The Blueair Pro XL achieves the best performance rating thanks to its Swedish design and German-engineered architecture. We may anticipate a high effectiveness of 99.97 percent catching allergens as small as 0.1 millimeters in the air, including as dust, dust mites, pet hair, pet dander, mold spores, germs, and viruses… To achieve this level of performance, the Blueair Pro XL incorporates a Blueair-certified Particle air filter — a hybrid of a high-quality True HEPA filter and electrostatic filtering.

The Blueair Pro XL’s fan power is unequaled by any other air purifier on the market today. The Blueair Pro XL has an AHAM room coverage rating of 1180 square feet and a superb CADR rating of 950 Dust/800 Smoke/900 Pollen (cfm).

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 honored to have been named the best air purifier brand in the United States by the federal government. Its Austin Air HealthMate Plus is an improvement to the original Austin Air HealthMate, providing further protection against VOCs, formaldehyde, benzenes, chemicals, gases, and smells. According to Austin Air, the title “The only Clinically Proven, Medical Grade Air Purifier” is not a bluff.

  • The size (H x W x D): 23 x 14.5 x 14.5 inches

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 enhancements to the Austin Air HealthMate Plus’s Activated Carbon filter contribute to its excellent ranking on our list. This manufacturer incorporated potassium iodide impregnated carbon to improve filtration against a wide variety 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.

However, there is one drawback: at its maximum setting, the Austin Air HealthMate Plus is rather noisy. To reduce the noise level to a minimum, operate this air purifier for 30 minutes before to working and then switch to the lowest fan speed. The noise level of 40 decibels (db) is same to that of a library, and you may work peacefully next to 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

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. Its central air system can connect the Airpura V600 with your entire office. And you won’t have to worry about the investment, since the central air system will only circulate your inside air, rather than heating or cooling the exterior air, resulting 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

The Airpura V600‘s primary filter is a 40-square-foot True HEPA filter that is encased in a poly 2PK pre-filter. This filter captures 99.97 percent of airborne particles as tiny as 0.3 microns in size. You may update this True HEPA filter to increase the effectiveness of your indoor air filtration system even more.

This brand’s choice for protection against wildfire smoke is the Airpura V600, which has an 18 pound Activated Carbon filter in addition to the Potassium Iodide included in the Austin Air HealthMate Plus. With this Airpura V600, any dangerous airborne pollutants and VOCs will be detected and finally eradicated.

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.

The Airpura V600, which shares the same architecture as the Austin Air HealthMate Plus, is significantly quieter. This air purifier’s lowest fan speed is only 28 decibels (db), and it operates quietly.

  • Unmatched fan power
  • 360 Degree Air intake
  • Well-built with highest quality materials
  • Has 4 casters

If your office prohibits smoking but you still want an air purifier, Airpura has tailored its 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. It is 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

Rather of employing the standard True HEPA filter, IQAir HealthPlus Pro utilizes the HyperHEPA, a certified air filter capable of capturing 99.5 percent of particles as small as 0.3 microns and even 99 percent of particles as small as 0.003 microns. Protected by a PreMax air filter, the IQAir HealthPlus Pro does not require ions or ozone to operate at such a high level of air purification efficiency.

Moreover, IQAir HealthPlus Pro has a granulated Activated Carbon filter that contains pelletized chemisorption. Although it weighs less than the Airpura V600 or Austin Air HealthMate Plus, it is nevertheless effective against all forms of VOCs, smoking, smells, and other dangerous substances.

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.

IQAir HealthPlus Pro runs at the lowest setting of 22 decibels (db) due to the aerodynamic fan design and the inclusion of eight shock absorbers. Did you know that 22 db is the noise level produced by rustling leaves? We’re guessing that the majority of Breathe Quality’s audience would be able to hear any sound produced by 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

Finally, we are pleased with the AIRMEGA 400S’s incredibly silent functioning. The lowest recorded noise level is 22 decibels (db), which is comparable to the sound of rustling leaves. You can work productively in the workplace without being bothered by the AIRMEGA 400S’s unpleasant noise.

6) Alen BreatheSmart 75i – A Forever Warranty for your Air Purifier

Alen is the first and only brand that has enough confidence to provide the lifetime warranty – the highest warranty policy to back up any products.

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.

Even having the brand’s highest powerful fan inside, the Alen BreatheSmart 75i works at a whisper-quiet 25 decibels (db) on the lowest setting.
