Cleaning Air Filters on Projectors
Some projectors, such as certain Hitachi models, let you know when it is time to clean the air filter.
Others projectors, such as certain Epson models, simply tell you that it is overheating and past time to clean the air filter.
While projector manuals say to clean the filter after every 100 hours of use, it’s a good idea to check it every month, especially if your room gets dusty or if you have an outside door or keep your windows open.
How you clean the filter varies with each projector but the basic principals are the same.
1. Turn off the projector and let it cool down.
2. When cool, unplug the power cord.
3. Find the filter. It is usually on the side or bottom of the projector. It looks like a thin, flat sponge, usually covered by a plastic grid.
4. Remove the filter. On Epson projectors, the grid is attached to the filter. On other projectors, the filter and grid are separate pieces.
5. Clean the filter by either vacuuming it or washing it under running water. If you wash it, let it dry thoroughly.
6. Before replacing the filter, look inside the opening when the filter was. If it is dusty, vacuum it out also.
7. Replace the filter. Plug in the power cord and you are done.
