The air purifier has a clean design which looked nice with the black interior of my car. With its elegant design it did not stand out too much, although it would have been nicer if the size was a little smaller as this can get knocked down when the passengers are moving about. The power cord connects to the cigarettes lighter port of the car.The air purifier has three settings- low, medium, and high. During operation, it is quiet and extremely smooth. With the usual cabin noise the sound of the purifier is completely drowned out. The air flow from the purifier is also light and does not disturb at all. A big advantage with this air purifier is that the filer can be cleaned and reused. I really liked that compared to other purifiers which require a filter replacement often. Moreover, the purifier automatically lets you know when its time to clean.My main reason for getting this was to reduce dust build-up in my car during my drive to work on a dusty road. I also wanted to reduce any odor in the car, as I eat often inside the car on my way to work. After initial testing and light use I think the dust build-up shows noticeable reduction. The odor on the other hand did not reduce much.Overall, this is a great product to control dust and pollutants in your car, but with a few negatives especially considering its price.
