B Cefiro A33 (especially in versions with air conditioning) the cabin filter plays an even more important role. The fact is that the climate control system of this car is sensitive to air quality: if the filter is clogged, the cooling/heating efficiency drops by 20–30%, and fuel consumption may increase due to increased engine load. Additionally, the moist environment inside a clogged filter becomes an ideal breeding ground for bacteria and mold, resulting in a persistent musty odor.

⚠️ Attention: if in the cabin Cefiro A33 There is a smell of dampness or mold, this is a sure sign that the filter is not only dirty, but has also become a source of harmful microorganisms.
