Does clean air mean clear skin?

As the weather warms up and we head outside, we all know to be extra vigilant about applying sunscreen to protect our skin from harmful, cancer-causing UV rays. But sunlight isn’t the only threat to our skin health during the summer months. Doctors say poor air quality can also do plenty of damage.

A major culprit is fine particulate matter that comes from both outdoor sources (e.g. vehicles, factories, and construction sites) and indoor ones (e.g. fireplaces and stoves). Other dangerous particles are formed when gasses in the atmosphere react with sunlight and water vapor. Ultra-fine particles, specifically, can travel far into our lungs and into the deeper layers of our skin, where they deplete collagen — the protein responsible for averting wrinkles and lines. And one French study found that school children in residential areas with fine particulate matter concentrations higher than 10 micrograms per cubic meter had an increased chance of eczema than children in areas with lower levels.

Nitrogen dioxide, a traffic pollutant, can also damage skin. It and other pollutants contain free radicals that travel into our skin cells. When our bodies are unable to neutralize the interlopers, our skin barriers can fail. One recent Chinese/German study found that an NO2 increase of 10 micrograms per cubic meter was associated with 25 percent more dark spots on the cheeks of women over 50 — giving NO2 a stronger effect on dark spot formation than particulate matter.

At the same time, many harmful substances in our homes can find their way into our bodies through our skin. For instance, off-gassing volatile organic compounds (VOCs) mix with nitrogen oxides and sunlight to create photochemical smog, a chemical cocktail that stresses skin cells. And, if left unmediated by an air purifier or ventilation system, VOCs like benzene, which enters many homes through attached garages, can cause skin irritations.


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.
→ Tested with Airmega Aim, 100, 150, 160, AP-1216L, AP-1512HH, AP-1512HHS, 200M, Icon, IconS, 230, 240, 250, 250 Art, 250S, 300, 300S, 400, 400S, ProX

299.97% of viruses, bacteria, fungi and pollen were verified to be removed from the air for Coway air purifiers which have Green True HEPA™ filter applied based on the Japan Food Research Laboratories(JFRL) testing according to JEM 1467 standard.

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.
