Can you do the same test in the car Tesla model S who had a medical quality HEPA Filter , please ?


Cabin air filter seems to clean particulates effectively, and as you said, it will not work this good against gases (like NO2, VOCs). Did you perform some tests with gases too? Since some cars might only have an activated carbon filter (like my fiesta), then using a car air purifier would make sense in places like Delhi.


It depends on the filter efficiency rating of the vehicle manufacturer. Having used the Dylos and other improved particles with algorithms that convert to mass concentration, I found many vehicles in India with less than desirable ac cabin filter results ( most were nowhere as good as the Mazda or the Uber in your tests). Not surprisingly the foreign car manufacturers’ results were as good as the Mazda. Some European vehicles have HEPA filter too.

I think car air purifiers are an excellent concept. Thanks for sharing this article!
