IQOS is a range of tobacco heating devices designed for use with compatible tobacco sticks and, in selected models, tobacco-free nicotine sticks. This guide covers IQOS ILUMA and IQOS ILUMA i models, differences between devices, compatible sticks, key functions, charging, maintenance and safety precautions.
What is IQOS?
IQOS is an electronic heating system that heats specially designed tobacco sticks without burning the tobacco in the same way as a conventional cigarette.
Earlier IQOS devices use a heating blade, while newer IQOS ILUMA models use the SMARTCORE INDUCTION SYSTEM, which heats a metal element inside a compatible stick.
IQOS devices do not use e-liquid in the same way as conventional electronic cigarettes. Instead, they operate with specially designed solid sticks containing tobacco or a tobacco-free nicotine substrate.
IQOS products and compatible sticks are not risk-free. Tobacco sticks and nicotine sticks contain nicotine, which is addictive. These products are intended only for adults who already use tobacco or nicotine products.
How IQOS ILUMA technology works
IQOS ILUMA devices use the SMARTCORE INDUCTION SYSTEM to heat compatible sticks without a heating blade.
Each compatible stick contains an internal metal heating element. When inserted into an IQOS ILUMA device, this element is heated through electromagnetic induction.
The absence of a heating blade distinguishes IQOS ILUMA from older IQOS generations and eliminates the need to clean tobacco residue from a heating blade.
IQOS ILUMA devices are designed for compatible SMARTCORE STICKS, including TEREA, DELIA and LEVIA. They cannot be used with HEETS sticks designed for earlier blade-based devices.
IQOS ILUMA models
The IQOS ILUMA range includes several models with different designs, battery configurations and features.
Earlier-generation IQOS ILUMA devices include:
• IQOS ILUMA
• IQOS ILUMA PRIME
• IQOS ILUMA ONE
The newer IQOS ILUMA i generation includes:
All six models use bladeless induction heating and are designed for compatible IQOS ILUMA sticks.
Differences between models primarily involve device construction, battery configuration, charging arrangements and additional electronic functions.
IQOS ILUMA i
IQOS ILUMA i is a two-piece device consisting of a Holder and a separate Pocket Charger.
The Holder contains the induction-heating system, while the Pocket Charger provides power for recharging the Holder between uses.
IQOS ILUMA i includes a Touch Screen that displays preheating progress, remaining session time and available uses.
Additional functions include Pause Mode, FlexPuff and FlexBattery, allowing certain aspects of operation to be adjusted according to device settings.
In Performance Mode, the Holder may support up to three consecutive uses without activating Pause Mode, subject to battery condition and device settings.
IQOS ILUMA i is compatible with TEREA, DELIA and LEVIA sticks.
IQOS, ILUMA et PRIME
IQOS ILUMA i PRIME is a two-piece model consisting of a Holder and Pocket Charger, with a premium exterior design and finish.
It uses the same SMARTCORE INDUCTION SYSTEM as the other IQOS ILUMA i models.
IQOS ILUMA i PRIME includes a Touch Screen, Pause Mode, FlexPuff and FlexBattery functions.
The Touch Screen provides information about preheating progress, remaining session time and available uses.
The Holder may support up to three consecutive uses in Performance Mode without activating Pause Mode, depending on battery condition and usage.
The main differences between IQOS ILUMA i PRIME and IQOS ILUMA i concern exterior design, materials and finish rather than stick compatibility.
IQOS ILUMA i PRIME is compatible with TEREA, DELIA and LEVIA sticks.
IQOS, ILUMA et i ONE
IQOS ILUMA i ONE is a compact all-in-one device that combines the heating system and rechargeable battery in a single body.
Unlike IQOS ILUMA i and IQOS ILUMA i PRIME, it does not require a separate Holder and Pocket Charger.
The device uses bladeless induction heating and supports automatic activation and deactivation when a compatible stick is inserted or removed.
IQOS ILUMA i ONE supports FlexPuff but does not include the same Touch Screen and Pause Mode functions as the two-piece models.
The device can provide up to 20 sessions on a full battery charge, depending on usage and battery condition.
Charging is performed through a USB Type-C connection.
IQOS ILUMA i ONE is compatible with TEREA, DELIA and LEVIA sticks.
Differences between IQOS ILUMA i models
The three IQOS ILUMA i models share the same basic induction-heating technology but differ in construction and available features.
• IQOS ILUMA i: Two-piece system with Holder and Pocket Charger, Touch Screen, Pause Mode, FlexPuff and FlexBattery.
• IQOS ILUMA i PRIME: Premium two-piece system with the same core functions and a different exterior design and finish.
• IQOS ILUMA i ONE: Compact all-in-one system with integrated rechargeable battery, AutoStart/AutoStop and FlexPuff, without a separate Pocket Charger.
All three models are designed for compatible SMARTCORE STICKS, and the choice of device does not change the basic compatibility with TEREA, DELIA and LEVIA.
Battery performance, available functions and session limits may vary depending on the device model, settings, firmware and battery condition.
What sticks are compatible with IQOS ILUMA?
IQOS ILUMA and IQOS ILUMA i devices are designed for compatible SMARTCORE STICKS containing an internal metal heating element.
Three principal stick ranges are available:
• TEREA: Tobacco sticks containing an internal metal heating element. Available in different tobacco, menthol and aromatic flavour profiles.
• DELIA: Tobacco sticks containing an internal metal heating element, with a focus on classic tobacco flavour profiles.
• LEVIA: Tobacco-free nicotine sticks containing a plant-based substrate with added nicotine and flavourings.
All three ranges are designed for compatible IQOS ILUMA devices and use the SMARTCORE INDUCTION SYSTEM.
TEREA and DELIA contain tobacco and nicotine. LEVIA does not contain tobacco but still contains nicotine.
None of these products is nicotine-free or risk-free.
Devices that are not compatible with TEREA, DELIA or LEVIA
TEREA, DELIA and LEVIA must not be used with earlier blade-based IQOS devices, including:
• IQOS 3 DUO
• IQOS ORIGINALS DUO
• IQOS ORIGINALS ONE
• IQOS 2.4 PLUS
These devices use a different heating system and are designed for compatible earlier-generation tobacco sticks.
The internal metal heating element in TEREA, DELIA and LEVIA makes these sticks unsuitable for devices with a heating blade.
Using incompatible sticks may damage the device. Always check the full model name and manufacturer instructions before use.
IQOS ILUMA vs older IQOS devices
The main difference between IQOS ILUMA and earlier IQOS generations is the heating technology.
• IQOS ILUMA and IQOS ILUMA i: Use bladeless induction heating with compatible TEREA, DELIA and LEVIA sticks containing an internal metal heating element.
• Earlier blade-based IQOS devices: Use a heating blade inside the device and are designed for compatible HEETS tobacco sticks.
These heating systems are not interchangeable.
Do not insert HEETS into an IQOS ILUMA device or TEREA, DELIA or LEVIA into an earlier blade-based IQOS device.
IQOS ILUMA and IQOS ILUMA i also differ in available electronic features. Newer ILUMA i models introduce functions such as Touch Screen, Pause Mode and FlexBattery on selected devices.
