Indoor environment geeks run their own air purifiers put together from PC fans and oven filters. Apparently PC fans designed for it are much less noisy than the commercial alternatives, so you can run it on constant speed.
I've wanted to try building one myself, but unfortunately even the minimal woodworking required is a bit of a challenge for me.
