I cannot emphasize enough the importance of keeping the filters clean. The #1 cause for projector malfunction is running a projector with dirty filters. I can almost guarantee that when a projector fails, I will find that the filter has a layer or two of filth or dust on it.
When you don’t clean your filter, you will notice that your projector gets dimmer. This means you just cut your bulb’s life span by a significant percentage. When you get to this stage, it’s usually a matter of hours before your projector overheats and your bulb cracks.
Please take the time to slide the filter(s) out of your projector and dust them off.
How, you ask? With projector OFF, I clean it by running my fingers over the foam above a trash recepticle. If you have a small brush or dry cleaning towel, you can use that too. Don’t be so rough because you may tear foam. Slip back in the appropriate slot.
Can I use water? You can, but MAKE SURE foam is completely dry before inserting it back in slot!
The unit pops up an automatic warning when it needs to be cleaned. Get in the habit of cleaning it once every other month. You will extend the life of the bulb and the unit. You will also need to go into your projectors menu and reset the filter hours so that it reminds you to clean them soon again.
Please Note: Some units have more than one filter.
