Original MANN-FILTER Interior Filter FP 2358 – FreciousPlus biofunctional pollen filter – For passenger cars

MANN‑FILTER Interior Filter FP 2358 – FreciousPlus Biofunctional Pollen Filter

The FP 2358 is a premium cabin air filter engineered by MANN‑FILTER to deliver superior protection for the interior atmosphere of passenger vehicles. Designed with advanced biofunctional technology, it captures pollen, allergens, dust particles and volatile organic compounds (VOCs) while maintaining optimal airflow.

Key Design Features

• Biofunctional Pollen Filter: Incorporates a specialized polyphenol layer that actively neutralises pollen molecules, reducing allergic reactions for occupants.
• Activated Carbon Core: Provides high adsorption capacity for odors and harmful gases, ensuring fresh cabin air even in polluted environments.
• High‑Efficiency Particulate Filter (HEPA‑like): Captures particles as small as 0.3 µm with a filtration efficiency exceeding 99%, protecting the HVAC system from particulate buildup.
• Low Pressure Drop: Engineered to minimise resistance, preserving engine performance and cabin comfort while maintaining airflow rates.
• Durable Construction: Made from high‑grade polypropylene and reinforced with a moisture‑resistant backing, the filter resists degradation in humid conditions.

Performance Highlights

The FP 2358 delivers an impressive balance between filtration efficiency and airflow. In laboratory tests, it achieved:

• Pollen capture rate: > 99.5%
• Particulate removal (PM2.5): > 99.9%
• VOC adsorption capacity: 95% reduction of common indoor pollutants
• Pressure drop at 200 L/min airflow: < 0.3 kPa, ensuring minimal impact on HVAC operation.

Compatibility and Installation

The FP 2358 is specifically engineered for a wide range of passenger cars, including models from Honda (Accord, Civic, CR‑V), Great Wall, Haval, and other OEMs that use the standard FP 2358 cavity. The filter’s dimensions match the original MANN‑FILTER interior filter size, allowing a direct fit without modifications.

Installation Steps:

1. Locate the cabin air filter housing behind the glove compartment or under the dashboard.
2. Open the housing cover and remove the old filter carefully to avoid contaminating the interior.
3. Insert the FP 2358 with the airflow arrow pointing towards the HVAC intake.
4. Secure the housing cover, ensuring a tight seal to prevent unfiltered air from bypassing the filter.

Maintenance Guidelines

• Check the filter every 12–15 months or after extensive exposure to dusty conditions (e.g., construction sites).
• Avoid using compressed air to clean the filter; replace it instead to maintain optimal performance.
• Inspect for visible damage or excessive wear before each replacement cycle.

Environmental and Health Benefits

The combination of biofunctional pollen treatment and activated carbon filtration not only improves air quality but also contributes to a healthier driving environment. By reducing airborne allergens, the FP 2358 helps alleviate symptoms for individuals with hay fever, asthma, or other respiratory sensitivities.
