Customized Passenger Car Air Conditioning Filters Can Be Customized
For All Models Easy To Install
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
Advanced Filtration: Absorbs Harmful Gases and Odors
Filters: Carbon monoxide (CO), nitrogen oxides (NOx), and sulfur
dioxide (SO₂) from vehicle exhaust, as well as ambient air fumes,
industrial waste, and formaldehyde (small amounts) emitted from
interior trim, benzene, and other substances.
Implementation: Adding an activated carbon layer (granular
activated carbon or honeycomb activated carbon) to the base filter
material. The porous structure of the activated carbon absorbs
harmful gases and odor molecules, with an adsorption capacity of
typically 50-100g/㎡ (replacement is required upon saturation,
otherwise odor will be released).
Core Applications: Suitable for use in congested areas, industrial
areas, and areas with high levels of oil smoke. It significantly
reduces in-vehicle odors (such as exhaust and oil smoke) and
improves air freshness.
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.
