Resistive external heating
The latest addition to our heated tobacco product (HTP) devices is commercialized as BONDS by IQOS. The Oven Heating System (OHS) uses resistive external heating, with no blade, via the ROUNDHEAT TOBACCO SYSTEMTM, to heat the tobacco across the external surface of the tobacco stick instead of burning it like a cigarette does.
Because the tobacco is heated and not burned, the levels of harmful chemicals in the generated aerosols are significantly reduced compared to cigarette smoke. These devices use specially designed heated tobacco units (HTUs), also known as tobacco sticks, called BLENDS. The HTUs contain specially processed tobacco for heating, two filter sections, and a front plug.
