Wholesale Car Air Conditioner Filter Use HEPA Grade Filter Material For High Efficiency Filtration
The automotive air conditioning filter (AACF) in passenger cars is a core component that ensures in-car air quality and the health of the air conditioning system. Its primary function is to filter out impurities, harmful gases, and microorganisms from the air entering the vehicle, while also protecting the air conditioner evaporator and blower, and improving driving comfort. Its core features can be expanded from various dimensions such as filtering function, structural design, material properties, and applicable scenarios, as follows:
Basic Filtration: Intercepts Physical Impurities
Filters: Airborne solid impurities such as dust, pollen, catkins, PM10 (particles with a diameter greater than 10μm), dead insects, and road dust.
Filtration Refinement: Mainstream basic filter elements (such as ordinary paper filters) can filter particles greater than 5μm, with an interception efficiency of approximately 80%-90%. This prevents impurities from entering the air duct and accumulating on the evaporator surface, thereby preventing unpleasant air odors and air volume reduction.
Structural Design: Adapts to the AC duct, balancing efficiency and ease of maintenance.
1. Appearance: Customized to fit the duct
The appearance of passenger car air conditioning filters is not standardized but customized according to the duct dimensions of each vehicle. Common shapes include:
Rectangular/Trapezoidal: This shape is commonly used in mainstream family sedans (such as Toyota and Volkswagen models). Sponge sealing strips are placed around the edges to ensure complete airflow through the filter media, preventing unfiltered air leakage.
Irregular Shape: Some luxury models (such as Mercedes-Benz and BMW series) have unique duct designs, resulting in filter elements with irregular shapes (such as curves or notches). These filters must be precisely matched to the vehicle model to avoid misalignment.
