Dust is always built inside the projector, not outside; you must uncover your Optoma projector cover. I know this may be hard for you but not more. Follow the steps to find it properly.

  • Carefully discard the lamp or LED
  • Loosen the two screws of the lamp assembly
  • Instantly hold the metal piece and carefully take the lamp out

Note: if you feel the lid is not lifting, then use screwdrivers to rip it off.

  • After you remove the lamp, loosen the screw present at the bottom of the Optoma projector 
  • Now remove the screw at the backside
  • Now carefully open the cover by pulling the little plastic clip at the side of the projector. For this purpose, we use the screwdriver

How to Clean the Dust Filter of an Optoma Projector?

After you remove the interior dust, you must remove or clean the dust filter. The dust filter is an excellent feature in the Optoma projector; it is a piece of cloth that prevents the dust from coming in. from this, the dust can’t enter the projector interior and prevent the Optoma projector from overheating or starting flickering. 

According to Optoma, you must clean or replace the dust filter at least once every three months. If you use your Optoma projector in a dusty environment, do this often. 

Follow the steps if you want to remove the dust layer from the dust filter. 

  • Unhurriedly remove the dust cover present at the side of the Optoma projector, and pull it without damaging any part
  • Remove the layer of dust present on the dust filter; for this, use a small brush or vacuum cleaner if available. If the filter is full of heavy dust now, you have to replace it with a new one
  • Now place the filter in its place

How to Clean the Lens of the Optoma Projector?

Often, the picture gets blurry because scratches and fingerprints are available on the lens, which makes the projection worse. To get rid of this, follow the steps. 

  • Now take the lens out
  • Pour some drops of cleaning solution on the lint-free cloth
  • Wipe the cloth carefully in a circular motion on the lens
  • After you clean the interior, now reassemble the parts of the cover


  • Don’t touch the bare finger on the Optoma projector lens because the finger contains the oil which gets burned when the lens gets heated up. Fingerprints are the worst to remove from the lens. 
  • Please don’t use another cleaning solvent because they are strong and may damage the lens. Don’t use alcohol either on the projector lens.
  • And also, don’t use the paper towel or tissue because they have rough fiber which leaves scratches instead of removing them.
