The science and vision behind IQOS.
IQOS is the combination of science, technology and vision.
We believe in science. We believe it can change the lifestyle of millions of adult smokers who would otherwise continue to smoke. To this effect, we recruited scientists to work on an important idea: developing less harmful products that adult cigarette smokers can switch to if they don’t quit. At PMI’s global research and development centres in Switzerland and Singapore, we have developed and evaluated IQOS, an innovative electronic device that heats and does not burn tobacco. It produces a tobacco vapour that delivers tobacco taste and nicotine.
Switzerland has been central in the development of the technology behind IQOS. It is in our research and development centre on the shores of Lake Neuchâtel that 430 scientists and engineers have been working tirelessly and in close collaboration with more than 100 Swiss start-ups and SMEs from all over the country to develop and scientifically assess IQOS.
Why heating is better.
Technology – the world revolves around it. Over the years, it has radically changed our lives for the better. The way we work, the way we communicate, the way we travel. By combining science and technology is how we developed a better alternative to continuing smoking which delivers tobacco satisfaction with less smell.
IQOS is changing for the better the way adult smokers, who would otherwise continue to smoke, can enjoy tobacco.
IQOS heats tobacco instead of burning it for a simple reason: the burning of tobacco emits high amounts of harmful chemicals like carbon monoxide. IQOS HeatControl™ Technology prevents tobacco from burning.
When a cigarette is lit, the tobacco burns at temperatures of around 600°C. This burning process generates smoke and ash; when a smoker takes a puff, the temperature rises above 800°C at the burning tip.
Cigarette smoke is a complex mixture of over 6,000 chemical substances, around 100 of which have been linked to smoking-related diseases by public health authorities.
IQOS HeatControl™ Technology heats tobacco to a lower temperature (less than 350°C), ensuring that combustion does not occur. Because there is no combustion, IQOS does not produce smoke. It generates a tobacco vapour that brings you a high-quality tobacco taste experience with 95% less* harmful chemicals compared to cigarettes.
Tested to the highest standards.
IQOS has gone through robust scientific assessments, including, to date, 18 non-clinical and 10 clinical studies involving thousands of participants. The totality of evidence available shows that, while IQOS use is not risk-free, switching completely to IQOS presents less risk to your health than continuing to smoke cigarettes.
Additionally, an increasing number of independent studies and government reports have emerged confirming important elements of our research. To date, more than 85 independent studies have been published.
Cigarettes produce tar, IQOS doesn’t.
Burning a cigarette generates smoke and tar. This is not the case with IQOS. Why?
IQOS heats tobacco instead of burning it. It generates a tobacco vapor that is fundamentally different from cigarette smoke with significantly reduced content of harmful chemicals.*
Cigarettes produce high amounts of carbon monoxide, IQOS doesn't.
Burning a cigarette produces smoke that contains a high amount of carbon monoxide. This is not the case with IQOS. Why? IQOS heats tobacco instead of burning it. It generates tobacco vapor that is fundamentally different from cigarette smoke and contains on average 95% less carbon monoxide (CO).*
Indoor air quality.
Indoor air quality (IAQ) refers to the air quality inside buildings, generally based on the principle of ensuring the health and comfort of the occupants. Temperature, humidity and contaminants are some of the factors that can affect the indoor air quality. However, human presence and activities such as cooking, cleaning and smoking have been proven to have a considerable impact.
To enhance our knowledge and understanding of 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 in your home. 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.
As you probably know, cantons in Switzerland have different regulations with regard to locations where you can smoke or use tobacco products which we recommend you follow.
No. While they are both electronic devices and do not produce smoke like cigarettes, there is one main feature that distinguishes IQOS with HEETS from e-cigarettes: IQOS heats real tobacco, producing tobacco vapor.
Contrary to vaporising an e-liquid, IQOS uses the innovative HEETS tobacco sticks. The tobacco in them is carefully selected and processed to ensure it is evenly heated from the inside, delivering consistent taste and cigarette-like satisfaction. This is why the majority of smokers who switch to IQOS completely quit cigarettes.*

Did you know that we have created a machine that shows the considerable difference between the smoke from a cigarette where the tobacco is burnt compared to the tobacco vapour released by IQOS? Watch the science machine video to see more.
Switching to IQOS.
Our studies show that the satisfaction of those who switched completely to IQOS is comparable to that of those who continued to smoke cigarettes.* Discover more about our scientific assessment journey.
