Getting rid of sanding dust before priming?
Doing what I hope will be the last sanding of drywall mud. Do people typically remove the dust before priming and painting? If so, how?
When I use a bench brush, I notice that small clumps of dust will be left here and there, which I'm sure is worse for a paint job than non-clumped dust widely distributed on the walls.
Maybe compressor and blow gun? That will certainly blow the dust off, but with all the dust circulating in the air, some of it will land back on the walls, though it wouldn't be clumped, so I suppose that's not bad.
Shop vac? Seems like a lot of work.

To answer your initial question, yes, you at least need to make an effort to remove the dust as painting dust serves little purpose.

You just do the best you can. A soft broom is typically what I use. If I did it a lot I would probably get a dust mop. The dust is so fine that anything you miss just gets absorbed into the paint. The wall may not appear completely dust free, that's normal.
You always very lightly sand a wall between coats, so after you prime you will lightly sand again. This is not an aggressive sanding, just enough to knock off anything that would otherwise feel rough to your hand. A 10x10 section of wall would take maybe 10-15 seconds to sand with a pole sander. That's how quick.
