Mist and burst table! Disaster weather how we protect ourselves

Autumn and winter are the high season for haze. In recent years, the problem of environmental pollution has become more and more serious. The haze problem has also received widespread attention. In the past two days, the north was sent to the south, and Shanghai and Jiangsu were "depressed." At 9:00 am on December 15, the data from the Shanghai Municipal Environmental Monitoring Center showed that the real-time air quality index reached a level of 316 with serious pollution. The primary pollutant was PM2.5, and the air quality index was 254 in the past 24 hours, which was severe pollution. Then when smog strikes, what kind of products should we choose, and how can we achieve self-protection correctly?

How to correctly understand the haze

In fact, haze weather has a long history. In recent years, due to the accumulation of environmental problems, smog problems have also started to occur frequently. In many areas, PM2.5 popping phenomenon may even occur. The haze in the north mainly comes from heating and burning coal. Exhaust gas, which is actually a combination of the words “fog” and “霾”, and our common PM2.5 is the particle with an aerodynamic equivalent diameter of less than 2.5 microns in the environment, which is also measured as air. An important indicator of quality.

The haze environment can cause serious and irreversible damage to the human lungs. It can also easily induce cardiovascular diseases and respiratory infections. It can even cause lung cancer to become hardened and cancerous when it is in a hazy environment for a long time. Therefore, when fog and haze weather strikes, it is particularly important to make proper protective measures.

Travel: mask selection is very important

In smog weather, masks are particularly important. PM2.5 particles can penetrate deep into the alveoli, and ordinary medical or disposable masks are completely inaccessible to fine particles. Therefore, we need to choose a special anti-haze mask.

Unable to block smog masks

Multi-layered cotton splices, disposable medical and activated carbon masks cannot be used as smog masks. For inhalable particles and fine particles in urban air, the filtering rate of facial masks is less than 30%, and activated carbon masks are more Can be used as an adsorption, blocking the presence of odors.

How to choose a smog mask

On the market, common smog masks need to be identified at the time of purchase to see if they are marked with a clear and approved mask implementation standard. In China, smog masks are divided into KN and KP categories. In the two categories, there are 90, 95, and 100, respectively, as the distinction of their filtering efficiency. In general, KN95 and KP100 masks are more commonly used. Mist masks are generally sold at low prices. Careful screening is required for cheap products.

Indoor: choose a home purifier

Air purifiers have also become hot in recent years due to haze. Smaller home appliances have different requirements for air purifiers depending on the needs of individual households. However, when purchasing, they mainly need to grasp some of their core components. .

HEPA filter

In addition to the products that currently use electric dust collection technology, most of the purifiers are still presented in the form of filters. The HEPA filter, which is the core component of filtering PM2.5, is also very important when it is purchased. The high-quality HEPA filter is dense in texture and white in color. After a period of use, a large amount of fine particles accumulate inside, but unlike the dust, it can be shaken off.

The scope of products

Air purifiers are not available in the whole house. Different products have different applicable areas. When selecting, they need to be properly selected according to the environmental conditions in the home. When people are in different locations at home, they can choose to purchase more than one purifier or one at home. Moving around, this depends on the budget.

Editor Comments: The haze has become an environmental phenomenon in China. In addition to efforts to improve the natural environment to save air quality, in the short term we can also use small appliances to improve the air environment around us. The great heat of air purifiers also reflects people’s concerns and concerns about environmental quality. Choosing the right products can maximize our living environment.
