What is the function of the car air conditioner ION?

[Carter]

ION refers to the air purification function. When ION is activated, the air purifier starts working. The new ION system mainly consists of two components: a PM2.5 sensor and a negative ion generator. The specific introduction is as follows: 1. PM2.5 sensor: Its function is to measure the PM2.5 content in the air inside and outside the car, serving as the basis for whether to automatically activate ION and displaying the measured PM2.5 concentration on the car's screen. This sensor is installed inside the vehicle's dashboard, to the right of the blower and on the right front A-pillar. 2. Negative ion generator: It boosts the 12V low voltage to hundreds of volts of high voltage, ionizing the air to form negative ions for air purification, dust removal, deodorization, and sterilization. It is installed between the blower and the evaporator.
