Although it is still not conclusive, it is believed that "Smog" will become a hot word for China in 2013. Everyone also slowly "habits" from the earliest changes, and it can be said to be resigned to acceptance. The year 2013 was also due to smog, a household electrical appliance that did not even appear in the market five years ago.

Fires sold by purifiers have no regulatory standards. Market competition is currently chaotic. Currently, prices of air purifiers sold in the market range from a few hundred yuan to over 10,000 yuan. Almost all air purifiers promote "effective removal of PM2.5" and "PM2.5 nemesis" as selling points. Companies engaged in production and business activities include Japanese, Korean, domestic and other home appliance companies. Starting from the earliest Sharp and Panasonic air purifiers, a large number of home appliance companies joined with the increase in product heat. Today, almost all well-known home appliance brands are released. Air purifier products. Today's home appliance stores also place air purifiers in the most prominent locations for promotion. According to the data from China Yikang, the sales of air purifiers in the ion filtration system increased by 94.6% year-on-year in the previous eight months, the activated carbon air purifiers increased by 68.7%, and the air purifiers equipped with catalyst filtration systems increased by 58.9%.

The author's investigation found that at present, there are many manufacturers of household air purifiers in China, and the majority of them are small and medium enterprises in the “Yangtze River Delta and Pearl River Delta” markets. The market is relatively chaotic and the competition is disorderly. Ma Cong, deputy chief editor of China's State Grid, told reporters that air purifiers are not furnishings or comfort products. Some big brands of products, through inspections by authoritative departments, can remove PM2.5 and various harmful substances well. But there are also a large number of products known as air purifiers that actually have only an ionizer (which is not the same name) or that the filter is simply not capable of removing PM2.5 at all. Consumers need to polish their eyes and must not covet for cheap . Columnist Hu Hongsen said that recently, the topic of removing various PM2.5 purifiers and air conditioners has continued. The fundamental reason is that manufacturers use PM2.5 for promotion, but they are only a psychological means to capture the psychological needs of consumers. It is very likely that sales of products will be exaggerated in terms of functionality.

In an interview with a reporter from a Japanese Sharp company that has produced air purifiers for several decades, the PM2.5 has a much smaller diameter than the PM10 respirable particulate matter. Generally, the filter in the air purifier cannot be effectively filtered. The HEPA filters made of propylene and polyethylene can filter fine particles with a diameter of 0.1 μm. The removal effect of solid particles with an air diameter of 2.5 μm or less (ie, PM2.5) can be eliminated. Pay special attention to the type of filter. Hisense air conditioning related person in charge told reporters that the removal of PM2.5 is a complicated process. Taking Hisense PM2.5 air conditioning as an example, it needs to be removed through the steps of anion release, PM2.5 attachment, and strong electric field purification and filtration. There are quite a few "technical content" links, and companies that do not have a certain R&D technology base can hardly produce products that effectively remove PM2.5 in a short period of time.

What is the reason for the confusion in the air purifier market? Ma Cong, deputy chief editor of the State Grid Corporation of China, pointed out that with respect to air purifier products, the country does not currently have relevant standards, which is the root cause of this chaos.

Yang Fan, a senior expert in the home appliance industry, told reporters that due to the surge in demand, there have been various products of varying quality in the market. However, air purification is a kind of "invisible touch" action, so it is difficult for consumers to distinguish between good and bad. As a national relevant unit, relevant standards and norms should be issued in this field so as to further improve the market while protecting the interests of consumers as well as the interests of the enterprise.

Low threshold for production of small home appliances, fake goods, fake goods, and so on, so-called small appliances, in fact, there is no exact definition, in general, will television, refrigerators, washing machines, air conditioners, smoke cookers and other home appliances other than large appliances, collectively For small appliances. For example, our common hair dryers, irons, humidifiers, electric razors and other products can be called small appliances. Small household appliances are often small products with low prices and simple functions. Although top brands have some patented core technologies, in general, entry barriers are the lowest among all home appliances, and even many well-known brands use OEM stickers. The way of licensing is to operate small household appliances. It is because the threshold is too low, which has led to frequent market chaos, mainly reflected in several aspects such as counterfeiting of well-known brands and unqualified quality and after-sales protection.

According to media reports earlier, the Shanghai Municipal Administration for Industry and Commerce announced the results of monitoring the quality of small household appliances involving 28 batches of 28 brands sold by 6 websites such as Yixun, Xinji, Bailian E City, Jingdong Mall and No. 1 Store. The results showed that up to 15 batches of small household appliances, including humidifiers, steamers, and rice cookers, were unqualified, and the failure rate was 33.3%, exceeding 30%. Among them, the failure rate of Bealead E City and Jingdong Mall was 42.9%. The Beijing Municipal Administration for Industry and Commerce also announced earlier this year that as many as 54 unqualified home appliances with potential safety hazards were discovered in the quality monitoring of various small home appliances sold in the Beijing market. Among them, there are 8 kinds of home appliances that fail to get in touch according to the site, and the hidden danger is even greater.

The Trade and Industry Bureau reminds consumers that when shopping online for small household appliances, they should learn more about the important names of the purchased goods, manufacturers, product model specifications, rated power, rated voltage, power supply type and frequency, after-sales service, and other important information; Manual and 3C certification mark. At present, China implements 3C certification for 18 major categories of household electrical appliances. It belongs to the 18 major categories of products and can check whether there is a 3C certification mark. Inspection products can be viewed for inspection reports that do not belong to the 18 categories of household electrical appliances. The validity of inspection reports is generally one year. .

In addition, as for the market chaos of small household appliances, the industry veteran Yang Fan said that consumers should pay special attention to the purchase. Small household appliances are small, but safety issues cannot be ignored, such as electric kettles and electric irons. If there is a security problem, it may even directly threaten life's safety. When consumers purchase small home appliances, they should not be greedy and cheap, they should shop around, and especially pay attention to whether the product has any after-sales service commitment and try to purchase guaranteed home appliances.
