【直报网6月15日讯】（《消费者报道》）除了PM2.5之类的颗粒物和甲醛之类的气态污染物，空气中还有各种各样的细菌会危害人体的健康。为了进一步净化空气，带有除菌功能的空气净化器应运而生；但另一方面，这类空气净化器所采用的除菌技术有可能会产生臭氧，从而伤害人体。

CNDSN June 16 news "(" consumer reports "), in addition to the gaseous pollutants such as PM2.5 particles and formaldehyde and the like, in the air and a variety of bacteria will harm to the human body health. In order to further purify the air, with sterilization function of the air purifier arises at the historic moment; but on the other hand, this type of air purifier the sterilization technology may can produce ozone, and harm to the human body.

《消费者报道》今年4月送检的5品牌空气净化器，除小米和美的之外，安利、完美和夏普均带有除菌功能。检测结果显示，这三款可除菌的净化器1小时除菌率均高于99%；而在臭氧释放方面，5品牌净化器也全部合格。

"Consumer reports" in April this year, the submission of 5 brands of air purifier, in addition to the millet and beauty, Amway, perfect and Xia Pujun with sterilization function. Test results showed that the three can sterilization purifier 1 hour sterilization rate is higher than 99%; and in the ozone release, 5 brand purifiers are all qualified.

3品牌净化器除菌率均较高

3 brand purifier sterilization rate is higher

目前市面上空气净化器的除菌功能主要通过光触媒、负离子、紫外线、TiO2、臭氧发生器等来实现。国家标准GB 21551.3-2010《家用和类似用途电器的抗菌、除菌、净化功能 空气净化器的特殊要求》规定，在模拟现场和现场试验条件下运行1小时，空气净化器的抗菌(除菌)率应不小于50%。

Currently available air purifier sterilization function mainly through the photocatalyst, negative ions, ultraviolet, TiO2, ozone generator to achieve. National standard GB 21551.3-2010 the household and similar electrical appliances antibacterial, sterilization, purification function of air purifier special requirements "specified, run for 1 hour in the simulation test and field test conditions, the air purifier antibacterial (sterilization) rate should be not less than 50%.

本刊此次送检的净化器中，3款带除菌功能的净化器所采用的技术和材料各不相同；不过依据上述标准所做的检测结果显示，这3款净化器的除菌能力都很强(见图5)，其中安利最高，其次是完美和夏普。

The publication censorship purifier, paragraph 3 with sterilization function of the purifier using techniques and materials vary; but based on the standard in the test results showed that, the three purifier sterilization ability is very strong (see Figure 5) in which Amway is the highest, followed by the perfect and sharp.

参与此次检测的工程师向本刊记者分析道：“安利的除菌率最高与它的高CADR值不无关系，在同样的实验室环境下同样的时间内，它换气的次数最多。”

Engineer engaged in the inspection to this print journalist analysis way: "Amway sterilization rate highest with its high Cadr values are not unrelated, within the same time in the same laboratory environment, the number of its ventilation most."

不过需要注意的是，对于采用HEPA滤网除菌的净化器而言，细菌只是被滤网阻拦而并非被消灭，消费者需及时清洁滤网，以免造成二次污染。TiO2和净离子群技术由于可以杀灭细菌，则不存在这种风险。

However, the need to pay attention to the HEPA filter sterilization purifier, bacteria are filter block and not be destroyed, consumers need to timely clean the filter, in order to avoid the secondary pollution. TiO2 and net ion group technology can kill bacteria, it does not exist this risk.

对于除菌功能，完美(中国)有限公司表示，完美空气净化器的颗粒物过滤器增加了灭菌材料，“能有效避免颗粒物滋生细菌的风险”。

For sterilization function, perfect (China) Co., Ltd. said that perfect air purifier particle filters to increase the sterilization material, "can effectively avoid the breeding of bacteria and particles of risk."

5 purifier ozone release are qualified

无论何种空气净化器，使用过程中都会产生一些臭氧，尤其是通过臭氧发生器或紫外线来杀菌的净化器。臭氧主要是刺激和损害呼吸道，并会损害中枢神经系统。当大气中臭氧浓度为0.1mg/m3时，会引起鼻和喉头粘膜的刺激。

No matter what air purifier, the use of the process will produce some ozone, especially by ozone generator or ultraviolet light to sterilization of the purifier. Ozone is mainly to stimulate and damage the respiratory tract, and will damage the central nervous system. When the atmospheric ozone concentration is 0.1mg/m3, will cause the nose and throat mucosal irritation.

GB 21551.3-2010规定，空气净化器开启后，在出风口5cm处的臭氧浓度应小于等于0.1mg/m3。本刊的检测结果显示，5款空气净化器的臭氧释放量全部合格，并且均小于0.003mg/m3。

21551.3-2010 GB provides that the ozone concentration at the outlet 5cm should be less than or equal to 0.1mg/m3 when the air purifier is opened. The results of the publication show that the ozone release of the 5 air cleaners are all qualified, and are less than 0.003mg/m3.

在这5款空气净化器中，完美宜悦去除TVOC时用到了光触媒和UV-A紫外线技术。“我们选用的是365nm特定波长的LED紫外灯，整个光催化反应既不会产生臭氧，而且LED灯使用寿命长。”完美(中国)有限公司相关人员这样解释道。

The 5 air purifier, Yi Yue perfect removal of TVOC used UV-A photocatalyst and UV technology. "We chose the LED UV lamp with a specific wavelength of 365nm, and the whole photocatalytic reaction would not produce ozone, and the LED lamp had a long service life.." The perfect (China) Co., Ltd. explained that the relevant personnel.

这一说法得到了广州工业微生物检测中心高级工程师杨冠东的证实：“如果用的是常规紫外灯(含185nm和253.7nm两种波长)，就会产生臭氧；而如果用的是365nm波长的紫外光，就不会产生臭氧。”

This argument has been confirmed by a senior engineer of Guangzhou industrial microbiological testing center Guan Dong Yang: "if using conventional UV lamp (including 185 nm and 253.7nm two wavelength), it will produce ozone; and if the wavelength of 365nm UV light, won't produce ozone."

可资对照的是，本刊去年1月对市面上6大品牌净化器所做的检测结果显示，6款净化器的臭氧释放量也全部合格。不过在中国家用电器研究院标准事业部主任朱焰看来，这也并不表示正规企业生产的空气净化器其臭氧释放量就都合格，“还是有一些会存在不合格的情况”。▲

To the control, the publication of the last January on the market 6 brands purifier testing results show that the ozone release of the 6 models are also all qualified. But in the eyes of Yan Zhu, director of the China Household Electric Appliance Research Institute of standard business. This does not mean that regular production of air purifier of the ozone emission is qualified, there are still some unqualified ". 3
