Independent data An independent study simulating secondhand exposure to submicron particles (SMP) showed four times lower emissions from IQOS in comparison to cigarettes, but a return to background levels immediately after use termination, implying that IQOS use is not a persistent indoor air pollutant.85 In contrast, another study showed that although SMP emissions from IQOS are one order of magnitude lower than cigarette smoke, levels were still higher than baseline values 1 hour after IQOS use.86 Two studies showed that IQOS emitted the least PNC of ultrafine, fine and coarse particles in an indoor environment compared with an e-cigarette and a combustible cigarette.87 88 The conclusion that IQOS is the least indoor air pollutant was confirmed by another study that nevertheless estimated concerning acrolein levels.46 Moreover, a study showed significantly lower secondhand VOC and PM emissions from IQOS compared with combustible cigarettes and e-cigarettes.89 A study indicated that IQOS has significantly less intense and persistent impact on indoor air quality compared with combustible cigarettes, and significantly lower than a competing HTP from British American Tobacco (ie, Glo) and a leading e-cigarette (JUUL).90 This study found some differences in IQOS secondhand emissions depending on flavour
