Media coverage on IQOS - HEETS Filters

To IQOS consumers in Switzerland

I am writing to you to clarify some facts that have received media attention in the last few days in connection with IQOS and more specifically with the filter in HEETS tobacco sticks. This information could be misinterpreted.

As an IQOS user, you will have noticed that your HEETS tobacco sticks have a filter designed to reduce the temperature of the tobacco vapor generated by IQOS. This filter is made of a thin polymer film.

Recently, a laboratory analyzed the HEETS filter by putting it on its own in “an oven” at different temperatures. Under these extreme test conditions, a harmful constituent was detected. However, as you will have gathered, this experience in no way reflects the normal way you use your IQOS.

We have analyzed in the finest detail the tobacco vapor that is generated by IQOS and which you inhale, and we can confirm that this harmful constituent is not found there.

I would like to take this opportunity to remind you that our studies scientifically show that the tobacco vapor produced by IQOS is 90% less toxic than the smoke from a cigarette. Moreover, there are almost 30 independent studies that confirm key elements of our research. And although IQOS is not risk free, just like all tobacco- or nicotine-based products, it is a better alternative to cigarettes.

Thank you for trusting us and please visit to learn more about the science of IQOS.
