Mann Filter cabin air filter CUK 2533-2, carbon-activated with OE fit and activated charcoal

Mann Filter CUK 2533-2 is a carbon-activated cabin air filter that reduces pollen, dust and a range of harmful gases to improve in-car air quality.

Designed and manufactured by Mann‑Hummel, the CUK 2533-2 combines a non-woven particle layer with an activated charcoal layer and a stabilizing carrier to capture solid contaminants and adsorb gaseous pollutants. Built to exact original equipment dimensions (OE part number 64 11 9 163 329), this combo filter gives consistent performance over the recommended service interval and a reliable seal for your vehicle’s HVAC intake.

How does this cabin filter remove both particles and gases?

The CUK 2533-2 uses a multi-layer construction: a mechanical/electrostatic non-woven layer traps pollen, dust and spores, while a carbon-impregnated layer adsorbs nitrogen dioxide, fuel vapors and ozone. The carrier media keeps the layers stable and ensures even airflow across the filter surface for sustained efficiency.

• Non-woven particle layer captures airborne solids and allergens.
• Activated charcoal layer adsorbs volatile gases and odors.
• Carrier media prevents deformation and maintains airflow.
• Engineered to the OE dimension for a tight, leak-free fit.

What performance can I expect throughout the service interval?

Mann designs the filter media to sustain filtration efficiency from installation until the recommended replacement interval. The combination of mechanical and electrostatic attraction keeps particle capture high, while the carbon layer retains gas-adsorption capacity under normal driving conditions.

• Stable particle filtration for the full service life.
• Continuous adsorption of common traffic-related gases.
• Minimal airflow restriction to preserve HVAC performance.
• Fits exact OE shape to avoid bypass and maintain efficiency.

Is the CUK 2533-2 easy to install and which vehicles fit it?

The filter follows the original equipment dimensions and clip locations to match the factory cabin filter housing, so installation is typically straightforward for anyone comfortable with basic vehicle maintenance. Always verify fitment with your vehicle make, model and year or compare part number 64 11 9 163 329 to the existing unit before purchase.

• OE-style fit for simple, secure installation.
• Check compatibility using the provided part number.
• Replacement requires no special tools for most vehicles.
• Designed to seal to the housing and prevent unfiltered air entry.

Who is this for? The Mann Filter CUK 2533-2 is aimed at drivers who want both particle filtration and active removal of common urban gases and odors—commuters, city drivers exposed to traffic pollution, allergy sufferers, and anyone seeking to maintain cleaner cabin air between service intervals. If you need an OEM-matching cabin filter that balances mechanical particle capture with activated-carbon gas adsorption and a secure fit to your vehicle’s HVAC, this Mann Filter is a practical choice.
