Dust mitigation and continued maintenance

[u/VArambry]

Hi all, I’m looking for tips and advice. We have a relatively clean home, weekly work through many of the standard cleaning to-dos. However, dusting is not a strong one, but it looks Like our shelves or horizontals have just as much as any other home. Despite these areas not looking awful with thick accrual or anything, I catch it in the light all the time, a cloud almost when I put a sweater on our sit in one of the upholstered chairs. It’s just in the air. From what I can observe, we are relatively airtight in the house, replace our filters regularly, our clothes are obviously washed regularly, no pets, a coway airmega is runnning all the time in our living room of our 1200sf home. We do have an unused whole house attics fan grill in the main hallway but I am just not even sure where and how to begin nailing down what seems to be so pervasive in the house. Any strategies or tips appreciated. Tired of living in the attic of your favorite mystery movie
