Budget Paper Sebo Dart Vacuum Bags Have been used for many years. They come with the Small Green Dustcap. Push in the top before you remove the Dust-Bag from the Vacuum.This stops the dust coming out whist you dispose of the bag. With all Vacuums if your machine is under warranty you must use the genuine Sebo Vacuum Bags or you could invalidate the warranty. Do Not empty them out to reuse. As the Sebo Bags get used it blocks the walls of the bag so every time you replace it with a new one you effectively are replacing part of the filtration of the machine. For Better Levels of Filtration & Extended Motor Life Use Dart Hepaflow Hi Filtration Bags. This is Especially the Case where Dust Allergies are an issue.
