Research Looking at the Effect of E-Cig Vapour on Indoor Air

The authors of this study looked at the level of two types of particulate matter (PM) air pollution; lower measurement aerodynamic diameter (≤2.5 μm), PM2.5 and ultrafine particles (UFPs) at 0.5 meters (m) and 1 m away from an e-cigarette user. The study investigated whether these indoor concentrations varied according to the type of device used, testing three
