How Air Pollution Impacts Mental Health

When it comes to our bodies, what we put in is what we get out. This applies to the quality of the food we eat, the amount of water we drink and even the air we breathe. While it has long been a well-known fact that our food and water consumption habits affect not only our physical but also our mental health, there is a strong link between the quality of our air and our mental health. 

Studies show links between air pollution and mental illness

Air pollutants, according to the WHO, can cause serious neurocognitive effects ranging from behavioral problems to neurodegenerative disorders. Data from China published in 2018 showed that increases in airborne particulate matter concentration increase the likelihood of having a mental illness by 6.67%. Studies found that air pollutants, specifically particulate matter, induce inflammation and oxidative stress in the brain which can lead to depression. 


A study at Ohio State University exposed mice to high levels of fine particulate air pollution five times a week, eight hours a day, to mimic the exposure a human commuter might receive in a smoggy city. After 10 months, researchers found that the mice exposed to polluted air took longer to learn a maze task and made more mistakes than mice that had not breathed in the pollution. Additionally, the pollutant-exposed mice showed signs of depression, like giving up during swim tests and losing interest in sugar water. What’s more, the mice exposed to polluted air suffered physical changes to the nerve cells in their hippocampus, with fewer spines present on the tips of their neurons. 


These findings are especially relevant to those who live in areas with high levels of air pollution, as the quality of outdoor air inevitably impacts the quality of indoor air. The American Lung Association ranks Bakersfield, Fresno, Visalia, San Francisco and Los Angeles, California as the top 5 most polluted cities in the country by year-round particle pollution. Even in cities with lower levels of air pollution, indoor air quality is still a problem for those who spend a lot of time cooking in poorly ventilated areas or use HVAC systems to heat or cool their homes and workplaces. 

Air purifiers improve indoor air quality 

Air purifiers are extremely important in homes, workplaces and other enclosed indoor spaces because they can filter out harmful pollutants that otherwise could cause adverse effects to physical health, mental health and memory. Use an air purifier in bedrooms, living rooms, offices, gyms and small businesses to lower the impact of harmful air pollutants. 

Coway Airmega has been tested and proven to capture and remove 99.999%1 of fine airborne particles and contaminants with its HyperCaptiveTM Filter technology. A combination of a Green True HEPA™ filter and an activated carbon filter efficiently and effectively clean dust, pollen, dander, viruses and bacteria in addition to smoke, VOCs and PFCs.

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 002-132:2018 Modified) to measure the 0.01㎛ size particle removal rate. It was tested on maximum fan speed in normal room temperature and humidity conditions. The performance may vary in the actual living environment of customers. Tested with 150, 160, AP-1216L, AP-1512HH, AP-1512HHS, 200M, Icon, IconS, 230, 240, 250, 250S, 300, 300S, 400, 400S

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.
