Customized Structure Passenger Car Cabin Filter Is Suitable For Nissan Full Range Of Models

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
 

High-end Filtration: Intercepts Fine Particles and Microorganisms

Filters: PM2.5 (fine particles ≤ 2.5μm in diameter, such as smog and industrial dust), bacteria (such as E. coli and Staphylococcus aureus), viruses (select models can filter), mold spores, etc.

Method:
Uses HEPA-grade filter media (such as glass fiber and ultrafine synthetic fiber) with a filtration accuracy of up to 0.3μm and a PM2.5 interception efficiency of ≥95% (some high-end models reach 99.97%, meeting N95 mask standards).

Some filter elements incorporate antimicrobial coatings (such as silver ions and nano-titanium dioxide) to inhibit bacterial growth on the filter surface, preventing the filter from becoming a breeding ground for bacteria in humid environments.

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.
