In the midst of the wildfires in Canada, some Tesla drivers are relying on the “Bioweapon Defense Mode” that comes with certain models and serves as an additional air pressure buffer on top of the models' normal HEPA filtration.
Elon Musk has been anything but silent when it comes to his plans for Tesla and home HVAC and his admiration for heat pump technology. Inspired by the air filtration systems used in hospitals, clean rooms, and the space industry, Tesla developed its own in-vehicle HEPA filtration system that was first incorporated in Model Y, then Model 3, and since then has been most recently introduced in the refreshed Model S and X. In fact, all new Tesla electric vehicles, as a standard, come with a heat pump.
