These high efficiency disposable bags will make your life easier while increasing the performance of your vac. When the vac is turned off, the filter deflates inside the tank allowing the dust to fall from the inside walls of the filter so when the vac is turned on again, it helps to increase the air flow. The average number of sweeps per bag is about 8-10 jobs before the filter needs to be replaced. Some sweeps get more use depending on the job. When using this disposable bag, remove the drop in reusable micro bag filter that comes with each vac and use with the HEPA filter. These bags prevent most dust from getting into the tank or on the HEPA Filter, and they also make cleaning your vac fast and easy, while simultaneously increasing air flow.
