As we all know, the filtration efficiency level of high-efficiency filters can reach more than 99.999995 for different pollution particle sizes. H13-level high-efficiency filter material is the filter core filter material. However, in the past, some people always associated the clean room level with the efficiency level of high-efficiency filters. They always felt that the more 9-level high-efficiency filters used, the clean room could reach level 100 or even level 10 cleanliness.
In fact, this concept is wrong. Although the high-efficiency filter is the core component of the clean room, the clean room wants to To reach level 100 or even level 10 cleanliness, high-efficiency filters are not a condition. There are many factors that affect the cleanliness level of a clean room, such as the number of air changes, the sealing degree of doors and windows, and personnel entering and exiting the air shower room. Only by strictly controlling these factors can we ensure the cleanliness level of the clean room.
Due to the different characteristics of clean rooms, the selection of high-efficiency filters needs to be based on the level, sterility, temperature and humidity, fire resistance, anti-corrosion, etc. of the clean room. Requirements to determine the selection of H13 grade high-efficiency filter material.
If the filter is below 100, choose type A or type B, and above 100, you need to choose type C filter; under high temperature and high humidity conditions, metal partitions should be used. Filters with plates and metal frames; filters with plastic partition plates and plastic frames should be used if there are anti-corrosion requirements; if there are fire protection requirements, all materials of the filter should be non-combustible, etc.
In practice, conventional filters refer to Class A and Class B specified in the high-efficiency air filter standards. They are commonly used high-efficiency filters in clean factory design. Generally, if the level is less than or equal to 100,000, you can choose Category A; if the level is 10,000 to 100, you can choose Category B. For conventional high-efficiency filters, the efficiency for particles ≥0.5μm can be calculated based on five “9s”, which is 0.9999.
High-efficiency filters are mainly used to filter airborne particles below 0.3um, as the terminal filtration of various filtration systems; as for 300,000-level, 10,000-level, The selection and configuration of air filters in clean areas of Class 1,000 and Class 100 clean rooms. Generally speaking, the selection of filters is based on the clean room grade requirements.
As a high-efficiency separation filter material design solution provider, we are committed to developing and manufacturing high-quality H13 grade high-efficiency filter materials and Composites to protect people, processes and systems. And for clean room applications, we have specially developed clean room high-efficiency air filter materials – H13 grade high-efficiency filter materials, which can be used as the core filter material of clean room high-efficiency air filters and have H13-U16 levels. It has reliable filtration level, low wind resistance and low energy consumption, and is widely used in semiconductor, electronics, flat panel display, photovoltaic and other industries.
