As the name suggests, is the use of ionized air, so that the particles in the air charged, so that the electrode adsorption of air purification technology. Because of the process level requirements are not high, the cost is relatively low, so this technology is currently more widely used in the domestic "psychological comfort group" on the new air purifier. But the shortcomings are also fatal, that is, ozone. Learned high school physics know, ionized air will inevitably produce ozone. And ozone is one of the four typical air pollutants listed by the World Health Organization. Because it irritates the respiratory system, it also affects the human skin, nerves and immune system. Based on such an embarrassing reality, many western countries, including the United States, have banned air purifiers that use electrostatic adsorption as a single means of air purification from being used in occupied settings. Here to remind a word, a lot of chicken thief enterprise has smelled the breath of uncertainty, so now have closed their mouths do not mention electrostatic, adsorption, ozone and such sensitive words, and replaced with ionic wind, anion and so on a variety of vest.
Two, HEPA
HEPA is the abbreviation of High EfficiencyParticulate Air Filter, pronounced afraid, meaning high efficiency air particulate filter, is internationally recognized as the most efficient filtering materials, widely used in medical and surgical, high-precision experiments, aerospace and aviation, such as ultra-high requirements for cleanliness of the place. However, all professional new air conditioners use HEPA as the main filter material. Of course, the filtration effect of the new air conditioner and HEPA filter element production process and level has a direct relationship. Countries around the world have their own standards for HEPA grade, the most common is the European standard EN1822. The standard divides HEPA filter media into three grades, E grade, H grade and U grade. In the civilian field, H grade is usually used, of which two standards, H13 and H14, have achieved an efficiency of over 99.75 and 99.975 for MPPS, respectively. This MPPS stands for Most Penetratable Particulate Size, which is usually 0.1 or 0.3 microns. So you don't have to ask questions like "can a new air conditioner filter PM2.5" anymore. However, HEPA with H13 level, for example, requires a very high level of manufacturing process and is quite expensive. Therefore, the cheap brand air purifier even if the use of HEPA filter purification technology, it is simply not possible to choose such a high level.
Three, the Court Rui Pu new air machine 3M four-in-one + 3M European standard H13 level of high-efficiency HEPA
3M electrostatic air filter, can effectively avoid indoor air pollution
Classic high-efficiency filter, innovative scientific and technological materials, the filter medium with a permanent electric ions, the filter material to maintain a high-efficiency electrostatic dust removal filters, significantly improve the performance of the effective adsorption of small molecules of 0.1 microns.
Three-perimeter fiber structure, ultra-low resistance, does not affect the new air conditioner air volume, depth of dust holding characteristics, longer service life.
Antibacterial coating, does not contain chemical additives, effectively inhibit the growth of bacteria, fungi, etc., health is guaranteed.
Hope it helps you, hope to adopt
