Which is better for the air purifier?
Classified according to air purifiers for particulate removal techniques in the air:
1, mechanical filtration: Usually primarily to capture the particulates in the following four ways: direct interception, inertial impaction, Brownian diffusion mechanism, the screening effect, which is good but the drag large to fine particles collected and, in order to obtain a high purification efficiency, the filter resistance Larger, and the filter needs to be dense, resulting in reduced life and need to be replaced regularly.
2 , high-voltage electrostatic dust collection: the use of high-voltage electrostatic field to ionize the gas to make the dust particles charged to the electrode dust collection method, although the wind resistance is small, but the large particle and fiber collection effect is poor, will cause discharge, and cleaning It is troublesome and time consuming, and it is easy to produce ozone and form secondary pollution. "High-voltage electrostatic dust collection" is a way to ensure both air volume and fine particles. This is the way by which the particles are charged by applying a high voltage before the particles pass through the filter core, so that the particles are "easy to adsorb" onto the filter element under the action of electricity.
3 , electrostatic electret filter: relative mechanical filtration can only effectively remove particles above 10 microns, and when the particle size of the particles is divided into 5 microns, 2 microns or even sub-micron range, efficient mechanical filtration The system becomes more expensive and the wind resistance increases significantly. Filtered by electrostatic electret air filter material, it can achieve high capture efficiency with low energy consumption, and has the advantages of electrostatic dust removal and low wind resistance. However, it does not need to connect tens of thousands of volts, so ozone will not be generated. Its composition is made of polypropylene, which is easy to dispose of.
4 , electrostatic dust removal: can filter dust, smoke and bacteria smaller than cells, to prevent lung diseases, lung cancer and other diseases. The most harmful to the human body in the air is dust less than 2.5 microns, which penetrates cells and enters the bloodstream. The ordinary purifier uses filter paper to filter the dust in the air, which is easy to block the filter hole. The dust not only has no sterilization effect, but also easily causes secondary pollution.
5 , electrostatic sterilization: the use of high-voltage electrostatic field of about 6000 volts, can instantly kill bacteria and viruses attached to the dust, to prevent colds, infectious diseases and other diseases. Its sterilization mechanism is to destroy the four polypeptide chains of the bacterial capsid protein and damage the RNA .
6, natural air purifier: The test demonstrated that the lamp is a natural gypsum crystals air purifier having a volatile anion, adsorbing impurities in the air, and other environmental harmful rays electrical shielding function. The singularity is that during the day, it shows a completely natural stone texture, simple, simple, heavy, exudes a strong natural atmosphere and a simple and mysterious style; at night, it becomes a magician who creates a warm atmosphere, pure white as jade The crystal gypsum ore, the light is soft and quiet; the orange crystal gypsum lamp, the red light that shines out becomes the master of the mood, lit up, and the romantic atmosphere is surrounded by the atmosphere.
