Vacuum Cleaner Bag Types

Alphabet

Not sure what "Type G" means when it's written on a vacuum bag? It may not be immediately obvious, but these letter types are actually used to determine the right replacement bags for your vacuum cleaner.

Vacuum bags have letter types ranging from A-Z. These letters match vacuum bags to the style of vacuums they fit, whether it be upright, canister and cylinder or hand-held. The most common types are C, D, E, F, G, J, K and U.

What does my letter mean?

 

UPRIGHT VACUUMS

  • Brushroll dislodges dirt and dust in the carpet
  • Suction fan draws dirty air over the fan, into the vacuum bag
  • Dirt and dust is trapped and settles in dust bag
  • Clean air passes through the twin surfaces of the bag, which acts as a filter

CANISTER and CYLINDER VACUUMS

  • Dirt and dust are drawn up from the cleaning head through the hose
  • Unlike uprights, the dirty air enters the dust bag first
  • Air passes through the porous material of the dust bag, depositing dirt

HAND-HELD VACUUMS

  • Typically "straight suction" machines - whatever you vacuum goes directly into the bag
  • As with other types, clean air passes through the bag, leaving dirt inside
  • Smaller capacity means bags may need to be changed more frequently
  • More recent hand-held models are often bagless

Many vacuum cleaners come with features that indicate when your cleaner's dust bags need changing. Often this is an indicator light which is lit when the bag approaches a certain fill level, but there may also be fill lines or other clues on the bag itself. Changing your vacuum bag before it's completely full may improve performance, because it increases air flow without forcing the vacuum to work too hard.

Whenever possible, eSpares recommends using the genuine branded bags for your particular vacuum cleaner model. Using non-genuine bags may void your warranty, so be sure to check your user manual. However, if your vacuum bags have been discontinued, you can often find compatible vacuum bag spares to fit your machine's needs.
