Powerful Auto Air Purifier: 4WDKING Ionic Air Purifier can release up to 5.6 million negative ions per cm3, which can immediately remove bad order and smell from the car. These high-density negative ions also attach dust, pollen, and smoke to increase air quality and reduce the odor and smell.
Efficient Car Odor Remove: The air purifier emits a light scent of ozone that smells similar to a summer rain shower. The negative ion that releases can neutralize the odor. The ozone is most effective in purifying when used over a period of time.
