What is the purpose of buying an air purifier?Air purifier sales

　　With the development of society, there are more and more platforms for everyone to learn knowledge, and the solutions to problems are getting better and better, but many times life also shows that good flowers do not often come, and good things do not often come to sharpen us. , air pollution is a good example. Of course, many people have begun to use their wisdom and found that many plants can purify a small amount of air, but more often you have to install a reliable air purifier at home to give yourself a Peace of mind. And what is the original intention of buying an air purifier? Nothing more than to solve the following problems.

　　1. Remove PM2.5 and other particles in the air

　　PM2.5 has long been a word most familiar to the Chinese people, thanks to which it has driven the vigorous development of the entire air purification industry.

　　The HEPA filter in the air purifier is interwoven with very fine organic fibers, which has a strong ability to capture particles, a small pore size, a large adsorption capacity, high purification efficiency, and water absorption. The purification rate for particles of 0.3 microns reached 99.97%. Its effect of filtering particulate matter is very obvious, so it is widely used in the manufacture of air purifiers.

　　2. Remove decoration pollutants such as formaldehyde after decoration

　　There are many technologies that claim to be able to remove formaldehyde on different air purifiers, such as activated carbon filters, photocatalyst coatings, ultraviolet rays, etc.... But the most effective of them is activated carbon.

　　It should be reminded that the adsorption capacity of activated carbon will decrease over time, resulting in the problem of "adsorption saturation". In theory, it should be replaced every half a month. If it is used to remove formaldehyde left after decoration, it means that you have to replace the air purifier filter frequently, which is very expensive. So in addition to air purifiers, you'd better prepare some more activated carbon bags at home to be more reliable.

　　Another formaldehyde removal technology that is popular in air purifiers is "photocatalyst coating", which can catalyze the degradation of harmful gases in the air under the action of ultraviolet light. However, this method requires the harmful substances in the air to contact with its surface to react, and the air purifier needs to have enough power to drive the air flow to improve the probability of the reaction.

　　3. Remove allergens such as pollen and pet hair

　　Pet hair and pollen are large particulate matter with a diameter of 10-100 microns, which is more than 4-40 times larger than PM2.5, and can be removed by most air purifiers. What we need to worry about is whether the filtration efficiency of this filter is high or not.

　　Of course, in addition to these main pollutants, there are many small pollutants in life, but the harm caused to the human body can be ignored, and the function of the air purifier also happens to solve these problems, so I will not list them one by one here. . As the saying goes, what a wise person fears most is the fear of being mistaken by wisdom. When dealing with indoor air pollution, opportunistic methods are just making excuses for their irresponsibility, so choosing an air purifier is a correct and reasonable solution.
