Central vacuum bags get forgotten because the canister lives in a garage or basement where nobody looks at it. The result is a system that has quietly lost half its suction at every inlet in the house. These are 9-gallon paper bags for Filtex and compatible central vacuum units, four to a pack - roughly a year of changes for most households.
Built for
Homeowners and property managers maintaining a Filtex, AirVac, M&S, Brute, Star, D&R or Central Vac International central vacuum system.
Use Cases
- Annual or semi-annual bag change on a central vacuum canister
- Restoring suction that has faded at every inlet in the house
- Keeping fine dust off the power unit motor and filter
- Stocking a year of bags at once so the change actually gets done
Measuring before you buy
Central vacuum bags are sold by brand, but they fit by dimension, and the brand on the canister is often not the brand that made the power unit. Take the old bag out and measure it: this one is 13.5 inches across the collar and about 15.75 inches deep, at 9-gallon capacity. Filtex also used a 12-gallon bag that looks similar at a glance and will not seat properly in a 9-gallon unit.
Making the change interval stick
The practical problem with central vacuum maintenance is not difficulty, it is that the canister lives somewhere nobody walks past. The fix most people land on is tying the change to something already on the calendar - a season change, a filter change on the furnace - and keeping the spare bags physically next to the unit rather than in a supply closet upstairs. A four-pack stored at the canister is roughly a year of changes and removes the last excuse for skipping one.

Frequently asked questions
How do I confirm this is the right size for my unit?
Measure the old bag: this one is 9-gallon capacity, 13.5 inches across the mouth, and about 15.75 inches deep with a cardboard collar. The 12-gallon Filtex bag is a different part, so measure rather than going by brand alone.
Which brands besides Filtex do these fit?
The same 9-gallon 13.5-inch format is used by AirVac, M and S, Brute, Star, D and R, and Central Vac International power units. If your canister takes a 13.5-inch collared paper bag, this is very likely the one.
How often should a central vacuum bag be changed?
Two to four times a year for a typical household, and more often with pets, remodeling dust, or a large house. Suction falling off at the inlets is the practical signal - by then the bag has usually been full for a while.
Do I still need to clean the filter if I change the bag?
Yes. The bag is the first stage; the unit's filter is the backstop. Check it whenever you change the bag, because a clogged filter chokes airflow even with a brand new bag installed.
