You want to go for a drive but your car stinks. Someone smells, someone smokes, your kid pooped, you lent the car to a relative and now… someone spilled cologne, you drove through a medical lab where they test viruses… you get the idea. In any event, you need an air purifier in your car. This is the only model of a smaller size that we truly recommend for a car. There are other models that we can say are probably better than nothing, but if you are serious, then this the Philips Go Pure SlimLine is the one you should buy.
