- Make sure the projector is powered off and allow it to cool down for at least 20 minutes.
- Remove the air filter assembly from your projector housing
- Airflow is important for cooling the lamp assembly and electronics, but dust inside your projector will make for a poor image. If your air filter is particularly dirty, gently rinse it with soapy water. Let it dry completely.
- Vacuum the filter, both inside and out or Use a can of compressed air to blow away any debris that has gathered on the lens. Remember to keep the compressed air can upright, and to spray in short bursts to avoid damaging the glass.
- Using either single-use lens wipes or spraying lens cleaner on a microfiber cloth, gently wipe the lens in circular motions.
