Increase the air circulation and purify the air in your car. Clear out the odor and never worry about your car smelling again. This car air purifier will help improve the quality of the air inside your car by removing particles such as pollen, dust and dirt. This 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.
