Best solution to keep out bad smells is to change the filter at least 1x a year.
Once that air flow decreases through the heating/cooling system that is the start of potential issues.
Poor air flow increases humidity levels in the system. Add the darkness of the system and any organic material like dust/dirt in it and you now have a breading ground for mold.
You might actually begin to see it first if you are lucky on the filter material itself. If it gets into your system itself you may be looking at one large repair bill to rid it out of the vehicle.
Smells are a good indicator that things are not well in the heating cooling system. With good air flow mold can not grow. Thus keeping that filter clean provides good air flow.
There is mold all over, as it is part of the environment. The job is to just prevent if from active growth and keep it dormant.
Just a suggestion.
