How does a clogged cabin air filter affect the air conditioning performance in my Mercedes-Benz E-Class?

I think the cabin air filter in my Mercedes-Benz E-Class might be clogged. How does a dirty o r clogged cabin air filter impact the AC system’s ability to blow cold air? Can it cause weak airflow o r bad odor inside the car?

A clogged cabin air filter can significantly reduce the efficiency of your Mercedes-Benz E-Class air conditioning system. When the filter is dirty o r blocked:

Airflow through the AC vents becomes weak, making it difficult for cold air to circulate inside the cabin.

The system has to work harder to push air through the clogged filter, which can strain the blower motor.

It can cause unpleasant odors due to trapped dust, pollen, and moisture buildup.

In severe cases, it can lead to foggy windows o r increased allergens inside the car.

Regular replacement of the cabin air filter ensures better air quality, stronger airflow, and optimal AC performance.
