I have allergy to just about everything , paticularly dust . I have switch my upright to the Oreck use the hypoallergenic bag . the upright I use originally seem to be do the job , however , ten minute after vacuumm I notice dust particle settle on the furniture and everywhere else . shortly thereafter I have a migraine . since I switch to the Oreck , I no longer have to dust everything after vacuumm and have reduce my allergy symptom significantly . the Oreck contain the dust particle in the hypoallergenic bag , be light weight and flexible enough to vaccum in tight area . love it , love it , love it !!!
