F8 filters are the most common prefilters in foreign projects and domestic new projects. For chip plant 100, level 10 or higher, the common efficiency level of prefilters is H10, and many new items are selected for HEPA. In the design of clean room air conditioning system in the past, the filter is commonly configured as: effective and efficient. At that time, the life of high efficiency filters was only 1--3 years, and the worst was months. Therefore, the efficiency of the prefilter determines the life span of the end-filter
