I spent half a day on Christmas dusting and vaccuming. It occured to me that the filters hadn't been changed since maybe a year ago. I realized it when I saw just how dusty the place gets very quickly.
Its recommended that filters are changed every three months. If you have not done it before, they're really cheap (usually around a dollar a piece) and will help you have a cleaner environment. The dumber part in my case... is that Ridgepointe provides replacements for free. I just have to go to the office to request new ones.
Hopefully it'll get dusty in here a little more slowly now.
UPDATE - 12/30 at 2 a.m.: One of the problems the heat/air conditioning has had for about a year is a random and rather loud rattling. I discovered when I changed the filters that there is a little metal tube that had wiring inside of it, and it was positioned in a way that it rested on one of the filters. A little screwdriver magic to reposition it and the unit hasn't rattled the rest of the day. I'm a freakin' genius.

These stopped trapping new dust a long long time ago... in a galaxy far far, away.
