Just wondering if it makes sense to run my shop vac (with 1um filter) overnight in the shop to act as an air filtration system. I don't have any specs on the cfm that it pulls which makes it difficult to know if this is useful or not. I already use the shop vac with my sander which helps a lot while working.

Anyone have other tricks for shop filtration/cleanup? I have a bunch of dust in the rafters which could be a pandora's box if I try to clean it up by blowing with compressed air and then trying to filter it.

cheers
