Deflategate II: air quality and the big game

Gearing up for the big game? If you’re hosting a party, perhaps the last thing on your mind are the contaminants your excited guests are likely to bring with them. But the fact is your visitors may arrive with more than happy vibes and a few cases of beer. They also can be the bearers of various contaminants that cause indoor air pollution.

Forewarned is forearmed, as they say. Here’s a look at just how your friends might unwittingly introduce pollutants into your air and what to do about it.


Whether your guests prefer comfortable sneakers or the latest fashion in booties, their foot garb is sure to carry a largely invisible army of contaminants into your home. Researchers at the University of Arizona recently found an average of 421,000 bacteria with nine different strains on the outside of shoes. That included E. coli, a particularly vicious critter, which can cause everything from diarrhea to meningitis. Another big problem: pesticides. They can remain on shoes long after the wearer traipsed across a recently sprayed lawn. Pro tip: Adopt a no-shoe policy at your party and make it part of the fun with team socks.

Coats and bags

Is your most fervent football fan friend also messy? Or are you unsure how tidy your guests are in their own abodes? Unless they’re clean freaks, it’s likely their home environments are filled with potentially harmful contaminants, from fine glass dust and fiberglass to lead dust, that also collect on their clothing, coats, bags and other items they bring with them.


Do your friends have tchotchkes they haul out from the attic once a year and invariably bring with them? Those foam fingers may add to the festive atmosphere, but they have likely collected a lot of dust and microscopic mold since the last big game.

One way to improve your indoor air when the party arrives is with a smart air purifier with a HEPA filter for your home. It’s sure to be a touchdown.


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.
