With a Swedish design and German-engineered architecture, the Blueair Pro XL can achieve the top-notch performance rating. We could expect a high efficiency of trapping 99.97% any airborne allergens as small as 0.1 microns, such as dust, dust mites, pet hair, pet dander, mold spores, bacteria and viruses… To deliver such high power, the Blueair Pro XL packs inside the Blueair certified Particle air filter – a combination of the high-quality True HEPA filter with the electrostatic filtration.

The fan power of this Blueair Pro XL is unmatched by any air purifiers available right now. The AHAM rated room coverage of the Blueair Pro XL is 1180 square feet, and it can run at a brilliant CADR rating of 950 Dust/ 800 Smoke/ 900 Pollen (cfm). This machine can purify the air once every 12 minutes, and within the first 12 minutes, it could be able to clean any allergens and smoke in your office.

On top of that, the HEPASilent Technology can guarantee that the Blueair Pro XL only operate as silent as possible. The noise level of 32 decibels (db) at the lowest setting is even lower than the standard library’s noise. You won’t hear anything while using it for sure.

Finally, Blueair Pro XL has integrated its own Smart Sensor, which can detect the real-time indoor air quality to adjust the fan speed automatically. You won’t need to run air purifier manually anymore. This is the high-end feature which is only available in the top-class air purifiers.

2) Austin Air HealthMate Plus (HM450) – Best Medical Grade Air Purifier for Office

 Previously in our list:   Austin Air HealthMate Plus.

Expert tips: If you demand a medical-verified air purifier, Austin Air is a best brand for you.

Austin Air is proud to be chosen by the U.S government as the top air purifier brand. Their Austin Air HealthMate Plus is the necessary upgrade to the previous Austin Air HealthMate, adding more protection against the Volatile Organic Compounds (VOCs), formaldehyde, benzenes, chemicals, gases and odors. It seems the title of “The only Clinically Proven, Medical Grade Air Purifier” from Austin Air is not a bluff.

  • Area coverage: 1500 square feet
  • The silence: Good at lowest setting, 40 – 64.5 decibels (db)
  • The size (H x W x D): 23 x 14.5 x 14.5 inches
  • Item weight: 40 lbs, 4 casters
best air purifier for office

The Austin Air HealthMate Plus (or Austin Air HM450) is a high-range air purifier, which is clearly expensive. However, for that money you’re getting an extraordinary spec list, including the 60 square feet True HEPA filter and 15 lbs of Activated Carbon filter. Its True HEPA filter is Medical Grade certified, and covered with double physical pre-filter to be extremely effective at removing particles in the air. We measured the efficiency is as high as 99.97% for any pollutant particles down at 0.3 microns in size.

The improvement on the Austin Air HealthMate Plus’s Activated Carbon filter is part of the reason they rank so highly in our list. This company has added the Potassium Iodide Impregnated Carbon to enhance the filtration against many types of Volatile Organic Compounds (VOCs) and even formaldehyde.

Moreover, with a large room coverage of 1500 square feet under the hood, Austin Air HealthMate Plus is impressive with its fan power. The CADR rating of 400 cfm is powerful, and this air purifier can clean your room as often as 12 minutes.

But there is one downside, the Austin Air HealthMate Plus is quite noisy at the highest setting. To keep the noise level as low as possible, you should run this air purifier before working 30 minutes, and then switch down to the lowest fan speed. The noise level of 40 decibels (db) is exactly the library noise level, and you can work without trouble beside this Austin Air HealthMate Plus.

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


  • Top-notch performance rating
  • High quality Air filtration process
  • Impressive fan power
  • 360 Degree Air intake
  • Well-built with highest quality materials
  • Extra large room coverage
  • Has 4 casters
  • 5-year warranty

  • Lacks of Smart features
  • Low CADR for the room coverage
  • Too noisy at highest setting

3) Airpura V600 – Best Room Coverage for Extra-Large Office

 Previously in our list:   Airpura T600.

The Canadian air purifier brand – Airpura is the perfect device for any office settings. Their central air system can connect the Airpura V600 with your entire office. And you don’t need to worry about the investment, because the central air system only recirculates your indoor air instead of heating or cooling your outdoor air, which will result in energy savings for you.

Other than that, you can keep the Airpura V600 with 4 large built-in casters to run in your office as well.

  • Area coverage: 2000 square feet
  • The silence: Whisper Quiet, 28 – 62 decibels (db)
  • The size (H x W x D): 23 x 15 x 15 inches
  • Item weight: 52 lbs, 4 casters
best air purifier for office

The main core of the Airpura V600 is a 40-sq-ft True HEPA filter, which is covered by a poly 2PK pre-filter to capture 99.97% of airborne particles as small as 0.3 microns in size. You can choose to upgrade this True HEPA filter to further enhance the efficiency of your indoor air filtration.

The Airpura V600 is the recommendation of this brand for protection against wildfire smoke, so you will have an 18 lbs Activated Carbon filter, along with the Potassium Iodide as featured in the Austin Air HealthMate Plus. Any harmful airborne chemicals and VOCs will be found and eliminated eventually with this Airpura V600.

The AHAM verified room coverage of this Airpura V600 is 2000 square feet. You will get a great CADR rating of 560 cfm, so your Airpura V600 can clean the office really fast. For the air changes per hour, this air purifier will clean your office every 12 minutes.

With an identical design as the Austin Air HealthMate Plus, the Airpura V600 handles the noise level a lot better. The lowest fan speed of this air purifier is only 28 decibels (db), and you will hardly hear any sound from the device when operating.

Here is the pros/cons of Airpura V600:


  • Great performance rating with True HEPA filter
  • Unmatched fan power
  • 360 Degree Air intake
  • Well-built with highest quality materials
  • Has 4 casters
  • Extra large room coverage – 2000 square feet

If your office restricts smoking and you still need an air purifier, Airpura has specialized the air purifiers for specific purposes, but stays the same room coverage of 2000 square feet. For example, Airpura R600, Airpura H600 and Airpura UV600 are all the powerful True HEPA air purifiers to capture 99.97% of airborne particles as small as 0.3 microns.

Expert tips: For True HEPA filters, Airpura called them HEPA 600RVHU filter. Fun fact is, 600 (R, H, V, UV) are 4 types with True HEPA filter, for example the HEPA-type 600CT is for Airpura 600 (C, T).

Here is the family of Airpura’s air purifiers for you to decide.

4) IQAir HealthPro Plus – Best True HEPA filter for Office

 Previously in our list:   IQAir HealthPro Plus.

The IQAir could be the air purifier brands with the longest history. They are also famous for creating the high-quality “Swiss Made” air purifiers, for example this IQAir HealthPro Plus. As an educational partner with American Lung Association, we believe that the quality of the flagship from IQAir is beyond any imagination.

  • Area coverage: 1125 square feet
  • The silence: Very quiet, 22 – 57 decibels (db)
  • The size (H x W x D): 28 x 15 x 16 inches
  • Item weight: 35 lbs, optional casters
best air purifier for office

Instead of using the normal True HEPA filter, IQAir HealthPlus Pro makes use of the special HyperHEPA, a verified air filter to capture 99.5% of particles down to 0.3 microns and even 99% of 0.003 microns. Protected by a PreMax air filter, the IQAir HealthPlus Pro doesn’t need any ions or ozone to maintain such high efficiency of purifying air.

Moreover, IQAir HealthPlus Pro has a granulated Activated Carbon filter, with pelletized chemisorption inside. It is only 5 lbs, which is no match against the Airpura V600 or Austin Air HealthMate Plus, but is still effective against any types of VOCs, smoke, odors and other harmful chemicals.

For the fan power, the IQAir HealthPlus Pro is also excellent with a high CADR rating of 300 cfm, in an extra large room coverage of 1125 square feet. It will clean your office as often as possible every 12 minutes, for a total of 5 times per hour.

Thanks to the aerodynamics fan design and the addition of 8 shock absorbers, IQAir HealthPlus Pro only operates at 22 decibels (db) for the lowest setting. Do you know that 22 db is just only the noise level of rustling leaves, and we bet most of Breathe Quality’s audiences could hear any sound from this air purifier.

Here is the pros/cons of IQAir HealthPro Plus:


  • Top-notch performance rating
  • Well-built with highest quality materials
  • Remarkable Technology and Fan Power
  • Impressive quiet
  • 5-year warranty

  • Activated Carbon filter is not good as IQAir GC MultiGas

The room coverage of Alen BreatheSmart 75i, like any devices in this list of best air purifiers for office, is huge – 1300 square feet. However, it seems the CADR rating is not so good. With only 347 cfm, you will need more time for the Alen BreatheSmart 75i to clean such large room.
