Mann Filter Cabin Air Filter CUK 2941-2 — Activated Charcoal Direct-Fit, Particle Protection

The Mann Filter CUK 2941-2 is a combo cabin air filter with a particle layer and an activated charcoal core designed to trap pollen, dust and common vehicle exhaust gases for a cleaner cabin atmosphere.

Designed and produced by Mann Hummel, the Mann Filter CUK 2941-2 combines non-woven particle media with an embedded activated charcoal layer and a supporting carrier to provide stable, long-lasting filtration inside the vehicle cabin. The construction uses mechanical and electrostatic attraction to capture solid particulates while the charcoal adsorbs a range of gaseous pollutants. Intended as a direct-fit replacement for vehicles using the matching OEM part number, this filter focuses on reliable performance and consistent efficiency over the service interval.

How does the CUK 2941-2 filter the air in my car?

The filter uses a multi-layer structure: a non-woven particle filter to capture pollen, spores and dust; an activated charcoal layer to adsorb odors and gaseous contaminants; and a carrier media to keep the assembly rigid and sealed. Mechanical trapping and electrostatic attraction work together to maintain high filtration efficiency throughout the filter’s life.

• Non-woven particle layer captures airborne solids like pollen and dust
• Activated charcoal adsorbs nitrogen dioxide, fuel vapors and ozone
• Carrier media ensures shape and an exact fit to the housing
• Combination of mechanical and electrostatic filtration for durability

How do I know this is the correct replacement for my vehicle?

The Mann Filter CUK 2941-2 corresponds to the OEM reference 64 31 6 945 586 and is manufactured to match the original equipment’s dimensions and sealing surfaces. This direct-fit design reduces installation effort and helps prevent bypass where untreated air could enter the cabin.

• OEM part number cross-reference: 64 31 6 945 586
• Designed for exact fit and reliable sealing in the filter housing
• Compatible with vehicles that specify the matching OEM reference
• Sold as a single replacement element for standard service intervals

What maintenance and service expectations should I have?

Cabin filters like the CUK 2941-2 are maintenance items typically replaced at regular service intervals or when airflow and interior air quality decline. Replacement frequency varies by driving environment; urban or high-pollen regions usually require more frequent changes than low-traffic rural areas.

• Inspect during scheduled service or when reduced airflow is noticed
• Replace according to vehicle manufacturer or every 12–24 months depending on conditions
• Consistent filtration performance maintained throughout the service life
• Ensure proper installation to preserve the filter’s sealing and efficiency

What are the construction and performance highlights of this filter?

The CUK 2941-2 uses advanced media engineering: a fine-pore non-woven matrix for particulate capture and a charcoal layer whose pores are far finer than human hair to adsorb gases. Mann Hummel’s manufacturing and quality control align the part with original equipment expectations, aiming for consistent filtration across the product’s lifespan.

• Triple-layer design: particle media, activated charcoal, and carrier support
• Pores in the charcoal layer are microscopically small for efficient adsorption
• Engineering focused on long-term, consistent filtration performance
• Manufactured by Mann Hummel, a longstanding OEM supplier since 1941

Who is this for: Drivers who want a direct-fit replacement cabin filter that balances particulate capture with gas and odor adsorption. The Mann Filter CUK 2941-2 suits owners of vehicles using the OEM reference 64 31 6 945 586 or anyone seeking a factory-style combo filter to help maintain cabin comfort and the HVAC system’s airflow. It is especially relevant for people in urban environments, regions with seasonal pollen, or those looking for an OEM-quality part to preserve vehicle interior air handling performance.
