How to confirm it's your model
Find the vacuum's rating plate: it's usually on the bottom or under the bag compartment lid. It shows the exact model. If it matches the Miele S400i or one of its variants (S400i–S456i, S410i, S420i, S430i, S440i, S456i), these bags will fit.
Tip: if you still have a used bag, check the cardboard collar. If it says GN, you're on the right track.
How to change the bag on the Miele S400i
- Unplug the vacuum and open the bag compartment lid.
- Pull the used bag out by its cardboard collar and seal it with the hygiene tab if it has one.
- Slide the new bag into the guide all the way, with the collar seated firmly on the intake.
- Unfold the bag inside the compartment so it isn't creased, then close the lid. If the lid won't close, the bag isn't seated correctly.
- Every 4 or 5 bags, check or replace the motor filter.
How often should you change the bag?
In a typical home, every 4–8 weeks. Change it sooner if the full-bag indicator turns red, suction drops, or it starts to smell. Don't wait until it's bursting: above 75% full, suction drops sharply.

Frequently asked questions
What bag does the Miele S400i take?
The Miele S400i uses Miele GN HyClean 3D bags. The genuine part number is GN (also listed as 10123210, 9917730, 10408410, G/N). Compatible bags that list that part number or the model in the title also fit.
Do compatible bags work in the Miele S400i?
Yes. Good-quality compatible bags have the same cardboard collar and are usually multi-layer microfiber, which filters as well as or better than the original paper. Pick packs with lots of reviews that list part number GN.
How often should you change the bag on the Miele S400i?
In a typical home, every 4–8 weeks. Change it sooner if the full-bag indicator turns red, suction drops, or it starts to smell. Don't wait until it's bursting: above 75% full, suction drops sharply.
Can I empty and reuse the Miele S400i bag?
No. Paper and microfiber bags are disposable: emptying them damages the filter pores, and fine dust goes back into the air and the motor. A new bag is cheap and protects your vacuum.
