Is the Air in Your Office Damaging Your Brain?

People who live in cities know that it’s not healthy to spend too much time breathing in polluted air near major roads, intersections, and industrial centers. What you may not realize is that the air indoors can be even worse. 

The stagnant air inside enclosed buildings contains the same pollutants as the air outside, but it also traps in all the carbon dioxide people exhale. This is a problem especially in crowded places where people spend extended periods of time, like classrooms and offices. Not only is this air unhealthier than the air outside, but poor air quality at work has also been shown to decrease cognitive function — an office air purifier can help.

Yes, the air in your office is making people stupider

A new study from Harvard found that chronic exposure to fine particulate matter such as carbon dioxide caused slower response times and reduced accuracy on cognitive function tests. The study also mentioned that “the extent to which ambient pollution penetrates and accumulates indoors is influenced by ventilation, infiltration, and filtration.”

People who work in offices often find themselves counting down the hours to their lunch break, sometimes stepping out sooner for a cup of coffee as an excuse to get some fresh air to reenergize themselves for a few hours. Improve the health, cognitive function, and efficiency of your employees by installing an air filtration system in your office and elevating workplace air quality.

1Coway air purifiers have been proven to trap dust, pollen, dander, viruses and bacteria in the air based on KCL (Korea Conformity Laboratories) testing.They have been tested in a 30㎥ size chamber according to the Korea Air Cleaning Association standard (SPS-KACA 002-132:2022 Modified) to measure the 0.01㎛ size of particle removal rate. It was tested on maximum airflow speed in normal room temperature and humidity conditions. The performance may vary in the actual living environment of customers.

3Aerosol test conducted in a Biosafety level 3 laboratory with two Coway air purifier models, Coway Airmega 250 and 400 for removal of SARS-CoV-2 Aerosol by US based MRI Global, a not-for-profit laboratory and partner of US Department of Defense. The test was conducted in a 13.1ft3 chamber. Virus was aerosolized for 15 minutes and the product was turned on high for 2 minutes. Result showed each product effectively removed over 99.98% of the SARS-CoV-2 in 2 minutes. This is a result from a laboratory experiment condition and result may vary in different conditions. This result does not imply it kills SARS-CoV-2 or prevents the transmission of Covid-19. Coway Airmega 250S and 400S are identical to the tested models and has equal performance with an additional mobile connectivity function.

4The concentration of ammonia, acetaldehyde and acetic acid were proven to be removed within 30 minutes by FCG Research Institute, Inc. Human Life Science Lab. It is not a demonstration result in the actual use space. Not all odors and gases may be supported. → Tested with Coway Airmega 150, 160, AP-1512HH, AP-1512HHS, 400, 400S

5The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
