High efficiency air filter is generally used as the filter end, so the requirements for high efficiency filters are also the most stringent. High efficiency filters are the most critical level of filter at all levels and require additional "viewing". The most fundamental way to extend the life of an efficient filter is to keep the dust in the prefilter. The replacement of pre-filtration usually does not need to be discontinued, without debugging, so experienced owners will put their attention and money on the prefilters. For the 10,000 and 100,000 clean plants. Prefiltration can be used with F8 filter, which can last up to five years. 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
