IQOS Devices Compared: Find the Perfect Heat-Not-Burn Device for You in 2025

With the growing shift towards smoke-free alternatives, IQOS has emerged as a front-runner in the heat-not-burn category. As of 2025, the brand offers a variety of models designed for different needs, from the advanced IQOS ILUMA to the classic IQOS 3 DUO. If you're thinking about switching or upgrading, understanding the differences between these devices is crucial. In this guide, we'll compare IQOS devices, outline their features, and help you decide which one suits your lifestyle best.

What is IQOS and How Does it Work?

IQOS is a tobacco heating system developed by Philip Morris International (PMI). Unlike traditional cigarettes that burn tobacco, IQOS heats it, producing a nicotine-containing aerosol without combustion, ash, or smoke. This process significantly reduces the levels of harmful chemicals found in cigarette smoke.

IQOS stands out in the vaping and smoke-free market as a heat-not-burn device, offering a familiar tobacco experience with less odour and residue.

The Evolution of IQOS Devices

IQOS has undergone major innovation since its debut. The brand initially launched with basic models and has since advanced with self-cleaning and induction heating technology. In 2025, users can choose from three major product lines:
