Dust!

I'm so glad we all don't have allergies here. With the weather warming up, our lack of "good housekeeping" and animals there's always some kind of allergen around. I swear the day after I vacuum there's dust every where again. It seems almost pointless. I kind of wonder if the furnace filters have something to do with the dust. Maybe they need to be changed? I don't even know how many we have. LOL I just imagine that nothing's ever been done and the dust just keeps recirculating. I bet that's what it is! UGH
