What is the function of ION in Geely cars?

[Logan]

ION in Geely cars refers to the air purification function. When ION is activated, the air purifier starts working. Below is a detailed introduction to the car ION system: 1. Composition: Consists of a PM2.5 sensor and a negative ion generator. 2. PM2.5 sensor: Function: It measures the PM2.5 content in the air inside and outside the vehicle, serving as the basis for whether to automatically activate ION, and displays the measured PM2.5 concentration on the car's infotainment screen. Location: The sensor is installed inside the vehicle's dashboard, to the right of the blower and on the right front A-pillar. 3. Negative ion generator: Function: It boosts the 12V low voltage to hundreds of volts of high voltage, ionizing the air to form negative ions, thereby purifying the air, removing dust, odors, and sterilizing. Location: Installed between the blower and the evaporator box.
