Which Miele Vacuum Bag Do I Need? FJM vs GN vs U

Which Miele Vacuum Bag Do I Need? FJM vs GN vs U

When our customers require Miele vacuum bags, they often ask the same question, which bag is the right fit for their Miele vacuum cleaner?

Using a Miele vacuum with a dust bag is an ideal choice for individuals who suffer from allergies. The bags prevent dirt, dust, and other particles from being released back into the air while the vacuum is running or during bag changes. This is particularly important for families with infants.

To ensure your vacuum continues to perform efficiently, it's crucial to change the bags regularly. This guide provides information on which Miele vacuum bags fit specific vacuum models and highlights the distinctions between them. We'll also offer guidance on purchasing the appropriate bags and outline when and how to replace them.

When it comes to selecting the correct Miele vacuum bag, it's important to note that their product line has evolved over time. As a result, it's essential to exercise caution when purchasing new supplies of vacuum bags and filters.

The type of Miele vacuum cleaner bag that you require is determined by the model of your vacuum. Larger GN bags are needed for some canister vacuums that have bigger bodies, while FJM bags are typically used for smaller, entry-level canisters. Stick and upright vacuums, on the other hand, require more slender bags.

Additionally, you have the option of creating a custom vacuum system by mixing and matching filters and bags. For example, if you don't suffer from allergies, you may not need to purchase replacement HEPA filters.


Miele offers four different sizes of vacuum bags in the market, including GN, FJM, U, and KK. To make it easier to identify which type of bag is suitable for your vacuum, Miele color-coded them for convenience.

When it comes to Miele canister vacuums, they can use either FJM (Red tab) or GN dustbags (Blue tab).  

For Miele upright vacuums, U dustbags are the appropriate choice, while KK bags are compatible with Miele upright/stick vacuums.

It's common to become confused when searching for Miele canister vacuum bags, particularly with the GN (Blue tab) and FJM bags (Red tab), which are quite similar. The only distinguishing feature between these bags is their size and tab colour.

Miele GN vacuum bags are designed for larger canister vacuums like the Classic C1 and Complete C2 & C3 Series, and have a capacity of 4.76 quarts.

In contrast, Miele FJM vacuum bags are smaller and have a 3.7 quart capacity. These bags are intended for smaller canister vacuums like the Complete C1, Compact C1, and C2 Series.

Despite their size differences, all of these bags have the same fitting. So, if you mistakenly purchase the wrong ones, the only variation will be how much dust and debris each bag can hold.


Miele Vacuum Bags Work as A Filter Too!

Did you ever notice a bad odor coming out of your vacuum as you cleaned? If you are using a Miele vacuum, this is not the case. Miele vacuum bags have a thick, multilayer, cloth-like texture that serves as an initial filter. This ensures that the dust and debris you vacuum up stays trapped inside the bag.

As the dirt and debris are sucked into the Miele vacuum, they go straight into the bag, where they get tightly sealed. These bags are so powerful that they capture over 99.9 percent of all dust particles. The air then moves into the motor, which is protected by a motor cleaner filter. This filter should be changed every four bags and is included in all Miele vacuum bag packages. Finally, the air moves through a HEPA, charcoal, or standard clean air filter.

Miele vacuums are well-known for their high-quality filtration, setting them apart from the competition. If you or your family members suffer from allergies or you have an infant in the house, you'll appreciate that the air emitted by Miele canister vacuums is cleaner than the air they pull in.

You'll also be happy to know that there's no need to clean out a reusable dust bin as the vacuum bag keeps the interior of your vacuum clean.

How to Change the Bag on Your Miele Vacum Cleaner

Replacing the bag on your Miele vacuum cleaner may seem daunting, but it's actually quite simple. Follow these steps to get it done:

  1. Remove the full bag. Locate the dust compartment lid release button and lift it until it clicks. This will open up the compartment where the bag is housed. Gently grip the plastic collar of the filter bag and pull to remove it. Don't worry about allergens - Miele vacuum bags are designed with a special flap that seals the top and prevents any dust or debris from escaping.


  2. Place the new vacuum bag into the blue holder by aligning the collar with the holder and pressing it in as far as it will go. Be careful not to unfold the bag when removing it from its box. Only unfold it when it is properly situated in the holder.


  3. Secure the new vacuum bag in place by closing the dust compartment lid and pressing down until it clicks into place.

How Long will the Miele Vacuum Bags Last?

The lifespan of a Miele vacuum cleaner bag typically lasts for about three months with regular usage, but this can differ based on factors like your home's size and the frequency of vacuuming. For larger homes or those with wall-to-wall carpets, it's recommended to replace the bag once a month to ensure optimal performance.

How Do I know when My Miele Vacuum Bags are Full?

Fortunately, Miele simplifies the process of determining if your vacuum bag needs to be changed. Look for a small window with an indicator light located on top of your vacuum's bag door. Once the Miele vacuum bag full indicator turns red, you will know that it is time to replace the bag.

Frequntly Asked Miele Questions

1. What is that bad smell coming from my Miele vacuum Cleaner?

Miele vacuums are equipped with robust filters that effectively capture and contain odors. However, it's not uncommon for vacuums to emit a slight odor during use. If you detect a strong smell emanating from your Miele vacuum, it could indicate that it's time to replace the vacuum bag or filter, clean the vacuum hose, or seek professional servicing.

2. Are these miele Vacuum Cleaner Bags Hepa?

Miele vacuum bags are not HEPA certified, but this is because vacuum bags cannot obtain HEPA certification. HEPA stands for "high-efficiency particulate air" and pertains to air filters rather than vacuum bags. Nonetheless, Miele produces a HEPA filter that can be utilized in their vacuums to alleviate allergy symptoms.

3. Can you tell me the difference between AirClean and HyClean Miele Vacuum Bags?

Miele's HyClean and AirClean bags are akin, but they are not the same and cannot be swapped interchangeably. The HyClean bag, which is no longer in production and not intended for U.S. models, features strips that prevent tearing or ripping. In contrast, the AirClean bags are specifically engineered to perform optimally in the vacuum and to store dust and debris effectively, without rapidly filling or causing spills.

4. Is there Fibreglass in Miele Vacuum Cleaner Bags?

There has been a recent apprehension regarding vacuum bags, specifically those with HEPA filters, containing fiberglass fibers. However, this is not a concern with Miele vacuums as their bags have never contained any fiberglass.

5. Which Miele Vacuum Cleaner Filter should I use?

Miele produces a distinct series of replacement filters for each model of their vacuum cleaners. To determine the filter required for your particular model, the most effective approach is to consult your user manual.

6. Should I use a special Miele Vacuum Filter if I have Pets?

Miele's extensive selection of replacement filters, including high-performance options specifically formulated for pet owners, is a significant factor in the brand's popularity as a vacuum manufacturer. The Miele charcoal filter is ideal for combating stubborn pet-related odors, whereas their HEPA filters are effective in eliminating allergens and minimizing symptoms caused by pet dander and saliva.

7. Is it Possible to clean A Miele Vacuum Cleaner Hepa Filter?

Unless specified in your user manual, it is not recommended to immerse a HEPA filter in water. However, this does not imply that cleaning is prohibited. The optimal technique for cleaning a Miele HEPA filter involves detaching it from the vacuum and gently wiping it with a dry cloth. If the dust or debris is difficult to remove, the miniature attachments on your vacuum can be used to clean it effectively.

8. How often should I change my Miele Hepa Filter?

Because the HEPA filter removes allergens and debris from your home, it is critical to ensure that it is functioning at maximum efficiency. As a result, it is recommended to replace your Miele HEPA filter on an annual basis, although you may need to do so more frequently depending on how often you vacuum and the condition of the area being cleaned.

9. How do I change the Filter in my Miele Vacuum Cleaner?

Replacing the filter in your Miele vacuum cleaner is comparable to replacing the vacuum bag. First, open the compartment where the vacuum bag is located, and gently detach the existing filter from its holder, which is typically positioned in the top left corner of the compartment.

Installation is equally straightforward: simply align the new filter correctly and slide it into place. This same method can also be used to clean and re-install the current filter.

10. How do I activate the miele Hepa Filter?

When inserting a new filter, it is necessary to activate it. To activate, with the compartment panel open, press the green button located on the front side of the filter.

11. Do all Miele Vacuum Cleaners use Hepa Filters?

While not all Miele vacuums come equipped with HEPA filters, certified HEPA filters can be purchased separately and utilized with your vacuum.

However, the majority of Miele vacuums feature a sealed system, which effectively prevents the dispersal of dust into the air during the vacuuming process.

12. Do the Cordless Miele Vacuum Cleaners have filters that need changing?

Although the Miele Triflex cordless vacuum is more convenient to use when cleaning your home, its care is comparable to other models. As a result, it is necessary to change the filter every three months or so, similar to a corded Miele vacuum.

13. Can I wash my Cordless Vacuum Cleaner Miele filter?

As per Miele's guidelines, the filter should not be washed but can be cleaned. To clean it, remove the cover to access and eliminate any trapped dirt or debris. Once completed, securely replace the cover.

To achieve a more comprehensive clean, you may use a slightly damp cloth to wipe your vacuum and vacuum accessories, followed by a dry cloth.
