The IQOS ILUMA ONE is an improved version of the hugely popular IQOS device. It has a longer battery life and more accurate temperature control, and it can also be used with other devices that use the Bluetooth® Low Energy (BLE) protocol. So, what does this mean for you? The IQOS Iluma One is a device that resembles a tobacco cigarette that uses heat-not-burn technology. It is a lot like a vape, but it is different in the fact that it has a vaporization chamber that requires a tobacco stick to be ground up. This vaporization chamber is what heats the tobacco quickly and vaporizes it, creating a vapor that is inhaled. The IQOS Iluma One offers the convenience of a cigarette but with a lower level of tar, nicotine, and other harmful chemicals.
