Top Air Pollution Sources in Office Buildings

According to the U.S. Environmental Protection Agency (EPA), there are five sources for air pollution in office buildings:

  • Furnishings
  • Occupant activities
  • Housekeeping practices
  • Pesticide applications
  • Microbial contamination

The EPA also states that a building’s ventilation system design, operation, and maintenance further contribute to the levels of indoor contaminants found in the workplace. 

Unfortunately, most people don’t have any control over the indoor environment at work, unless they work in a home office. As a result, employees report a large number of health problems that are found to be associated with the air quality inside office buildings.

While not all illnesses are a result of poor air quality inside buildings, the World Health Organization experts have stated that up to 30% of new or remodeled buildings around the world may be the subject of excessive complaints related to indoor air quality.

The most common reason, of course, is the presence of Volatile Organic Compounds or VOCs as we mentioned previously in this air purifier guide.

And the common name for this condition is “Sick Building Syndrome.” The EPA gives a detailed list of the potential root causes of Sick Building Syndrome and the ill effects it has on workers.

As you can see, an air purifier is a great device to have at your workplace because it can eliminate a large number of airborne contaminants that may be making you feel sick or affect your mood and performance. Air purifiers also help with allergies, which is a top concern for some people, in addition to improving overall health.

Another thing you can consider is buying an air quality monitor. These units will detect and measure the various pollutants in the air and report the level of each substance. You can see our page on the best home air quality monitor available to learn more about these devices as well as get the top recommendations for a good unit for every budget.

What To Look For in an Air Purifier for Office Spaces

In a high traffic office full of people are equipment, there are so many different pollutants and contaminants that can be present. To keep the as fresh and clean as possible, you’ll want an air purifier that has at least these two filters:

  • True HEPA Filter
  • Activated Carbon Filter

True HEPA Filter

The True HEPA Filter is crucial in the best office air purifier because it’s the only type of air filter that can trap 99.97% of microscopic particles down to 0.3 microns in size. This includes common office pollutants like dust, allergens, mold spores, bacteria, PM2.5 (from automobile and factory exhaust smoke), etc. Therefore, the best air cleaner for allergies on the market will always have a True HEPA filter.

A True HEPA filter is the only kind that has been certified to capture the ultrafine pollutants that do the most harm to your health and are what many experts consider as the baseline when considering are air purifiers effective or not. Air purifiers that use words like “HEPA”, “HEPA-type”, or “HEPA-like” are less efficient than a True HEPA filter.

Activated Carbon Filter

The Activated Carbon Filter is another must-have feature in the best air purifier for office buildings because it grabs the particles that a True HEPA filter misses. In an office, there are lots of contributing factors to what are called “Volatile Organic Compounds” or “VOCs”.

VOCs are invisible gases and chemical vapors that are emitted by cleaning agents, office equipment, like printers and fax machines, and the building materials that make up the workplace, such as carpeting, paint, drywall, etc. VOCs can “off-gas” from these products for years.

An Activated Carbon filter can trap VOCs that even True HEPA filters can’t by design. Not only does this help with the odors associated with these sources, but capturing VOCs will prevent both the short term negative side effects, which can include ear, nose and throat irritation, headaches, loss of coordination and nausea, and the risks associated with long-term exposure like liver, kidney and central nervous system damage.

How to Find the Right Size Office Air Purifier

The simple way to figure out how big of an air purifier do I need a workspace is to just follow this rule of thumb:

  • Try to meet or exceed the square footage of your office area. Square footage (sq. ft.) is equal to the length x width of the room.

For example, a 40′ x 38′ office space would = 1,520 sq. ft.

And a 10′ x 10′ cubicle would = 100 sq. ft.
