Fears that e-cigarette (e-cig) vapour could compromise indoor air quality have been addressed by a new peer-reviewed study which shows that vapour exhaled from electronic cigarettes has “minimal” impact.
According to Fontem Ventures, owner of e-vapour brand blu, the study shows that exhaled e-vapour product particles are actually liquid droplets that evaporate within seconds, unlike cigarette smoke which can take up to 40 minutes to dissipate.
Exhaled-cig particle counts return “rapidly to background values, reinforcing evidence that vaping has minimal impact on indoor air quality,” it said.
“No accumulation of particles was registered in the room following subjects’ vaping.
“This shows us how fundamentally different exhaled e-vapour particles are compared to those released when smoking conventional cigarettes, the latter of which linger in the air for longer periods of time,” Dr Grant O’Connell, corporate affairs manager at Fontem Ventures, and senior author of the study said.
The research is one of the first detailed studies conducted to investigate the dynamic properties of exhaled e-vapour aerosol particles.
During the study, regular vapers used commercially-available vaping products in a room with no ventilation, while researchers measured particle concentrations in the surrounding air.
“This data adds to the growing body of evidence that vaping indoors is unlikely to pose an air quality issue,” O’Connell added.
The study was a collaboration between Kaunas University of Technology in Lithuania, EMPA (Swiss Federal Laboratories for Materials Science and Technology), ETH Zurich (Swiss Federal Institute of Technology) and Fontem Ventures.
