Tesla has recently uploaded a video to its YouTube channel showing off the capabilities of the HEPA filter which is included on the Model S and Model X. The car can be programmed to enter “bioweapon defense mode” which helps keep particles and other nasty things in the air out of the interior.

In the video, Tesla pits a BMW SUV up against its own Model X and uses a smoke bombs to demonstrate how the filters work in either car.


Tesla say that the filter included in the Model X is “100 times more effective than premium automotive filters” and it can remove “at least 99.97% of fine particulate matter and gaseous pollutants, as well as bacteria, viruses, pollen and mold spores.”

The Model 3 doesn’t have the HEPA filter, but the larger Model Y does – this is due to the lack of space in the smaller car.
