Got mine, and I've only salted two big maggots on the trash can lid, as it's too cold here as well.
I fixed the loader lid when the locking tab snapped off when I first opened it, using an epoxied sawed-off bottle top from a 12oz Gatorade. :D

It's funny to me that who I believe to be the wise will just say you must clean periodically in order to rid dust. It's not practical to filter dust without a method considered overkill in the minds of most people. Like most people, I'm cheap. I don't want to have to get a HEPA air purifier...

I'm using Air Penetrators in my scratchbuild but currently have them plugged in headers on the mainboard (for rotation rate reporting). I'm not sure...
Just a FYI, there is an LCD Conditioning option in the Menu that will cycle the display through a bunch of colors. Maybe get a screensaver that'll do it (oh nice idea I just came up, surely this exists) and/or have your wallpaper change constantly.
I just realized your situation is more about covering a hole that happens to be near a fan. Foam-lined acrylic sheet could work, although probably requiring more effort than you want.
I will probably try women's peds next, for a filtering material.
