In case of “smog” air purifier is hot, the actual purification function needs to be improved
Shanghai Renshoutang Sinopharm on Beihong Road and Yifeng Pharmacy on Tianshan West Road… The reporter visited a number of pharmacies in Shanghai yesterday and found that a variety of masks were placed in the conspicuous window, including children’s masks and adult daily masks. And the most preventive PM2.5 masks. The reporter noted that among these mask products, the price of one-time anti-mite masks (three bags of one bag) is about 25-30 yuan, and the price of non-disposable moth masks is more expensive, basically at around 40 yuan.
“Many companies concentrate on ordering masks for employees, and corporate orders are increasing. The purchase volume of individual customers is relatively stable, but compared with a few years ago, the increase in mask sales in the same period of this year is very obvious.” A pharmacy salesperson told reporters that As the smog enters a high incidence period, the sales of FITs in masks continue to increase. In addition to a physical business, the words “must mask” are entered on the web platform, and there are hundreds of products for sale. In the official flagship store of 3M, a 20-piece N95 headband anti-fog mask with a price of 138 yuan, the total sales exceeded 100,000, the monthly sales broke 5,000 boxes, and the other 25 pieces were sold, sold and sold. The monthly sales of the “Dust-proof smog PM2.5 mask” with a price of 158 yuan reached more than 7,000 boxes.
In addition to the anti-mite mask, the top 5 best air purifiers have become the choice of “defense” after New Year’s Day. In the Changle Road store of Yongle Electric, the reporter noticed that all major brands will have air purifiers with the effect of removing cockroaches in a conspicuous position. The reporter noticed that the price of the air purifier with the main function of removing the cockroach is in the range of 2999-3599 yuan, while the price of the multifunctional air purifier is basically above 4999 yuan. In terms of purification function, most models of particulate matter removal and formaldehyde purification energy efficiency levels are shown as high efficiency.
It is worth noting that China’s first top 10 best air purifiers China environmental labeling standard has been implemented since January 1 this year. After the implementation of the standard, consumers can use the Chinese environmental label on the purifier product as one of the important basis for purchasing the product. When the salesperson introduced the product to the reporter, he pointed out that the sign was posted on the shelf purifier in the mall. The relevant person in charge of Suning Shanghai disclosed to reporters that since the New Year’s Day, the sales of air purifiers in Shencheng Suning’s physical stores have increased by 170% year-on-year and by 250%.
The sales staff told reporters that in addition to the purchase of individual customers, the orders of enterprises during the New Year’s Day increased significantly. “Business procurement is used for air purification in offices, and most of them are for the health of employees.”
Actual purification function needs to be improved
The demand for anti-mite products has surged, but the efficacy of anti-mite products has actually been improved.
The Municipal Consumer Protection Committee disclosed that of the 20 mainstream brand air purifier products, 12 were purchased in large department stores, and 8 were purchased on e-commerce platforms, with prices ranging from 699 yuan to 18,600 yuan per unit. The comparative test was carried out for product promotion and consumer-focused particulate matter purification functions (clean air volume, applicable area, PM2.5, 0.1μm to 0.2μm particulate matter), gaseous pollutant purification function (formaldehyde, sulfur dioxide) and other projects.
The results showed that among the 20 samples, the purification ability of formaldehyde and sulfur dioxide was quite different. The nominal value of some enterprise product functions differed from the measured values. Among them, 20 samples of PM2.5 clean air volume highest and lowest value, the measured difference is more than 7 times. The maximum value of the clean air and the minimum value of the particle size of 20 samples from 0.1 μm to 0.2 μm are also more than 7 times. 20 samples of sulfur dioxide clean air, the highest value and the lowest value difference of 27 times.
According to another report, 11 samples of the nominal formaldehyde clean air quantity value are found in the new national standard of the air purifier, “the measured value of the clean air volume should not be less than 90% of the nominal value”, and the nominal Panasonic Environmental System is found. A “Panasonic” air sterilizer produced by the company is not consistent with the measured values and does not meet the standard requirements.
In addition, the nominal value of some enterprise product functions is quite different from the measured value, such as an “Olansi” air purifier, which is nominally produced by Zhejiang Wuyi Youdun Electric Co., Ltd., and the measured applicable area is much smaller than the standard value.
Selection and use should be properly selected
The Municipal Consumer Protection Committee pointed out that consumers should purchase air purifier products through formal channels, avoid buying “three no” products and ensure the quality and after-sales of products. Purchasing air purifiers according to their actual needs, such as smog-prone areas can focus on PM2.5 and other products with strong purification ability of particulate matter, the indoor new decoration can focus on formaldehyde and toluene and other volatile organic compounds purification products. Attention should be paid to the particulate clean air volume (CADR) and the applicable area of the air purifier, which are directly proportional to each other. Do not leave the applicable area and look at the size of the CADR. At least the air purifier with a product area not less than the actual use area should be selected.
In addition, consumers can also focus on purifying energy efficiency levels. Air purifiers are usually used continuously for a long time. The energy efficiency rating is an important indicator to measure the purifying performance and power consumption of the air purifier. The higher the level, the more energy saving. Pay attention to the inspection and verification report. It is recommended that consumers ask the manufacturer to provide a third-party inspection agency test report with the “CMA” mark when purchasing, to confirm that the measured values, test methods and product promotion of each indicator are consistent, and focus on Rationality and effectiveness of the standards and test methods.
