There are a variety of bag styles available for most of the bagged vacuums on the market. While HEPA bags are ideal for allergy and asthma sufferers, there are also other more standard (and cheaper) bags available for applications where the heavy-duty HEPA system isn’t necessary. Most bags come with a paper outer lining, and this helps to keep prices and bag weight down. For heavy-duty applications, there are cloth bags available that can help provide an added few layers of protection from any sharp or heavy objects that may pass through the suction system.
