OK. I know this is off topic and crazy but so am I. Just ask Ian the new owner of my ML Quest Z. I have a heat pump for my heat and A/C. My question is does anyone have problems with dust in their house? I replace my intake filters every two months with upgraded ones. Any unit or anything that can help? I have those Sharper Image Ionic Breezes and they do not do much with dust. Any advice on spending my money? Not that I need any....
