Powr-Flite Comfort Pro 6 Qt. HEPA Backpack Vacuum Bags, 10 Pack

Ten HEPA-media bags sized for the Powr-Flite Comfort Pro 6 quart backpack, sold as part X9739. HEPA media at the bag itself means the fine dust that would otherwise ride the exhaust air back into the room stays trapped in the bag, which matters most when the vacuum runs for hours at a stretch through an occupied space such as an office floor or a classroom being cleaned after hours.

The bag fits the BP6S and BP6P backpacks in the Comfort Pro line. A bag left to run well past its limit does not only cost suction gradually, it starts working against its own seal at the collar, so the habit worth building is watching the fill level rather than waiting for the machine to feel weak. A bag that has gone past its limit also puts more load on the motor, since the fan has to work harder to pull air through a restricted path, and that added strain is what shortens motor life over a season of daily use.

Swap the bag once it sits around three-quarters full, sooner if the operator notices the machine breathing harder against the shoulder straps or if the exhaust starts carrying a faint dusty smell. A backpack worked daily goes through bags fast enough that a full box on the shelf, rather than a single spare tucked in a supply closet, is what saves a mid-shift stop. Handle a fresh bag by its collar rather than by the media when loading it, since a seam torn on the way in undoes the whole reason for buying HEPA media in the first place.

Before ordering, confirm which Comfort Pro backpack is on the machine, since Powr-Flite sells more than one capacity in the same body style and a bag sized for the wrong quart rating will not seal at the collar even if it looks close enough by eye.
