What Is IQOS? Everything You Need to Know
Jessica Tyson
25/03/2025 • 5 min readAs adult smokers explore smoke-free alternatives to conventional cigarettes, a growing number are asking: What is IQOS? Developed by Philip Morris International (PMI), IQOS represents a new generation of tobacco products that heat tobacco rather than burn it. This key difference in technology delivers a familiar experience while producing no smoke and less odour than traditional cigarettes.
But how does IQOS actually work, and how does it compare with other alternatives like vaping? Let’s break it down.
What Is IQOS?
IQOS is a heated tobacco system that uses real tobacco, specially processed into sticks, which are heated using an electronic device. Unlike smoking, there is no combustion — the tobacco is heated just enough to release a flavourful nicotine-containing aerosol, without creating smoke. By avoiding the high temperatures of burning (which can reach over 600°C in cigarettes), IQOS aims to deliver a similar ritual and taste, but with reduced levels of the harmful chemicals typically produced by combustion.

So, is IQOS an e-cigarette? Although IQOS and e-cigarettes are often grouped together under the umbrella of "smoke-free alternatives," they are fundamentally different.
- E-cigarettes heat a liquid (usually containing nicotine, flavours, and other chemicals) using a battery-powered coil to create a vapour.
- IQOS, on the other hand, heats real tobacco using a specially designed blade (or induction system in newer models) — not a liquid.
Ultimately, the answer is no — IQOS is not an e-cigarette. It offers a tobacco-based experience for adult smokers seeking an alternative that retains more of the flavour and ritual of smoking.
IQOS vs. E-Cigarettes: Key Differences
When comparing IQOS to e-cigarettes, several factors stand out:
Technology
- IQOS: Uses a heating blade or induction system that heats tobacco sticks.
- E-cigarettes: Vaporise e-liquids with a heated coil.
User Experience
- IQOS: Uses real tobacco to closely mimic the taste and ritual of a cigarette.
- E-cigarettes: Often flavoured, offering a different sensory experience without tobacco.
Residue & Maintenance
- IQOS: Requires occasional cleaning to remove tobacco residue (older models).
- E-cigarettes: Need frequent refilling and replacement of coils or pods.
What Is the Difference Between IQOS and Vape?
This is a common question, and, although vaping and IQOS are both non-combustion alternatives to smoking, the core distinction lies in what they heat, making IQOS a unique tobacco product.
Composition
Vapes: Use e-liquids which may contain nicotine, propylene glycol, flavourings, and other compounds. IQOS: Uses compressed tobacco sticks, providing a direct tobacco experience.
Maintenance
Vapes: Involve more upkeep with refilling, coil changes, and battery maintenance. IQOS: Especially with ILUMA, IQOS offers a more streamlined experience — no liquids, no coil changes, and minimal cleaning required.
What Is IQOS ILUMA?
IQOS ILUMA One is the most advanced generation of IQOS devices, featuring the brand's Smartcore Induction System™ technology. This bladeless heating system warms the tobacco from within using induction, eliminating some of the common issues seen in older devices — such as the need for cleaning or risk of blade breakage.
This innovation not only enhances performance but also makes the overall user experience cleaner and more convenient. Tobacco companies like Philip Morris continue to invest in such advancements to offer better alternatives to traditional smoking.
What Is TEREA IQOS?
TEREA are tobacco sticks designed exclusively for use with IQOS ILUMA One. Each TEREA stick includes a metal heating element that works seamlessly with ILUMA’s induction technology. These sticks are fully sealed, meaning there’s no loose tobacco and no residue left in the device — a significant upgrade in hygiene and usability compared to traditional tobacco cigarettes.
What Is IQOS ORIGINALS?
IQOS ORIGINALS refers to earlier models in the IQOS line, such as:
- IQOS 2.4
- IQOS 3
- IQOS 3 DUO
These devices use a heating blade system and require manual cleaning to maintain optimal performance. Although they provide the authentic tobacco experience that IQOS is known for, they lack the convenience and innovation seen in ILUMA, and may still produce some level of tobacco smoke.
These models remain available in some markets for users who prefer a more familiar format or are exploring IQOS for the first time.
Is IQOS Right for You?
IQOS offers a distinct alternative for adult smokers seeking a tobacco-based, smoke-free experience. Although it is not a cessation tool, it may be a step towards reducing smoking habits for those looking to quit smoking. Unlike vaping, IQOS delivers real tobacco taste through advanced heating technology.
For those ready to start their smoke-free journey, the IQOS ILUMA is a user-friendly, refined alternative to cigarettes that’s simple and easy for ex-smokers to get to grips with.
