On average, people spend more than 80% of their time indoors every day, so indoor air quality is more closely related to human health. To improve indoor air quality, breathe fresh, clean air every day. In addition to not smoking indoors, cooking less and frying less frequently, and cleaning and dusting regularly, you need an air purifier.
The function of an air purifier is to remove harmful substances from the air, and the filter is the filter that directly completes this task, so the filter It is the core component of the entire purifier.
The first layer is a coarse filter layer, which is mainly used to filter relatively large pollutants such as hair and inhalable particles in the air. The second layer is the PM 2.5 filter layer. Currently, most of them use HEPA (High efficiency particulate air Filter), which means air filter in Chinese. With an efficiency of 99.7% for 0.1 microns and 0.3 microns, the HEPA mesh is characterized by the fact that air can pass through, but fine particles cannot. HEPA air filter paper is the core material inside. The third layer is the adsorption layer, and the mainstream material is activated carbon.
HEPA air filter paperThere are many kinds of materials, which can be divided into polypropylene filter paper, PET filter paper, PP and PTFE filter paper and glass fiber filter paper . Among them, PTFE filter paper has good performance. Compared with other filter materials, it can not only achieve a good balance between wind resistance and interception rate, but also can clean dust through mechanical vibration or wiping to achieve reuse.
The HEPA air filter paper obtained by thermally compounding the independently developed PTFE microporous film and imported non-woven fabric is the HEPA filter element Made of raw materials, it has a reliable filtration level of H13-U16, low wind resistance and low energy consumption, and can be widely used in semiconductor, electronics, flat panel display, photovoltaic and other industries.
