IQOS is a globally recognized heated tobacco product brand developed by Philip Morris International (PMI). It represents PMI’s transition toward a smoke-free future by providing alternatives to traditional cigarettes through tobacco heating technology. Unlike conventional cigarettes, IQOS does not burn tobacco. Instead, it uses controlled heating technology to heat specially designed tobacco sticks, producing a nicotine-containing aerosol without combustion, smoke, or ash. Since its global launch, IQOS has become one of the world's leading heated tobacco systems, with product lines including IQOS ILUMA, IQOS ILUMA PRIME, IQOS ILUMA ONE, and IQOS ORIGINALS. The brand is available in numerous international markets and has become a major player in the smoke-free nicotine product category. IQOS focuses on combining advanced heating technology, premium industrial design, and a cleaner user experience to provide adult smokers with an alternative to conventional cigarettes.
