Cleaning a washable filter

If the amount of dirt on the filter is minimal, use a vacuum or compressed air to remove it. If you
use compressed air, the air must move through the filter in the opposite direction of the air flow
indicator on the side of the filter.
Warning! Failure to comply with the following could result in serious injury.
The installation of a filter that has not been allowed to dry completely can cause an electrical short
and damage the projector.
1. Hold the filter on an angle under warm running water so the water flows through the filter in
the opposite direction of the air flow indicator on the side of the filter.
2. Rinse the filter thoroughly.
3. Submerge the filter for a minimum of 30 minutes in a container of warm water and two
tablespoons of mild detergent or liquid dish soap.
If the filter is extremely dirty, move the filter from side to side occasionally, or remove the
excess dirt by brushing both sides of the filter with a soft brush.
4. Rinse the filter thoroughly by holding it on an angle under cool running water. The air flow
arrow on the side of the filter should face down.
5. Repeat steps 3 and 4 if the filter still appears dirty.
6. Shake the filter over a container until most of the water is removed.
7. Place the filter on its edge on a flat, stable surface and allow it to dry thoroughly.
