Heed this advice:
Don't EVER use the white, singly ply bags in an Air-Way. They are horrible, clog within moments, leak dirt into the motor, and fill the air in the room with dust. ONLY use a genuine Air-Way bag with the words "Air Way Sanitizor" embossed into the plastic bag top, OR, make a HEPA bag for the Air-Way. To make a HEPA bag, remove the plastic bag top from an Air-Way bag. Cut a HEPA cloth bag so it's long enough to fit the Air-Way bag chamber with a little cloth sticking up. Place the bag into the chamber, place the plastic bag top into place, and fold inwards the remaining cloth all around the bag's circumference. Close the lid, and you now have a HEPA Air-Way bag.
