How Heated Tobacco Devices Work?

Discover how heated tobacco devices work and the benefits of switching to IQOS, the heat-not-burn alternative to continued smoking.

Heated tobacco devices are also called heat-not-burn devices because of the fact that they heat tobacco instead of burning it. Essentially, the two terms - heated tobacco and heat-not-burn - are interchangeable.

At the heart of our IQOS, heated tobacco devices are sophisticated electronics that heat specially designed tobacco sticks called tobacco sticks. Since IQOS heat-not-burn devices are battery-powered, they need to be charged regularly, just like you would charge a smartphone. Once the IQOS heated tobacco device is ready, a tobacco stick is inserted into the device. By pushing a button to begin the heating process, an IQOS legal age user can then inhale the vapor that is released. Once the experience is over, the used tobacco stick can be removed from the device and disposed of in a bin.

Since the tobacco is heated and not burned, IQOS emits 95% less harmful chemicals compared to cigarettes.* Important information: It does not necessarily equal a 95% reduction in risk. IQOS is not risk-free.

* ”95% less” represents the average reductions in levels of a range of harmful chemicals (excluding nicotine) compared to the smoke of a reference cigarette (3R4F). See Important Information.


The best of IQOS technology

From thought to reality, each element of IQOS is carefully crafted.

IQOS HeatControl™ Technology is the heart of the product. Designed in Switzerland, it is responsible for heating tobacco, without burning it, to precise temperatures up to 350⁰C.

The ceramic blade inside IQOS, which has gold and platinum tracks, heats the tobacco stick inside. So IQOS adult users get the experience of the real tobacco in the tobacco stick, with no smoke, no ash and with less smell than cigarettes.
