The broadening effects of wildfire season
In May, NASA satellite images tracked smoke from a wildfire burning near Fort McMurray in Alberta, Canada drifting over Spain. Though it eventually retreated from Western Europe, smoke from the fire, nicknamed The Beast, spread and lingered across much of the Central U.S. and as far southeast as Florida during its two-month-long burn.
Beyond the immediate loss of life and property in the burn zones, the spread of wildfire smoke and ash can have a marked impact on healthy air quality in areas within a radius of hundreds — even thousands — of miles. Though fires are a natural part of the ecosystem, clearing dead brush to make way for new growth, their steady increase over the past few decades have made their impact far more severe.
Climate scientists and meteorologists see prevailing winds carrying smoke across the continent. As plumes rise to 20,000 feet and above, they get caught up in the jetstream — high-altitude currents that circuit air quickly from west to east. In the best-case scenario, pollutants don’t set off air-quality alerts, but instead create colorful sunsets; in the worst-case scenario, air quality can plummet to unhealthy and very unhealthy levels.
Among pollutants present in wildfire smoke, the largest concern is particulate matter. Larger particles from wood-fire smoke present a health risk and reduce visibility; for example, the Erskine Fire in Kern County, California clouded air as far east as Reno and Las Vegas. Smoke also contains potentially dangerous amounts of gasses, the most-prevalent of which is carbon monoxide.
Outside evacuation zones, public-health officials advise residents within range of wildfire smoke to stay indoors and seal up their homes as much as possible. With windows and doors shut, the best course is to run the air conditioning with outdoor venting turned off. Of course, absent the ability to “air out” the house through windows and doors, indoor, smoke-fighting air purifiers can help mitigate any pollutants produced by regular activity around the house, such as cooking and burning candles.

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.

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.
