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.
