What is IQOS?

As the world moves away from traditional combustible cigarettes, several alternatives have emerged. While vaping is a popular choice, many smokers still crave the authentic taste and ritual of real tobacco. This is where IQOS comes in. But what exactly is IQOS, and why is it categorized differently from standard e-cigarettes?

1. The Science: What is Heat-Not-Burn?

The name IQOS (often interpreted as "I Quit Ordinary Smoking") represents a revolutionary technology known as Heat-Not-Burn (HNB).

Unlike traditional cigarettes that burn tobacco at temperatures exceeding 800°C, IQOS devices heat specially designed tobacco sticks to approximately 350°C. This temperature is high enough to release a nicotine-containing aerosol but low enough to prevent combustion. Because there is no fire, there is no smoke, no ash, and significantly less lingering smell.

2. IQOS vs. Vaping: The Key Differences

Many people confuse IQOS with vaping, but they are fundamentally different:

• Material: Vapes use liquid (e-juice). IQOS uses real tobacco leaf that has been processed and compressed into sticks.

• Experience: Vaping provides a wide range of fruit/dessert flavors. IQOS provides a flavor profile that is nearly identical to a traditional cigarette.

• Technology: Vapes use a coil to vaporize liquid; IQOS uses a ceramic heating blade or induction technology to heat tobacco.

3. Understanding the Models: IQOS ILUMA vs. Originals

In 2026, the IQOS ecosystem is divided into two main categories:

• IQOS Originals (Duo/One): These use the classic HeatControl™ technology with a ceramic heating blade inside the holder. They are compatible with HEETS sticks.

• IQOS ILUMA Series: The latest innovation featuring the Smartcore Induction System™. These devices have no blade (making them easier to clean) and are compatible only with TEREA sticks, which have an internal heating element.

4. Consumables: HEETS and TEREA

The tobacco sticks are the heart of the experience. They come in various "blends":

• Classic Tobacco: Ranging from light (Silver/Yellow) to full-bodied (Amber/Sienna).

• Menthol/Mint: Providing a cooling sensation (Turquoise/Blue).

• Aromatic/Capsule: Blends with hints of berries or citrus (Purple Wave/Oasis Pearl).

5. Frequently Asked Questions (FAQ)

Q1: Is IQOS safer than smoking? A: According to various studies, IQOS emits on average 95% lower levels of harmful chemicals compared to a reference cigarette. However, it is not risk-free and contains nicotine, which is addictive.

Q2: How do I clean my IQOS device? A: If you use an Originals Duo, you should use the official cleaning tool and sticks every 20 puffs. If you use the IQOS ILUMA, it requires no cleaning because the tobacco is fully sealed within the TEREA stick.

Q3: Can I use regular cigarettes in an IQOS device? A: No. IQOS is designed strictly for use with HEETS or TEREA sticks. Attempting to use a traditional cigarette will damage the device and will not work.

Q4: How long does one stick last? A: Each stick is designed to last for approximately 14 puffs or 6 minutes, which is roughly the same duration as a standard cigarette.

Q5: Why does my IQOS taste burnt? A: For blade-based models (Originals), this usually means the device needs a deep clean. For ILUMA models, ensure you are not using a damaged TEREA stick.
