Probably never get enough CFM or inches of vacuum or whatever.

The furnace filter is on the list!

You could get a cheap box fan and a 2" thick pleated furnace filter
the same dimensions as the fan. Duct tape the filter to the fan where
the air is drawn in and let it run before and after you blow the dust
off everything. You could assemble a couple per room and let them blow
the air in a circle. I designed a stand alone air filter cabinet for a
printing company years ago that used cascading air filters of increasing
density to help remove paper dust from the air.

TDD

I put fans in several windows in distant parts of the house blowing in
so the house is pressurized. Then I keep the windows open in the room
where I am sanding, even taking out the screens if possible. All the
dust goes out the window and makes a mess outside, but it keeps the
dust from getting into other rooms,
