What does the ion button in a car mean?

The ion button in a car refers to the vehicle's negative ion air purification function. When this function is activated, the negative ion generator produces and releases a large number of negative ions. Since dust, particles, and harmful substances like formaldehyde in the air easily adhere to these negative ions, they form larger particles and settle down, ultimately being filtered out by the air filter. This achieves the effect of purifying the air inside the car. In simple terms, the negative ion air purification function in a vehicle transforms tiny particles that cannot be filtered by the air filter into larger particles that can be filtered, through adsorption with negative ions, thereby achieving purification.
That ION button, I use it every day in my car and find it super practical. While driving, there are always various odors inside the car—like foot odor, food smells, or outside pollution seeping in. With just a press of that button, it activates the ion generator, releasing negative ions to purify the air. This thing effectively captures dust and pollen, easing my allergy issues, especially during pollen-heavy spring. I feel it works really well with the car's air conditioning system—once turned on, the air instantly feels fresher, like breathing in a forest after rain. Also, remember to check this function during car maintenance to ensure the electrodes aren’t clogged, otherwise the effect will diminish. Overall, for me, it’s a little health helper, reducing the need for chemical sprays inside the car.
