How to choose the right HEPA filter?
1, high efficiency filter is mainly used to capture 0.3um below particulate dust and a variety of suspended matter. The ultrafine glass fiber paper is used as filter material, each of which has been tested by the sodium flame method. It has the characteristics of high filtration efficiency, low resistance and large dust holding capacity. The high efficiency filter includes the high efficiency filter with partition board and the high efficiency filter without partition board. The high efficiency filter with partition board includes: There are partition high efficiency air filter, high temperature resistant high efficiency filter, high humidity resistant high efficiency filter, no partition high efficiency filter including combined combined high efficiency filter, no partition high efficiency filter, liquid tank no partition high efficiency filter, ultra-low resistance no partition high efficiency filter, knife rack type no partition high efficiency filter, super high efficiency filter 0.1um filtration efficiency.

2, high efficiency filter is at the end of the air supply, the design and selection of high efficiency filter, should be selected from low to high, can protect the service life of all levels of filter. For example: G class filtration →F class filtration →H class filtration →U class filtration.
3, high efficiency filter commonly used frame are: wood frame, catalpa frame, aluminum frame, stainless steel frame. The material selection of HEPA filter outer frame directly affects the price of HEPA filter. Under the same conditions, the quotation of different outer frame HEPA filter is not the same.

4, such as in the high temperature sterilization production of clean equipment or oven, need to choose high temperature resistant high efficiency filter. Glass fiber filter material, high temperature resistant special rubber gasket, high temperature resistant, instant maximum temperature can reach 300 degrees. Of course, the price cost of high temperature high efficiency air filter is not the same as that of ordinary high efficiency filter, because it depends on the glue.

5. high efficiency filters that need to be used in high humidity and temperature environments, filter paper with high temperature and humidity resistance, partition board and frame materials must be selected to meet the requirements of production. Biological clean room and medical clean room, must choose the filter of metal frame body, and its surface should not be easy to rust, do not allow the use of wood frame plate filter, in order to prevent bacteria, affect the qualified rate of products.
