air purifiers are common in Zhengzhou building materials and furniture market, and the maintenance of air purifiers in Zhengzhou has started relatively, but is the air purifier as useful as the merchants say? Let Xiaobian help you answer whether the air purifier is useful. Air purifiers are also called "air cleaners" and air fresheners. Air purifiers refer to products that can adsorb, decompose or transform various air pollutants such as dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc. Air purifiers can effectively improve air cleanliness. At present, domestic and commercial air purifiers are mainly used to remove indoor air pollution. The function of the air purifier needs no modification. The most important thing is that consumers can get a healthy environment. Is the air purifier useful? The function of air purifier is to remove particulate matter: dust, yellow sand, dander and pollen are the causes of allergic diseases, eye diseases and skin diseases. Chemicals: harmful chemicals such as formaldehyde, benzene, ammonia, sulfur and carbon monoxide are the main causes of cancer, and air purifiers can effectively remove chemicals. Air purifiers can be harmful to bacteria: influenza virus, mold, and air conditioners contain bacteria that cause high fever, diarrhea, pneumonia and other diseases. Air purifiers can remove microorganisms: mites affect people's skin health. Harmful fungi such as aphids cause respiratory diseases. The air purifier can remove odor: it can remove the odor of human body, life, industry, chemistry, pets and so on. Harmful exhaust gas: vehicles, industry and cigarettes are the main causes of headaches, soreness and dizziness. Is the air purifier useful? The maintenance of air purifiers depends on different brands and types of air purifiers. The composition of air purifiers is similar, so the maintenance method is relatively simple: the pre-filter screen will gather some dust for a long time, which will affect the intake air and the effect of air purification. Need to use a vacuum cleaner to remove the dust, or use a rag to clean it, or even wash it with water. Ion generators are generally built-in and do not need to be cleaned. Better ion generators have higher working efficiency. Deodorizing filter screen, the deodorizing filter screen of a few brands of air purifiers, can reach the technical level of washability, which can maintain the purification efficiency and prolong the cycle of changing the filter screen by washing. Filters, some of which need to be taken to the sun regularly to bask in the sun, can better maintain the purification efficiency, such as activated carbon filters. Is the air purifier useful? Let's first understand the composition of the air purifier. The air purifier mainly consists of: case shell, filter section, air duct design, motor, power supply, LCD screen, etc. It is the motor that determines the life of the air purifier, the filter section that determines the purification efficiency, and the air duct design, chassis shell, filter section and motor that determine whether it is quiet. No matter which part of the air purifier has problems, there is no guarantee that the air purifier will play a good role. Is the air purifier useful? The air purifier can effectively remove bacteria, chemicals and other substances harmful to the human body. Of course, he should be very careful about the maintenance of the air purifier.
