Haze boosts "hot" air purifiers

Recently, haze weather has become an important factor affecting people's lives. How to prevent and prevent it becomes a new topic. Since the haze yellow warning was lifted by Shandong Province on the 22nd, the haze has caused the air purifier to become a new star on the market. The reporter learned that the prices of these air purifiers ranged from a few thousand dollars to several tens of thousands, and declared that 99% removed pollutants such as formaldehyde and PM2.5. The reporter learned that the current air purifier industry does not have a unified mandatory quality inspection standard, and the functions advertised by air purifier manufacturers are often exaggerated.

Frequently hit by fog and haze

On the 22nd, the reporter came to several large commercial buildings in Tengzhou and discovered that the air purifier has become a popular target for the public. The reporter saw in one of the commercial buildings that the air purifier of a well-known brand was placed in a conspicuous position. The publicity column in front of the brand's air purifier counter read the words “clear haze” although it was almost noon. However, there are also many people who come to consult. When one of the citizens consulted the sales staff about the function of the air purifier, the sales staff introduced that the formaldehyde in the room, pollen, TVOC odor, etc. can all play a good role in cleaning and purifying the air. When a reporter asked whether it was possible to purify the "fog and haze" that floated into the room, the salesperson preached that there was actually a certain effect, but whether or not he could thoroughly purify it, she had to consult the manufacturer to know.

At the same time, the salesman told reporters that this year's air purifiers sold better than in previous years. In previous years, air purifiers were "cold" products. Recently, hazy weather has been frequent. People with children at home have come to consult and have the intention to purchase. "Some families buy two or three at a time, one in the living room and one in the bedroom," the salesman said. At the exhibition stand, the reporter observed that the price of air purifiers ranged from a few thousand yuan to ten thousand yuan. In particular, some air purifiers with low prices and full functions were highly praised by the public.

Not only is the popularity of physical store air purifiers high, but sales of online air purifiers have also risen in a straight line. An online shop has already sent a letter of apology: “The shop orders have been soaring due to the hazy weather. During this period, if the shop did not provide attentive service, please forgive me.” When looking at the webpage, the reporter noticed that one of the prices The best selling air purifier for 1599 yuan, 2571 monthly sales. Other shops have the words "micro spot".

There is no effect of purification, most businesses “empty”

The reporter learned that many air purifier products have been declared to have the function of purifying PM2.5, formaldehyde and other harmful substances. Many of the air purifier products have played "PM2.5 removal rate of 99%" and "formaldehyde purification. The slogan with a rate of 99%. However, the effectiveness of the project and whether it can give written documents prove that most agents are unclear and cannot obtain relevant inspection certificates.

In one of the large commercial buildings, just as an air purifier agent's home is on the scene, many citizens are more concerned about the removal effects of pollutants such as formaldehyde, benzene, and PM2.5. In these respects, merchants can guarantee it. "The removal rate can reach 99%. Any air pollutants can be removed. Generally, it can be recycled 2 to 6 times an hour. In some purifiers, electronic eyes are installed. If the indoor pollution is relatively high, then the electronic eye will show red. After 10 minutes, it will turn green, which means that the interior has completed a purification.” But when the reporter asked if they could look at the test report, the merchant refused to use the test certificate for various reasons.

Expert statement

There is no clearly defined standard that can easily be over-promoted

The reporter learned from relevant departments that at present, the definition of air purifiers is difficult. Without a unified standard, the so-called purification performance of different purifier products is also basically not comparable. For example, it is also claimed that the formaldehyde purifying effect can reach 98%, and some purifiers only need one or two hours to reach, and some purifiers need more than ten hours. Therefore, some air purifier products implement recommended national standards, while others implement their own corporate standards. If there is no mandatory national standard, the air purifier market is prone to excessive propaganda and confusion of concepts.

Experts pointed out that the current air purifier standard is only partly stipulated in terms of safety and performance, but the stipulations on the purification efficiency of comprehensive application area and other factors are not detailed enough, and basically all are recommended standards. It is difficult for enterprises to have enforcement capabilities and it is difficult to determine. These purifier products failed. An industry source told reporters: "When purchasing an air purifier, or according to their actual situation, can not be one-sided to follow the recommendation and introduction of shopping guide, pay attention to the purifier parameters, applicable area, etc., must be done before the purchase There is something in my mind. Do not think blindly that yours is good."
