Review on Enhance Your Central Vacuum System with Nutone 391 Replacement Gallon by Dee Parson

I've had two back-to-back Chinese-made Nutone bags in my model 391 vacuum system separately. If you've ever had a bag rupture you'll immediately notice a drop in suction pressure. Be careful when removing the bag, because dirt will fall on the floor, and there will also be dust inside the drum - wear a mask. Also, dust gets into the secondary filter, which requires additional cleaning. Next I'm going to try some Made in USA bags, PN 44188, which should cost more.
