Why is my shop vac louder than normal?

  • If your vacuum has suddenly become very loud, check the filter, as it may be dirty. When the filters on a vacuum become excessively dirty, the vacuum may start running louder because it is working hard to create suction. ... Replace the filters once they are dry, and your vacuum should run at its normal sound level. A quietest shop vacs is an essential part of any workshop or work area. Using the household vacuum to clean up sawdust, plaster dust, or bits and pieces of scrap material will shorten its life… and possibly your own if you get caught!
