However, applying a high voltage to a low-resistance heating coil can easily heat e-liquids to temperatures in excess of 300 °C; temperatures sufficient to pyrolyze e-liquid components." [59]
Most devices have a manual push-button switch to turn them on or off. [6] E-cigarettes do not turn on by trying to "light" the device with a flame. [11] The e-liquid reaches a temperature of roughly 100-250 °C within a chamber to create an aerosolized vapor. [7] Variable voltage devices can raise the temperature. [30]

VHP is produced from a solution of liquid H 2 O 2 and water, by generators specifically designed for the purpose. These generators initially dehumidify the ambient air, then produce VHP by passing aqueous hydrogen peroxide over a vaporizer, and circulate the vapor at a programmed concentration in the air, typically from 140 ppm to 1400 ppm, depending on the infectious agent to be cleared.
