Tesla Hospital-Grade (HEPA) Air Filters in Model S & X Help During California Wild Fires

The Tesla HEPA Filter and Bioweapon Defense Mode, once again is proving its worth amid California’s ongoing wildfire disaster. The air-cleaning feature for the Model S and Model X may have become an invaluable resource in times of natural disaster. 

Smoke from wildfires, like the ones currently spreading in California, is a great risk to children, the elderly, and the people with heart and lung diseases, stated the Centers for Disease Control and Prevention. According to the CDC, most children’s airways aren’t fully developed at such a young age, and they breathe in more air than adults.

The federal agency advised people to keep indoor air clean if they must stay indoors by running the air conditioner. It reminds people to close the fresh-air intake component to prevent smoke from getting inside and to ensure the filter is always clean.

During a natural disaster, people need all the resources they can get, and having a car like the Model S and Model X could be invaluable. The fact that Tesla took the time to add such a feature—not found in any other vehicle—highlights the heart underlying the company’s principles.

Tesla Model S & X have hospital-grade (HEPA) air filters. 3 & Y are really good too. This has a big effect on health. https://t.co/48s5D3IfWs

HEPA is a high-performance molecular air filter whose efficiency can reach more than 99.97%, allowing effective filtration of pollutants such as smoke, dust, and bacteria. The stronger the filterability, the smaller the air intake per unit area. To ensure adequate air supply, the Tesla HEPA filter element is very large.


The filter that Mask holds is a regular air conditioner filter, and the filter below is a Model X HEPA filter.

In a Tesla test, the HEPA air filtration system completed air purification in the Model X cab in less than two minutes, lowering the PM 2.5 pollution index from 1000 to an extremely low level (below the reference level).

When Elon Musk introduced Bioweapon Defense Mode during the Model X unveiling, people may have laughed and thought it was just a cool feature. Unfortunately, the times have recently shown that it may be a necessary feature as well. Between the wildfires in California and Australia and the spread of the coronavirus, the need to keep the air clean has become increasingly relevant. Tesla's HEPA filters in the Model S and Model X do their part to help.
