Terrible Dust in the MBdrm only - cause?
Posting for a non-tech friend. She has constant dust on her master bedroom furniture. Dusts in the morning and by afternoon it's dusty again. The rest of the house doesn't have this problem. The dustbunnies under the bed are REALLY bad. She changes a/c filters often and the return in the attic is correctly installed. The woman keeps an uber-clean home. Short-haired dog. Popcorn ceilings in entire house. Berber carpet in this room only. Could the berber have anything to do with it? Any ideas?
