Air purifier: A general household air purifier is mainly composed of motors, fans, air filters and other systems. Its working principle is: the motor and fan in the machine make the indoor air Circular flow, the polluted air passes through the air filter in the machine to remove or adsorb various pollutants. Some models of air purifiers will also be equipped with an anion generator at the air outlet (the high-pressure in the anion generator during operation Generates DC negative high voltage), continuously ionizes the air, generates a large number of negative ions, and is sent out by the micro fan to form a negative ion airflow to achieve the purpose of cleaning and purifying the air. The filter plays a purifying role in the purifier, and the production of this product is inseparable from HEPA high-efficiency filter paper.
HEPA filters are divided into specifications according to the level of filtration capacity. They are generally divided into various grades such as G1 to H14. According to the diameter For fine particles above 0.3 microns, G1-F5 has no filtration effect, and the filtration efficiency of F6-H14 ranges from 20% to 99.999997%. Among them, F6-F8 are called medium-high-efficiency air filters; F9-H11 are called sub-high-efficiency filters; H12-H13 are called high-efficiency air filters. H14 is called a super high efficiency air filter.
The HEPA filter is made of interwoven fine organic fibers. It purifies the air by adsorbing fine particles in the air. High-grade HEPA filters can even be highly efficient. It adsorbs and filters particles with a diameter less than 0.3 to purify the air.
HEPA high-efficiency filter paper is the core filter material of the air purifier. This material is made of ptfe film and non-woven fabric. HEPA high-efficiency filter paper has reliable filtration levels of H13-U16, low wind resistance, low energy consumption, ULPA, HEPA and other levels of filtration, excellent chemical resistance, and is widely used in clean rooms, Electronics, photovoltaics, FFU and many other fields.
