The non-woven filter, with its advantages such as high-efficiency filtration, compact structure, and low resistance, is widely used in scenarios with extremely high requirements for air cleanliness, mainly covering the following major fields:

1. Pharmaceutical and medical device industry
Aseptic production workshop: During the pharmaceutical manufacturing process, from raw material handling, formulation production, to packaging and other links, it is necessary to strictly control the microorganisms and dust particles in the air. The non-woven filter can provide clean air of Class 1-100, ensuring that the drugs meet the GMP (Good Manufacturing Practice) standards.
Biopharmaceutical laboratory: It is used in scenarios such as vaccine research and development and bioengineering experiments to prevent the diffusion of aerosols generated during experiments and to avoid the influence of external pollutants on experimental results.
Medical device cleaning and disinfection workshop: Purify the air in the cleaning and sterilization environment of surgical instruments and precision medical equipment to prevent secondary pollution.
2. Electronics and semiconductor industry
Chip manufacturing workshop: Chip production is extremely sensitive to particles in the air, especially those smaller than 0.1μm. Non-woven filters (such as H14 grade) can effectively filter out such particles, preventing them from adhering to the wafer surface and causing circuit defects.
Electronic component assembly workshop: During the assembly process of integrated circuits, sensors, and precision electronic components, it can reduce the impact of dust on product performance and improve the product qualification rate.
Photolithography room: The photolithography process is a core link in semiconductor manufacturing, and the air cleanliness requirement must reach Class 1. The non-woven filter is the key equipment to maintain this environment.
3. Medical and health care field
In hospital operating rooms, especially Class 100 and Class 1,000 clean operating rooms, it is necessary to achieve efficient air circulation and filtration through non-particulate filters to reduce the risk of infection at the surgical site and ensure patient safety.
ICU (Intensive Care Unit): It provides clean air for patients with weakened immunity, reduces the spread of pathogens in the air, and assists patients in their recovery.
Biosafety laboratory (P3/P4 level): A laboratory used for handling highly pathogenic microorganisms (such as viruses and bacteria), with non-woven filters that can filter out pathogens in the air to prevent leakage and biosafety incidents.
4. Food and beverage industry
Aseptic filling workshop: During the aseptic filling process of fruit juice, dairy products, beverages, etc., air is filtered to prevent microbial contamination and extend the shelf life of the products.
Health care product production workshops: For the production of products such as probiotics and nutritional supplements, it is necessary to control the air cleanliness to ensure the activity and purity of the products.
5. Aerospace and Precision Manufacturing
Aerospace components processing workshop: When processing and assembling precision components of satellites and rockets (such as gyroscopes and sensors), it is necessary to avoid precision errors caused by dust particles. The non-woven filter can provide a clean environment.
Precision instrument laboratory: such as the research and development and testing environment for optical instruments and laser equipment, reducing the interference of particles in the air on the accuracy of instruments and measurement results.
6. Research and laboratory fields
Clean laboratories: Laboratories in fields such as materials science, nanotechnology, and biochemistry in universities and research institutions require a stable and highly clean air environment to support experimental research.
Animal laboratory: The air in the breeding environment of experimental animals is purified to ensure both the health of the animals and the accuracy of the experimental data.
7. Other special scenarios
Data centers: Some high-precision server rooms have high requirements for air cleanliness. Filters without separators can reduce the impact of dust on server heat dissipation and lifespan.
Nuclear industry-related sites: In scenarios such as nuclear material processing and radiation protection, it is used to filter radioactive particles in the air to protect personnel and environmental safety.
In conclusion, the core application of the non-woven filter is to meet the demand for high cleanliness, especially suitable for places with limited space but strict requirements for filtration efficiency and energy consumption control.
