I was doing some light housekeeping chores this morning with the wife and I am in charge of dusting. It's everwhere. We seldom open the windows more than 2 or 3 days in the spring and the fall. I love AC! I always replace the furnace filter every one to two months. I usually get the nice 3M ones for allergies. My house is 40 years old and on a crawl space (covered in plastic and lined with gravel). We are in the country. I dusted as a kid too and I don't remember it being this bad. Natually, my computers and HT equipment is a concern but I just hate dust in general. Any tips on this off-topic/on-topic issue?
