High efficiency filter is mainly used to capture 0.5um of particulate dust and a variety of suspended matter. Ultrafine glass fiber paper is used as filter material, offset paper, aluminum film and other materials as partition plate, and the aluminum alloy is glued.

Each unit has been tested by the flame method, and has the characteristics of filtration efficiency, low resistance and large dust capacity. High efficiency air filter can be widely used in optical electronics, LCD liquid crystal manufacturing, biomedicine, precision instruments, beverage and food, PCB printing and other industries clean air conditioning end supply. High efficiency and ultra-high efficiency filters are used at the end of the clean room, and can be divided into: high efficiency filters with partitions, high efficiency filters without partitions, high efficiency filters with large air volume, ultra-high efficiency filters, etc.

In addition, there are three kinds of high efficiency filters, one is a super high efficiency filter, which can be purified 99.9995%. One is an antibacterial type high efficiency air filter without partition, which has an antibacterial effect and prevents bacteria from entering the clean workshop, and the other is a sub-high efficiency filter, which is cheap and previously used for purifying space with low requirements.
