[Real-time] Canned zero-polluted air can resist? Experts say the effect is not as good as wearing a mask

The emergence of smog gave birth to a new kind of commodity trading - "selling air." Recently, the reporter of Chutian Metropolis Daily saw on the website of many home appliance manufacturers that the “zero-pollution air”, which was nominally purchased from home and abroad, had become a clearly priced commodity.

“Experience the feeling that the purest air is inhaled into the lungs and reduce haze damage to the body.” On a shopping website, Chutian Dushibao reporter saw a variety of canned air products, claiming to have come from Inner Mongolia and Zhejiang. Some indicate that they are from Japan and New Zealand, and the price of each can ranges from tens of dollars to several hundred dollars. The shelf life is about 1 year. Advertising slogans emphasize that it can bring fresh feelings to people. It is a “good medicine” against haze.

The reporter browsed several pages of air sales and saw that the appearance of these canned airs is similar to ordinary air fresheners. The method of use is also very simple. Open the package and point the nozzle at the nose and mouth, and gently press the nozzle. There are also attached breathing masks that press the lid to open the pack so that the so-called "zero-pollution air" can be absorbed. The reporter found that the volume of such products is not much, and the number of customers who comment on messages is also small.

Can "zero-pollution air" really fight smog damage? Zhang Jixian, director of the Department of Respiratory Medicine at the Hubei Hospital of Integrated Traditional Chinese and Western Medicine, said that healthy health must be kept in a fresh air environment for a long period of time. Taking a few cans of so-called non-polluting air for a short time will have little effect on improving human health. Selling "zero pollution air" is more like a gimmick for commercial hype.

Zhang Jixian reminded that the number of patients with respiratory infections admitted to the hospital in the past week has increased by about 30%. When you go out in hazy weather, it's best to wear a mask to prevent it. After the outdoor activities are completed, the nasal cavity should be cleaned with warm salt water of 35°C to 38°C in time to reduce the attachment of harmful particles in the nasal cavity.
