Tesla this week really seems intent on letting the world know about the “Bioweapon Defense Mode” feature it debuted on the Model X. In a blogpost published earlier this week, Tesla posted some interesting scientific data highlighting the effectiveness of its air filtration system.

As Tesla tells it, when a driver turns on the Bioweapon Defense Mode feature, the Model X’s air filter is 300 times more effective at filtering out bacteria, 700 times more effective at filtering smog and an impressive 800 times more effective at filtering out viruses.

“Inspired by the air filtration systems used in hospitals, clean rooms, and the space industry,” Tesla writes, “we developed a HEPA filtration system capable of stripping the outside air of pollen, bacteria, and pollution before they enter the cabin and systematically scrubbing the air inside the cabin to eliminate any trace of these particles. ”

“The end result,” Tesla continues, “is a filtration system hundreds of times more efficient than standard automotive filters, capable of providing the driver and her passengers with the best possible cabin air quality no matter what is happening in the environment around them.”

Putting their money where there mouth is, Tesla late on Monday published a video to Twitter which highlights how the air pollution level inside a car drops drastically when Bioweapon Defense Mode is engaged.
