Thanks for giving me a virtual kick in the pants with this renewed filter bag discussion. Just placed my order on Amazon for a one micron bag after spending more than an hour cleaning up fine dust all over my shop. Curiously a lot of it also come from the noise muffler/filter bag area on the output side of the CW. I have got to also duct that into my main collector hose as I set up my new rolling cart for the CW and the Planner. Thanks again
