How much do you know about how air purifiers work?

　　Find out what an air purifier does? First of all, we must find out the principle of the air purifier. Let's introduce the working principle of the air purifier!

　　The principle of air purifiers: According to the working principle of air purifiers, there are three main types: passive, active, active and passive. The purification technology of particles in the air mainly includes mechanical filtration, electret electrostatic filtration, high-voltage electrostatic dust removal, negative ions, plasma, etc.

　　There are four general mechanical filtration capture methods for mechanical filtration: direct interception, inertial collision, Brownian diffusion mechanism and screen effect. It has a good effect of capturing fine particles, but has large wind resistance, high purification efficiency, large filtration resistance, good filter sealing, short service life, and needs to be replaced regularly.

　　High-voltage electrostatic precipitator is a method that uses a high-voltage electrostatic field to ionize gas and make dust particles adsorb on electrodes. Although the wind resistance is small, the capture effect of large particles and fibers is not good. Cleaning is time-consuming, and it is easy to generate ozone, resulting in secondary pollution. High-voltage electrostatic precipitator is a method that not only ensures air volume but also adsorbs particles. In this method, high pressure is loaded before the particles pass through the filter element, so that the particles are charged, so that the particles are easily electrically adsorbed to the filter element.

　　Electrostatic electret filters can only effectively remove particles above 10 microns. When the particle diameter does not exceed 5 microns, 2 microns or even sub-microns, the mechanical filtration system will become more expensive and the wind resistance will increase significantly. Using electrostatic electret filter material for filtration, low energy consumption and high capture efficiency. At the same time, it also has the advantages of electrostatic dust removal and low wind resistance, but it does not require an external connection of tens of thousands of volts, so it will not generate ozone. Also, it is made of polypropylene for easy handling.

　　Electrostatic precipitator filters less dust, fumes and bacteria, preventing lung, lung, liver and other diseases. The most harmful to the human body is the dust smaller than 2.5 microns, because it can penetrate the cells and enter the blood. General cleaners use filter paper to filter the dust in the air, which is easy to block the filter holes. The dust not only cannot be sterilized, but also easily causes secondary pollution.
