IQOS vs E-Cigarettes: What’s the difference?

IQOS and e-cigarettes are both smoke-free alternatives to cigarettes for adults who would otherwise continue to smoke or use other nicotine products.

Both are electronic devices, and do not generate smoke like cigarettes. But there is one feature that distinguishes IQOS device from e-cigarettes: Contrary to vaporizing an e-liquid, IQOS heats real tobacco, releasing tobacco vapor.

What are e-cigarettes?

E-cigarettes are electronic hand-held devices that are smoke-free alternative to cigarettes. In general, they are powered by a battery and heat e-liquids in order to generate an aerosol or what some users call vapor. The e-liquids may have various flavors and may contain nicotine.

How do E-Cigarettes work?

There are many types of e-cigarettes. They differ in size, power, customization options, and even their ability to be reusable or disposable. However, most of them work on the same principle and with similar components.

The principle:

E-cigarettes heat and vaporize e-liquids in a wide range of temperature from 100 ⁰C - 250 ⁰C. They achieve this by drawing the liquid from a tank and putting it in contact with a battery powered heating element. When the liquid is evaporated it is drawn from the device thorough a mouthpiece.

The components:

The battery - The energy source for the whole device. In most cases it is rechargeable and provides power to the heating element and electronic components.

The tank - The container that is used to store the liquid until it is taken to the heating element or chamber. Some e-cigarettes use capsules or pods that are disposable.

The e-liquid - The mixture that is vaporized inside the e-cigarette. While there are many variants of the liquids, they usually contain propylene glycol, glycerin, nicotine, flavorings and various additives.

The heater - The set of components that draw the liquid toward the heating element and heat to vaporize. Most e-cigarettes use a “wick and coil” system. The wick naturally soaks the liquid and puts it in contact with the metal coil which is the part that heats.

The sensors and electric components - Control the heating and operation of the device. They range from simple push to activate buttons, LEDs, battery Indicators or to advanced flow sensors.

The mouthpiece - The chamber or channel where the vaporized liquid drawn from the device.

What is IQOS?

IQOS is an electronic device developed by Philip Morris International that uses an innovative tobacco heating system called HeatControl™ Technology. This type of tobacco heating technology is often called “heat-not-burn”, because it heats tobacco instead of burning it – which is what happens with cigarettes.

Ceramic blade in the IQOS device heats the tobacco from the inside and does not burn it, as it is done when smoking cigarettes. Rather, the tobacco heats to a maximum of 350 degrees C – much lower than cigarettes, which burn at temperatures around 600 degrees C. IQOS produces no fire, no ash and no smoke. While IQOS is not risk free, it emits on average 95% lower levels of harmful chemicals compared to cigarettes and allows IQOS adult users to experience tobacco with less chances to bother people around them.

Currently, there are two options of IQOS devices to choose from: IQOS 3 DUO and IQOS 2.4 Plus. Some IQOS devices have a separate holder and charger, while others have those components integrated as an all-in-one device. These different options allow adult users to select IQOS device that best suits their lifestyle.
