The epidemic has significantly increased people's awareness and demand for healthy home appliances, and air purifiers have gradually become one of the standard home appliances in many families. In particular, the Bao parents and mothers are very concerned about the indoor air quality. Although it is the safest to stay at home, the indoor air is relatively dirty when they gather at home for a long time, which can easily cause the breeding of indoor bacteria and viruses. To effectively prevent influenza viruses and other bacteria from harming themselves and their families, many families choose to buy air purifiers to keep the indoor environment fresh and protect the respiratory health of the whole family.
At present, most of the air purifiers on the market are physical filtration, that is, the air is filtered through a built-in filter. As long as the pore size of the filter is smaller than the diameter of the microorganism, the pollution source can be filtered out. The most commonly used is the HEPA filter, which is made of very fine organic fibers. It has a strong ability to capture particles, a small pore size, a large adsorption capacity, a high purification efficiency, and it has water absorption. It is targeted at 0.3 micron particles. The rate is 99.97%.
Of course, experts also pointed out that the diameter of the new coronavirus is about 0.06~0.14 microns. It can and must be transmitted through saliva, dust and other carriers. The carrier of communication is larger than 5 microns. At this time, masks are like air purifiers worn on our mouths and noses, blocking these viral vectors before the viral air enters our bodies. And a qualified air purifier can easily filter the polluted air in the home, leaving only pure air to ensure our safety and health.
In addition, odor removal is also the most important assessment standard for air purifiers. Here we need to mention photocatalyst air purifiers. Photocatalyst is a new type of deodorizing and purifying air material. Photocatalyst is currently the safest and cleanest environmental purification material in the world. It is widely used in Europe, America, Japan, South Korea and other regions. The United States Aerospace Station purification project, offshore oil pollution degradation project and The disinfection projects of Japanese bus companies all use photocatalysts to treat forest dances. Photocatalysts can effectively degrade formaldehyde, benzene, toluene, xylene Xylene, ammonia, TVOC and other pollutants, and have a highly efficient and extensive Disinfection performance. Performance, can decompose and harmlessly treat the toxins released by bacteria or fungi. Non-toxic, harmless, safe and reliable to the human body without secondary pollution.
Finally, when purchasing an air purifier, you must understand the working principle of the machine, in order to better grasp the functions of the product and choose products that are more suitable for your needs. At present, the purification of air purifiers can be roughly divided into three categories according to their principles. Some are better for removing formaldehyde, some are good for deodorizing, some cannot be humidified, and some can be used with humidifiers, so there is no all-round air purifier. Each brand has its limitations, so when choosing an air purifier, you still need to choose according to your home needs. Of course, as an air purifier is a household appliance used daily, noise is also a problem that cannot be ignored. In addition, its purification energy efficiency and time are also aspects that need to be considered. Of course, relatively speaking, the quality, service life, and after-sales service of air purifiers produced by well-known brands will be more guaranteed.
