We have our own A/C unit, since the house air is frequently above 85F even in winter. The filters are the same sort of filters on a home HVAC system, and they work pretty well.
If you can arrange the floor plan, I'd recommend putting the roughing pumps in a room separate from the mass specs. We have a small room right behind our 70SE, and moving the RPs into that room made a big difference in the room noise level. You can't extend the vacuum lines too far, though, or you'll lose pumping efficiency. I've also known people who put a shell over the RPs if they couldn't move them, with a small fan for ventilation.
