So much this

Dust sources are:

Leaky air ducts: air ducts leak up to 11% on both the supply and return lines for a total of ~20% whenever your central air turns on. Yum fiberglass insulation!
Shed skin flakes: humans drop 1.5 lbs of skin a year. Dusty!
Dryers agitate clothes while heating them. Yum lint!
Shoes track in dust. Yum dirt.

You could consistently clean the air with a hepa filter that you clean regularly.

You could install a hrv system with a hepa filter on the intake duct while being anal about no leaks in the ducts. Then set it to make positive internal air pressure.

You could get a vaccume and mop roomba robot.

You could take off your shoes before coming into the house.

You could try to seal all your existing ducts.

Between all these suggestions, I think your dust would become negligible.

Fun.

One significant source of dust in households is textiles like rugs, pillows and curtains.

And you! you and other living things shed your skin cells, and so do all non living things which have wear and tear leave microscopic things behind (almost everything)

This isn't load-bearing wisdom so much as load-bearing questions

Lots of dust talk but very little about ashes.

The dust.
