I got this car air purifier for my work car. I work in law enforcement field which requires being inside the car a lot. I can't tell for sure if it purifies the air inside the car because I don't have any tools to check that. However, I can say that I don't smell any unwanted odors inside my car anymore. It also has a nice blue backlight. #Ecobreezehttp://www.amazon.com/dp/B01AS1U0Q4
