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.

  • 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.

UPDATED: We have updated our list of best large room air purifiers on 12/15/2021, as a result of a 3-month lab test. In Breathe Quality, we keep updating our posts whenever possible, and this time we will add the latest version of Dyson Pure Cool Tower in the list of best large room air purifiers, as well as welcome the Blueair Classic 605 and Blue Pure 121 back in the game. Also, we finished testing the Medify MA-112 and we believe this air purifier deserves a slot in our 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) IQAir GC MultiGas – Our 2022 Champion

 Previously in our list:   IQAir GC MultiGas.

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.

So why did Breathe Quality award IQAir GC MultiGas the gold medal?

It has the highest-quality air filtration system and a powerful fan to keep your room clean fast and effectively. The IQAir GC MultiGas is the champion of big room air purifiers, with a coverage area of up to 1125 square feet. Notably, the IQAir GC MultiGas is equipped with a strong New Edition Fan. GC MultiGas can now achieve a Clean Air Delivery Rate (CADR) of 300 cfm. To top up with this high CADR, IQAir GC MultiGas loads 5x air changes per hour (ACH).

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
  • Perfect air filtration system
  • Well-built with highest quality materials
  • 320° air distribution
  • Very quiet
  • Low power consumption
  • 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.

2) Blueair Classic 605 – Our 2022 Runners-up

 Previously in our list:   Blueair Pro XL.

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.

As the runners-up of best large room air purifiers list, Blueair Classic 605 can cover an extra large room of 775 square feet.

However, do not be fooled by the reduced room coverage; the Blueair Classic 605 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 500 Dust/ 500 Smoke/ 640 Pollen (cfm) and an ACH rating of 5X, which is even higher than the champion IQAir GC MultiGas.

best large room air purifier

In terms of power, Blueair Classic 605 isn’t as powerful as the previous Blueair Pro XL, but its high fan power nearly reaches the flagship of Blueair Pro series for only a third of the price. And the flagship of Blueair Classic series is using an all-in-one air filter as below.

  1. Particle Filter/ SmokeStop Filter – You can choose from the Particle Filter with the power to capture 99.97% of pollutants such as pollen, dust, pet dander, mold spores, viruses and bacteria down to 0.1 microns. Otherwise, you can pay more for SmokeStop Filter, which is most likely the combination of True HEPA filter and Activated Carbon filter.

After months of using the Blueair Classic 605, we believe this is the air purifier with most value for money you can get from the famous Blueair. 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.

Here is the pros/cons of Blueair Classic 605:

PROS


  • Large Room coverage: 775 square feet
  • Most powerful fan power in the world
  • World class performance rating and amazing air filtration
  • Well-built with highest quality materials
  • 5-year warranty
CONS


  • Bulky size and heavy
  • High power consumption

3) Dyson TP04 – Our 2022 Third place

 Previously in our list:   Oransi Erik 650A.

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 clear the Oransi Erik 650A out of the list of 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.

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, just like the Blueair Classic 605. Moreover, the flagship tower air purifier of Dyson has Smart Sensor, so it 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

Review: Dyson TP04 Review.

4) 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. This fan power is still extremely powerful for an air purifier, being double the CADR of the best low-range air purifiers like Coway AP-1512HH or Winix HR900.

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
  • 360° air intake
  • Well-built with highest quality materials
  • 5-year warranty
CONS


  • Lack of Smart features
  • Low CADR for the room coverage
  • Too noisy at high setting

Review: Austin Air HealthMate Plus Review.

5) AIRMEGA 400S – Top Rated Smart Air Purifier

 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.

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
  • 360° air intake
  • Well-built with highest quality materials
  • 5-year warranty
CONS


  • App receives many negative reviews
  • High cost filter replacement
  • Low CADR for the room coverage

Review: AIRMEGA 400S Review.

6) Medify MA-112 – The best flagship on a budget for large rooms

 Previously in our list:   Dyson DP04.

With an unmatched fan power, together with a H13 True HEPA filter, the Medify MA-112 officially wins a slot in our list of the best large room air purifiers. This is the flagship of Medify Air, packing with the internal power that you could expect from a flagship, with much lower price than things like the IQAir GC MultiGas or Blueair Classic 605.

Medify MA-112 is suggested for a room size of 1200 to 2400 square feet by the manufacturer, and with the AHAM’s CADR rating of 400 Dust/ 450 Smoke/ 450 Pollen (cfm), this is one of the best air purifiers for fan power we’ve ever tested.

best large room air purifier

Unlike other air purifiers above in the list with only mechanical air filters, the Medify MA-112 retains the signature air filtration system from its popular brother – the Medify MA-40.

  1. Pre-filter – A layer of pre-filter covers the True HEPA filter, to prolong the life time of the core filter, by trapping the large objects of pollutants like fur, hair and large dust.
  2. True HEPA filter – The True HEPA Filter (graded H13) that captures 99.97% of as small as 0.3 microns allergens, virus particles, pollen, mold and fungi particles.
  3. Activated Carbon filter – Uses substantial carbon filter with carbon pellets to remove toxic odors and formaldehyde.
  4. Ionizer – Produces negative ions to charge particles and trap them inside the unit. Can be switched on/off. Activated Carbon filter – Removes household odors and gases such as formaldehyde, benzene and nitrogen dioxide.

With these traits, the Medify MA-112 easily beats the Dyson DP04 in every versus test for air purifying. It can clean a large room in no time, and with the highest efficiency you could expect from an air purifier that normally costs you $200 higher.

Furthermore, the Medify MA-112 has a Smart Sensor that detects changes in indoor air quality and adjusts the fan speed appropriately.

7) Alen BreatheSmart 75i – Best for Customer Service

 Previously in our list:   Alen BreatheSmart.

Alen is the first and the best air purifier brand that delivers a Forever Warranty – a policy to guarantee the rights of their customers, as well as show the absolute confidence in their products. After many years of manufacturing the HEPA-type devices, finally we have a True HEPA flagship from Alen – the Alen BreatheSmart 75i.

With a coverage of 1300 square feet, Alen BreatheSmart 75i is the best air purifier for large rooms from this company.

Also, the fan power is strongly improved from the predecessor, as Alen BreatheSmart 75i has a CADR rating of 347 cfm, and can exchange the air 5 times per hour.

best large room air purifier

Now, Alen BreatheSmart 75i can boast about its powerful 3-stage air cleaning system, with the core of a great True HEPA filter. In addition, the Alen BreatheSmart 75i still combines its mechanical filters with the ionizer to push the limit of trapping 99.97% of allergens as small as 0.3 microns. You can select one from the 4 different True HEPA filters, depending on your demand.

  1. Pure – The standard True HEPA filter of Alen BreatheSmart 75i, which is able to capture 99.97% of as small as 0.3 microns pollutant particles such as dust, dust mites and pollen.
  2. Fresh – The next level HEPA filter will improve the first Pure, with the addition of Activated Carbon filter, to deal with the household odors and chemicals. This air filter is necessary for people who are sensitive to VOCs.
  3. Pet – Without the Activated Carbon filter, the Pet air filter uses the Alen’s patented Molecular Conversion Powder to ensure  heavy pet odors are destroyed at a molecular level.
  4. Heavy Odor – Alen BreatheSmart 75i changed the Molecular Conversion Powder in the Pet air filter to make the new Heavy Odor filter, which can remove the household odors from smelly kids/teenagers, kitchen garbage, and other everyday activities.

8) Levoit LV-H134 – The Best Bang for the Buck

 Previously in our list:   Levoit LV-H133.

The air purifier from Levoit proves that this brand can really make the air purifiers targeting large rooms (over than 500 sq ft). In the most affordable list of best large room air purifiers, we have a $400 Levoit LV-H134 with a room coverage of 710 square feet, larger than the previous Levoit LV-H133.

This air purifier upgrades to a CADR of 312 cfm from the previous 135 cfm of Levoit LV-PUR131. We believe that this improvement for fan power will make Levoit LV-H134 one of the top-notch performers in this low-range segment.

best large room air purifier

As a large room air purifier, Levoit LV-H134 has no different air filtration system compared with previous models. We still have a 3-stage air filtration system as below:

  1. Pre-filter – This nylon 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 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 – This Activated Carbon filter efficiently adsorbs smoke, odor, formaldehyde, VOCs and benzene.

Using a new technology, Levoit LV-H134 is more stable and more silent than even the air purifier for bedroom LV-H132. Also, this air purifier is one of the lowest energy-consuming air purifiers.

The Levoit LV-H134 utilizes the advanced laser sensor, for more accurate and quicker result of indoor air quality index, within only 30 seconds. Based on the result, the Levoit LV-H134 will monitor the right fan speed for your home.

Here is the pros/cons of Levoit LV-H134:

PROS


  • Large Room coverage: 710 square feet
  • Stunning performance rating
  • Solid-built
  • Very quiet
  • Low energy consumption
CONS


  • There is a bump in the price from previous models
  • Still the same CADR rating from Levoit LV-H133

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

 Previously in our list:   Biota Bot MM608I.

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.

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).

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!
