If you use an IQOS ILUMA device, you may have come across three different types of SMARTCORE sticks: TEREA, DELIA and LEVIA.
They may look similar and are designed for the same family of devices, but they are not the same product. The most important difference is simple:
TEREA and DELIA contain tobacco, while LEVIA contains no tobacco.
All three are designed for the IQOS ILUMA family and use SMARTCORE technology. In this guide, we explain their differences, compatibility and the type of experience each range offers.
TEREA, DELIA and LEVIA: quick comparison
| Stick type | Contains tobacco | Contains nicotine | Compatible with IQOS ILUMA | Compatible with older blade-based IQOS devices |
|---|---|---|---|---|
| TEREA | Yes | Yes | Yes | No |
| DELIA | Yes | Yes | Yes | No |
| LEVIA | No | Yes | Yes | No |
Which devices are TEREA, DELIA and LEVIA compatible with?
TEREA, DELIA and LEVIA are designed for devices from the IQOS ILUMA family.
This includes models such as:
- IQOS ILUMA
- IQOS ILUMA ONE
- IQOS ILUMA PRIME
- IQOS ILUMA i
- IQOS ILUMA i ONE
- IQOS ILUMA i PRIME
These sticks are not designed for older IQOS devices that use a heating blade.
The reason is that IQOS ILUMA uses a different heating technology. SMARTCORE sticks contain a built-in metal element that interacts with the induction system inside the device.
Older IQOS generations use a physical heating blade instead, so the two systems are not interchangeable.
What are TEREA sticks?
TEREA are heated tobacco sticks developed specifically for IQOS ILUMA devices.
They contain a specially prepared tobacco blend and an integrated heating element inside the stick. Instead of inserting a heating blade into the tobacco, an IQOS ILUMA device heats the stick from within using induction technology.
TEREA is generally the most varied of the three ranges. Depending on availability, the range may include:
- classic tobacco profiles;
- menthol and cooling profiles;
- aromatic blends;
- fruit-inspired flavour notes;
- capsule variants.
This makes TEREA suitable for users looking for a broad selection of flavour profiles while continuing to use a tobacco-based stick.
TEREA in brief
- Contains tobacco: Yes
- Contains nicotine: Yes
- Designed for IQOS ILUMA: Yes
- Designed for older blade-based IQOS devices: No
What are DELIA sticks?
DELIA are also heated tobacco sticks designed for the IQOS ILUMA family.
Like TEREA, DELIA contains tobacco and nicotine and uses the SMARTCORE format.
The main difference between TEREA and DELIA is therefore not compatibility. Both are intended for the same type of device.
The difference is mainly in the product range and flavour positioning.
TEREA usually offers a wider variety of flavour directions, while DELIA tends to focus more strongly on tobacco-led profiles.
Exact flavours can vary depending on the market and current product availability.
DELIA in brief
- Contains tobacco: Yes
- Contains nicotine: Yes
- Designed for IQOS ILUMA: Yes
- Designed for older blade-based IQOS devices: No
What are LEVIA sticks?
LEVIA are different from both TEREA and DELIA because LEVIA does not contain tobacco.
Instead of a tobacco plug, LEVIA uses a plant-derived material designed to produce a flavoured nicotine-containing aerosol when heated in a compatible IQOS ILUMA device.
This is an important distinction:
Zero tobacco does not mean zero nicotine.
LEVIA still contains nicotine and is intended for adult nicotine users.
Its flavour range is typically focused more strongly on fresh, cooling, fruity and aromatic profiles rather than traditional tobacco character.
LEVIA in brief
- Contains tobacco: No
- Contains nicotine: Yes
- Designed for IQOS ILUMA: Yes
- Designed for older blade-based IQOS devices: No
TEREA vs DELIA: what is the difference?
TEREA and DELIA have a lot in common.
Both:
- contain tobacco;
- contain nicotine;
- use SMARTCORE technology;
- are designed for IQOS ILUMA devices;
- are not intended for older blade-based IQOS devices.
The main difference is the selection of blends and flavour profiles.
TEREA generally provides a broader range of options, including tobacco, cooling, aromatic and flavour-focused variants.
DELIA is more closely associated with tobacco-focused profiles and provides an alternative range for users who prefer that style.
From a device compatibility point of view, there is no need to choose between TEREA and DELIA based on the IQOS ILUMA model you own.
TEREA vs LEVIA: what is the main difference?
The biggest difference between TEREA and LEVIA is what is inside the stick.
TEREA contains tobacco.
LEVIA does not contain tobacco.
LEVIA uses a plant-derived material instead, although it still contains nicotine.
Both ranges are designed for IQOS ILUMA devices, so the choice is primarily about whether you prefer a tobacco-based stick or a zero-tobacco nicotine stick.
DELIA vs LEVIA
The same basic difference applies when comparing DELIA and LEVIA.
DELIA is a heated tobacco product.
LEVIA is a zero-tobacco nicotine product.
Both use the SMARTCORE format and are designed for the IQOS ILUMA family.
Can you use TEREA, DELIA or LEVIA in older IQOS devices?
No.
TEREA, DELIA and LEVIA are designed for the induction-based heating system used by IQOS ILUMA devices.
Older IQOS models use a different system with a heating blade. SMARTCORE sticks should therefore not be used with those previous-generation devices.
The reverse also applies: sticks developed for older blade-based IQOS devices are not designed for IQOS ILUMA.
Which sticks should you choose for IQOS ILUMA?
From a compatibility perspective, all three ranges are designed for IQOS ILUMA.
The main difference is the type of product and flavour experience:
- TEREA — heated tobacco sticks with the broadest variety of flavour profiles.
- DELIA — heated tobacco sticks with a stronger focus on tobacco-led profiles.
- LEVIA — zero-tobacco nicotine sticks with more flavour-focused profiles.
The easiest way to remember the difference is:
TEREA = tobacco
DELIA = tobacco
LEVIA = zero tobacco
