I use Atmotube Pro to measure PM1, PM2.5, PM10 and VOCs in my car. I found these Bosch Automotive Cabin Air Filters to be extremely effective at fine dust (PM) filtration; however, they do not filter total volatile organic compounds (VOCs) well. I live in a very polluted environment, so I often use good quality cabin filters while driving. I've found that to get truly clean air in my car, I first have to turn the car's airflow off until the VOC levels go down according to the Atmotube Pro gauge, and then turn the airflow back on for the filter to clean Residual air from solid particles. That's what's doing the work at this point. It also doesn't have carbon filtration, so it doesn't clean the air of odors. For what I need it for, fine dust, this is the best cabin filter I've found so far.
