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

  • See below.

    Cleaning the Air Filters and Air Intake Vents

    You need to clean the projector's air filters and air intake vents in the following situations:
    • The filters or vents get dusty.
    • You see a message telling you to clean it.

      Note: To receive air filter notifications, make sure the Air Filter Notice setting is set to On in the Extended menu Display settings.

    • The projector's Filter light flashes orange.

    Note: The projector has two air filters on the front. The illustrations here show cleaning the air filter on the right, but the steps are the same to clean either filter.

    1. Turn off the projector, wait for the projector to beep, and unplug the power cord.
    2. Loosen the screw securing the air filter cover and open the air filter cover as shown. (It is attached with a cord.)
    3. Grasp the tab on the air filter and pull it out of the projector.
    4. Tap each side of the air filter 4 to 5 times to shake off any excess dust.

      Caution:
      Do not use excessive force when tapping the air filter, or it may crack and become unusable. Do not rinse the air filter in water, or use any detergent or solvent to clean it. Do not use canned air; the gases may leave a residue, or push dust and debris into the projector's optics or other sensitive areas.

    5. Vacuum the front of the air filter (the side with the tabs) to remove any remaining dust.

      Note: If dust is difficult to remove or the air filter is damaged, replace the air filter.

    6. Place the air filter back in the projector as shown and push gently until it clicks into place.
    7. Insert the tabs on the right side of the air filter cover into the notches in the projector. Then close the air filter cover and tighten the screw to secure it.
    8. Repeat these steps to clean the other air filter.
    9. Use a vacuum cleaner or soft, long-bristle brush to carefully remove dust from the air intake vents on the side and bottom of the projector.

      Note: Clean the projector's air intake vents periodically, or whenever you notice dust on the side or bottom of the projector.

    Replacing the Air Filters

    You need to replace the air filters in the following situations:
    • After cleaning an air filter, you see a message telling you to clean or replace it.
    • An air filter is torn or damaged.

    Note: To receive air filter notifications, make sure the Air Filter Notice setting is set to On in the Extended menu Display settings.

    You can replace the air filters while the projector is mounted to the ceiling or placed on a table.

    Note: The projector has two air filters. The illustrations here show replacing the air filter on the right, but the steps are the same to replace either filter.

    1. Turn off the projector, wait for the projector to beep, and unplug the power cord.
    2. Loosen the screw securing the air filter cover and open the air filter cover as shown. (It is attached with a cord.)
    3. Grasp the tab on the air filter and pull it out of the projector.

      Note: Air filters contain polypropylene. Dispose of used air filters according to local regulations.

    4. Place the new air filter in the projector as shown and push gently until it clicks into place.
    5. Insert the tabs on the right side of the air filter cover into the notches in the projector. Then close the cover and tighten the screw securing it.
