In a few sentences

In brief

The ordinary filter and the activated charcoal variant have a different composition and should not be described as being the same.

Useful to know

The cabin filter processes the air that passes to the interior through the ventilation system. Bosch distinguishes standard particulate filters from variants with a layer of activated carbon also designed for certain gases and odors. This is a different part of the engine air filter. [1]

The presence of activated carbon does not mean universal protection from any contamination. Choose accurate compatibility and described characteristics, not the promise of "completely clean air" in any conditions.

When changing, check the service instructions for the car and the correct direction of the air flow when it is indicated. Do not take a single run as mandatory for all models and environments. The useful question when buying is what type of filter is provided and what the specific product actually contains, not just whether the packaging looks more premium.
