Product characteristics of HEPA filters:
1. HEPA stands for High Efficiency Air Filter in Chinese. A filter that meets HEPA standards has an effectiveness rate of 99.7% for 0.1 microns and 0.3 microns,The characteristic of a composite HEPA filter is that air can pass through, but small particles cannot pass through.

It can achieve a removal efficiency of over 99.97% for particles with a diameter of 0.3 microns (1/200 of a hair diameter) or more, making it an effective filter medium for pollutants such as smoke, dust, and bacteria.

HEPA filters are made of five materials: PP filter paper, glass fiber, composite PP PET filter paper, melt blown polyester non-woven fabric, and melt blown glass fiber. Features: Low wind resistance, large dust holding capacity, high filtration accuracy, can be processed into various sizes and shapes according to customer needs, suitable for different machine models.

2. Filtration efficiency: The efficiency varies depending on the material, as shown in the table below.
3. Select and design materials based on the air volume requirements, installation size requirements, filtration efficiency, and resistance requirements of the equipment;
4. According to the customer's target price and performance requirements, imported or domestically produced materials can be selected for production.

The main applications of HEPA filters are:

HEPA high-efficiency filter can be widely used in the air conditioning end air supply of dust-free purification workshops in industries such as optical electronics, LCD manufacturing, biomedicine, precision instruments, beverages and food, PCB printing, etc. Both high-efficiency and ultra HEPA high-efficiency filters are used at the end of clean rooms, and can be divided into three types based on their structural forms: high-efficiency with partitions, high-efficiency without partitions, high-efficiency with high air volume, and ultra HEPA high-efficiency filters.

In addition, there are three types of composite HEPA filters, one of which is a super HEPA high-efficiency filter that can purify 99.9995%. There are two types of high-efficiency air filters: one is an antibacterial type without partitions, which has antibacterial effects and prevents bacteria from entering the clean room. The other is a sub HEPA high-efficiency filter, which was previously used in low demand purification spaces due to its low price.

2. Various household and commercial air purifiers, fresh air fans, air conditioners, electronic industry, medical equipment, etc.
