IQOS has become a revolutionary alternative to traditional smoking for adult smokers who want a less harmful, smoke-free experience. With each generation, the technology has improved taste, reliability and usability. The launch of the IQOS ILUMA i is another big step in that journey.
But what is different about the ILUMA i compared to its predecessors? Is it worth upgrading if you already have an older IQOS device?
In this breakdown, we’ll cover all the key differences between the IQOS ILUMA i and previous IQOS models, like the IQOS 3 DUO and earlier. We’ll also look at how these changes impact daily use and what benefits they bring to users.
1. Heating Technology: Smartcore Induction Systemâ„¢ vs. Heating Blade
One of the main changes in the ILUMA i is the switch from a heating blade to the Smartcore Induction Systemâ„¢.
Previous IQOS devices used a ceramic blade to heat the tobacco stick from the inside. While this worked well, it had some downsides. The blade was fragile and could break if too much pressure was applied during stick insertion. Also, over time, tobacco residue would build up around the blade and you would need to clean it to maintain performance and hygiene.
The IQOS ILUMA i uses induction heating. This bladeless system heats the tobacco from the inside using magnetic induction, targeting the metal layer built into TEREA sticks, which are designed specifically for the ILUMA series. Because the tobacco is never in direct contact with a blade, you avoid ash, residue and the mess that comes with traditional heated tobacco devices.
Key Benefits of the New Heating System:
- No blade means no breakage.
- No cleaning required.
- More even heating and better flavor consistency.
- Smoother draw.
2. No Cleaning Required: A Real Convenience Upgrade
Older IQOS devices required cleaning. This was necessary to remove residue from the heating blade, ensure proper airflow and preserve flavor. For some users, especially new ones, this was a chore.
The ILUMA i eliminates that completely. The bladeless system doesn’t accumulate residue, so there’s no need to clean the device between uses. This saves time and reduces the risk of damage during cleaning. Daily users will love this. Just insert, use and you’re done.
3. Taste and Flavor Experience
With precise heating of the Smartcore Induction Systemâ„¢, ILUMA i offers more refined and consistent flavor. Each stick is heated evenly from the core, for a smooth experience from start to finish.
In older models, taste could vary depending on how clean the blade was, how well the stick was inserted or if the blade was damaged. The ILUMA series eliminates all of that.
Also, the TEREA sticks used in ILUMA devices are fully sealed, which helps to keep the moisture and freshness until use. This adds to the consistency of each session.
4. Back-to-Back Sessions Without Recharge
With older models like IQOS 3 DUO, you could do two sessions back to back before needing to recharge the holder. Good news, ILUMA i and ILUMA devices keep this feature; you can do back-to-back.
What’s different is that ILUMA i manages power better, so you get more performance over time and recharging the holder and pocket charger feels faster and smoother.
5. Device Reliability and Durability
One of the most common issues in older IQOS models was blade breakage. Even with careful handling, users would sometimes break the blade while cleaning or inserting a HEETS stick too hard.
With ILUMA’s induction system, there is no blade to break. That alone makes it a more robust and reliable option for long-term use. This means fewer service issues, fewer device replacements and less frustration for the user.
If you’ve ever had to replace a device because of a broken blade, you’ll love this upgrade.
6. Intelligent Features: Autostart, Gestures, and More
The ILUMA i isn’t just about better heating—it also has smart features that make it more user-friendly. These include:
- Autostart/Autostop: The device can detect when you put a TEREA stick in and start heating for you.
- Smart Gestures: Subtle vibrations and light indicators tell you about battery levels, heating status and session duration.
- Improved Haptics: The ILUMA i gives you clearer vibrations when your session is ready or about to end so you don’t have to look at the device.
These small things make a big difference in daily use.
7. Design and Customisation Options
Previous models like IQOS 3 and 3 DUO had limited color options and a more industrial design. With the ILUMA and especially the ILUMA i, there’s a move towards sleeker design and more personalisation.
You can now choose from multiple colors and finishes and swappable accessories like:
- Ring caps
- Holder wraps
- Door covers
This level of customization wasn’t available before and lets you express yourself while still having the same tech.

8. Better Draw and Taste Consistency
Flavor consistency is one of the most underrated but important parts of a good IQOS experience. With older models, you might find some HEETS sticks felt underpowered or burnt unevenly.
Thanks to the Smartcore Induction System, ILUMA gives you a more even draw and flavor across every stick. It also improves airflow by removing the internal blade mechanics that used to get clogged over time.
Users say the first draw is as good as the last, something earlier models struggled to achieve.
9. Stick Compatibility: TEREA vs. HEETS
Important to note: ILUMA i is only compatible with TEREA sticks, which are designed for induction heating. HEETS sticks used with previous models like IQOS 3 DUO will not work with ILUMA series.
This might be a bummer for some who have a stockpile of HEETS. But the upside is TEREA sticks are fully sealed, no tobacco leaks and a cleaner experience.

10. Overall User Experience
In summary, using IQOS ILUMA just feels smoother, faster and cleaner. From unboxing to daily use, there’s a noticeable jump in ease of use, flavor and long-term reliability.
Even small things—like not having to clean the device or not worrying about blade damage—add up to make ILUMA i feel like a more advanced product.
