Air purifier filter technology introduction.Car Air purifier Factory

　　High efficiency particulate air filter (HEPA) is one of the most popular technologies used in air purification. The standard HEPA filter can absorb 99.7% of the suspended particles with a size of 0.3 microns (0.3 microns is the size that Z is difficult to filter), but its wind resistance is relatively large, and it is rarely used in air purifiers. Actual air purifiers The HEPA declared by the manufacturer is actually not the real HEPA. Its filtration efficiency is slightly lower than that of HEPA, and the wind resistance is relatively low. Whether it is the real HEPA or the publicized HEPA, it makes the inhaled air fresher and cleaner. The filter absorbs chemical fumes, bacteria, dust particles and pollen. After being filtered by the air purifier, there are no such pollutants in the air.

　　The advantage of the HEPA filter is that it is effective and safe. It is the main technology for removing particulate pollutants in the air, but the disadvantage is that it can only filter out suspended particles and cannot filter out harmful gases. Air fresheners using HEPA must have a good airtight design, otherwise the air will go around the filter and lose the filtering effect.

　　Electrostatic electret filter technology

　　The use of non-woven fabrics loaded with electrostatic electrets to collect dust is an upgraded version of HEPA technology. The advantages are low wind resistance, high efficiency, high dust holding capacity, Z is mainly safe. Represented by the “high-efficiency electrostatic air filter” on the market, the breakthrough filter material that carries permanent static electricity is used to effectively block particulate pollutants larger than 0.1 microns in the air, such as dust, dander, pollen, bacteria, etc., at the same time. Impedance ensures energy saving. In addition, the deep dust-holding design ensures a longer service life. As of 2013, it has been widely used in home and car (such as SAIC, Volkswagen, GM and other well-known brand-selling models) air-conditioning and some commercial construction areas (such as the Bird's Nest, Beijing Hotel, Capital Airport Phase III).
