Then, there’s a medium air filter that traps large allergens and dust particles in the air. A BioGS HEPA filter then captures up to 99.97% of airborne particles as small as 0.3 microns, including allergens, pollen, and dust mites.
Afterward, you get the choice between a Germ Defense, Pet Allergy, Toxin Absorber, or Odor Remover filter. Finally, an activated carbon filter gets rid of unwanted odors while a negative ion generator further freshens the air without emitting harmful ozone.
The MinusA2 offers slightly less air coverage than other air purifiers on this list, but its maximum room coverage of around 800 sq. ft. would still be enough for a medium to a large office.
The air purifier's motor operates at 5 different speeds, with a 25.6 to 51.3 dB noise level. This means that even on higher fan settings, the air purifier is hardly noticeable and won't cause any office distractions.
I really appreciate how this unit can either stand-alone or be mounted to the wall. This way, it conserves floor space, and with its slim and attractive design, anyone will be excused if they mistake it for a work of art.

This air purifier utilizes a carbon pre-filter to neutralize unwanted odors. Then, the air flows into the True HEPA filter, which can tackle an array of pollutants, including dust mites, pollen, and smoke up to 0.3 microns in size and help reduce germs, bacteria, and viruses to a lesser degree.
The unit is pretty large, and it would definitely be prominent in any office space. I would also be lying if I said I’m a big fan of its design, but it does its job well, and as long as you have enough floor space for it, you’ll be too busy appreciating the clean air to notice it.
Its air coverage maxes out at around 465 sq. ft, which isn't too high but would still be excellent for medium or small office spaces.
The air purifier has four different settings: allergy, normal, germ, and turbo. Unfortunately, it doesn’t come with an automatic function to adjust the fan’s speed. However, don’t worry about your energy bill. The unit is Energy Star certified, so it’s overall very energy-efficient.
To keep your air purifier up and running, you'll need to replace your filters frequently. Thankfully, the replacement filters are very affordable, so overall, running this unit won't burn a hole in your pocket in the long run.

9. GermGuardian AC4100 3-in-1 Desktop Air Purifier
Sometimes cleaning an entire office space may not be possible. In this case, the next best thing is to use a desktop air purifier to purify the air around your desk. With a price under the $100 mark, I wasn't expecting much from the GermGuardian AC4100 Desktop Air Purifier, but I’m glad to report that it proved me wrong.
This compact 11-inch air purifier can cover an area of around 78 sq. ft. This is obviously nowhere close to all the previous air purifiers, but it’s pretty impressive for a tabletop air purifier nonetheless.
This model comes with a pre-filter that captures larger particles before the air passes into the next filtration stages. It also features an activated carbon filter that neutralizes unwanted odors. Most importantly, the True HEPA filter traps particles 0.3 microns in size.
What I appreciated the most about this air purifier is the fact that it doubles as a sanitizer. In office environments, there are other pressing threats to your health, in addition to allergens, smoke, pollen, and dust. Thankfully, this air purifier boasts a UV-C air filter that sanitizes the air by killing airborne germs, bacteria, and viruses.
My only complaint about this air purifier is the high noise level on the fan’s highest speed. However, it isn’t too distracting, and the other 2 fan speeds aren’t quite as loud.

Why You Should Buy an Air Purifier for Your Office
There are so many airborne threats to your health, especially in public places. Unlike the relatively cleaner home air, the air in office spaces usually carries much more pollutants. This is because offices are usually crowded with people who continuously breathe the same stale air confined to one room.
Even with good air flow inside an office, all the foot traffic will undoubtedly drag in a slew of pollutants, including pollen, dust, dander, and even harmful fumes and gases.
Such pollutants exacerbate allergies and asthma and may cause irritated mucous membranes, which may, in turn, reduce people’s immunity and make them more prone to infections. A good air purifier with powerful filters will be able to trap such minuscule particles to keep the air fresh.
An office air purifier will also help reduce the level of germs and viruses in the air to a lesser degree. And while it won't eliminate all viruses, it'll still help eliminate some of the risks.
Whether you opt for a smaller desktop air purifier or a heavy-duty air purifier with huge room coverage for the entire office, it’ll ensure a reduction in indoor pollutant levels.
Most importantly, inhaling fresh air with a higher level of oxygen can greatly benefit employees' health in the long run. And this will surely increase their productivity as well as the company's profits.
Do Air Purifiers Work in Cubicles?
Yes, they do. The key to effective air purification is placing the air purifier as close to where you're sitting as possible to create a “bubble” of fresh air.
An air purifier placed on the tabletop will clean the air around you much more effectively than if it's placed under your desk or outside your cubicle.
However, keep in mind that most compact tabletop air purifiers will have limited air cleaning capacity and may not have many stages of filtration.
What to Look for When Buying an Office Air Purifier
Finding the best air purifier for your office will be a much easier endeavor if you’re familiar with the most common technical features and jargon associated with air purifiers.
Size and Room Coverage
Air purifiers widely vary when it comes to maximum area coverage. Depending on your budget and what exactly you need it for, you can buy an air purifier that covers anywhere between 100 square feet to 1600 square feet.
Office spaces are usually larger, and their air is usually more polluted than a typical home. Therefore, the more air coverage the air purifier offers, the better. I recommend buying an air purifier with air coverage starting from 700 square feet.
Another option would be to buy a smaller desktop air purifier. Those are usually more economical but offer more modest air coverage.
That said, it will largely depend on how large your office space is, so make sure to check the dimensions of your office space and compare it with the air purifier's specs. It's also advisable to search for an air purifier with 360-degree air intake as those tend to be more efficient.
Moreover, some air purifiers, especially those geared towards larger office spaces, can be rather bulky. Make sure to check if you have enough floor space to place your air purifier. If not, try to look for an air purifier that can be mounted to the wall.
Filter Type
True HEPA Filters
HEPA stands for "high-efficiency particulate air." A true HEPA filter effectively captures tiny airborne particles such as mold spores, dust mites, dander, and cigarette smoke. In fact, it can trap over 99% of pollutants as small as 0.3 microns in size at its highest efficiency.
Most air purifiers on the market boast a True HEPA filter or a HEPA-like filter. That’s because this technology isn’t only proven to be effective in getting rid of airborne contaminants, but also because it doesn’t emit any harmful byproducts that may pose a risk to the users’ health.
PECO Filters
The acronym PECO stands for “photoelectrochemical oxidation.” PECO technology is used proprietarily in the Molekule series of air purifiers.
This technology combines the traditional mechanical filtration method that traps pollutants on filters with a novel ability to destroy said pollutants, including VOCs and even viruses, completely. It even does so at a microscopic scale, and it can tackle particles 1000x smaller than a True HEPA filter can handle.
Activated Carbon Filters
Activated carbon filters are made of carbon that has been modified using heat or chemical treatment in order to increase its pollutants in the air. Unlike other filters, activated carbon filters mainly deal with gaseous contaminants, such as fumes, volatile organic compounds, smoke, and bad odors.
Usually, an air purifier will have an activated carbon filter in addition to a True HEPA filter. Certain air purifier models may also have an activated carbon pre-filter that serves 2 purposes: to trap larger solid particles and eliminate harmful gases.
UV-C Filters
A UV air purifier relies on the unique properties of ultraviolet light to purge the air of contaminants. The air is pulled into the air purifier through a filter. Then, it gets exposed to UV-C radiation, which totally destroys pollutants on a cellular level.
Prolonged exposure to UV-C light is indeed pretty harmful. However, it can be pretty effective in cleaning the air when used in a controlled environment under specific conditions, as is the case with air purifiers.
Smart Controls
An air purifier with a smart air quality sensor can provide real-time feedback and automatically adjust the fan’s speed level according to the current pollution level in the air.
Other air purifiers may boast Wi-Fi and/or Bluetooth connectivity, compatibility with smart assistants, and user-friendly Android or iOS apps. This allows you to control your air purifier even when you’re away from the office.
Performance
You need to keep in mind certain metrics when evaluating the performance of an air purifier against other options.
One such rating is the air purifier's ACH rating, which is short for "air changes per hour." After each air change, all the air in the office will pass through the air purifier and purge all pollutants. Therefore, the more air changes the purifier is capable of performing each hour, the more efficient it'll be at its job and the cleaner your air will be.
You should also pay close attention to the CADR rating of the air purifier, which stands for "clean air delivery rate." In brief, it's the cubic feet per minute (CFM) of air that has been purged of all airborne particles of a specific size. Pick an air purifier with a high CADR rating, as it'll be able to filter more air each minute for the particle's size range.
Energy Consumption
Air purifiers must run 24/7 to be able to do their job efficiently. But since an air purifier can consume anything between 5-200 watts of power, this could mean a hike in your energy bill if you’re not careful. I recommend buying an Energy Star-rated air purifier as it’ll be more energy-efficient.
Noise Level
From near-silent air purifiers and those producing the quietest white noise hum to those that sound like a car motor, air purifiers also vary in the noise they produce.
It’s crucial to consider the noise level produced by an office air purifier. After all, you don’t want to get an office air purifier so loud that it hinders your employee’s productivity.
Many air purifiers feature multiple fan speeds that vary in loudness. However, keep in mind that lower speeds aren’t usually quite as effective in cleaning the air.
Consider opting for a quiet air purifier that produces a noise level below 55 dB, as it will not be too distracting in an office environment. You can also find ultra-quiet air purifiers on the market that operate at only 20 dB or lower.
Aesthetics
This may not be a top priority, but no one will be too pleased with an air purifier that stands like a sore sight in the middle of the office. Some air purifiers are available in various color options to match your office in terms of style and color scheme.
Additionally, some air purifiers sport a sleek, modern look that’d be a perfect match for a fast-paced modern office space. Others may have a more retro look suitable for a more formal office space.
The Bottom Line
Now that you know the best air purifier for office use on the market today, it’s time to make an investment to start reaping all the health benefits that air purifiers can offer.
My top pick is, hands down, the IQAir HealthPro Plus Air Purifier. Unless portability is a priority for you, this medical-grade air purifier offers everything you can ask for and more. It has an impressive setup of filters that can seamlessly eliminate solid particles, harmful chemicals, and unwanted odors.
It also boasts HyperHEPA nano-filtration technology that can filter out much smaller particles that would typically pass through a standard True HEPA filter.
