Introduction to Tesla air filter:

In this article, we will be discussing the Tesla air filter and bioweapon defense mode. We will explore how effective they are in protecting the driver and passengers from air pollution and harmful particles.

Tesla Air Filter:

The Tesla air filter is a HEPA filter that is capable of removing 99.97% of particulate matter from the air. This includes pollen, bacteria, and other harmful particles. The filter is designed to last for years and requires minimal maintenance.

Bioweapon Defense Mode:

The bioweapon defense mode is a feature that was introduced by Tesla in 2015. It is designed to protect the driver and passengers from harmful pollutants and particles in the air. The mode creates a positive pressure inside the car. All which the Tesla air filter prevents outside air from entering the cabin.

Testing the Tesla Air Filter and Bioweapon Defense Mode:

Several tests have been conducted to determine the effectiveness of the Tesla air filter and bioweapon defense mode. In one test, a Model X was placed in a bubble filled with extreme levels of pollution. The air inside the car remained clean and safe to breathe.

Air pollution has a significant and pervasive impact on public health. According to the World Health Organization, it is now considered “the world’s largest single environmental health risk,” with more than three million people dying every year as a result. This is more than twice the number of people that die in vehicle accidents each year.

Health and safety are important to us. Just as we’ve designed Model S and Model X to avoid collisions or protect their occupants when one happens, we felt compelled to protect them against the statistically more relevant hazard of air pollution*. Inspired by the air filtration systems used in hospitals. Also clean rooms, and the space industry. For they developed a HEPA filtration system. One capable of stripping the outside air of pollen, bacteria, and pollution. All before they enter the cabin and systematically scrubbing the air inside the cabin. Especially to eliminate any trace of these particles. The end result is a Tesla air filter / 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.

Placed in a Bubble


Clean like Mr Clean

Not only did the vehicle system completely scrub the cabin air. However, in the ensuing minutes, it began to vacuum the air outside the car as well. Thereby reducing PM2.5 levels by 40%. In other words, Bioweapon Defense Mode is not a marketing statement. For it is real. You can literally survive a military grade bio attack by sitting in your car.

Moreover, it will also clean the air outside your car. Thereby making things better for those around you. And while this test happened to be done with a Model X. So the same would be true of the new Model S now in production.


Tesla will continue to improve the micro-geometry and chemical passivation defenses in the primary and secondary filters. All which are easily replaceable. I mean so this will get better the longer you own your car. Suggestions for improvement are welcome.

*According to the World Health Organization, average annual PM2.5 levels (the most dangerous form of pollution) reach 56 µg/m³ in Beijing, 25 µg/m³ in Mexico City. Also 21 µg/m³ in Hong Kong. Furthermore 20 µg/m³ in Los Angeles, 20 µg/m³ in Berlin and 17 µg/m³ in Paris. Finally and 16 µg/m³ in London.

Based on the findings of a 2013 study conducted at Harvard. For these levels of pollution would result in population-averaged life expectancy reductions of 23 months in Beijing. Also 10 months in Mexico City. In addition, 9 months in Hong Kong. Furthermore, 8 months in Berlin and Los Angeles. Finally and 7 months in Paris and London.

As we see here that Tesla air filter is no joke!
