My room is always getting dusty even though I clean it all the time. Probably my dead skin but my allergies is acts up like mad. Sometimes I can't breathe, so then I don't even bother studying in my room.
I am wondering what type/brand of air purifiers you guys have at home? I was looking at the Oreck XL air purifier at Costco and it seems pretty good. However, there are always those people online that dislike it. Bad thing is it costs ~$300.
