When it comes to the best car air purifiers, the Westinghouse 1804 stands out with its excellent purification tech.

With this machine, allergens, pollutants, bacteria, and other unwanted debris pass through the pre-filter screen and the static filter, which then enters the medical-grade H13 HEPA filter. The air then passes the Oxygen generator, which sterilizes it, before finally entering the NCCO rector, which uses nanotechnology that destroys harmful matter in the air.

The unit itself, while perhaps slightly larger compared to some of the other options in this breakdown, is light-weight, quite portable and even has a built-in carrying handle so it can be taken from your car, to a plane, to a hotel and will even last about 8 hours on a charge.

Overall, this option by Westinghouse takes the number one spot on our list because it is high-quality, effective, and fully featured.
