When a cigarette is lit, the tobacco burns at high termperatures. This burning process generates ash, tar and smoke with high number and levels of harmful chemicals. Cigarette smoke is a complex mixture of over 6000 chemical substances, around 100 of which have been to linked smoking-related diseases by public health authorities.

IQOS Heat-not-Burn Technology heats tobacco to a lower temperature, ensuring that combustion does not occur. Because there is no combustion, IQOS does not produce smoke. It generates a tobacco vapor with 95%* less harmful chemicals compared to cigarettes.

"Indoor air quality" (“IAQ”) refers to the air quality inside buildings, generally based on the principle of ensuring the health and comfort of the consumers. Temperature, humidity and contaminants are some of the factors that can affect the indoor air quality. But, human presence and activities such as cooking, cleaning or smoking have been proven to have considerable impact.

To enhance our knowledge and understanding the impact of IQOS on indoor air quality we conducted studies simulating “real-world” conditions in an environmentally controlled room. Our testing methods are validated, and ISO accredited.

Our study shows that, because IQOS does not burn tobacco and it does not generate smoke. it does not negatively impact indoor air quality. This means that the few compounds we nevertheless detected were found at very low concentrations and far below the maximum exposure levels defined in existing air quality guidelines."
