I have an unfinished basement. It would be a great place for a workshop but some hobbies don't do well in a dusty environment. Would setting up an air purifier help? Even then I'm concerned it wouldn't get the entire volume of air.

One idea is to just cover the area in a tarp (or something more permanent) while not in use.

I hate to tidy up and will very likely forget even if I don't get lazy and I don't want to have stuff get dusty because it's laying out for a while.

I assume the dust is coming from the rafters when we walk around upstairs but I'm not certain.

The hobbies are pretty varied. Electronics (like Arduinos), sewing, painting, etc. Nothing crazy like woodworking or metalworking which create their own dust though. The dust is just the normal dust you see in basements lol.
