Air Filter Material Types Explained
The material of an air filter determines its filtration efficiency, service life, and suitable applications. Different types of filter media have unique advantages in dust removal, odor absorption, and antibacterial performance.
1. Primary Filter Media
1). Non-woven Fabric Filter
Made from polyester or polypropylene fibers, non-woven fabric features uniform texture and good breathability, effectively capturing large particles such as dust, pollen, and fibers.
2). Aluminum Mesh Filter/ Metal Mesh Filter
Made of aluminum or galvanized steel, this filter is durable, heat-resistant, and washable for multiple uses.
2. Medium Efficiency Filter Media
1). Synthetic Fiber Filter
Composed of multilayer synthetic polymer fibers, it offers stable filtration performance with low resistance and high dust-holding capacity.
2). Glass Fiber Filter
Made from ultra-fine glass fibers, it provides high filtration precision and excellent temperature and humidity resistance.
3. HEPA / ULPA Filter Media
1). Micro Glass Fiber Filter
The core material of HEPA filters, capable of capturing particles as small as 0.3 microns with 99.97% efficiency.
2). PTFE Membrane Filter
Features excellent chemical resistance and extremely low airflow resistance, ensuring ultra-high filtration efficiency.
4. Functional Filter Media
1). Activated Carbon Filter
Removes odors, formaldehyde, and harmful gases through physical adsorption and chemical reaction.
2). Photocatalyst Coating Filter
Decomposes organic pollutants and inhibits bacterial growth under UV light.
5. Eco-friendly Filter Media
With growing environmental awareness, more manufacturers are adopting recyclable and biodegradable materials such as PLA bio-fibers.
