Filter material: Based on cellulose paper (wood pulp paper) or non-woven fabric;
Principle: Capture large particles (>10μm) through physical methods such as mechanical interception and inertial collision;
Structure: The pleated structure increases the area, with a single material and low cost.
The filtration efficiency is relatively low, and it has no obvious filtering capacity for PM2.5, bacteria, odors, etc.
Filter material upgrade
The introduction of synthetic fiber + electrostatic electret technology (such as polypropylene electret meltblown fabric) can filter particles smaller than 1μm.
Apply a multi-layer composite material structure (coarse filter layer + fine filter layer);
Performance improvement
The PM2.5 filtration efficiency has been increased to 80-95%.
The filter material is nano-sized, with stronger uniformity and more reasonable air resistance control.
Manufacturer representative
MANN, BOSCH, MAHLE, Donaldson and others have launched the "High-Efficiency Air Filter" series.
Market characteristics: It has begun to differentiate into economical and high-performance products.
Advanced Stage: Multi-Functional + Nanotechnology (2015 - Present)
New feature integration
Antibacterial/Antiviral: Incorporating materials such as silver ions, copper ions, and photocatalytic coatings;
Deodorization/formaldehyde removal /TVOC adsorption: Activated carbon and graphene materials adsorb odors and harmful gases;
Nanofiber filter layer: smaller pore size, lower pressure drop, and longer service life;
HEPA (H11~H13) grade filters have begun to be widely used.
The introduction of PTFE membrane filtration material makes it more suitable for extreme working conditions.
Representative products
Man FreciousPlus Series: PM2.5+ Antibacterial + Activated Carbon
Bosch Cabin Filter+ Series: Four-layer structure, effectively inhibits bacteria and adsorbs odors.
Frontier Exploration: Intelligent + Sustainable Materials (2023-2030)
