Pure air’s positive impact on athletic performance

During exercise, especially aerobic exercise, more air tends to enter our lungs through our mouths as we breathe deeply. When this occurs, outside air bypasses our nose and nasal passageway, a biological adaptation designed to trap airborne contaminants before the air we breathe reaches our lungs. When we breathe through our mouth, these contaminants instead are sent straight through to our respiratory system. This means air containing pollutants or other particulate matter is more likely to be entering our bodies unfiltered in places like gyms.

While outdoor air quality is impossible to control, air purifiers like Coway Airmega make it possible to breathe fresh, clean air free from pollution and particulate matter indoors. Breathing purified air is healthy for your brain and body, as it helps you to think, focus and concentrate better as well as function more efficiently as a whole by delivering oxygen efficiently through your blood.

Researchers in Portugal conducted a study in which they placed air quality monitors in 11 gyms for several hours. What they found was surprising. In the gyms monitored, they discovered concentrations of dust, formaldehyde and carbon dioxide in levels above most accepted standards for indoor air quality. Even more disturbing were results during aerobic classes, where many people work out in small, cramped studios.

During these classes, contaminant levels were especially high, with participants breathing out carbon dioxide and stirring airborne dust and other particles with each movement. Although carbon dioxide is not toxic to people, it has been linked to fatigue and mental fogginess, which are not conducive to athletic training. Additionally, unfiltered air in crowded spaces where many people are breathing heavily can increase the risk of contracting airborne illnesses. 

Airmega uses multiple layers of filtration, including a Green True HEPA™ filter, that can capture and remove over 99.98%³ of the SARS-CoV-2 virus and more than 99.999%¹ of all airborne contaminants down to 0.01 microns, exceeding the EPA’s recommendation for air purifiers.

¹Coway air purifiers has 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 of 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.
