Key points at a glance
- Heets are the sticks for the older IQOS generation (with a heating blade), Terea for the new Iluma devices.
- Terea uses SMARTCORE Induction – a metal core in the stick heats from the inside, completely without a blade.
- Not compatible: Terea only fits Iluma, Heets only fits older IQOS models.
- Terea has the advantage that the device no longer needs to be cleaned.
- Both are nicotine-containing tobacco sticks for ages 18 and up.
Terea or Heets – if you're starting with an IQOS device or switching from an old model to the Iluma series, you can't avoid this question. The short answer: Both sticks are for different device generations; they are not interchangeable. We'll show you what the differences are, which sticks fit which device, and what you need to consider when switching.
Heets and Terea – two generations, two sticks
There's more to the name than just a different logo: Heets and Terea are technically two different products for two different device generations.
- Heets: The classic tobacco sticks for older IQOS models like the IQOS Originals or the IQOS 3 Duo. These devices work with a heating blade that is inserted into the stick.
- Terea: The new generation of tobacco sticks exclusively for IQOS Iluma devices. Here, the heating element is located directly in the stick – heated contactlessly via inductive heating.
Important to know: Heets do not fit into Iluma devices. And Terea do not fit into old IQOS models. Those who switch to Iluma leave their Heets stock behind and switch to Terea.
SMARTCORE Induction Technology explained briefly
The most important technical difference lies in the heating system. With old IQOS devices, a metal plate heats the tobacco from the inside. This works well but leaves tobacco residue in the holder – regular cleaning is necessary.
Iluma devices use SMARTCORE Induction: The Terea stick itself contains a tiny metal plate that is heated by the device via induction without direct contact. This has three advantages:
- No heating blade that can get dirty or break.
- No cleaning of the holder necessary – Terea sticks are closed at the bottom.
- Consistent heating throughout the session – this improves the taste.
Taste and tobacco profile – what are the differences?
Both stick generations use real tobacco, but Philip Morris has optimized the blend for Terea. The sticks burn longer, the taste is more intense, and, most importantly, more stable from the first to the last puff. With Heets, the taste often diminished towards the end of the session.
The range of flavors for Terea is also significantly larger and more diverse. In the Smokez IQOS assortment, you'll find classic tobacco variants like Terea Amber, Bronze, or Sienna, as well as fresher varieties like Turquoise and Yellow Green. Those who want to go without tobacco can opt for Levia – these are plant-based nicotine sticks instead of tobacco.
Which sticks for which device – the quick overview
- Heets: for IQOS 3, IQOS 3 Duo, IQOS Originals (Heating Blade devices)
- Terea, Delia, Levia: only for IQOS Iluma, Iluma Prime and Iluma One
If you still use an old IQOS model: It will continue to work – but Philip Morris is gradually discontinuing the production and distribution of Heets. Switching to Iluma is the more sensible long-term choice.
Cleaning and maintenance – Terea clearly scores here
Anyone who has worked with an IQOS 3 Duo knows it: After 20 Heets, the holder must be cleaned, otherwise the taste suffers, and the heating blade can break. With Iluma and Terea, this is completely eliminated. You take the stick out, throw it away, insert the next one. Done.
This small improvement makes a huge difference in everyday life – especially when you're on the go or use the device frequently.

FAQ – Terea vs Heets
Can I insert Terea into my old IQOS 3 Duo?
No. Terea are designed only for Iluma devices and contain a metal plate that can damage a heating blade. It also doesn't work the other way around – Heets would neither be heated nor recognized in an Iluma device.
Are Terea and Heets equally expensive?
The prices per pack are similar depending on the variety – in the range of 6 to 7 euros per 20 sticks. However, since Terea draw more consistently and the taste remains stable, the price per session often feels better.
Which Terea varieties are suitable for Heets switchers?
Those who loved Heets Bronze will feel at home with Terea Bronze or Terea Amber. Heets Yellow fans should opt for Terea Yellow or Terea Sienna. Fresh, menthol Heets lovers will find their new favorite stick with Terea Turquoise or Terea Yellow Green.
Is the switch to Iluma worth it at all?
Yes – definitely in the long run. Iluma devices require less maintenance, the taste is more consistent, and the selection of sticks is continuously expanding. Heets are gradually being removed from the market.
