Functions of PM2.5 Automotive Air Conditioning Filters The core function of a PM2.5 automotive air conditioning filter is to efficiently filter fine particles (≤2.5 microns in diameter) in the air, while blocking impurities like dust, pollen and odors, creating a clean breathing environment inside the vehicle. Its specific functions are as follows: 1. Filter fine pollutants: It effectively blocks PM2.5 (e.g., smog, industrial dust) and fine particles in vehicle exhaust, preventing them from entering the car via the air conditioning system and reducing respiratory irritation for drivers and passengers. 2. Block allergens: It filters allergens such as pollen, mold spores and insect debris, lowering allergy risks for people with allergies when in the vehicle. 3. Improve in-vehicle air quality: Some products have an activated carbon layer to absorb formaldehyde and odors (e.g., exhaust smell, external odors), further enhancing air freshness inside the vehicle.
