I bought this bag to use with my old model Eureka Mighty Mite which doesn't have the same suction power as my new Eureka Mighty Mite BUT I wanted these bags as I have a lot of decorative flowers, plants and dust dusts other things that get dusty but are brittle so I don't need a lot of suction power. They are great as they contain dust and I don't have to sneeze anymore! I'm glad Eureka thought of these types of bags because I don't have a heap filter on this vacuum.
