From the perspective of the working principle of air purifiers, there are mainly three types: passive, active,mini air purifier and hybrid active and passive. According to the air purifier technology for removing particulate matter in the air,mini air purifier there are mainly mechanical filter type, electrostatic electret filter type, high-voltage electrostatic dust collection,mini air purifier negative ion and plasma method. Mechanical filtration generally uses the following four methods to capture particles: direct interception, inertial collision, Brownian diffusion mechanism,mini air purifier and screening effect. It has a good collection effect on fine particles but large wind resistance. In order to obtain high purification efficiency,mini air purifier the resistance of the filter is relatively large. , And the filter needs to be dense, resulting in a reduced life span,mini air purifier and needs to be replaced regularly.
High-voltage electrostatic dust collection uses a high-voltage electrostatic field to ionize the gas so that the dust particles are charged and adsorbed on the electrode. Although the wind resistance is small,mini air purifier the effect of trapping larger particles and fibers is poor, causing discharge,mini air purifier and cleaning is troublesome and time-consuming. It is easy to produce ozone and form secondary pollution.
"High-voltage electrostatic dust collection" is a method that not only ensures air volume but also absorbs fine particles. This is a way to charge the particles by applying a high voltage before passing through the filter element,mini air purifier so that the particles are "easy to be adsorbed" to the filter element under the action of electricity.
The high-voltage dust collecting part originally applied high voltage to the two electrodes,mini air purifier and charged the passing dust when the two electrodes were discharged. Most dust is originally neutral or has a weak charge. Therefore,mini air purifier the filter element can only filter out dust that is larger than the mesh. But shrinking the mesh of the filter element will cause blockage. The high-voltage electrostatic dust collection method can charge the dust. Under the action of electricity,mini air purifier it is adsorbed on the specially processed and permanently charged filter element. Therefore,mini air purifier even if the mesh of the filter element is too large (coarse),mini air purifier it can surely capture the dust.
