How to choose an air purifier?Home air purifier

　　With the smog locking the city, consumers are increasingly worried about the smog, and the sales of air purifiers are becoming more and more popular. "Today is still a working day, and only 5 units were sold in one morning. The smog was too heavy, and the sales during New Year's Day were doubled compared to usual." On January 3, a salesperson of Gome Electric Appliances located on Quancheng Road told Female newspaper reporter. On the one hand, consumers have rigid demands for air purifiers. On the other hand, they do not know how to choose when purchasing, which has become a problem for many consumers.

　　The price difference is thousands of dollars. Where is the difference?

　　Mr. Zhang, a citizen of Jinan, suffers from chronic bronchitis and has always wanted to buy an air purifier, but due to the numerous brands, he has been unable to decide which one to buy. "One is that there are many brands, there are domestic and foreign brands, and each of them says that they are good. One is that the functions are different, some focus on removing formaldehyde, while others focus on removing smog. Another is that the price difference is too big, and the functions are similar. The price difference is a few thousand yuan, and I really don’t know what kind of suits to buy.” There are not a few people who have the same confusion as Mr. Zhang.

　　On January 3, a reporter from a female newspaper came to Gome Home Appliances near Quancheng Road. On the second floor, dozens of air purifiers from Samsung, Yadu, Smith, Lake and other brands are being sold at the same time. Taking the two products of Samsung and Yadu as an example, the two products are roughly the same in terms of clean air volume and cumulative purification volume, but the price of Samsung is nearly 2,000 yuan higher than that of both. Salespersons of the two brands said that the actual functions of the two products were roughly the same, but they explained vaguely where the difference was.

　　A salesperson of another domestic brand said: "The domestic product is more in line with China's environment, and the weather quality in many places abroad is better than the domestic one, so the product is not necessarily more suitable for Chinese families than the domestic product."

　　In another home appliance store, a Panasonic salesperson said that some of the brand's air purifiers have a disinfection function, and some products are fully automatic induction, more user-friendly in design, and more functional. The use time is longer and the cost of use is relatively low.”

　　The selection of air purifiers can be based on the "three highs"

　　To choose the right air purifier, you need to first understand how the product works. Qiu Zhaoyun is one of the main drafters of the current national standards for air purifiers. He introduced that in order to make indoor air reach normal standards, the air purifier must first recycle indoor air, pass through the purification device inside the machine, and then discharge it into the room. The fan is the energy source of the air circulation. Generally, the fan with higher power has higher purification efficiency.

　　He said: "For example, the outlet area of a foreign brand machine is relatively small, the air inlet of domestic brands is generally smoother than that of foreign brands, and the outlet area is larger. The reason why Chinese brand products have high purification efficiency is mainly due to the larger air volume. "
