The working principle and internal analysis of air purifier.air purifier covid

　　Today, when the air quality is so bad, the most frequently mentioned term is PM2.5. The so-called PM2.5 refers to the particulate matter in the atmosphere with a diameter of less than or equal to 2.5 microns, sometimes called lung particulate matter. Although the content in the atmosphere is very small, it carries pathogens and harmful substances for a long time and has various transmission channels, which causes relatively great harm to the human body.

　　So you can see that more and more people on the street choose to wear masks for their health. However, when returning home or in the office, no one would be willing to continue to wear a mask to endure the sultry airflow. But the air quality in the home is not necessarily so good. If you open the windows, the air of poor quality outside will ventilate in; if you close the windows, the air in the home is quite stuffy. Therefore, more and more people choose to buy an air purifier for their homes, and they can enjoy fresh and healthy air after closing the windows.

　　Some people may wonder how a device can convert polluted air into fresh air? Our electrical appliances will introduce you: the wonderful magic of air purifiers.

　　First of all, air purifiers can be roughly divided into three categories: active, passive adsorption and filtration, a combination of active purification and passive purification.

　　Purification principles of active air purifiers: At present, the more mainstream air purifiers on the market are air purifiers based on other principles, which are quiet and have no consumables, and release beneficial negative ions.

　　The purification principle of passive air purifiers: What is more common in the market at present is that HEPA filters usually have a fan, which has a fast purification speed and many additional functions.

　　The combination of active purification and passive purification is referred to as the double purification type, which, as the name suggests, is a combination of the above two types of purification. Some high-quality purifiers also have additional formaldehyde purification, humidification and deodorization. In addition to photocatalyst technology, these functions are mostly provided with additional filters to achieve corresponding effects.

　　For example, our purifier: Taking the activated carbon layer can be used for deodorization as an example, the air purifier is an upgraded filter on the original HEPA filter, and a composite filter for smoke and odor removal, that is, through the addition of activated carbon and active oxidation The odor filter with three formulations of aluminum and cold catalyst achieves the function of adsorbing formaldehyde, TVOC, benzene and peculiar smell.
