The MANN-FILTER CUK 25 001 is designed for BMW 1 Series (F20/F21) vehicles and features a unique Activated Carbon layer, unlike standard filters. This special structure traps not only dust and pollen but also exhaust odors, harmful gases (ozone, nitrogen oxides), and unpleasant smells at a rate of 95%, preventing them from entering the cabin.
- Odor and Gas Removal: The activated carbon layer works like a sponge, preventing exhaust odors from entering the cabin during tunnel passages or heavy traffic.
- Special Curved Design: It is fully compatible with the curved filter housing (Banana Type) under the dashboard of BMW F-Series vehicles, ensuring no breakage during installation.
- Allergen Protection: It filters pollen, spores, and bacteria, creating a clean air space for allergy sufferers and children.
- Fog Prevention: It ensures the efficient operation of the air conditioning system, delaying fog formation on the windows.

Frequently Asked Questions (FAQ)
Why should I choose a carbon cabin filter? Standard (white) filters only trap dust. Carbon (gray) filters absorb unpleasant odors, exhaust fumes, and harmful gases due to their chemically treated surfaces. Carbon filters are particularly recommended for those driving in urban traffic for health reasons.
Where is the BMW F20 cabin filter located? In BMW 1 Series (F20) vehicles, the cabin filter is located behind the plastic cover under the glove compartment on the front passenger side. To replace it, the screws under the glove compartment need to be removed.
Is the installation direction important? Yes, it is very important. The "AIR FLOW" arrows on the filter indicate the direction of air entering the cabin (usually from the engine into the cabin). If installed incorrectly, filtering efficiency decreases and it may produce noise.
Which vehicles is it compatible with? This filter is compatible with many models that share the same platform: it fits all BMW 1 Series (F20), 2 Series (F22 Coupe), 3 Series (F30 Sedan), and 4 Series (F32/F36 Gran Coupe) models.
