Air purifier cleaning steps

　　A good air purifier can effectively remove particles such as dust and pet dandruff that we cannot see with the naked eye, as well as formaldehyde, benzene, second-hand smoke and other harmful gases in the air, as well as bacteria, viruses and other microorganisms in the air. The negative ion air purifier can also actively release negative ions to promote human metabolism and benefit health. It can effectively remove large particles of dust, mold and animal hair, as well as other filter protection.

　　1. An important part of an air purifier is the filter layer. Air purifiers produced by air purifier manufacturers usually have three or four layers. The first layer is a pre-filter. The materials used by the brands of this layer are different, but their functions are the same, mainly to remove dust with larger particles. The second is the high-efficiency HEPA filter. This layer of filter mainly filters allergens in the air, such as mite debris, pollen, etc., and filters inhalable particles with a diameter of 0.3-20 microns. This filter layer filters out the PM2.5 particles that consumers are generally concerned about. The service life of this layer of filter is generally several years. After prolonged use, the filter can collect dust and particles, which are likely to be blown into the air again with the air.

　　2. The air purifier manufacturer states that the dust filter or dust collection plate of the air purifier should be cleaned frequently, usually once a week. Keep air circulation hygienic after washing and drying with soapy liquid or foam or board. There is a lot of dust on the fan and electricity, which needs to be cleaned, and generally maintained every six months. The dust on each electric and fan blades can be removed with a brush. Clean the air quality sensor every two months to ensure the purifier is working well. If the filter is used in a dusty environment, it should be cleaned frequently.

　　3. Air purifier manufacturers say that when indoor humidity is high, air quality sensors can create condensation. So, even if the air quality is good, the air quality indicator may just be poor air quality. In this case, you must clean the air quality sensor, or use any manual speed setting. Use a soft brush to clean the air inlet/outlet of the air quality sensor, remove the air quality sensor protective cover, clean the air quality meter, air inlet and air outlet with a slightly damp cotton swab, and dry it with a dry cotton swab , then install the protective cover of the air quality sensor, then dry it with a slightly wet cotton swab, then install the protective cover of the air quality sensor, then install the protective cover of the air quality sensor, and then install the air quality sensor cover, then put the air quality sensor cover, then put the air quality sensor cover, then put the air quality sensor cover, then put the air quality sensor cover , usually pay attention to moisture-proof, to avoid moisture affecting the use efficiency or damage.
