Top 10 Best Air Purifiers for Dust Removal and Dust Mites in 2022

By 2022, we will have advanced in ways that we could never have imagined in the preceding decade. Every day, we can address hundreds of issues that 100 years ago we could only sit and be miserable about. However, we continue to face a sufficient number of daily issues. And one among them is dust, which is comprised of microscopic particles such as textile fibers, paper, hair, pet dander, skin cells, dust mites, and filth. This is as insane as you need to instantly switch on your laptop and search for the best air purifiers for dust removal.

DISCLAIMER: We’ve evaluated and measured 400+ air purifiers over the last few years to compile the most comprehensive air purifier ranking list available.

UPDATED: We have updated our list of best air purifiers for dust removal on 04/11/2022. In Breathe Quality, we keep updating our posts whenever possible, and this update is the result of a new updated system to rank air purifiers. Our next update will be set for 3-6 months later, depending on the release of new products from the well-known air purifier brands. However, you don’t need to wait, because the air purifier market will never change so quickly.

Let’s face the fact, why you need such a solution for your dust problems? Mostly because of:

  • You (or your family member) have recently suffered or developed symptoms of allergies. Definitely the culprit is your home dust and/or dust mites.
  • Do you enjoy your life in a home covered with dust? Almost, dust and dust mites can be found anywhere in your home, the couch, bed or shelves.
  • You are fed up of cleaning your home out of the dust everyday, right? I bet someone really hate this chore.

Because you are here, let’s not waste countless hours of searching through any others of websites just to find the top rated air purifiers that fit your specific needs. Because in Breathe Quality:

  • We do give honest reviews (both pros and cons) and a base comparison for all the air purifiers so anyone will guarantee to have the wisest choices.
  • We do not (and we never) exaggerate one product just to let you click the links and buy that product blindly.
  • Air purifiers are for everyone. Believing that, we will give you the best air purifiers from low-range to high-range. To know the exact price of your air purifier, make sure to hit the Check price button.

Dust and dust mites are in fact microscopic. Also, dust includes a diversity of debris, contaminants, and allergens (viruses). To stop these annoying problems, the best air purifier for dust needs to have:

  • True HEPA Filter – The most used air filter with powerful filtration process to capture up to 99.97% of as small as 0.3 microns particles. To stay in this list of best air purifiers for dust, an air purifier must have True HEPA filter or better.
  • Good CADR (Dust-free) rating for Room coverage – CADR rating tells exactly how fast your air purifier could clean an amount of dust in one specific time. CADR rating is mostly for indicating the fan power of your air purifier.
  • Ionizer – Having an ionic filter is a plus, it will help capturing the dust and dust mites easier. However, the air purifier with ionizer feature must comply with the standards set forth by the California Air Resources Board (CARB) for ozone emission concentration limit. So far, if you find an air purifier in a Breathe Quality’s list of best air purifier for dust removal, it must be certified by the CARB.
  • Smart Sensor is another plus, to help you operate the air purifier automatically.

Keep all these rules above in your mind whenever looking for an air purifier for dust removal in 2022. Not like any other reviewers, we show you the reasons why you should believe in the Breathe Quality’s list. As a matter of fact, we hope nothing but your health.

2) Blueair Classic 680i – The High-end Machine with Alexa

 Previously in our list:   Blueair Classic 605.

It’s hard to know where to start with the Blueair Classic 680i, because Blueair has really gone to town here, from the unmatched fan power to the exclusive Blueair HEPASilent filter technology. It’s the priciest of the Classic family from this brand, and it shows.

If you are finding the best air purifier for dust removal in 2022, you can’t skip this powerful high-end Blueair Classic 680i. A well-built machine made by Blueair, this air purifier is the best line of defense you can have against dust and dust mites.

  • High CADR for Dust – 400 cfm.
  • Smart Sensor – yes.
best air purifier for dust

With just only one type of filter, it is really simple to purchase and/or install the filter replacement. The top-notch HEPASilent technology of Blueair Classic 680i can have an awesome removal of 99.97% of dust particles down to 0.1 microns. You hate dust and dust mites? They hardly can escape the air filtration system of a Blueair air purifier.

Not to mention the Blueair Classic 680i’s robust fan power, which ensures the air purifier can operate effectively in even the largest rooms. No ordinary word could adequately convey how strong a fan with a high CADR rating of 400 cfm for Dust, such as the Blueair Classic 680i, can be. Additionally, with a high ACH rating of 5X, we’re confident that even if you want to use this air purifier in a space up to 1000 square feet, it will perform better than any other device.

The Blueair Classic 680i is highlighted as a high-end machine due to its ability to be managed via a smartphone app and/or Alexa voice commands. That is why Today’s Parent magazine recommends the Blueair Classic 680i as an excellent alternative for any family.

The Blueair Classic 680i has an inbuilt Smart Sensor as it is simply the upgraded version of the former Blueair Classic 605 that won a title as the best air purifier for dust last year.

3) Austin Air HealthMate Plus – Simple but top-notch performance

 Previously in our list:   Austin Air HealthMate Plus.

The Austin Air HealthMate Plus is the signature air purifier made by Austin Air, which is one of the largest air purifier manufacturing facilities in the world. This air purifier is a powerhouse with no features, just pure performance to purify the air.

  • Air filtration process – Austin Air HealthMate Plus has double pre-filters and one of the best True HEPA filters in real-world to deal with dust and dust mites.
  • High CADR for Dust – 400 cfm.
  • Smart Sensor – no.
best air purifier for dust removal

High-range segment was the playground for only the powerhouse air purifiers without any smart features, just like the Austin Air HealthMate Plus, until something like the Blueair HealthProtect 7770i comes and changes that. However, if we’re asked which air purifier has the best HEPA filter in the world, no doubt it would be this Austin Air machine. And, as no one can dispute, the Austin Air HealthMate Plus can perform admirably with only its True HEPA filter, rather than combining it with other types of ionizer or electrostatic filter media. Simple, yet flawless.

And just don’t mess with the fan power of Austin Air HealthMate Plus, it can effectively cover a room of 700 square feet with an impressive high CADR rating for Dust-free of 400 cfm. Also, this fan can run as high as 5X ACH to serve you well.

Due to the high fan power and high-quality filters, the Austin Air HealthMate Plus will sacrifice some of the smart features, most notably the convenient Smart Sensor that we’ve always desired in an air purifier. In fact, this air purifier offers no feature.

In our air purifier ranking list, Austin Air HealthMate Plus ranks only C+, but its performance alone ranks A+, which is only behind the Blueair HealthProtect 7770i for high CADR rating > 400 cfm.

Here is the pros/cons of Austin Air HealthMate Plus:

PROS


  • High performance rating True HEPA Filter
  • High Fan Power with High CADR for Dust: 400 cfm
  • High-quality materials
  • 5-year warranty
CONS


  • Lacks of Smart Features
  • Quite noisy

4) AIRMEGA 400 – The best air purifier for out-and-out value

 Previously in our list:   AIRMEGA 400.

Glitzier, flashier and far more cheaper than the previous Austin Air HealthMate Plus, the AIRMEGA 400 sits at the top of Coway’s current AIRMEGA lineup, along with its Wi-Fi Enabled AIRMEGA 400S sibling. As the flagship of the No.1 air purifier company in South Korea could offer, the AIRMEGA 400 is one of the best air purifiers for dust removal you could get at the moment.

  • Air filtration process – AIRMEGA 400 will have a powerful washable pre-filter and a thick True HEPA filter to deal with your dust and dust mite problems.
  • High CADR for Dust – 340 cfm.
  • Smart Sensor – yes.
best air purifier for dust removal

The AIRMEGA 400 device builds on the experience of the air purifier company that’s even stronger than Samsung in the domestic market, to add even more in the way of functionality and features. It has a pre-filter to help trap the large dust and dust mites, and most importantly, the pre-filter is washable so it lasts permanently.

The True HEPA filter of AIRMEGA 400 not only removes 99.97% of all airborne particles ≥ 0.3 microns, which covers most types of dust and dust mites, it also reduces 99% of Volatile Organic Compounds (VOCs), thanks to the combination with Activated Carbon filter. All the internal specs are remarkably premium considering its super low annual filter replacement cost, compared with the Medify MA-112 and Blueair Classic 605.

You don’t need to be concerned about the AIRMEGA 400’s performance, owing to its high CADR rating of 340 cfm for Dust-free, as certified by the Association of Home Appliance Manufacturers (AHAM). Cleaning a room up to 1560 square feet based on a 2X ACH rating is advised, and 780 square feet based on a 4X ACH rating.

We chose the AIRMEGA 400 above the previous holder of the best air purifier for dust removal because it features a convenient Smart Sensor that monitors the current air quality and adjusts the fan speed accordingly.

In our air purifier ranking list, we only rank the AIRMEGA 400S at A+, meaning it’s only behind the best Blueair HealthProtect 7770i.

Here is the pros/cons of AIRMEGA 400:

PROS


  • Undeniable performance rating
  • Highest quality materials and sleek design
  • Amazing Fan Power with High CADR for Dust: 340 cfm
  • A lot of Smart features
CONS


  • Has only 3-year warranty

5) Sharp FX-J80UW – Unique technology from Japanese brand

 Previously in our list:   Sharp FP-A80UW.

Sharp, being a leader in Japan’s electronics sector, is extremely well-known throughout Asia and Africa. While we haven’t heard much from this brand about air purifiers, their products are among the finest in the mid-range sector. Let’s see whether Sharp’s most recent flagship – the Sharp FX-J80UW can sway your judgment.

  • Air filtration process – A great True HEPA filter combines with the unique Plasmacluster technology.
  • High CADR for Dust – 334 cfm.
  • Smart Sensor – yes.
best air purifier for dust

Sharp FX-J80UW is a huge deal when it comes to dust and dust mites, especially when combined with its patented Plasmacluster technology. Unlike conventional ionizers, this technology will not aggravate asthma owing to the unique way ions are used. Additionally, we will be pleased with the True HEPA filter life of the Sharp FX-J80UW, which may last up to two years without filter change.

While remaining in the mid-range market, the Sharp FX-J80UW earns an exceptional CADR rating of 334 cfm for dust-free operation. If you want to use this air purifier, bear in mind that it is most effective in rooms up to 500 square feet, certified by the Association of Home Appliance Manufacturers (AHAM).

Sharp FX-J80UW, like other high-end air purifiers, includes a Smart Sensor, a Timer, and an LED filter change indication. Additionally, the Library Quiet technology works really well, ensuring that this air purifier operates as quietly as possible. Sharp FX-J80UW is the finest air purifier for dust in the mid-range price range.

In our air purifier ranking list, Sharp FX-J80UW ranks A+, second to only Blueair HealthProtect 7770i.

Here is the pros/cons of Sharp FX-J80UW:

PROS


  • Best performance rating with Innovative and great air filtration process
  • High Fan Power with High CADR for Dust: 334 cfm

6) Blue Pure 121 – A pure air purifier for dust removal purpose

 Previously in our list:   Blue Pure 121.

Certain air purifiers are created with simplicity and ease of use in mind, and the Blue Pure 121 is one of them. This air purifier is the perfect alternative to any high-range air purifiers that are $300 more expensive, such as the former holder of the top spot in our list of the best air purifiers for dust removal and dust mites.

  • Air filtration process – Blue Pure 121 has a fabric pre-filter to catch any kinds of particles before entering an exclusive Particle filter to guarantee the capture of every dust and dust mite.
  • High CADR for Dust – 400 cfm.
  • Smart Sensor – no.
best air purifier for dust removal

Blue Pure 121 is comfortably one of the best air purifiers available for a mid-range budget; it excels on all fronts. To begin, the greatest air purifier in the Blue family utilizes Blueair’s advanced HEPASilent technology, which removes 99.97 percent of all pollutants down to 0.1 microns. Due to the wider surface area and less thick filter material, the air filter has a higher capacity and a longer filter life.

Speaking of the powerful fan, we can not ignore the high CADR rating of 400 cfm for Dust-free. It can match any Austin Air or Airpura air purifiers with around $200 – $300 more expensive price tag than the Blue Pure 121.

Though powerful, the Blue Pure 121 is a traditional air purifier with only one control button. If you’re searching for smart features such as Smart Sensor, you’re going to be disappointed.

In our air purifier ranking list, Blue Pure 121 ranks C+, with an S- in performance ranking.

Here is the pros/cons of Blue Pure 121:

PROS


  • Top-class performance
  • High-quality air filter, 100% recyclable
  • Fantastic Fan Power with High CADR for Dust: 400 cfm
  • 360° air intake

7) Levoit Core 600S – A solid, affordable air purifier with high performance

The Levoit Core 600S is easily a solid, affordable alternative to the previous Blue Pure 121 air purifier. With its absolutely stunning performance, the Levoit LV-H134 in undeniably one of the best air purifiers for dust removal at the moment

  • Air filtration process – Levoit Core 600S also has one pre-filter and one True HEPA filter to remove dust and dust mites.
  • High CADR for Dust – 373 cfm.
  • Smart Sensor – yes.
best air purifier for dust

It’s a testament to how good Levoit air purifiers have gotten that the Levoit Core 600S benefits from enhancements to the H13 True HEPA filter that make it comparable to any mid-range devices. It is 99.97 percent effective at capturing dust particles as small as 0.3 microns, as well as other types of pollutants.

Levoit Core 600S makes use of a very prominent fan power, which is developed since the old Levoit LV-H134 – the previous holder in our list of the best air purifiers for dust removal and dust mites. With a high CADR rating of 373 cfm for Dust, this air purifier can easily cover a room of 700 square feet.

The Levoit Core 600S is distinguished by its high-end laser sensor, which provides a more accurate reading of the present indoor air quality index in less than 30 seconds. Additionally, the air purifier can be controlled via its VeSync app, as well as you can use Alexa voice commands.

In our air purifier ranking list, Levoit Core 600S ranks A+, again this air purifier is only behind the best Blueair HealthProtect 7770i.

PROS

8) Rabbit Air MinusA2 – Many mechanical filters for better result

 Previously in our list:   Rabbit Air MinusA2.

One again, we will have Rabbit Air MinusA2 to stand in Breathe Quality’s list – one of the best air purifiers for dust removal. If both performance and value are considered, we will automatically place this air purifier at the top of every ranking. However, Rabbit Air MinusA2’s low fan power is a significant disadvantage. Nonetheless, you will be pleased with the unmatched performance.

  • Air filtration process – Rabbit Air MinusA2 portraits an unique 6-layer air filtration process with True HEPA filter and Ionizer.
  • High CADR for Dust – Only 193 cfm.
  • Smart Sensor – yes.
best air purifier for dust removal

We are looking at the masterpiece of air purifier, Rabbit Air MinusA2. This air purifier does not have the standard three or four filters. Indeed, Rabbit Air MinusA2 features no less than six levels of filtration. The bottom line is the outstanding performance rating, which includes double pre-filtration, a user-adjustable filter, a single strong True HEPA filter, and even an optional ionizer. There is no way you can disregard Rabbit Air MinusA2 when it comes to dust and dust mite eradication.

Also, Rabbit Air constructs its True HEPA filter using only the greatest quality materials and innovative technologies. That is why you may operate Rabbit Air MinusA2 for up to 2-3 years without replacing the filter.

However, this air purifier is not perfect. To trade off with a high technology and silent fan design, Rabbit Air needs to sacrifice the fan power. That’s why the low CADR of 193 cfm for Dust is nowhere near the room coverage of 815 square feet.

In conclusion, Rabbit Air MinusA2 is still a great high-end air purifier. You will benefit a lot from this air purifier’s Smart Sensor and Wi-Fi capability.

In our air purifier ranking list, Rabbit Air MinusA2 ranks A.

Here is the pros/cons of Rabbit Air MinusA2:

PROS


  • Remarkable performance rating with top-class air filtration process
  • Well-built with highest quality materials
  • Impressive design and art
  • Ultra quiet
  • Smart features like Smart Sensor and Wi-Fi capability
  • 5-year warranty
CONS


  • Low Fan Power with Low CADR for Dust: 193 cfm

9) Coway AP-1512HHS – Best bang for the buck

 Previously in our list:   Coway AP-1512HH.

As the direct upgrade for the proud child of the Korean #1 brand for air purifier in last year – Coway, let’s see whether Coway AP-1512HHS is a good option for the best air purifier for dust removal and dust mites.

  • Air filtration process – Coway AP-1512HHS makes use of a mechanical air filtration process with a pre-filter and a True HEPA filter.
  • High CADR for Dust – 246 cfm.
  • Smart Sensor – yes.
best air purifier for dust

Coway AP-1512HHS is one of the few air purifiers that could match the performance rating of the powerful Honeywell HPA300. With only a 3-stage air filtration process including a True HEPA filter, it is simple for the Coway AP-1512HHS to reduce 99.97% down to 0.3 microns particles like dust and dust mites.

For the fan power, with the same price tag, Coway AP-1512HHS loses a little compared with Honeywell HPA300. Its CADR of Dust is only 246 cfm and the room coverage is 360 square feet.

On the bright side, the Coway AP-1512HHS includes a slew of intelligent features, including Smart Sensor and, most notably, Eco Mode. Combining these two modes results in one of the most energy-efficient air purifiers in the world (if not want to say the best).

In our air purifier ranking list, Coway AP-1512HHS ranks A+.

Here is the pros/cons of Coway AP-1512HHS:

PROS


  • Amazing performance rating with True HEPA filter and Ionizer
  • Good Fan Power with Medium CADR for Dust: 246 cfm

  • Air filtration process – GermGuardian AC9400W has a pre-filter and a True HEPA filter to combat with dust and dust mites. It also has an optional ionizer to increase the efficiency.
  • High CADR for Dust – 263 cfm.
  • Smart Sensor – yes.
best air purifier for dust removal

GermGuardian AC9400W is currently the best air purifier from the US company. Its amazing performance is made by the ultimate combination of True HEPA filter and ionizer, as well as a high fan power. As a result, this air purifier can capture any dust or dust mite particles as small as 0.3 microns. Moreover, GermGuardian AC9400W’s power is certified by both the AHAM and Energy Star, for the best performance per power ratio.

This is also the rare air purifier in Guardian Technologies’ line up with Smart Sensor, a feature that adjusts fan speed accordingly to the environment. This feature can help you save energy much better.

However, the problem of this air purifier is its high filter cost, so it’s quite expensive to maintain it annually. In our air purifier ranking list, GermGuardian AC9400W only ranks B+, but its performance alone rank S-.

Here is the pros/cons of GermGuardian AC9400W:

PROS


  • Great performance rating
  • Good CADR for Dust: 263 cfm
  • Has Smart features like Smart Sensor
  • AHAM & Energy Star ratings

What is Dust? What are Dust Mites?

Dust is not strange to anyone. In real-world situations, dust is one of the most annoying things to deal with. Although it will often look like uniform grey dirt or dead skin cells when it settles on surfaces, dust actually contains a wide range of particles and elements shed from a surprising number of sources.

  • Soil that is tracked into the home
  • Particulate matter from outside air
  • Organic material

Dust mites are microscopic creatures. They are related to the spider. They flourish in warm, humid weather and are commonly found across the world. Dust mites feed on human and animal dead skin cells.

To know why you need an air purifier to get rid of dust and dust mites, you can check our below articles:

2, Do air purifiers get rid of dust mites?

Terminology and Definition for best air purifiers for dust removal and dust mites in 2022

For the complete buying guide, you can read here.

Pre-filter – An essential feature of air purifiers that use a HEPA style filter. The pre-filter captures large dust and pet dander to help prolong the lifetime of the main filter. Most pre-filters are washable and reusable and last a lifetime.

True HEPA Filter – This is the highest standard air filter you can get for a best air purifier. In order to carry this label, the filter must meet strict regulations set by the United States Department of Energy (DOE) and capture at least 99.97% of particles as small as 0.3 microns. A true HEPA filter needs to be replaced after 6 months to 1 year, and you should use a suitable replacement for your air purifiers.

Ionic Filter (or Ionizer) – This filter emits negative ions to charge small particles like dust, pollen and bacteria and collect them into a plate.

Plasmacluster technology – A technology from Sharp, which is unlike the normal ionizer. These ions not only just attract contaminants to make a bigger form, but these ions can also extract the protein components of mold spores and viruses.
