They go perfectly with my Oreck XL! I save so much money by ordering from Prime. An Oreck store near my house is charging $40 for 6 packs! You can't beat the savings plus free shipping! In my opinion, hypoallergenic bags are better than regular bags because they feel more durable and I've never had a bag tear before. I have two German shepherds and two parrots, so the coat, feathers and seeds need to be cleaned a lot and often. Normally I have to change my bag every week.
