Find your vacuum in the table below, or read the type letters off your old bag box. Every row links to the genuine Miele pack we sell for that type, and our Miele bags page has every pack size in one place. Already know your type? Go straight to GN, FJM, CO, TU or U bags.
Find your Miele bag by model
| If your Miele is a… | Bag type | Genuine pack |
|---|---|---|
| Classic C1, Complete C2, Complete C3, S8, S5 or S2 | GN | GN HyClean Air, 4 bags |
| Complete C1, Compact C1, Compact C2, S6 or S4 | FJM | FJM AirClean 3D, 4 bags |
| Guard M1 (every version) | CO | CO HyClean Air, 4 bags |
| Guard L1 or Guard S1 | TU | TU HyClean Air, 4 bags |
| Dynamic U1 or S7 upright | U | U AirClean 3D, 4 bags |
| Swing H1 or S1 | KK | KK AirClean 3D, 5 bags |
| Blizzard CX1, Boost CX1 or a Triflex cordless | No bags | Miele filters |
The model lists come from Miele's own pages for the GN, FJM, CO and TU packs and its product sheets for U and KK. The Blizzard CX1 and Boost CX1 are bagless canisters, so they need filters, not bags.
Where to find the type on your own vacuum
You don't need the model name if you have the old bag. Three places tell you the type:
- The bag box. The type letters are printed on the front, as on the GN and FJM boxes pictured below.
- The plate on the bag's collar. Miele UK says the bag's holding plate is color-coordinated with the mounting plate inside the vacuum: blue for GN, red for FJM, brown for CO, turquoise for TU, green for U and yellow for KK.
- The model label. If the old bag is gone, look for the model name on the bottom of the vacuum body and use the table above.
GN or FJM? The pair people mix up most
GN and FJM bags fit different bag chambers and have different collars. A GN bag will not seal in an FJM machine, and the reverse is also true. A bag that doesn't seal lets dust past it and into the motor protection filter, which costs you suction.
The trap is the Complete series. Miele lists the Complete C1 for FJM bags but the Complete C2 and Complete C3 for GN. Same family name, different bag. If your vacuum says Complete, read the number before you order.
HyClean vs AirClean: what's the difference?
They are two lines of Miele bags. The type letters still decide the fit; the line describes the bag itself. Here is how Miele describes each on its U.S. pages:
| AirClean 3D (example: FJM) | HyClean Air (example: GN) | |
|---|---|---|
| Filtration claim | Filters out more than 99.9% of all fine dust particles | 99.99% with Miele's AirClean filter system, measured to IEC 62885-2 |
| Closing the bag | Automatic bag closure for a clean change | HyClose self-sealing collar |
| Other points Miele lists | Uses the full bag capacity | "Exceptional service life" from its 3D design; 70% recycled material |
| In the box | 4 bags, 1 motor protection filter and 1 exhaust filter | |
Two practical points. First, if your vacuum takes FJM, both lines fit: we carry FJM in AirClean 3D and HyClean Air. GN, CO and TU packs come in the HyClean line. Second, don't let the Guard spec sheets confuse you. They name the bag "HyClean Pure CO" or "HyClean Pure TU", and the replacement packs Miele sells for those machines are the HyClean Air CO and TU packs in the table above. Miele says its CO pack is suitable for all Guard M1 models.
Which pack: 4 bags, XL, Allergy XL or Performance?
Same bag, different quantities and extras. We stock these sizes for GN, CO and TU:
- 4-bag pack: the standard box, with its replacement filters.
- XL pack: 8 bags plus extra filters, for homes that change bags often.
- Allergy XL and Performance packs: 8 or 16 bags with a HEPA exhaust filter instead of the standard one.
One catch for Classic C1 owners: Miele lists the GN Allergy XL and Performance packs for the Complete C2 and Complete C3 only. On a Classic C1, buy the regular GN bags and, if you want HEPA, add the separate SF-HA 30 HEPA AirClean filter.
When to change the bag, and the filters that come with it
Change the bag when the indicator shows full or suction drops. Fine powder can fool the indicator: Miele's operating instructions say plaster dust or flour can make it read full before the bag looks full. The same instructions say never to vacuum ashes, even ones that look cold. If your indicator says full on a bag that looks half empty, see why a bag indicator can read full early.
Each new box also brings fresh filters. Miele's instructions for one of its GN canister models say to replace the motor protection filter and the standard AirClean exhaust filter from the box each time you start a new box. The optional HEPA AirClean exhaust filter lasts longer: Miele puts it at about 50 operating hours, which it equates to roughly a year of average use. Bagless Boost CX1 owners have a different filter, the SF-HA 60, which has a TimeStrip indicator, and Miele says to change it once a year. Our guide to checking Miele filter fit covers the rest.
Can I use generic bags in a Miele?
We don't recommend it, and neither does Miele. Its operating instructions say genuine Miele FilterBags are not made of paper and do not have a cardboard collar, and that faults caused by accessories without the Miele logo are not covered by the vacuum's warranty. A collar that doesn't seal sends fine dust past the bag to the motor protection filter, and that is where suction goes first.
Miele bag questions
Do all Miele vacuums use the same bags?
No. Miele uses six bag types: GN, FJM, CO, TU, U and KK. Each fits a different group of machines, and the bagless Blizzard CX1, Boost CX1 and Triflex models take no bags at all.
Are Miele GN and FJM bags interchangeable?
No. They fit different bag chambers and have different collars. The Complete C1 takes FJM, while the Complete C2 and C3 take GN.
Is HyClean better than AirClean?
They are two Miele bag lines. Miele rates its HyClean Air bags at 99.99% with the AirClean filter system and gives them a self-sealing HyClose collar; it describes AirClean 3D bags as filtering out more than 99.9% of fine dust. Both fit only the bag type printed on the box.
What bags does a Miele Guard M1 take?
CO bags. Miele says its HyClean Air CO pack suits every Guard M1 model. The Guard L1 and Guard S1 take TU bags instead.
