Where does all the dirt go when you vacuum? It is deposited into you vacuum cleaner bag. The main goals of a vacuum cleaner bag are to be flexible enough to hold the debris and also to keep that debris from being released back into the air. The Miele 7282050 Hyclean Vacuum Cleaner Bag does this and a lot more. Miele 7282050 is made of a new material that has a complex web of 3-ply random-spun fibers. Conventional dust bags do not retain as many tiny particles and allergens. The improved composition gets rid of any risk of clogging and improves the suction performance to peak levels.
