How we compared Blueair 211i Max replacement filters
The best Blueair 211i Max replacement filter depends first on exact fit, then on whether you need the main filter, a washable pre-filter or a carbon option. We compared the stated model compatibility, filter type, pack contents and replacement guidance.
We gave the highest score to the washable genuine pre-filter because it is reusable and designed for this model, followed closely by the genuine main filter. Compatible filters score well when they state the fit and offer useful carbon or multi-pack options, but model exclusions and different replacement intervals matter.
Our score weighs specs, features and buyer feedback against what you’re shopping for.

BLUEAIR genuine washable pre-filter: Best for washable pre-filter care
BLUEAIR Genuine 211i Max Air Purifier Washable: Best for washable pre-filter care
- Removable, washable fabric pre-filter
- Captures large particles
- Made for Blue Pure 211i Max
- Not compatible with 211+ and 211+ Auto
This genuine fabric pre-filter is removable and washable, so you can clean it and reuse it. It captures larger particles such as dust, pollen and pet hair.
Pros
- Washable and reusable
- Captures large particles
- Available in Fog Grey
Cons
- Pre-filter, not the main replacement filter
- Not compatible with 211+ and 211+ Auto
The Fog Grey fabric pre-filter is a washable, reusable part for the Blue Pure 211i Max. It catches larger particles such as dust, lint, pollen and pet hair, which can help extend the life of the primary filter.
Blueair says you can vacuum the fabric exterior as often as needed. For a deeper clean, the brand recommends a gentle, low-temperature machine cycle followed by hang drying.
This is not the main replacement filter. Choose it when you need the outer fabric pre-filter, and confirm your purifier is a 211i Max because the part is not compatible with the 211+ or 211+ Auto.
BLUEAIR genuine main filter: Best for genuine main-filter replacement
BLUEAIR Genuine Blue Pure 211i Max Air: Best for genuine main-filter replacement

- Not compatible with 211+ and 211+ Auto
The genuine Blueair replacement filter is made for the Blue Pure 211i Max and uses a slide-in mount. It is the most direct choice if you want a genuine main filter for the exact model.
Blueair describes an activated carbon component for light household odors from cooking, pets and smoking. The brand’s filter information also gives a replacement timing window within 9 months, based on usage patterns and pollution levels.
Do not confuse this with the washable fabric pre-filter above. The genuine main filter is the primary replacement part, while the pre-filter is a washable outer component.
Leemone SmokeBlock: Best for a compatible carbon 2-pack
Leemone F2MAX SmokeBlock Filter for Blueair Blue: Best for a compatible carbon 2-pack
- Compatible with Blue Pure 211i Max
- Two filters in the pack

Pros
- Two filters per pack

- Model compatibility is stated
Cons

Leemone’s F2MAX SmokeBlock option is a two-filter compatible pack for the Blue Pure 211i Max. Its particle and activated carbon media are intended to address airborne particles and household odors.
Leemone recommends replacement within 9 months based on actual usage. That is a useful interval to compare with your household’s filter use and the genuine option’s timing guidance.
This is not specified for the 211+ or 211+ Auto. Check the model number on your purifier before ordering, particularly if you have more than one Blueair unit at home.

Pros
- Two filters per pack
- Carbon for cooking, smoking and pet odors
- Shorter replacement interval is stated
Cons
- Compatible third-party filter
- Replacement timing may mean more frequent changes
Selfgurher’s compatible two-pack combines particle filtration with activated carbon for odors from smoking, pets and cooking fumes. It is specified for the Blue Pure 211i Max, so verify that model before choosing it.
The brand recommends replacing the filter within 6 months based on actual use. That is a shorter interval than the 9-month guidance on some other options, which can affect how often you need to keep a spare on hand.
Pick it if a shorter stated interval fits your filter-care routine. If you want fewer scheduled changes, compare the replacement guidance from the other options before deciding.
Mbetter two-pack: Best for a two-filter carbon option
Mbetter 2 Pack 211i Max Filters Replacement: Best for a two-filter carbon option
- Compatible with Blue Pure 211i Max

- Confirm the purifier model carefully
Mbetter’s compatible two-pack includes pleated filter material and activated carbon. It is specified for the Blue Pure 211i Max, with explicit exclusions for several other Blueair models, including the 311i Max and Mini Max.
Mbetter recommends replacement within 9 months based on actual use. Its product information also describes an unfolded round filter shape, so review fit details and your purifier model carefully before ordering.
This option may suit you if you want two filters in one pack and odor filtration. It is a compatible third-party choice, so compare it with the genuine filter if brand matching is your priority.
NABEECA two-pack: Best for a 6–8 month change range
NABEECA 2-Pack 211i Max Replacement Filter Compatible: Best for a 6–8 month change range
- Compatible with Blueair Blue Pure 211i Max
- Two filters in the pack
- HEPA and activated carbon media
- Suggested replacement every 6–8 months
NABEECA offers a compatible two-pack with HEPA and activated carbon media. Its guidance recommends changing the filter every 6–8 months.
Pros
- Two filters per pack
- Carbon for light household odors
- Replacement range is stated
Cons
- Compatible third-party filter
- Verify fit and replacement timing for your use
NABEECA’s compatible two-pack is specified for the Blueair Blue Pure 211i Max and combines HEPA and activated carbon media. The brand recommends replacement every 6–8 months.
The fit notice excludes a range of other models, including 211+, 411i Max, 511 and 311 units. Confirm the purifier’s full model name before choosing this pack.
Its stated interval falls between the 6-month guidance on Selfgurher and the 9-month guidance on some other options. Consider the interval alongside the pack size and carbon feature when comparing ongoing filter needs.
What should you check before buying a 211i Max filter?
Check the full purifier model and whether you need the main filter or the washable fabric pre-filter. Model names across the Blueair range are similar, but the compatibility notices here rule out several other units.
The genuine Blueair main filter is a straightforward fit choice for the Blue Pure 211i Max. Compatible filters can add a two-pack and activated carbon, but read the model exclusions closely.
How does replacement timing affect ongoing filter costs?
Replacement timing and pack size shape how often you need to buy filters. Some options recommend replacement within 6 months, others every 6–8 months, and some within 9 months, all based on use.
A two-pack gives you a spare filter, but it does not by itself guarantee a lower cost over time. Compare the current price per filter and the maker’s replacement guidance when you shop.
Which 211i Max filter helps with household odors?
Choose a filter with activated carbon if odor filtration is part of your priority. The genuine Blueair main filter and the compatible Leemone, Selfgurher, Mbetter and NABEECA options all describe carbon media or a carbon component.
The washable pre-filter serves a different role: it catches larger particles and can be cleaned and reused. It is not the main filter or the carbon choice in this group.
Which Blueair 211i Max replacement filter should you choose?
Choose the genuine Blueair main filter for a model-specific primary replacement, the washable fabric pre-filter for reusable outer-filter care, or a compatible two-pack if carbon media and a spare matter more. Compare the stated change interval and exclusions before you buy.

Frequently asked questions
Which filter fits the Blueair 211i Max?
The genuine Blueair main replacement filter and the compatible filters here are made for the Blue Pure 211i Max. Check your purifier’s model before ordering, because several options specifically exclude the 211+ and 211+ Auto.
The washable Blueair fabric pre-filter is a separate part, not a replacement for the main filter.
Do 211i Max replacement filters help with odors?
Several options here include activated carbon, which is intended to help with household odors from cooking, pets or smoke. Blueair describes its genuine filter’s carbon component as handling light household odors.
Odor results depend on the source and use, so avoid treating carbon as a guarantee of odor removal.
How often should you replace a 211i Max filter?
Replacement guidance varies by filter. Blueair’s genuine filter description gives a replacement timing window of up to 9 months, while compatible options recommend periods ranging from 6 to 9 months or 6–8 months.
Follow the guidance for the filter you choose and account for actual use.
Is the washable Blueair pre-filter the main filter?
No. The Fog Grey washable fabric part is a pre-filter that captures larger particles such as dust, pollen and pet hair.
It is removable, can be vacuumed, and can be washed gently when it needs a deeper clean.
The main replacement filter is a separate component.
Can a 211i Max filter fit a Blueair 211+?
The filters in this guide are specified for the Blue Pure 211i Max, and several explicitly say they do not fit the 211+ or 211+ Auto. Check your exact purifier model before buying.
A similar model name does not confirm that the filter will fit.
