A word about dust filters in LCD projectors

Dust filtersBe sure to regularly remove your filters and either clean or replace them according the manufacturer's instructions. You'll be amazed at how fast they become clogged up. A dirty filter will cause your projector to overheat and shut down and shortens lamp life. Even worse, the dust that collects on your filter will eventually make its way into your projector and depost itself on the red, green and blue LCD panels. Once this happens you will have colored spots in your image and your projector will need a professional cleaning.
