9 Best Blueair Air Purifier Filter Replacement (November 2026)
The best Blueair air purifier filter replacements include the BLUEAIR Genuine 411 Series Air Purifier Replacement for genuine 411 series fit, the WILERDA 2 Pack 311i Max Replacement Filter for 311i Max two-filter value, and the BLUEAIR Genuine 211+ Air Purifier Replacement Filter for genuine 211+ replacement.

- How do you install and care for a replacement filter?
- Which Blueair air purifier filter replacement should you choose?
The best Blueair air purifier filter replacement depends on your purifier series. The genuine BLUEAIR 411 filter is the strongest direct match for original 411 models, while WILERDA leads for the 311i Max and the genuine BLUEAIR 211+ filter leads for the non-auto 211+.
That series first approach keeps the choice simple and avoids returns. Each filter in this guide is tied to specific model names, so the purifier you own should narrow the list before you compare materials or pack size.
A model number is the first check because Blueair uses similar names across different generations. A filter for the original 411 may not fit the 411i Max, and a 311i Max filter may not fit the 311i+ Max.
Those close names are easy to miss in a quick search. Taking a minute to match the full label on the purifier, the manual or the filter housing can save time later.
For more context on a specific machine, read our Blueair 211i Max review or compare the Blueair 311i Max review before choosing a replacement.
Once the model is confirmed, the next questions are practical. Look at whether carbon is included for odors, how many filters are in the pack and what replacement interval the product states.

Which Blueair air purifier filter replacement is best?
The best overall choice is the BLUEAIR Genuine 411 Series replacement for owners of the original 411 family. It has the clearest model match, includes particle filtration and carbon mesh, and comes from the purifier brand.
Our score weighs compatibility, filter materials, pack size and buyer feedback against what you're shopping for. The scores are not a promise of filter life or purifier performance.
BLUEAIR Genuine 411 Series Air Purifier Replacement: Best for genuine 411 series fit
- Fits Blue Pure 411, 411 Auto and 411+
- Particle and activated carbon filtration
- 1 filter with carbon mesh
- Pleated polypropylene construction
This genuine BLUEAIR replacement is the clearest match for Blue Pure 411, 411 Auto and 411+ owners. Its particle filter and activated carbon mesh address both airborne particles and common household odors.
Pros
- Genuine BLUEAIR replacement
- Fits 3 stated 411 series models
- Particle and carbon filtration
Cons
- Only 1 filter
- Not for other Blueair series
The BLUEAIR Genuine 411 Series replacement is the safest pick when your purifier is a Blue Pure 411, 411 Auto or 411+. It includes 1 particle filter with carbon mesh, so it addresses both airborne particles and common household odors.
The particle side is aimed at everyday indoor particles such as dust and allergens. The carbon mesh adds a layer for odors, which makes it a broader daily choice than a particle only filter.
The pleated polypropylene construction is sized at 8 x 1.9 x 11.1 in. Pleats add surface area within a compact shape, and the stated size helps confirm that it matches the 411 housing.
The single-filter pack suits an owner who wants the direct replacement rather than several generic filters stored at home. It is a clean one-for-one swap when the current filter has reached the end of its stated life.
Blueair identifies this filter for the original 411 series only. That narrow compatibility is useful because it reduces guesswork, but it also means you should not use it as a general replacement for every compact Blueair purifier.
Choose this filter for the clearest genuine fit. If you own a 411 and want several replacements in one pack, compare it with the Smilyan option below.
WILERDA 2 Pack 311i Max Replacement Filter: Best for 311i Max two-filter value
- Fits Blue Pure 311i Max
- 2 filters included
- HEPA and activated carbon filter materials
- Pleated rectangular design
WILERDA gives 311i Max owners two replacement filters in one pack. Its compatibility is narrow, so confirm that your purifier is the 311i Max and not the 311i+ Max or another Blueair model.
Pros
- Two-filter pack
- Activated carbon layer
- Clear model-specific compatibility
Cons
- Not for 211+, 411i Max, 511 or 311i+ Max
- Generic replacement
WILERDA is the strongest choice for Blue Pure 311i Max owners who want 2 filters in one pack. Its pleated rectangular filter uses true HEPA and activated carbon filter materials.
The combination matters in daily use. HEPA style particle filtration handles dust, smoke particles and pet dander, while the activated carbon layer is aimed at common household odors from cooking, pets and smoke.
The stated dimensions are 11.4 x 3.7 x 17.7 in. That tall rectangular format is specific to the 311i Max housing, so size is another clue that this is not a general Blueair filter.
WILERDA identifies it for the Blue Pure 311i Max and Blue Pure F3-MAX, along with a BLUEAIR HEPASilent air cleaner. Check the model number on your purifier before ordering, since the listing is very explicit about fit.
The exclusions matter. This filter is not for the 211+, 411i Max, 411a max, 511, 311 or 311i+ Max.
The dedicated Blueair Blue Pure 311i+ Max review can help if your model name includes the plus sign.
Choose WILERDA when the model label says 311i Max. Its two-filter format is useful for keeping a spare available, but the model warning makes careful matching essential.
BLUEAIR Genuine 211+ Air Purifier Replacement Filter: Best for genuine 211+ replacement
- Designed for Blue Pure 211+
- Particle filter with carbon mesh
- 1 filter included
- Carbon fiber material
This genuine BLUEAIR filter is for the Blue Pure 211+ non-auto model. It combines particle filtration with a carbon mesh layer in a single replacement filter.
Pros
- Genuine BLUEAIR replacement
- Carbon mesh included
- Made for Blue Pure 211+
Cons
- Single-filter pack
- Model match must be exact
The genuine BLUEAIR 211+ replacement is the best direct match for the Blue Pure 211+ non-auto model. It includes 1 particle filter with carbon mesh and uses carbon fiber material.
The dual design suits a home where both particles and odors are part of the concern. Particle filtration addresses dust, pollen and pet dander, while carbon mesh is included for household odors and smoke.
Its dimensions are 20.35 x 2.76 x 11.69 in. That large format fits the 211+ housing and helps distinguish it from smaller compact series filters at a glance.
The single-filter pack is straightforward for owners replacing one used filter at a time. There is no spare in the box, so some owners may want to order ahead if a spare is useful.
This choice is different from a filter marked for 211+ Auto. If your purifier is the Auto model, compare the MGCADI option instead of assuming the genuine 211+ filter covers both versions.
Choose this filter when genuine BLUEAIR compatibility for the standard 211+ matters most. It is less suitable when you need a two-pack or have the Auto version.
isinlive Mini Max Replacement Filter for Blueair: Best for Mini Max two-filter supply
- Fits Blue Pure Mini Max and Mini Max Auto
- 2 filters included
- Main filter and activated carbon
- MERV 13 rating
isinlive is the dedicated choice for Blueair Mini Max and Mini Max Auto owners. The two-pack uses a main filter with activated carbon and has a MERV 13 rating.
Pros
- Two-filter pack
- Fits Mini Max models
- Activated carbon included
Cons
- Only for Mini Max models
- Generic replacement
isinlive fits the Blue Pure Mini Max and Mini Max Auto. It includes 2 filters, with a main filter and activated carbon in a 2-in-1 design.
That design covers the two main jobs in a compact purifier. The main filter captures airborne particles such as dust, pet dander and pollen, while activated carbon helps with household odors from smoking, cooking and pets.
The filter has a MERV 13 rating and a pleated rectangular construction. The rating gives a plain clue about particle capture level, and pleating helps pack more filter area into a small housing.
Its stated dimensions are 8.9 x 8.9 x 5.9 in, and the package includes two Mini Max filters. The square shape is a useful visual check against other Blueair series.
The compatibility note is narrow. It is not for other Blueair models, so match the Mini Max name on your purifier before choosing it.
This is the practical pick for Mini Max owners who want a spare without buying another single-filter pack. It does not help owners of the original 411 or 411i Max.
Smilyan Blue Pure Filter Replacement for Blueair: Best for a larger 411 replacement pack
- Fits Blue Pure 411, 411+ and 411 Auto
- 3 filters included
- Particle and activated carbon filtration
- Fine pre-filter
Smilyan gives owners of the original 411 family three replacement filters. It includes particle filtration, activated carbon and a fine pre-filter, but it is not compatible with the 411i Max.
Pros
- Three-filter pack
- Fits 411 family models
- Activated carbon and pre-filter
Cons
- Not for 411i Max
- Generic replacement
Smilyan is the better choice for original Blue Pure 411, 411+ and 411 Auto owners who want 3 filters in one pack. It combines particle filtration, activated carbon and a fine pre-filter.
The fine pre-filter is a meaningful detail for daily use. It can catch larger particles before they reach the main particle layer, which may help the core filter deal with finer material.
The filter uses paper material and has a pleated construction. That format fits the original 411 family and gives the pack a different value from a single genuine replacement.
Smilyan identifies it for the original 411 family and specifically excludes the 411i Max. That warning should be read as a hard stop for owners of the newer Max model.
That distinction is central to the buying decision. The larger pack may reduce how often you reorder, but it cannot replace a filter designed for a different 411 generation.
Choose Smilyan when your purifier is an original 411, 411+ or 411 Auto and you prefer a three-filter supply. Choose the genuine BLUEAIR option when brand-matched replacement matters more than pack size.
iSingo 511i MAX Replacement Filter for BLUEAIR: Best for 511i Max two-filter supply
- Fits Blue Pure 511i Max
- 2 filters included
- HEPA and activated carbon filter materials
- Pleated construction
iSingo is made for the Blue Pure 511i Max and includes two filters. The filter materials combine HEPA filtration with activated filtration, while the compatibility notes exclude the older 511 model.
Pros
- Two-filter pack
- Dedicated 511i Max fit
- Activated filtration included
Cons
- Not for Blue Pure 511
- Generic replacement
iSingo is the dedicated replacement for the Blue Pure 511i Max. It includes 2 filters and combines HEPA filter material with activated filter material.
The HEPA side is aimed at fine airborne particles such as smoke, dust and pet dander. The activated layer adds support for light household odors, so the pack suits a room where both particle and odor control matter.
The stated dimensions are 10 x 6.25 x 2.7 in. Those measurements help confirm fit for the 511i Max housing before you remove the old filter.
iSingo identifies the filter for the BLUEAIR HEPASilent air cleaner, Blue Pure F5MAX and Blue Pure 511i Max. The model list is short, which makes the check simple if your label matches exactly.
It does not fit the Blue Pure 511, 211+, 411i Max, 411a max, 311 or 121. The older 511 in particular is a common trap because the names look alike.
If you own the 511i Max, our guide to the best Blueair 511i Max filter replacement covers the same model group in more detail.
Choose iSingo for the 511i Max when you want two replacements. The model name must include the “i Max” designation because the older 511 is excluded.
Ganteny Classic 200/300 Series Particle HEPA Filter: Best for Classic 200 and 300 series
- Fits Classic 201, 203, 205, 215B, 250E, 270E and 303
- 2 filters included
- Particle HEPA filtration
- Fiberglass material
Ganteny covers a wide group of older Blueair Classic 200 and 300 series models. The two-pack uses pleated fiberglass particle HEPA filters and does not describe an activated carbon layer.
Pros
- Fits 7 Classic models
- Two-filter pack
- Particle HEPA design
Cons
- Generic replacement
- Particle filter focus
Ganteny’s Classic 200/300 replacement covers 7 older Blueair models: 201, 203, 205, 215B, 250E, 270E and 303. It includes 2 pleated fiberglass particle HEPA filters.
The particle focus suits older Classic purifiers kept in a bedroom or living room. It is aimed at dust, pollen and pet dander, which are the main concerns in many homes with pets or seasonal pollen.
The stated dimensions are 17.9 x 1.8 x 14.3 in. Classic housings vary by series, so comparing those dimensions with the old filter is a sensible extra check.
The filter is designed around particle filtration, and the product information does not identify an activated carbon layer. Owners who mainly want odor reduction may want to weigh that trade off before choosing.
Choose this option when your Classic purifier appears in the compatibility list and particle filtration is your main need. Check the model number carefully because Classic series names span several filter shapes and sizes.
The two-pack is useful for keeping a replacement on hand. It is a generic filter, so buyers who prefer a genuine BLUEAIR replacement should look at the compatible original-series options instead.
Ganteny 3-Pack Classic 500/600 Series HEPA Filter: Best for Classic 500 and 600 series supply
- Fits Classic 501, 503, 505, 510, 550E, 555EB, 601, 603, 605 and 650E
- 3 filters included
- HEPA and carbon layer
- 13 x 9.3 x 2.6 in
This Ganteny three-pack suits owners of many Classic 500 and 600 series purifiers. It combines a HEPA filter with a carbon layer and gives you three replacement elements.
Pros
- Three-filter pack
- Fits 10 Classic models
- Carbon layer included
Cons
- Generic replacement
- Exact model check still required
Ganteny’s 500/600 series filter is made for a broad range of Classic models, including 501, 503, 505, 510, 550E, 555EB, 601, 603, 605 and 650E. It includes 3 filters with HEPA material and a carbon layer.
The three pack is the main practical draw for larger Classic units. Having spare filters on hand can make replacement day quicker, especially if the purifier runs often in a busy living space.
Each filter measures 13 x 9.3 x 2.6 in. That rectangular size is distinct from the Classic 200/300 format, so the series check matters even within the same Classic family.
The carbon layer gives this option a different role from the Classic 200/300 particle filter, especially when household odors are part of your replacement decision. HEPA filtration handles particles such as smoke, dust and pollen, while carbon is added for odors and VOCs.
Ganteny identifies the filter as a generic replacement rather than a Blueair OEM product. That makes exact model matching important before you order.
Choose this pack for a compatible Classic 500 or 600 series purifier when three replacements are useful. It is not intended for the newer Blue Pure i Max models.
MGCADI （2 Pack）211+ Auto Replacement Filter Compatible: Best for 211+ Auto two-filter value
- Fits Blue Pure 211+ and 211 Auto
- 2 filters included
- H13 true filter and activated carbon
- Non-woven fabric and carbon material
MGCADI gives Blue Pure 211+ and 211 Auto owners two filters with an H13 true filter and activated carbon. Its model range overlaps the genuine 211+ option but adds support for the Auto model.
Pros
- Fits 211+ and 211 Auto
- Two-filter pack
- H13 and carbon filtration
Cons
- Generic replacement
- Exact purifier model matters
MGCADI is the best fit here for owners of the Blue Pure 211+ or 211 Auto who want two filters. Its 2-in-1 design combines an H13 true filter with activated carbon.
The H13 true filter is aimed at fine particles down to 0.3 microns. That suits homes with pets, dust and pollen where particle capture is the priority.
The activated carbon side helps with unpleasant household odors and fumes. Cooking odors, smoke and pet odors are the kinds of smells carbon filtration is meant to address.
The filter uses non-woven fabric and activated carbon material. It has a round shape and stated dimensions of 11.7 x 11.7 x 11.7 in, which is a clear visual difference from rectangular filters.
The key advantage is model coverage: MGCADI names both the 211+ and 211 Auto. That makes it a useful alternative to the genuine BLUEAIR 211+ option when your machine is the Auto version.
Choose it when you need a two-pack for one of those two models. If you own the standard 211+ and want a genuine BLUEAIR filter, the BLUEAIR 211+ replacement above is the more direct match.
How should you match a Blueair replacement filter to your purifier?
Match the full model name before comparing filter materials or pack sizes. The most common mix-ups in this group are original 411 versus 411i Max, 211+ versus 211 Auto, and 311i Max versus 311i+ Max.
Those names differ by small letters and symbols. A quick glance can easily miss the difference, so slow down and read the whole label rather than relying on the first number.
Look for the model label on the purifier or in its manual. Then compare that name with the compatibility line for the filter you plan to use.
Keep the old filter nearby when you compare. Its size and shape can confirm that the new one matches the housing you already have.
A filter can have the right brand name and still be wrong for the machine. The WILERDA filter, for example, is for the 311i Max but specifically excludes the 311i+ Max.
The same rule applies to compact models. Original 411 replacements from BLUEAIR and Smilyan do not cover the 411i Max.
Classic models need the same care. A 200/300 series filter and a 500/600 series filter may both fit older Blueair purifiers, but they are not interchangeable.
Dimensions are a useful second check after the model name. If the size looks very different from the filter you removed, pause before forcing a fit.
Pack size should come after compatibility, not before. A two pack or three pack is only good value if every filter in it fits your purifier.
Carbon is a third check, not the first. Once fit is confirmed, decide whether you need activated carbon for odors or whether particle filtration alone meets your goal.
Write the model name down before you shop. That simple note makes it easier to compare listings without mixing up Max, Auto and older series names.
Do carbon filters matter for Blueair air purifier replacements?
Activated carbon matters when odor control is part of your goal. Carbon is used alongside particle filtration in several picks here, including the genuine BLUEAIR 411 and 211+ filters, WILERDA, isinlive, Smilyan, iSingo, Ganteny 500/600 and MGCADI.
Particle filters and carbon filters do different jobs. Particles such as dust and pet dander are captured by the filter media, while carbon is aimed at odors and some gases.
That difference shows up in daily use. In a kitchen, carbon may help with cooking smells, while in a bedroom with pets it can support control of pet odors alongside particle capture.
Read our guide to What Is a Charcoal Filter in an Air Purifier? for a simple explanation of how charcoal-based filtration differs from particle filtration.
A carbon layer does not mean the particle side can be ignored. A filter still needs the right size and construction for your purifier model.
It also does not mean every odor will be handled the same way. Strong or ongoing sources may overwhelm any carbon layer faster than light household smells.
Carbon does not replace the need for a correctly sized particle filter. Choose a filter that matches your purifier first, then compare whether it includes carbon.
If odor control is not a concern, a particle focused option may be enough. If cooking, smoke or pet smells bother you, a carbon equipped filter is usually the more complete match.
Check the pack details too. Some carbon filters are built into a single combined element, so there may be no separate carbon sheet to change on its own.
What does a pre-filter do in a Blueair replacement?
A pre-filter catches larger particles before air reaches the main filter. Smilyan identifies a fine pre-filter in its 411 replacement, while other products in this guide emphasize particle, HEPA or activated carbon layers.
That early layer can act as a first line of defense. Larger dust and lint may be caught sooner, which helps keep the main filter focused on finer particles.
The benefit is practical rather than dramatic. A pre-filter may support longer main filter life in a dusty room, but it does not remove the need to replace the whole element on schedule.
Our guide to What Is a Pre Filter in an Air Purifier? explains where that layer fits in a multi-stage air-cleaning system.
Not every filter in this guide lists a pre-filter. If that layer matters to you, check the product details for Smilyan rather than assuming other packs include it.
Keep the purifier's exterior and intake areas clear during normal use. Blocked intake can reduce airflow and make any filter work harder than it needs to.
Replace the filter when the purifier indicates service or when the stated replacement period and your indoor conditions point to a change.
Homes with pets, carpet or frequent dust may need closer attention. A quick look at the filter at replacement time can show whether the stated interval fits your room.
Store spare filters in a dry place until they are needed. That keeps the pre-filter and main media clean and ready for the next swap.
How do you install and care for a replacement filter?
Most options here are slide-in replacements that do not require tools. Turn the purifier off, remove the used filter, compare the new filter's model fit, and install it in the same orientation as the old one.
Follow the purifier manual for any filter indicator reset. Do not force a filter that does not slide into place, because resistance can signal a model or orientation mismatch.
Replacement timing varies by product. Several options state about 6 months, while others describe 6–8 months or up to 9 months depending on use and indoor air quality.
Store an unused filter in a dry location, especially when the product instructions call for moisture protection. Keep the package information available so you can confirm the model before the next replacement.
Which Blueair air purifier filter replacement should you choose?
Choose the genuine BLUEAIR 411 Series filter for the original 411, 411 Auto or 411+ when direct brand matching matters most. Pick WILERDA for the Blue Pure 311i Max, the genuine BLUEAIR filter for the standard 211+, and MGCADI for the 211+ Auto.
For Mini Max models, choose isinlive. For 511i Max, choose iSingo.
Classic 200/300 and 500/600 owners should use the Ganteny filter that names their exact series and model numbers.
If you own an original 411 and want a larger supply, Smilyan is the pack option to compare. Its three filter format may suit owners who prefer to keep spares on hand.
If odor control is a priority, look for activated carbon in the filter you shortlist. Several options here combine carbon with particle filtration, while the Classic 200/300 Ganteny filter is particle focused.
Replacement timing depends on the product and your room. Many listings in this guide point to about 6 months, while others describe longer ranges, so follow the interval stated for the filter you buy.
The best Blueair air purifier filter replacement is the one that matches your full model name, includes the filtration layers you need and gives you a pack size that fits your replacement routine.
Take the model check first, then compare carbon, pack size and dimensions. That order keeps the decision straightforward and helps you avoid a filter that looks right but fits the wrong purifier.

Frequently asked questions
How do I choose a Blueair air purifier filter replacement?
Start with the exact purifier model, not just the Blueair brand. A 311i Max filter is not the same as a 311i+ Max filter, and a 411 replacement does not fit the 411i Max.
Then compare particle filtration, activated carbon, pack size and the stated dimensions.
Are Blueair 411 and 411i Max filters the same?
No. The BLUEAIR Genuine 411 Series replacement fits Blue Pure 411, 411 Auto and 411+, while Smilyan also covers those original 411 models.
Smilyan specifically excludes the 411i Max, so check the model label before ordering a Blueair air purifier replacement filter.
What is the difference between a 211+ and 211+ Auto filter?
The genuine BLUEAIR 211+ replacement is identified for the Blue Pure 211+ model. The MGCADI two-pack is identified for both Blue Pure 211+ and 211 Auto.
If your purifier is the Auto version, choose a filter whose compatibility names that model.
How often should Blueair replacement filters be changed?
The products in this guide commonly state replacement periods of about 6 months, while some describe 6–8 months or up to 9 months. Actual timing depends on use and indoor conditions.
Check the purifier's filter indicator and inspect the filter when airflow or odor control changes.
Do Blueair replacement filters remove odors?
Filters with activated carbon are the better match for common household odors because carbon is included alongside particle filtration. The genuine 411 and 211+ filters, WILERDA, isinlive, Smilyan, iSingo, Ganteny 500/600 and MGCADI options all identify carbon or activated carbon in their materials.
