autumn and winter are the seasons with high incidence of haze. Especially in recent years, the problem of environmental pollution has become more and more serious, and the problem of haze has also been widely concerned. In the past two days, the haze from the north to the south, Shanghai, Jiangsu “ Fall ”. At 9 a.m. on December 15, the data of Shanghai Environmental Monitoring Center showed that the real-time air quality index reached 316, and the primary pollutant was PM2.5. The air quality index in the past 24 hours was 254, which was heavy pollution. So when the haze strikes, what kind of products should we choose and how to correctly realize self-protection

how to correctly understand haze

in fact, haze weather has a long history, but in recent years, due to the accumulation of environmental problems, haze problems have also begun to occur frequently, and PM2.5 explosion may even occur in many regions. Haze in the North mainly comes from the exhaust gas from heating and coal burning, which is actually caused by “ Fog ” And “ Haze ” PM2.5, a combination of two words, is a particle with an aerodynamic equivalent diameter of less than 2.5 microns in the environment, and it is also an important indicator to measure air quality

haze environment will cause serious and irreversible damage to human lungs, and it is also easy to induce cardiovascular disease and respiratory tract infection. Long term exposure to haze environment will even cause lung sclerosis and cancer. Therefore, when haze weather strikes, it is particularly important to take proper protective measures

travel: the choice of masks is very important

when traveling in haze weather, masks are particularly important. PM2.5 particles can penetrate into the alveoli, while ordinary medical or disposable masks can't block the entry and exit of fine particles at all, so we need to choose a special anti haze mask

masks that cannot block haze

multi-layer cotton yarn spliced, disposable medical and activated carbon masks cannot be used as haze masks. For inhalable particles and fine particles in urban air, the filtration rate of facial masks is less than 30%, while activated carbon masks can only be used as an adsorption and blocking odor

how to choose smog masks

common smog masks in the market, when purchasing, it is necessary to first identify the product packaging to see whether it is marked with clear and recognized mask implementation standards. In China, smog masks are divided into kn and KP, in which 90, 95 and 100 are respectively used to distinguish their filtration efficiency. Generally, kn95 and kp100 masks are commonly used. The price of haze masks is generally not low, and cheap products need to be carefully screened

recommended products:

1, Honeywell mask h1005584

2, 3M mask 9001v upgraded version

indoor: choose a good household purifier

air purifier has also become a hot small household appliance in recent years with the haze weather. According to the needs of each family, the use needs of air purifiers are also different, but when buying, we should mainly grasp some of its core components

hepa filter screen

in addition to some products that use electrical dust collection technology now, most purifiers are still presented in the form of filter screens, and HEPA filter screen, as the core component of filtering PM2.5, is also particularly important when purchasing. The high-quality HEPA filter screen is compact in texture and white in color. After being used for a period of time, a large number of fine particles will accumulate inside, but unlike dust, it can be shaken off at will

product scope of application

air purifiers are not available in the whole house. Different products have different applicable areas. When choosing, you need to choose appropriately according to the environmental conditions at home. When people are in different positions at home, you can choose to buy multiple purifiers, or one can move around the home, which needs to be decided according to the budget

recommended products:

1, Philips air purifier ac4030/10

2, Dajin air purifier mck57lmv2

editor's comments: haze has become an environmental phenomenon in China. In addition to committed to improving the natural environment and saving air quality, we can also use small household appliances to improve the air environment around us in the short term. The popularity of air purifiers also reflects people's concern and concern about environmental quality. Only by choosing appropriate products can we maximize the improvement of our living environment
