How often do you clean projector filters?
As above really...I'm finding we're needing to clean some of our projectors monthly all of a sudden, lest they overheat..this seems a tad excessive..
I'm chatting to our site manager about the air circulation system here...I'm wondering if it's distributing cack all over the shop all of a sudden...blocking the filters. It's a possibility..

Projector filters get cleaned every holiday here: about once every 6 weeks... except the Casio ones - they just get dusted

in my limited experiance the dust filters do not cach all of the dust and other vents and holes etc allowing dust and muck in so it may be a problem with large amounts of dust actualy in the projector colecting and stoping air flow or causing over heating might be worth giving it a good blow out with compresed air. thats what we do because other wise our equipment gets verry cloged even when we clean filters regularly.
We clean ours abought once a term unless its in a perticularly dusty place such as tech.

I was told at a recent training course from Epson, that projectors should never be cleaned with compressed air.
All it does is blows the dust into the inside of the projector.
In the past I have just blasted the filter with compressed air and blasted all the little holes on the projector to get rid of the dust, but apparently all this does is blows the dust inside the projector and then when it turns on it melts the dust onto the colour wheels and leaves a shadow on the image.
Not sure how much truth there is in this, but I haven't used compressed air on a projector since.
Removed filters, blasted with compressed air outside, and then refitted. Any dust on the outside of the projector just brush it off.
The trainer told us we should use a vacuum cleaner, but one of our techs did some research and apparently mains powered vacuum cleaners should not be used on any electronic equipment due to static, so only hand held ones can be used, which we don't have.
Not sure how much truth there is in that either...

Once a month. I use a Dyson hand-held.

well i would be concernd abought static build up in a hand held hover as it is not grounded :s. and it may be worth taking the bulb out and blowing the dust out rather than in this works well for us. and it may also be worth checking the fans are running corectly.

When I walk past one and there's a big "CLEAN FILTER" message on the whiteboard.

Admit it, you just reset the clean filter usage meter and walk off

Beginning of each month. Would have done it today but I had a problem that needed sorting before lessons started.

Hmm...I take our filters off and out of the room before air-dusting the things, but STILL they seem to overheat and the filters are WELL AND TRULY clogged up in under a month...
Either the kids are shedding, the cleaners are running no filters on their vacuums, or the air system in this place is moving dust from A to B to C...

Shouldn't be a problem. It has anti-static carbon fibre brushes so there should not be much static generated, if any.

My techy goes round on a cycle and cleans them all, obviously if they come up sooner than the cycle, which is usually every half term, they get done but we are about on top of those rapid users.

Uni cycle or 2 wheeled rayleigh?
