Survey by reporter Convenient stores and pharmacies have placed the tamper-proof masks in a conspicuous position these days. The best-selling 3M mask with exhalation valve costs 48 yuan. There are not many online shops selling tens of thousands of phlegm-masks every month, and an online shop has sold more than 40,000 pieces of “activated carbon dust-proof and dust-proof masks†every month. professional advice Ordinary single-layer masks and medical masks have almost no effect of filtering PM2.5. When selecting masks, look for regular manufacturers and particulate protection standards. The effect of flood prevention is also closely related to the degree of confinement of the mask. If the effectiveness of the mask leakage protection is greatly reduced Weather warning The air quality level in Chengdu was moderate to severe from the 7th to the 9th, and the primary pollutants were all PM2.5. From 7th to 9th, Chengdu had no weather conditions conducive to artificial rainfall. Flood prevention, letter black technology or soil approach? There are moderate to severe haze in the next 3 days. From the evening of the 5th to the afternoon of the 6th, Chengdu-level related departments and districts (cities) and counties mobilized nearly 35,000 people in total, and increased their supervision of the 'warfare work'. ■Tianfu Morning Post reporter Zhang Fuchao comprehensive report In the past few days, various anti-mite measures have been taken to the streets, wearing masks, scarfs, and air purifiers installed at home, and even some of them have never been seen before. However, many people have said that it is still more effective for people to adopt popular methods such as drinking white fungus soup and eating blood. What is your choice? Here's an early look at what you might not know about the "anti-black technology" and the earth approach. Wear black technology Black Technology Index ★★★★☆ Anti-virus anti-fog and dust mask The world's only active defense anti-virus mask was successfully developed in Wuhan Optics Valley. This King Kong mask will revolutionize the mask industry. Its performance in dust prevention (including PM2.5 prevention, anti-virus, anti-virus, anti-pollution and anti-smoke) will reach 99.99%, and it will also provide fresh and healthy wearers. Rich oxygen. At present, this kind of active defense anti-virus mask has been put on the market. Black Technology Index ★★★★★ Smart anti-muffle scarf This seemingly influx of scarves actually has a very good air purification effect. This scarf is blended in the cashmere with a special crystal structure of carbon magnesium ion material, the electrostatic discharge of this material has a radius of 35cm. This kind of static electricity has a particle diameter of less than 2.5 microns, especially the positive electrode particles containing organic carbon. Extremely repulsive. Black Technology Index ★★★★★ Fixed black technology Air purification tower The foreign guy Daan Roosegaarde hopes to use ion purification technology to create a giant “vacuum cleaner†that can purify the air throughout the city. The air purification tower can purify 30,000 cubic meters of air per hour. The appearance of the purification tower is a white shutter structure, which can inhale contaminated air and purify the clean air. Black Technology Index ★★★★★ "Giant foam" anti fog Orproject Design, London, United Kingdom, plans to build a "huge bubble" that can enclose the park. At the same time, the school playground can also be wrapped in this small clean air system. This park contains a large botanical garden, completely isolated from the outside environment, providing perfect clean air. Black Technology Index ★★★★☆ Mobile Black Technology Self-contained baby carriage The Air Shield has the same structure as the car warehouse, taking into account multiple factors such as air quality, temperature, noise, and sun protection when outdoors. The protective glass cover on the top of the body can effectively isolate the baby from the external environment, and has an air purification function inside. The baby can not only breathe fresh air, but also can be protected from external ultraviolet radiation and noise. The Air Shield has a built-in microphone so parents can perceive the baby's voice in the car. Many people have said that these black technologies can be used as they are. However, if they are really used, I am afraid that the effect of the local approach is even faster. The reporter gathered several kinds of vegetable food therapy, tea diet therapy, and respiratory health law.
