Review on Bosch Automotive 6055C High Efficiency Cabin Air Filter for Dodge Durango (2011-2019) & Jeep Grand Cherokee (2011-2019) by Tony Jockheck

. Local BAAQMB PM2.5 AQI data for reference. the reading was 163. The reading in the car at start was 159. Filtration using a used Toyota OEM filter reduced PM2.5 particles to 55-57 and no more after 40 minutes. Anything below 50 is healthy The area AQI was 137. The car interior reading at start was 127. This Bosch filter reduced particulates to an AQI=4 (four) after 10 minutes. In both tests, the air conditioning was switched off and the fan was running at full speed. only room air. Temperature approx. The Toyota 67-F.OEM filter was thin with wide gaps between the ribs. The Bosch block is thicker and has a narrower comb gap. Now the question is how long will it last.
