Is the filter of the central air-conditioning air purification device as many as possible

Many people will ask: Is the filter screen of the central air-conditioning air purification device as many layers as possible? the answer is negative. The filter of the central air conditioner air purifier is not based on the number of layers, but on the filtering technology.

The more layers of the central air-conditioning air purifier filter, the better the filtering effect. This concept is incorrect. The people who put forward this concept are generally customers in the air purifier industry. In order to highlight the advantages of their products, they are included in the advertising There are several types of filters listed, and several layers of filters have their own different functions, and some are even superimposed on 8 layers.

　　 The more layers the better, it is purely a slogan.

In fact, there is only one kind of the best central air-conditioning air purifier filter on the market, that is, the Weiyi plasma high-voltage electrostatic precipitator, which can filter dust in the air, particles above PM10, hair and other large particles; filter the air The oil fume, formaldehyde, odor, bacteria, TVOC and other toxic and harmful substances in the air; the filter filters the PM2.5 and below in the air or other particles, bacteria, and germs that can be inhaled into the lungs.

The quality of the central air-conditioning air purifier filter is mainly determined by the level of the filter. The higher the level, the higher the purification rate. Weiyi Plasma Static Point Dust Collector is medical grade purification, generally used in sterile operating rooms or aviation Research in the aerospace industry can purify more than 99.9% of PM2.5, 99% of bacteria and viruses and more than 97% of formaldehyde in the air.

　　The quality of the central air-conditioning air purifier filter is not determined by the number of layers. The superposition of the filter can not bring cleaner air than the plasma electrostatic precipitator, which is pure waste.
