Tesla’s air filtration system with “Bioweapon Defense Mode” is proving useful for the owners affected by the current wildfires in California.

Watch an owner using the system while going through a hellish-looking road with scary air quality.

With the Model X, Tesla put a lot of effort into developing a more powerful air filtering system in order to not only contribute to the reduction of local air pollution with electric vehicles, but also to reduce the direct impact of air pollution on the occupants of its vehicles.
