[PConline Professional Review] With the arrival of hot weather in the summer, the air quality has once again received attention. In recent days, there have been many cases of "disease runways," leading to nosebleeds, nasal itching, stomach pain, and coughing. Exposure to hot weather or ultraviolet radiation will accelerate the release of harmful gases, causing harm to the human body. Furniture at home may also be the source of pollution, and at high temperatures it will accelerate the volatilization of harmful substances such as formaldehyde.
In the summer, air pollution is not only polluting. When we stay in air-conditioned houses with closed air for a long period of time, we avoid the heat of summer heat and enjoy the coolness brought by air-conditioning. However, it is easy to suffer from air-conditioning diseases because the air is not circulating and bacteria are easy to grow. While people enjoy the comfortable temperature in the room, air purification must not be taken lightly. In fact, it is easier for the monks to get sick in the air-conditioned room. This is because the space is relatively closed, the air does not circulate, pathogenic microorganisms are easy to breed, and the temperature difference between the interior and exterior is large, and the body is not well-adapted. These bacteria include Escherichia coli, Staphylococcus aureus, Staphylococcus aureus, airborne natural bacteria, etc. Some are important pathogenic factors, so removal by more effective methods is necessary.
The air purifiers on the market can only remove pollutants of PM2.5 or formaldehyde and cannot effectively eliminate bacteria in the air. Human normal breathing will inhale these bacteria into the body, causing the emergence of virus infection and other conditions, ordinary air purifiers can not effectively eliminate the bacteria, and Matsushita Electric is to look at this point, introduced in other industry air disinfection machine, it In addition to purifying PM2.5 and efficiently removing formaldehyde, it also eliminates harmful bacteria in the air. The Guangzhou Industrial Microbiological Testing Center has found that the air disinfection performance of its simulated field test is greater than 99.99%, and the field test air disinfection performance is as high as 99.90%.
For the summer, the harmful effects of formaldehyde are less inevitable because summer temperatures are higher, which can cause paint and other substances on furniture to work and emit harmful substances such as formaldehyde and TVOC. The Panasonic air disinfection machine is equipped with a special addition of formaldehyde filter and deodorizing filter, which not only can achieve high efficiency of formaldehyde removal and adsorption, but also can effectively remove the odor. According to the test report of the testing center, its formaldehyde CADR value is as high as 92.1m3/h, and the formaldehyde purification energy efficiency class has reached a high efficiency level.
Panasonic introduced this air disinfection machine, Xiao Bian at the beginning of the AWE (China Household Appliances Expo) has seen. Compared with ordinary air purifiers, it is equipped with a 6-pump purifier system, which realizes a combination of sterilizing mode and PM2.5 rapid purging mode. Provides users with intelligent 4-fold sensing technology, more intuitive PM2.5 value and humidity display. It is worth mentioning that the Panasonic factory obtained the hygiene certificate of the production enterprise: Yuewei Decontamination Word [2015] No. 1269. The hygienic safety assessment report of the disinfection product has been filed according to law. What is the effect of this air disinfection machine? We will conduct a comprehensive evaluation.
