Researchers: E-cigs still create secondhand smoke
The Research
The dangers of secondhand smoke have been studied for decades, but we know far less about the effects of electronic cigarettes, which vaporize a fluid mixture instead of burning tobacco. So researchers from Virginia Commonwealth University decided to test the vapor; the team measured fine particulate matter concentrations before, during, and after a two-day e-cigarette event attended by 56-89 active smokers.
The Results
During the event, median fine particulate matter reached nearly 41,000 times its smoke-free level, with concentrations ranging from 312 micrograms per cubic meter to 819 micrograms per cubic meter (to level set: 56 smokers in an airport bar produce about 553 micrograms per cubic meter, on average). In fact, peak concentrations at the e-cigarette event topped those recorded at hookah bars in Oregon in 2012.
The Takeaway
E-cigarettes are often perceived as a healthier alternative to tobacco cigarettes, but we now know that their vapors do affect healthy air quality and could therefore be just as damaging to health. Independent research has shown that fine particulate matter, like that in secondhand smoke, can contribute to asthma, respiratory and cardiovascular diseases, and lung cancer.

Disclaimers
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. 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.
