Tesla’s air filters can clean polluted air 83% times dirtier than the quality of air the EPA considers good.

When Tesla had disclosed that it’s Model X and eventually its Model S cars would be fitted with HEPA filters that would be so effective so as to protect against bioweapons, consumers and car enthusiasts welcomed the news but were left wondering whether this is only marketing talking or whether Tesla would actually deliver on its talk. Can its cars really save the occupants from air-borne bioweapons?

Before the skeptics weigh in with their opinions, Tesla has now released details of its in-house testing with HEPA filters such that its Bioweapon Defense Mode can clean the air so thoroughly it borders on overkill.

In its in-house testing, Tesla engineers have exposed the Model X into a confined space whose air quality is 83% dirtier than EPA’s “good” rating. After its Bioweapon Defense Mode is activated, its filters render the air so clean that its sensors are unable to detect whatever pollution was there earlier.

Tesla claims that its cars fitted with its filters can drive through a “military grade” attack without there being any noticeable change in air quality. In fact, Tesla says, its filters clean the air even outside the car.

The filtration system is constantly being reviewed and tweaked. So, when the filters are upgraded and replaced, don’t be surprise by the fact that the interiors of the EV may seem even cleaner than when you bought it and it was all brand new.

With pollution levels peaking in cities such as Beijing, which was shut down due to smog, although the tests bring about some bragging rights, in practical terms the thoroughness of its air filters goes only to point at its over-the-top engineering and the impressive quality of its products.
