definitely right choice cause pm2/pm2.5 is the real problem and protection in this filters are better compared to standard active charcoal one.
Mann FP is patented, Mahle-dind't found concrete info.
also check for Corteco/Freudenberg micron air blue.
I stopped using the FRAM in cabin filters with the carbon because the airflow decreased a lot in both our vehicles. Sure it blocked out a lot of nasty stuff but it blocked the air also. Turning up full blast felt like it was halfway turned up and is making the A/C knit working overtime to push through the filter. I ended up going back to the basic $10 filters that have decent amount of pleats. Works better, cheaper and less wear/tear on the A/C unit.
