For finer filtration than that provided by the stock bag, choose this upgraded 5-micron filter bag. It offers the same size and capacity as the 30-micron bag that comes stock with your Dust Right 1250 CFM Wall Mount Dust Collector, but is made from heavy-duty cloth for much finer particle retention. Ideal for capturing the fine dust generated by sanding. The clear window on the side shows the dust level so you know when it’s time to empty. And thanks to the zipper on the bottom of the bag, emptying is an easy chore.
