📌 Main innovation: controlled heating of real tobacco instead of burning it.
How IQOS Creates Aerosol Without Fire
Cigarette combustion temperature: >700°C
IQOS heating temperature: ~300°C
This prevents:
• smoke formation
• ash & tar generation from open burning
• fire hazard
📌 By removing combustion, exposure to many harmful chemicals is reduced.
Two Heating Generations: Blade vs Induction
IQOS has transitioned through two technological eras:
Technology Used in Works With Heating Method
Heating Blade IQOS 2.4+, IQOS 3 DUO HEETS Metal blade inserted into tobacco
Smartcore Induction IQOS ILUMA series TEREA Magnetic induction heats core from inside

📌 Both aim to deliver tobacco satisfaction without smoke.
The Heating Blade System — Classic IQOS Engineering
Blade advantages:
• strong aerosol “kick”
• tobacco‑forward sensation
Blade challenges:
• requires regular cleaning
• blade can break if mishandled
📌 Ideal for adult smokers who prefer more cigarette‑like intensity.
Induction Heating — IQOS ILUMA Innovation
Smartcore Induction:
• heats tobacco from inside the stick
• removes blade & insertion friction
• reduces residue buildup
📌 Cleaner experience + more consistent aerosol.
Why Temperature Control Matters for Toxicology
Cigarette smoke contains thousands of harmful chemicals due to burning.
IQOS prevents pyrolysis reactions that create:
❌ carbon monoxide
❌ tar
❌ combustion particulates
📌 Heating reduces toxicant formation — not elimination of risk.
How IQOS Aerosol Forms Compared to E‑Cigs
Key difference:
Feature IQOS Vaping
Source material Real tobacco Nicotine e‑liquid
Aerosol base Glycerin + heated tobacco Vaporized liquid
Sensation Cigarette‑like Softer, less tobacco impact
📌 IQOS is designed for smokers who want tobacco experience without smoke.
Structural Design of IQOS Heating Chamber
System includes:
• heat control sensors
• airflow channels
• smart shutdown to prevent overheating
This ensures:
✔️ safety
✔️ consistent delivery
✔️ no ignition
Heated tobacco internal design
📌 The device actively prevents temperatures from reaching combustion levels.
Harm‑Reduction Perspective
IQOS can reduce exposure to harmful chemicals compared to smoking only if:
• cigarettes are completely replaced
• dual use is avoided
Scientific switching effectiveness
📌 The technology is designed for existing adult smokers — not youth or non‑smokers.
Final Summary — IQOS Heating = Fire‑Free Tobacco Innovation
✔️ Heats tobacco instead of burning
✔️ Delivers nicotine aerosol without smoke
✔️ Reduces exposure to combustion toxicants
✔️ Comes in blade and induction versions
✔️ Works only with engineered tobacco sticks
✔️ Supports switching for adult smokers only
📌 By removing fire and smoke, IQOS reshapes tobacco use into a controlled, reduced‑exposure format.
