Four-ply paper replacement bags for Electrolux Style U upright vacuums, sold twelve to a package. This is the bag the Discovery II and its relatives were designed around, and keeping a pack on the shelf is what stops a good machine from spending a week limping along on a full one. Cleaning contractors, facility housekeeping teams and households running any post-1986 Electrolux upright use these as a routine consumable.

- Buyers who want four-ply paper media rather than the thinnest bag that fits

Why four-ply is worth asking about
Bag media is doing two jobs at once, and they pull against each other: it has to hold the fine dust back and still let air through. Thin single-ply paper does the second job well and the first job poorly, which is how dust ends up downstream of the bag and eventually in the motor. Multiple plies give the bag more surface and more depth to trap particles without collapsing airflow as it loads, so the machine holds its suction further into the bag life and the dust that ought to be captured stays captured.
The practical habit that follows from that is simple: change at roughly two-thirds full. Waiting until a bag is packed costs you suction long before you notice it, and a starved motor draws more current and runs hotter than it should.
Frequently asked questions
How do I know my vacuum takes Style U bags?
Style U is the upright bag Electrolux has used since 1986 across the Discovery, Genesis, Prolux and Epic upright families. The quickest check is the bag already in the machine, which will be marked with its style letter. The model plate on the body of the vacuum will also identify the machine so you can confirm it against the fitment list.
How often should the bag be changed?
Change it when it is about two-thirds full rather than waiting for it to pack solid. A full bag chokes airflow, which costs you suction at the floor and makes the motor work harder and run hotter. In commercial use that often means weekly or more.
Can I shake out and reuse a paper bag?
No. Paper vacuum bags are single-use. The fine dust that gives them their filtration is embedded in the paper, and emptying one tears the media, releases what you just collected and leaves the vacuum filtering far worse than before.
Why use bags rather than running the vacuum bagless?
These machines were engineered around a bag as part of the filtration path. The bag is what captures fine dust and keeps it out of the motor and out of the air when you dispose of it, which matters most in facilities where allergens are a concern.
What does four-ply mean on a vacuum bag?
It refers to the layers of paper media the bag is built from. More plies give more depth to trap fine particles and help the bag keep passing air as it loads, rather than choking early the way a thin single-ply bag can.
