Top 10 Best Large Room Air Purifiers in 2022 (over 300, 500 square feet)

There are always large rooms in this world, right? Perhaps they are one or two huge rooms in your house, a hotel suite with a 5-star rating, or even a conference space. A big room has a vast volume of air that can be somewhat polluted. Here are the reasons you are looking for the best large room air purifiers for your needs.

DISCLAIMER: We’ve evaluated and measured 400+ air purifiers over the last few years to compile the most comprehensive air purifier ranking list available. We spent hours narrowing down the competitors to a top 10, taking into account each device’s performance, power, features, a bit of design, and, most importantly, its value for money.

  • You discovered that your air purifier is insufficient for your huge space (more than 300 or 500 square feet) or is completely ineffective.
  • You had a huge space with a large number of people (conference halls, restaurants, or hospitals) and require a large room air purifier to suit everyone’s demand.

Let’s not waste your precious time searching for many other website reviews and ratings. You will be overwhelming for sure! Meanwhile 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 (in fact, 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 in all price ranges. To know the exact price of your air purifier, make sure to hit the Check price button.

Important Note: If you have a small room, we highly recommend that you read our list of the best small and quiet air purifiers in 2022.

A big room exceeding 300, or even 500 square feet, is a massive airflow space. An air purifier requires a lot of fan power to inhale and exhaust such a vast volume of air. As a result, you cannot expect a low-cost air purifier to perform such a demanding work. We will bring you the top 10 most powerful large room air purifiers in 2022.

Our today list of the best large room air purifiers will be very simple, the top 1 will be the best performer while the top 10 is the least. We only accept air purifiers with high fan power (CADR rating ≥ 350) and high performance (ranking ≥ A- in performance). Are we clear?

UPDATED: We have updated our list of best large room air purifiers on 04/11/2022, as a result of the new updated ranking list.

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.

Best Large Room Air Purifiers – The Most Powerful List in 2022

1) Blueair HealthProtect 7770i – Our 2022 Champion, Rank S-

 Previously in our list:   Blueair Classic 605.

Blueair has also been a well-known name in the air purifier industry for over two decades. After years of expertise, it’s safe to say Blueair is a reliable source for air purifiers, particularly when it comes to huge air purifier machines for large rooms.

The Blueair HealthProtect 7770i is simply the best large room air purifier, according to our new air purifier ranking list, ranking S- with S in performance. This air purifier can cover an extra large room of 700 square feet, verified by the Association of Home Appliance Manufacturers (AHAM).

However, do not be fooled by the reduced room coverage; the Blueair HealthProtect 7770i is one of the most powerful air purifiers on the market today, with an unmatched fan power. This air purifier has a CADR rating of 400 Dust/ 435 Smoke/ 435 Pollen (cfm) and an ACH rating of 5X.

best large room air purifier

In terms of power, Blueair HealthProtect 7770i is the most powerful and economical air purifier we’ve tested. Its high fan power nearly reaches the Blueair Pro XL for only a third of the price. Blueair HealthProtect 7770i’s internal air filtration system is the latest HEPASilent Ultra technology made by Blueair, with 2 stages as below:

  1. Pre-filter – For best performance, you’re required to clean the pre-filter regularly. It can trap large objects of pollutants, to prolong the life time of the Smart Filter.
  2. Smart Filter – The most advanced filter technology of Blueair, it can remove airborne pollutants and allergens such as pollen, dust, pet dander, mold spores, fine smoke particles and more. It is covered by activated coconut shell carbon, to adsorb chemicals, Volatile Organic Compounds (VOC), and annoying household odors from cooking, smoke, and pets.

Since we released our new updated ranking list for 400+ air purifiers, the Blueair HealthProtect 7770i has won the title of the best air purifier for many list, including the best large room air purifier. It has a top-notch performance rating and a superior style, as well as high-end features that you can’t get in the Pro Series – the Smart control through Wi-Fi and Alexa, which is especially necessary in a large room. Finally, the Smart Sensor is extraordinary, as you can simply set it and forget it.

Here is the pros/cons of Blueair HealthProtect 7770i:

PROS


  • Large Room coverage: 700 square feet
  • Most powerful fan power in the world
  • World class performance rating and amazing air filtration
  • Well-built with highest quality materials

2) Levoit Core 600S – The Best Bang for the Buck, Rank A+

 Previously in our list:   Levoit LV-H134.

The air purifier from Levoit proves that this brand can really make the air purifiers targeting large rooms (over than 500 sq ft). The Levoit Core 600S even go far, ranking A+ as well as position 2 in our list of the best large room air purifier.

The Levoit Core 600S is also the best bang for the buck, with its price goes lowest in the clash of the large room air purifiers, winning over its former LV-H134 with room coverage of 700 square feet.

This air purifier upgrades to a CADR of 373 Dust/ 377 Smoke/ 437 Pollen (cfm), which is the highest among any air purifiers under $300. In our air purifier ranking list, Levoit Core 600S ranks A+ with S in performance.

best large room air purifier

Levoit Core 600S raises as a large room air purifier with a signature air filtration system from the very first Levoit air purifier. We still have a 3-stage air filtration system as below:

  1. Pre-filter – This mesh pre-filter can capture airborne large objects like dust, pet dander, pet hair, lint and fiber. This pre-filter is mostly for maximizing the True HEPA filter life.
  2. True HEPA filter – A H13 True HEPA Filter can reduce 99.97% down to 0.3 microns all contaminant particles like dust mites, allergens, pollen, and mold spores.
  3. Activated Carbon Filter – The custom high-efficiency Activated Carbon filter (ARC formula) is especially effective for cooking smells and pet odors in a multi-pet household. It also extends the life of the filter by chemically decomposing molecules trapped within the Activated Carbon Filter, which prevents oversaturation and second-hand pollution.

Levoit Core 600S revamps the air filtration system from the previous line, running at high efficiency while being energy-saving with an Energy Star rating. Additionally, this could be the air purifier with lowest noise level, making it perfect for even bedroom.

The Levoit Core 600s uses an advanced laser sensor for more accurate and quicker result of indoor air quality index, within only 30 seconds. Based on the result, the Levoit Core 600S will monitor the right fan speed for your home.

Here is the pros/cons of Levoit Core 600S:

PROS


  • Large Room coverage: 700 square feet
  • Stunning performance rating for the price
  • Very quiet
  • Low energy consumption
CONS


  • Would be nice with casters

3) AIRMEGA 400S – Top Rated Smart Air Purifier, Rank A+

 Previously in our list:   AIRMEGA 400S.

As the current flagship of Coway, we have high expectations for the AIRMEGA 400S. Indeed, this air purifier maintains an excellent level of performance and functionality.

AIRMEGA 400S is a big room air purifier that can cover an area of up to 1560 square feet. Although the CADR is not stated in the documentation for this AIRMEGA, after doing several extensive testing, Breathe Quality recorded an underrated CADR of 340 Dust/ 350 Smoke/ 400 Pollen. This CADR specs is not sufficient for a large room coverage of 1560 sq ft.

In our air purifier ranking list, AIRMEGA 400S ranks A+ with an A in performance, together with its little brother AIRMEGA 300S. However with its high CADR rating, the AIRMEGA 400S secures position 3 in our list of the best large room air purifiers.

best large room air purifier

Just like Blueair, Coway is now combining their air filters to become one for better installation. In this AIRMEGA 400S machine, we will have:

  1. Pre-filter – A powerful washable pre-filter is available to help you capture large objects of contaminants.
  2. Max2 filter – A combination of both Activated Carbon Filter and True HEPA filter, this filter can both capture up to 99.97% of airborne particles 0.3 microns and reduce more than 99 percent of volatile organic compounds and reduces fumes such as NH3 and CH3CHO.

AIRMEGA 400S is also the top-rated smart air purifier at the time, thanks to its Smart Enabled Feature. This brand has an exclusive Eco Mode that automatically adjusts the fan speed based on the air quality, therefore conserving electricity.

Here is the pros/cons of AIRMEGA 400S:

PROS


  • Large Room coverage: 1560 square feet
  • Amazing performance rating
  • Energy-saving
  • Well-built with highest quality materials
  • 5-year warranty
CONS


  • High cost filter replacement
  • Low CADR for the room coverage

4) Airdog X8 – Filterless to save Annual Cost, Rank A

 Previously in our list:   Medify MA-112.

Airdog X8 is the flagship of Airdog USA, or Silicon Valley Air Expert company. With an unmatched fan power, together with no need of True HEPA filter, the Airdog X8 shows that it can win our list of the best large room air purifier.

Airdog X8 is suggested for a room size of 1000 square feet by the manufacturer, and with the CADR rating of 470 cfm in general, this is one of the best air purifiers for fan power we’ve ever tested.

In our air purifier ranking list, Airdog X8 ranks A with an A- in performance.

best large room air purifier

Unlike other air purifiers in this list with only mechanical air filters, the Airdog X8 uses ionizer to replace HEPA filter in trapping airborne impurities.

  1. Pre-filter – The polluted air must pass through a pre-filter screening, where it traps large particles of pollutants like hair and dander. It is washable and permanent.
  2. Ionizer – The ionic field is created on the surface of the generator wires (or emitter wires) and also the main filtration method of the Airdog X8. It can destroy even the 0.0146 microns ultra-fine particles, such as bacteria, germs and viruses. In addition, it is also effective in removing the pet dander, pollen, dust and other particles that are larger than 0.3 microns.
  3. Collecting Plate – While not being a layer of protection, the collecting plate is necessary to collect the harmful particles inside. These heavy-duty but dishwasher-safe plates can easily be cleaned, saving you from expensive replacement filters.
  4. Composite Catalyst – The last filter of this Airdog X8 is actually an Activated Carbon filter, which removes odors, smoke and chemicals. This is also where the Airdog X8 remove the ozone emission, to guarantee the cleanest air quality for your home.

The Airdog X8 wants to be standout in the marketplace with full of HEPA air purifiers, relying only on its powerful ionizer to deal with airborne ultra-fine particles, from dust, dust mites, pollen, pet dander to even bacteria, germs and viruses. We’ve tested it rigorously, just to confirm that it has great performance.

Together with its raw power, the Airdog X8 features high-end smart features, including Smart Sensor. This air purifier automatically calculates the amount of particles in the air, then the Auto Mode simply adjusts its speed according to the current air quality level.

Here is the pros/cons of Airdog X8:

PROS


  • Large Room coverage: up to 1000 square feet
  • Great performance
  • Great additional features
  • Quiet operation

CONS


  • No CARB certification yet
  • Lacks of casters

5) Dyson TP04 – Unique Design, Rank A

 Previously in our list:   Dyson TP04.

The third position, again, sees a new shift for the Dyson TP04 – the flagship of the Dyson Pure Cool Tower series by Dyson. The British leading innovator in fan and air purifier market has released the fourth generation of their signature fan-air purifier combination

While the air purifier isn’t tested by AHAM for room coverage, we believe it can cool and clean an area of at least 700 square feet.

To deal with such large room, the Dyson TP04 has an unchallenged CADR rating of 600 to 770 cfm at maximum. The air purifier can deliver up to 93.5 gallons of purified air per second, thus win position 5 in the list for the best large room air purifiers. Moreover, the Dyson air purifier doesn’t have ACH rating, because it will continuously blow the air around your room, thanks to its cooling fan function.

In our air purifier ranking list, Dyson TP04 ranks A, with an A- in performance.

best large room air purifier

Not only has an excellent fan power, the Dyson TP04 invents a high-quality air filtration system which passed many rigorous tests to meet the highest requirements.

  1. True HEPA filter – With the glass HEPA filter, the Dyson TP04 is able to capture 99.97% of all airborne particles as small as 0.3 microns, including pollen, bacteria and pet dander.
  2. Activated Carbon filter – Removes household odors and gases such as formaldehyde, benzene and nitrogen dioxide.

Apart from the superior efficacy of its air filtration technology, the Dyson TP04 is surprisingly silent for a fan of this size. You will be able to use the gadget without being concerned about the noise level.

Most importantly, the Dyson TP04 is a real Smart air purifier, as it can be controlled via Wi-Fi or Alexa. With the Smart Sensor, the Dyson TP04 can clean the room automatically with precision.

Here is the pros/cons of Dyson TP04:

PROS


  • Large Room coverage: 700 square feet
  • Great performance
  • Cooling power is really cool
  • High-end features
  • Unique design

CONS


  • Only 2-year warranty
  • The air filtration system isn’t the best

6) Blueair Pro XL – Highest Power and Price, Rank B

The old champion of Blueair once again comes back as one of the best air purifiers for large rooms. Blueair Pro XL is still the air purifier with the highest fan power, resulting in highest performance at a ridiculously high price. However, at rank B in our air purifier ranking list, the Blueair Pro XL show its prominence with an A+ in performance

The Blueair Pro XL comes with an AHAM’s CADR of 950 Dust/ 800 Smoke/ 900 Pollen (cfm), which is the highest spec we’ve tested. It is recommend for just 1180 square feet, but we believe that nothing can beat it at 2000 square feet.

best large room air purifier

Blueair Pro XL is an old device at the moment, so it only features the classic air filtration system made by Blueair years ago.

  1. Particle Filter/ SmokeStop Filter – Choose between the 2 filter selections. One is the Particle Filter, the optimal choice for removing particle pollutants such as bacteria, viruses, pet dander, dust and pollen. Or the SmokeStop Filter to get rid of gaseous pollutants, for example Volatile Organic Compounds (VOCs, such as formaldehyde), tobacco smoke and particles.
  2. Carbon+ Filter – To add an extra protection against gaseous pollutants.

The old HEPASilent technology of Blueair Pro XL allows it to run quiet and energy-saving, but still achieve high performance. In fact, the Blueair Pro XL can capture 99.97% of down to 0.1 microns pollutant particles.

Evolved from the Pro L, the Blueair Pro XL gets its own Blueair Pro AIM to monitor the fan speed accordingly to the environment. However, it lacks most of basic features.

Here is the pros/cons of Blueair Pro XL:

PROS


  • Large Room coverage: up to 2000 square feet
  • Highest performance in test
  • Well-built with highest quality materials
  • 5-year warranty
CONS


  • Lacks of basic features
  • Very, very expensive
  • Low filter’s life time

7) AeraMax Professional 4 – Huge and Powerful, Rank B-

AeraMax secures the position 7 in our list of the best large room air purifier with the flagship AeraMax Professional 4, which competes directly with the aforementioned Blueair Pro XL. In our air purifier ranking list, AeraMax Professional 4 ranks B- with an A in performance.

With less fan power than the competitor at around 440 cfm in general, the AeraMax Professional 4 is suggested to cover only 800 square feet. Again, we believe its power can deal with any rooms up to 1400 square feet.

best large room air purifier

AeraMax Professional 4 doesn’t compromise at anything, bringing the most patented 5-stage air cleaning system from AeraMax.

  1. Pre-filter – AeraMax Professional 4 detaches the pre-filter out of the carbon filter, so the carbon filter can keep working effectively. The pre-filter can capture large particulates like dust and hair, and needs to be replaced after 6 months.
  2. Activated Carbon Filter – The carbon filter works independently to capture high odors or Volatile Organic Compounds (VOCs).
  3. True HEPA filter – Next, all airborne contaminants must rest in the True HEPA filter of this air purifier, with a high efficiency of trapping 99.97% of any particles as small as 0.3 microns like pollen, ragweed and other allergens, viruses, germs, dust mites, mold spores, and pet dander.
  4. AeraSafe Antimicrobial Treatment – The built-in protection right in the surface of its True HEPA filter, to prevent the growth of odor-causing bacteria, mildew, and fungi.
  5. PlasmaTrue Technology – This is one kind of ionizer, which creates an ionized field to help safely remove airborne pollutants. Can be switched on/off.

The Professional line of AeraMax upgrades the air filtration system from its own Commercial line to the max degree. AeraMax Professional 4 uses only big and high-quality air filters so it can deal with the majority of airborne pollutants.

AeraMax Professional 4 has its own Smart Sensor in the name of EnviroSmart technology. It is highly accurate and quick in detecting the indoor air quality’s change.

However, the AeraMax Professional 4 has a very expensive price tag, just like its closest competitor – the Blueair Pro XL.

Here is the pros/cons of AeraMax Professional 4:

PROS


  • Large Room coverage: up to 1400 square feet
  • Powerful air filtration system
  • Patented EnviroSmart technology
  • Mountable on wall
CONS


  • Low filter’s life time
  • Very, very expensive

8) IQAir GC MultiGas – Old Champion, Rank B-

IQAir is a true giant in the air purifier industry, the only to claim as the World’s Best HEPA Air purifier, with the foundation to be 50 years ago. This brand is only dedicated to bringing out the luxury high-range air purifiers. IQAir GC MultiGas is currently the most powerful air purifier for large room.

The air purifier has the highest-quality air filtration system and a powerful fan to keep your room clean fast and effectively. The IQAir GC MultiGas has a coverage area of up to 1125 square feet.

To top up with this high CADR, IQAir GC MultiGas loads 5x air changes per hour (ACH).

In our air purifier ranking list, IQAir GC MultiGas ranks B-, with an A in performance.

best large room air purifier

However, room coverage and fan power is just one criteria to decide the champion. The bottom line is the perfect performance rating of IQAir GC MultiGas. IQAir proudly claim to be the #1 Air purifier for smoke, odors and MCS not without a reason. Let’s have a look in the 4-stage Air Cleaning system below:

  1. HyperHEPA filter – You will have a powerful HyperHEPA H11 pre-filter. This True HEPA filter is effectively capture 99% of particles down to 0.3 microns, and 95% of particles as small as 0.003 microns.
  2. Cartridge-based activated carbon filter – This filter can remove VOCs and odors effectively because it is made with the highest quality ABS plastics.
  3. Cartridge-based chemisorption – This stage destroys harmful chemicals, such as formaldehyde by an oxidation process. Any kinds of smoke or VOCs pass through these two cartridge-based filter will be absorbed completely.
  4. Post-filter sleeve – A post-filter sleeve wraps each gas cartridge to prevent media dust from being released back into the air.

Because the IQAir GC MultiGas is constructed with high-quality materials, you need not be concerned. The IQAir’s patented 3D UltraSeal leak-proof construction prevents air from leaking back into the room without passing through the GC MultiGas filters.

Here is the pros/cons of IQAir GC MultiGas:

PROS


  • Large Room coverage: 1125 square feet
  • World class fan power
  • Well-built with highest quality materials
  • 5-year warranty
CONS


Review: IQAir GC MultiGas Review.

The IQAir GC MultiGas is primarily used to combat smoke, smells, volatile organic compounds (VOCs), formaldehyde, and other pollutants. If you’re concerned about common household dust, dust mites, pollen, or pet dander, you should consider the IQAir HealthPro Plus. This air purifier is $400 less expensive than the GC MultiGas model, but features an upgraded HyperHEPA filter from H11 to H13. Having said that, IQAir HealthPro Plus is capable of removing 99.97% of ultra-fine particles as tiny as 0.3 microns and 95% of particles as small as 0.003 microns. This, we feel, is the finest HEPA filter available at the present. In our air purifier ranking list, the IQAir HealthPro Plus ranks B-, too.

9) Blue Pure 121 – The most powerful air purifier for under $500

 Previously in our list:   Blue Pure 121.

It is normal to find 2 air purifiers from Blueair in any lists of best large room air purifiers, because the company is really dedicated in making air purifiers with high fan power. The Blue Pure 121 is only suggested for a room size of 620 square feet, but we all believe it is able to clean a much larger room with ease.

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

best large room air purifier

Blue Pure 121 still features the exclusive Blueair air purification system as below:

  1. Pre-filter – The fabric pre-filter of Blue Pure 121 is outside the air purifier and can catch the large particles. This pre-filter is washable and/or vacuumable.
  2. Particle filter – Instead of using a True HEPA filter, Blue Pure 121 uses a polypropylene fibers filter to help capture 99% of all allergens like dust, dust mites, pet dander, pollen and fungi (HEPA technology).
  3. Activated Carbon Filter – The Activated Carbon filter is added inside the Particle filter and effective against smoke, odors, gases and VOCs.

Though the Blue Pure 121 is a simple air purifier without any smart features, it is simply the most powerful air purifier for under $500, which is widely confirmed by many reputable air purifier reviewers in the world. It is rated by the Association of Home Appliance Manufacturers (AHAM) with a CADR rating of 400 Dust/ 400 Smoke/ 400 Pollen (cfm).

10) Austin Air HealthMate Plus (HM450) – Best Medical Grade for Large Room

 Previously in our list:   Austin Air HealthMate Plus.

With the title of “The only Clinically Proven, Medical Grade Air Purifier”, Austin Air is always the first choice when it comes to choosing the best large room air purifier. If you could afford a high-range budget machine, Austin Air is the brand that is most frequently mentioned.

Their Austin Air HealthMate Plus is notable for large room coverage of 1500 square feet.

We can easily measure the fan power of this Austin Air flagship with a 5X ACH and 400 cfm CADR. In our air purifier ranking list, Austin Air HealthMate Plus ranks C+, with an A+ in performance.

best large room air purifier

One advantage for Austin Air HealthMate Plus is their medical grade 4-stage filter.

  1. Pre-filter – To remove any large objects of pollutant particles like pet hair, human hair or large dust. This pre-filter is washable and permanent.
  2. Medium Particle Pre-filter – Just like Rabbit Air MinusA2, Austin Air HealthMate Plus can remove molds, spores and pollen from this pre-filter.
  3. Activated Carbon filter – A 15-lb Activated Carbon, Potassium Iodide Impregnated Carbon and Zeolite to help remove VOCs, formaldehyde, benzenes, chemicals, gases and odors.
  4. True HEPA filter – With twice the pre-filter, the True HEPA filter will only need to capture the tiniest particles. Using a Medical Grade 60-square-ft True HEPA filter, Austin Air Healthmate Plus is a real deal to any contaminant problems in your large room.

The sound produced by this Austin Air HealthMate Plus is somewhat low on the low setting but quite loud on the high level. It is advised that this air purifier be operated on the low setting more frequently.

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

PROS


  • Large Room coverage: 1500 square feet
  • Impressive fan power
  • Top-notch performance rating and air filtration process

Best Large Room air purifiers in 2022 Buying Guide

On this page, you’ll discover all the information you need to make an informed decision on the top-rated air purifier to purchase for your large room. The most beneficial purchasing advise we can provide is to check the area (big room coverage) that your air purifier can cover. Because if you utilize a 200 square foot air purifier in a 500 square foot space, even at its highest ACH rating (Air changes per hour), your air purifier will be unable to filter the room air. As a result, the life of your air purifier’s filter is reduced, as is energy consumption. We’re guessing you realize why you need to properly research the best air purifier for your huge space.

To guarantee that your air purifier works properly, just verify the square footage rating of the equipment you’re considering purchasing. Then, compare it to the size of the room in which it will be used. If the square footage rating of the gadget is equal to (=) or larger than (>) the size of the targeted room, it is an excellent choice. If not, DO NOT BUY THIS ITEM.

If you need a complete buying guide for your large room air purifier, for example you want to know about the technical specifications like ACH, CADR, you can read more here.

We hope our best large room air purifier list will help you choose your suitable air purifier in 2022. Thank you!
