Mann Filter cabin air filter CUK 2533-2 — carbon-activated, OE-fit pollen and odour removal

The Mann Filter CUK 2533-2 is a carbon-activated combo cabin filter that removes dust, pollen and many common vehicle odors and gases to improve in-car air quality.

Installed behind your vehicle’s glove box or intake plenum, the CUK 2533-2 combines a non-woven particle layer, an activated charcoal layer and a carrier media for mechanical and electrostatic filtration plus adsorption of gaseous pollutants. Manufactured and marketed by Mann Hummel under the Mann Filter name, this is an OE-style replacement designed to restore the original fit, seal and filtration efficiency of your vehicle’s HVAC system.

How does the CUK 2533-2 trap particles and gases?

The filter uses a multi-layer construction: a dense non-woven material captures pollen, dust and spores while the embedded activated charcoal adsorbs fuel fumes, ozone-related compounds and exhaust gases. A carrier layer adds structural stability so the media keeps its shape and seal for the whole service interval.

• Non-woven particle layer for mechanical filtration of solids
• Activated charcoal layer that adsorbs volatile gases and odors
• Carrier media improves durability and fit inside the filter housing

What performance can I expect over its service life?

The CUK 2533-2 is engineered to provide consistent filtration from install to replacement. Thanks to the combination of mechanical and electrostatic attraction plus the charcoal’s adsorption capacity, performance remains effective through the recommended service interval, maintaining airflow and protection.

• Consistent particle removal throughout the service period
• Charcoal layer retains gas adsorption capacity under normal conditions
• Designed to maintain proper HVAC airflow and cabin comfort

Will this fit my vehicle and how easy is it to replace?

This Mann Filter is built to OE dimensions for vehicles that specify the CUK 2533-2 or original equipment number 64 11 9 163 329. It’s shaped for a direct swap with the original cabin filter and includes the sealing edges required for an exact fit to prevent bypass of unfiltered air.

• Original equipment reference: 64 11 9 163 329
• Exact fit and seal to the manufacturer’s specification
• User-friendly replacement in the glove box or intake housing

What are the practical benefits of choosing this Mann Filter?

Beyond particle capture, the activated charcoal layer helps reduce common in-cabin odors and many gaseous pollutants encountered in urban driving. The combined filtration approach supports clearer vents, reduced debris buildup and a more consistent HVAC experience.

• Reduces pollen, spores and airborne dust inside the cabin
• Adsorbs fuel vapors, exhaust-related gases and odorous molecules
• Helps maintain HVAC efficiency and cleaner vents

Who is this for: The Mann Filter CUK 2533-2 is suited for drivers who want an OE-quality replacement cabin filter that balances particle filtration with activated-carbon gas adsorption. It’s a good match for owners of vehicles specifying this part number, those who drive in urban or high-traffic areas, or anyone seeking to reduce in-cabin dust, pollen and common road odors without altering HVAC performance.
