Where does chaos in the air purification equipment industry come from?
袭击 ” 了国内大部分地区，根据中国气象局的数据显示，此番雾霾波及 25 个省份，一百多个大中型城市，全国平均雾霾天数创五十二年来之最，安徽、湖南、湖北、浙江、江苏等地均创下历史纪录。 A recent wave of haze weather " hit " most of the country. According to data from the China Meteorological Administration, the haze has affected 25 provinces and more than 100 large and medium-sized cities. The average number of haze days in the country hit 52. For the most years, Anhui, Hunan, Hubei, Zhejiang, Jiangsu and other places have set historical records.
口罩经济 ” 。 Against the backdrop of haze weather, people's demand for protection and air purification products continues to rise, and even gave birth to the so-called " mask economy . " PM2.5 、甲醛等有害物质，净化效果达到 99% 以上，不过央视《每周质量报告》近期披露空气净化设备市场乱象：空气净化设备产品存在标称猫腻等问题，部分小型产品臭氧释放量超标，对人体造成伤害。 Air purification equipment has also become a nationally popular product recently. Many products have been targeted at harmful substances such as PM2.5 and formaldehyde, and the purification effect has reached more than 99% . However, the CCTV "Weekly Quality Report" recently disclosed the chaos of the air purification equipment market : The air purification equipment products have problems such as nominal fussiness, and the ozone release of some small products exceeds the standard, causing harm to the human body. The industry also calls for the lack of current air purification equipment industry standards. In addition to safety and other standards, indicators that reflect purification capabilities should also be strengthened in mandatory standards.
、甲醛等有害物质具有净化功能，其中部分产品宣称其净化效果高达 99% 以上。 The author found in the home appliance store that many air purification equipment products sold in the market are claimed to have a purification function for harmful substances such as PM2.5 and formaldehyde, and some of these products claim to have a purification effect of more than 99% . Experts said that to measure the purification capacity of air purification equipment, it is not enough to just understand the removal rate. It also needs to be combined with factors such as the applicable area to comprehensively judge the purification effect of an air purification equipment.
个品牌的空气净化设备产品，并依据上海市强制性的地方标准《 DB31/622-2012 空气净化设备能源效率限定值及能源效率等级》首次进行了质量安全风险监测，发现空气净化设备标高和不标适用面积的现象非常严重，所谓的 “ 适用面积 ” 是指空气净化设备适合使用的最大室内面积，其大小与洁净空气量密切相关。 A few days ago, the Shanghai Municipal Bureau of Quality Supervision and Supervision conducted random inspections on air purification equipment products. A total of 20 brands of air purification equipment products were sampled and based on Shanghai's mandatory local standard " DB31 / 622-2012 Air Purification Equipment Energy Efficiency Limit Values and "Energy Efficiency Rating" carried out quality and safety risk monitoring for the first time, and found that the elevation and non-standard application area of air purification equipment are very serious. The so-called " applicable area " refers to the maximum indoor area suitable for air purification equipment, its size and clean air The quantity is closely related.
种空气净化设备产品没有标注适用面积，其中不乏知名品牌。 The results show that there are 7 types of air purification equipment products that are not marked with applicable area, and many of them are well-known brands. 种实测值没有达到产品标称的适用面积。 Of the remaining products marked with applicable area, 9 measured values did not reach the nominal applicable area of the product. 种既标注了适用面积也标注执行标准的空气净化设备中， 4 种未达到标称值。 Of the 6 types of air purification equipment marked with both applicable area and implementation standards, 4 did not reach the nominal value.
Experts believe that the applicable area of the virtual standard may not only reduce costs and increase sales for enterprises, but this behavior is a violation of the legitimate rights and interests of consumers. 值增大一倍，这就意味着风量、噪音、功率都得大幅度地上升，从总体成本上来看的话大概会增加 1.5 倍左右。 If the applicable area is doubled, it is equivalent to the amount of clean air, that is to say, the CADR value is often doubled, which means that the air volume, noise, and power must be greatly increased. From the perspective of overall cost, it will probably be Increase about 1.5 times.
In addition, many low-cost small air purification equipment products sold online claim that their products can produce ozone, negative ions, can quickly sterilize, remove indoor formaldehyde, benzene, amine and other pollution, as well as reduce blood pressure and improve myocardial function . It is understood that the working principle of this type of small purification equipment products is quite simple, that is, the purification effect is achieved by releasing ozone. 毫克 / 立方米，室内臭氧浓度不能高于 0.16 毫克 / 立方米，超量臭氧会对人体造成伤害。 According to national standards, the ozone concentration of air purification equipment must not be greater than 0.1 mg / m3, and the indoor ozone concentration cannot be higher than 0.16 mg / m3. Excess ozone can cause harm to the human body.
