Does anyone have any opinions on an ambient air filter? I am trying to make it possible to keep working rather than run out of the garage every time I use something without a dust port ( Palm sander, circular saw, router on dovetail jig etc...).
My shop is about 18' x 12' x 8'
I just got a little bonus check from work and I think this would be a wise way to spend it.

Thanks.
