What technology does a good air purifier need?Air purifier Merchant

　　1. Electrostatic dust removal and sterilization technology

　　1) Electrostatic dust removal: It can filter dust, smoke and bacteria smaller than cells to prevent lung disease, lung cancer, liver cancer and other diseases.

　　The most harmful to the human body in the air is dust less than 2.5 microns, because it can penetrate cells and enter the blood. Ordinary purifiers use filter paper to filter the dust in the air, which is very easy to block the filter holes, and the more dust accumulates, not only has no sterilization effect, but also easily causes secondary pollution.

　　2) Electrostatic sterilization: The electrostatic tungsten wire releases 6000 volts high-voltage static electricity, which can instantly and completely kill bacteria and viruses attached to the dust, and prevent colds, infectious diseases and other diseases. The sterilization mechanism is to destroy the four polypeptide chains of the bacterial capsid protein and damage the RNA.

　　2. HEPA filter technology

　　HEPA is the abbreviation of HighEfficiencyParticulateAirFilter (High Efficiency Particulate Air Filter). The HEPA filter is composed of a stack of sub-glass fiber membranes that are continuously folded back and forth, forming a wave-shaped gasket to place and support the filter boundary.

　　3. Ion wind technology

　　Ion wind air purifier technology also uses more technology, but its purification efficiency remains to be verified. The ion wind air purifier is designed to adsorb particles on the charged metal blades in the purifier. The blades push the air through the components to form an air flow. The negative ions and positive ions attract each other, and the particles and smoke in the air are attached to the blades.

　　4. Negative ions

　　Negative ions are negatively charged gas ions in the air. Most of the free electrons generated by the ionization of air molecules under the action of high pressure or strong rays are obtained by oxygen. Therefore, air anions are often collectively referred to as "negative oxygen ions". . The molecular formula of anion is O2-(H2O)n, or OH-(H2O)n, or CO4-(H2O)n. The air anions with environmental protection functions mentioned here mainly refer to the first two small molecule anions.

　　5. Activated carbon

　　Activated carbon is a kind of very small carbon particles with a large surface area, rich micropores, and strong adsorption capacity. Because of the large surface area of carbon particles, they can fully contact with gas (impurities). When these gases (impurities) are adsorbed by the micropores, they play a purifying role.
