HEPA (High Efficiency Particulate Air) air filter paper is a high-filtration material that is widely used in air purifiers, vacuum cleaners and other air treatment equipment. Its main function is to capture tiny particles in the air, such as dust, pollen, small bacteria, viruses and other pollutants.
Here are some features and working principles of HEPA air filter paper:
1. Filtration efficiency: The filtration efficiency of HEPA air filter paper is very high, usually reaching 99.97%. This means it is capable of filtering out particles up to 0.3 microns in size, including both larger and smaller particles.
2. Multilayer structure: Usually composed of multiple layers of fiber materials, these fibers are tightly arranged to form a network structure. This structure allows the filter paper to capture particles well and prevent them from passing through the filter.
3. Mechanical filtration: Adopt the principle of mechanical filtration. When the air passes through the filter paper, the particles are trapped in the fiber gaps of the filter paper due to mechanisms such as inertia, diffusion, and interception, thereby achieving high filtration.
4. Widely used: HEPA laboratories, food processing plants, etc. They are also commonly used in special environments such as hospital operating rooms and laboratories to provide clean air.
It should be noted that HEPA air filter paper needs to be replaced regularly to ensure its high filtration effect. The specific replacement cycle depends on the use environment and equipment requirements. It is recommended that maintenance and replacement be performed in accordance with the manufacturer’s guidance and recommendations. Interested parties are welcome to enter the store and contact us.
