These replacement vacuum bags are close collared which means they can only be used once, capturing the maximum amount of dirt to fill up the bag, and then they need to be properly disposed of. Having a closed collared bag ensures dust and dirt particles stay inside the bag. If the bag becomes compromised by being torn or punctured, replace the bag immediately. These allergen filtration bags capture a wide range of airborne particles, including pollen, cat fur, spores, and other allergens. The bags are designed for use with the
Hoover® HVRPWR™ backpack vacuum (#CH93619), and the previous MPWR™ versions of the battery powered backpack vacuum.
