Vacuum Cleaners Discussions

Y does my TriStar CS have a 'dusty smell' exhaust when the bag is ˝way full? I'm using VAC (Vacuum America Clean) HEPA bags in the vacs (Aerus Lux Classic & TriStar CS) Makes me wonder VAC's HEPA bags let out fine dust btw I received a new hose from TriStar

Sebo and a few others make Vacuum Fresh odor control sticks that, if you suck one of them into your bag, will help reduce bag odor.  You could also cut up a car freshener, ___but___  I would be ___darn sure___ their or any in-bag deodorizers are not oil based nor flammable (nearly all vacs use carbon brush motors generating strong electrical arcs).
