Do any of you have bad dust problems with your collection? I used to live in a studio apartment with a window-mounted AC, and I had very little dust, I'd need to dust maybe once a month. Now I moved to a swankier place with central air and one of those electronic air filtration unit things in my bedroom, and my stuff gets dusty so fast. I'm not sure what's to blame--I changed the filters in the air ducts and washed the HEPA filter, but still, after a few days it's dust city. Anyone have any ideas on lessening dust?
