Are we talking about the cabin air filter? and do you know of any 3rd party suitable replacements?

Post append: According to [1], a simple activated charcoal cabin air filter is better than the stock one in removing diesel exhaust particles.

Thanks, I didn't know this paper. We just measure the NO2.

edit: Seriously, how did they get that through the ethics committee.. I'm astonished and a little bit appalled. There is a second study too.

Yes, the issue is the cabin air filter. The simple paper pollen filters don't do anything against NO2 - we measure the same values inside and outside.

Most filters with active charcoal will reduce the NO2 concentration a lot. It is recommended to replace them after 1-2 years or a certain distance, but we don't have numbers on this - still, it is clear the filters degrade after a while.
