I have noticed an excessive amount of dust in my home; especially in the master bathroom. It seems like I can't keep the furniture dusted enough. When I rinse the tub there is a coating of lint type dust that isn't visible until I rinse the tub by pouring water on the sides of the tub before filling it. I am wondering if there is a leak in our attic and perhaps the vent fan in the bathroom is allowing air flow from the attic to enter my home. I haven't had the attic inspected but the house was built in 2003 so didn't think I would have a problem. It is frustrating to try and keep up with the dusting! Have you heard of anything like this? What can I do to solve this problem?
