How To Clean BMW F10 AC System - Mannol 9971 + MannFilter PM2.5

I do not like foam cleaners. They leave behind a sticky muck and that can ruin the flaps in the ducting and the fan on the radiator. Gas cleaners are much better

I have bought ozone generator from china and it does the trick

sorry to say it it's not air filter it's a pollen filter or cabin filter
