Review on BOSCH VAC012 Vacuum Air Filters - Set of 2 by Joyce Wright

I have replaced the filters on a Bosch 3931A-PB vacuum originally purchased from Revain on 11/14/2011. The original filters must be replaced! Model 3931A-PB is quite satisfactory. I installed connectors to connect to a Sawstop Contractor saw, a Delta 14" band saw, and a Grizzly G1276 belt/disc sander. The dust extraction doesn't meet any specific dust extraction standards, but makes cleaning my garage/ driveway workshop that much easier.
