Check out the bags before buying. Make sure the bags are 1 micron, not 30 micron. I believe that Grizzly has switched to all 1 micron filters. The smaller micron bags help to increase airflow while also reducing particulates that will stay in your lungs. I have a Craftsman, (I won’t be buying any more Craftsman products), which has a top and bottom bag that are both 30 microns. I’m getting ready to order replacement 1 micron bags from American Fabric Filter.
