Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Air Filtration: Effectively traps dust, pollen, and airborne particles to maintain clean cabin air in Audi vehicles.
  • Odor Control: Integrated activated carbon layer neutralizes odors from smoke, cooking, and pollution, enhancing interior air quality.

Key features

  • 1. Advanced Material Technology for Enhanced Filtration

    • With a pleated structure integrated with activated carbon, this cabin air filter effectively traps dust, pollen, and allergens while neutralizing odors from smoke or pollution. Its synthetic fiber base ensures durability in harsh environments, outperforming standard non-activated carbon filters*.

  • 2. Maximized Filtration Efficiency via Pleated Design

    • The multi-pleated construction increases surface area by up to 40% compared to flat filters*, enabling superior particle capture without sacrificing airflow. This maintains cabin air quality even in dusty or polluted environments.

  • 3. OE-Compatible Fit for Audi Models

    • Engineered for Audi models like A6 Avant, S6, and Allroad (1997–2018), this filter ensures a precise fit and seamless installation, avoiding leaks or reduced efficiency common with generic alternatives.

  • 4. Odor and Pollutant Neutralization

    • With activated carbon layers, the filter actively adsorbs harmful gases, smoke, and cooking odors, creating a fresher cabin environment—ideal for long drives or urban commuting.

  • 5. Long-Lasting Performance and Versatility

    • Designed for continuous use across seasonal conditions, this filter maintains efficacy in varied climates and road environments. Its synthetic fiber core resists degradation, extending lifespan compared to standard paper-based filters*.

  • Notes:

    • Material Technology: Highlighted activated carbon and synthetic fibers for odor/particle filtration.

Supplier's note

  1. Technical Breakthroughs:

    • Activated Carbon Layer: Triple the odor-adsorption capacity of standard filters, neutralizing even persistent fumes.
    • Pleated Design: 40% larger surface area than flat filters, boosting airflow by 20%.
    • Synthetic Fiber Blend: 30% lighter than fiberglass alternatives while maintaining structural integrity.

  2. Version Selection Guidance:

    • Base Model: Optimal for vehicles in low-pollution areas (e.g., rural Audi A6 owners).
    • Advanced Model: Ideal for urban drivers (e.g., Audi S6 in cities) needing odor control and improved filtration.
    • Pro Model: Best for heavy-duty use (e.g., Audi Allroad in industrial zones) with its 99.5% filtration and 18-month lifespan.

Example: The Pro version’s 99.5% filtration efficiency – exceeding industry standards by 9.5% – ensures safer breathing in high-pollution zones. Paired with its activated carbon layer, it eliminates odors from traffic exhaust, creating a premium cabin environment.
