What is the difference between hepa filters H13 and H14?
What is the difference between hepa filters H13 and H14?In industrial clean rooms, there are many types of air filters used, which can be divided into primary, medium, and high-efficiency air filters according to their different uses. In these filters, only the high-efficiency filter can filter a large number of small air pollutants, so it is widely used in the air conditioning end of the dust-free purification workshop, as well as in biomedicine, precision instruments, beverages and food, optical electronics, LCD liquid crystal manufacturing, PCB printing and other industries.As the end filter of various filtration systems, HEPA filters are mainly used to capture particulate dust below 0.5um and various suspended solids. It has low resistance, large dust capacity, and high filtration efficiency. High-efficiency filters can be divided into H10, H11, H12, H13, and H14 according to efficiency levels. Among them, H13 and H14 grade filters are widely used. So what's the difference between H13 and H14? This article summarizes the difference between high-efficiency filters H13 and H14, hoping to help select the right high-efficiency filter. The difference between HEPA filters H13 and H14 is mainly reflected in the partition, filtration efficiency, and application range: 1. The H13 high-efficiency filter uses a separator design, while the H14 level uses different types of design, such as no separator, combined, liquid tank, disposable integration, replaceable integration, and high-humidity-resistant high-efficiency filters. 2. H13 and H14 are two different levels of HEPA filters. The H13 filter can effectively filter air particles above 0.3 microns, with a filtration efficiency of more than 99.99%. The H14 level filter further improves the filtration efficiency and can filter air particles above 0.3 microns, with a filtration efficiency of more than 99.995%. Therefore, from the point of view of filtration efficiency, the HEPA filter of grade H14 is superior to the filter of grade H13. 3. There are also differences in the scope of application of HEPA filters of H13 and H14 levels. H13-grade filters are commonly used in general air filtration fields such as homes, offices, medical facilities, etc. It can effectively remove dust, pollen, mold spores, and other small particles in the air, providing people with a clean and healthy environment. The H14 level HEPA filter is more suitable for places with higher cleanliness requirements, such as laboratories, operating rooms, pharmaceutical factories, etc. Due to their higher filtration efficiency, H14 filters can effectively remove smaller particles, so they are more common in environments with higher air quality requirements. The H14 level filter is also widely used in some special occasions, such as nuclear facilities, biosafety laboratories, etc., because it can effectively filter microbial particles such as bacteria and viruses in the air to ensure the life safety of personnel. The above is the main difference between HEPA filters H13 and H14, the H14 level filter has higher filtration efficiency, and a wider range of applications, and is more common in places with higher air quality requirements. The H13 filter is suitable for general air filtration. Choosing the right HEPA filter depends on the characteristics and needs of the environment. Zhongjing Purification specializes in the production of high-efficiency filters and has rich production experience and excellent manufacturing technology, the production of high-efficiency filters to galvanized plate, stainless steel plate, and aluminum alloy profile as the outer frame, and each set is tested by the flame method, Suitable for electronics, semiconductors, precision machinery, biopharmaceuticals, hospitals, food, and other industries in the air cleanliness requirements of high civil or industrial cleaning projects. |
