GN, FJM, CO, TU, U or KK? Match your Miele to the right genuine bag in one lookup table — from the family-owned Avon, CT shop that stocks them all.
Avon Vacuums | June 4, 2026
Every week someone walks into our Avon shop holding a phone photo of the underside of a Miele canister, asking the same question: "Which bags does this thing take?" Usually they've already bought the wrong box once — or worse, a generic knockoff that collapsed inside the bag compartment of a $900 vacuum.
Miele makes it harder than it needs to be. Six bag types, two product lines (the older AirClean 3D and the newer HyClean Air), and letter codes — GN, FJM, CO, TU, U, KK — that mean nothing until someone translates them. So let's translate them.
The letter code on your Miele bag isn't marketing — it's the size and shape of the bag collar. Match the code to your machine and the bag seals perfectly. Guess wrong and you lose suction, leak dust, or jam the compartment. Find your code once, and you'll never buy the wrong box again.
First: AirClean 3D or HyClean Air?
Miele is mid-transition between two bag generations. AirClean 3D is the line you've bought for the last decade. HyClean Air is its replacement — same letter codes, improved airflow as the bag fills. They're cross-compatible: a HyClean Air GN fits every vacuum an AirClean GN fits. After fifty years on the service bench, our advice is simple — buy whichever genuine box is on the shelf and don't overthink the generation. The letter code is the part that matters.
The Lookup Table
Find your vacuum, buy that code:
| Your Miele | Bag code | Get it here |
|---|---|---|
| Classic C1, Complete C2, Complete C3 (and older S2/S5/S8) | GN | GN 4-pack · 8-pack · Allergy pack + HEPA |
| Compact C1, Compact C2 (and older S4/S6) | FJM | FJM 8-pack · AirClean 3D 4-pack |
| Guard M1 canisters (Miele's newest line) | CO (red collar) | CO 4-pack · 8-pack + filters |
| Guard L1 & S1 | TU | TU 4-pack · 8-pack |
| Dynamic U1 uprights (and S7) | U | Type U 4-pack · 16 bags + HEPA |
| Quickstep & Swing H1 stick vacuums | KK | KK 4-pack |
The Allergy Packs Are the Quiet Bargain
Your Miele needs a fresh HEPA filter roughly once a year — and a new filter sold alone costs more than the upgrade price inside an Allergy or Performance pack. If you're due for a filter anyway, the GN Allergy pack or the 16-bag Performance pack is the better buy. We'll tell you the same thing at the counter, even though it means selling you fewer boxes.
Why Genuine Bags — From the People Who Fix the Vacuums
We see this every week: a Miele comes in "losing suction," and inside is a generic bag with a collapsed collar leaking fine dust straight into the motor compartment. Genuine Miele bags are a three-layer filtration stage, not a dust sack — and Miele excludes damage from non-genuine parts from warranty coverage. The $5 you save on a knockoff box is the most expensive $5 in floor care.
