(1) installation of high efficiency filter:

As a result of the brittleness of glass fiber paper, so in the use and installation should first consider not to contact sharp objects and repeated rubbing, secondly, glass fiber paper should be used in contact with water or other corrosive liquid as far as possible, so as not to affect its normal use. Clean plant must have good cleaning equipment. Thirdly, the reasonable use of coarse, medium and high efficiency filter ensures that each filter does not bear heavy dust load. Visual inspection shall be carried out before installation to check whether the appearance of filter paper and filter is damaged, and the sealing condition shall be tested after installation to strictly detect leakage.

(2) common sense of high efficiency filter

For different particle sizes, the efficiency of the hepa filter can be up to 99.999999 (overseas). Some people equate the efficiency of a filter with the cleanliness of a clean room, and it seems like a hundred or even a ten can be achieved with as many as nine ultra-high performance filters. This is actually a misconception. Hepa filters are the heart of the system, but they are not the only guarantee of cleanliness. The efficiency of the hepa filter is only one of the necessary conditions, and it is also an easy condition to achieve. There are many other requirements to achieve a clean room grade, such as wind speed, air change times, door and window seals, and control of people entering and leaving the clean room. Only when all these aspects are up to standard can we guarantee the cleanliness of clean room.
