectors are sturdy machines requiring very little upkeep. However, you still need to do some regular light maintenance and cleaning to keep your Ben Q projector working well.

Important safety tips

Before cleaning or doing any maintenance, keep these important safety tips in mind:

  • Never remove any parts of the projector except the lamp or the air filter.
  • The projector should always be turned off and cooled down before doing any maintenance or cleaning.

Cleaning a Dirty Lens


  • Get rid of a build up of dirt by using a non-abrasive lens cleaning solution.
  • Isopropyl alcohol can also be used to clean the projector lens.
  • NEVER apply the cleansing solution directly to the lens.
  • Apply the cleaning solution to a soft, dry and lint-free cloth bought at a camera or photography shop. You can also use a proper photographic lens brush to gently wipe the lens surface.
  • Wipe the cloth gently in circular motion.
  • NEVER touch the lens with your finger since oil from your skin can leave a mark.
  • Replace the lens caps if are not using the projector immediately.

Clean the filter

Failure to clean the filter regularly may also result in an automatic shut down of the projector from overheating.
A message warning you to clean the air filter will appear periodically every 500 hours. Some BenQ projectors will also have the information on the menu:
Menu Option 1: Advanced Setup/ Dust Filter/Dust Filter Hours menu
Menu Option 2
: Information/ Dust Filter Hours

  • Don’t wash the filter with soap or water as this can damage the filter membranes.
  • Vacuum the filter with a vacuum cleaner designed for computers and other office equipment. DO NOT use a regular vacuum cleaner.
  • Use a can of compressed air to blow the dust away.
  • Gently shake out the filter to release any dust.

NOTE: Never clean the inside of your projector with compressed air. All this does is blows the dust deep inside the projector.
