On September 26th, the household aldehyde removal technology, aldehyde measurement method and related product performance seminar sponsored by China Household Electrical Appliances Research Institute and the Science and Technology Club Innovation Forum were held in Beijing. The results of the experiment revealed that the public has adopted more The effect of formaldehyde removal method, and invites formaldehyde detection equipment, air purifiers and fresh air system manufacturers to recommend testing, scientific methods and equipment to remove indoor formaldehyde.
Recently, the news that Ali employees stayed in the formaldehyde room and caused the death of leukemia caused widespread concern in the society. For a time, the public talked about formaldehyde color change, and how to detect and eliminate indoor formaldehyde pollution became the common concern of consumers.

Lu Jianguo, director of the Institute of Testing Technology of China Household Electrical Appliances Research Institute, said that compared with PM2.5 and other visible solid pollutants, formaldehyde and other gaseous pollutants are easily overlooked. He stressed that indoor pollution is not terrible. The key is to have a correct understanding and use the right methods and tools to deal with it.
In order to remove formaldehyde, people use almost all kinds of equipment and methods, including green plants, activated carbon bags, photocatalyst sprays, formaldehyde scavengers, air purifiers and fresh air systems, but which way is more effective?
Zhang Weichao, Chief Engineer, Health Appliance Testing Center, China Household Electrical Appliances Research Institute
In this regard, the China Household Electrical Appliances Research Institute Health Appliance Testing Center conducted an effect test on the above six formaldehyde-removing products. According to Zhang Weichao, the chief engineer of the Health Appliance Testing Center of China Household Electrical Appliances Research Institute, from the results, green plants, activated carbon bags, Photocatalyst spray and formaldehyde scavenger have far less formaldehyde removal rate than air purifiers and new fan products. It is not enough to remove formaldehyde by green plant, activated carbon bag, photocatalyst spray, etc., or rely on air purifier and new Fan products.
At the same time, Zhang Weichao also talked about the advantages and disadvantages of air purifiers and new fans in addition to formaldehyde: Air purifiers are portable, no installation, and the purification speed is faster in confined spaces, but the formaldehyde purifiers of air purifiers need regular Replacement, high cost of filter consumables, and long-term use in confined space, easily lead to excessive carbon dioxide concentration in the room, resulting in lack of oxygen; new air blowers can effectively reduce indoor carbon dioxide content compared to air purifiers, and no need to install filters, save Cost, but new fans need to be installed, especially the installation of ceiling fans requires a large number of pipes. Due to the ventilation of the new fan studio and the outside, the ventilation pipes are easily contaminated and difficult to clean. In addition, the new fan test is a single cabin test, formaldehyde removal. The effect is obvious, but in practical applications, the installation of new fans into multiple rooms will have the effect of airflow, and the effect will be worse.
Xiao Jinhua, Deputy General Manager/Senior Engineer of Wuhan Sifang Optoelectronics Technology Co., Ltd.
For the detection method and equipment of formaldehyde, Xiao Jinhua, deputy general manager/senior engineer of Wuhan Sifang Optoelectronics Technology Co., Ltd. explained. At present, there are many kinds of testing equipment on the market, but different equipment costs and effects are very different, such as formaldehyde test strips, although The price is cheap, the operation is simple, but the test result is large in error and subject to subjective influence. Therefore, Xiao Jinhua does not recommend consumers to use semiconductor formaldehyde detector or formaldehyde test strip, but instead recommends using electrochemical formaldehyde detector, if consumers 2. Conditional, you can buy professional grade electrochemical formaldehyde detector or spectrophotometric formaldehyde detector.

Beijing Yadu Environmental Protection Technology Co., Ltd., Ao Smith (China) Water Heater Co., Ltd., Beijing Sanhuan Environmental Protection Technology Co., Ltd., Zhejiang Xingyue Electric Co., Ltd. (dreamer Xinfeng) and Jiangsu Guomai Environmental Protection Technology Co., Ltd. and other air purifiers Representatives of the production companies of the fresh air system introduced the technologies and products of formaldehyde removal in each company: The Yadu air purifier uses platinum titanium dioxide to catalytically decompose formaldehyde technology, and the formaldehyde clean air volume (CADR) can reach more than 500m3/h; AO Smith formaldehyde The new purifier adopts Air-Reborn high-efficiency aldehyde removal formula, which adsorbs formaldehyde in a targeted manner. At the same time, it adopts four-layer and eight-sided structure, and the adsorption efficiency is increased by 2 times. The product is also equipped with high-precision laboratory-level sensor, and the formaldehyde value is monitored once per second. Second-time update, convenient for consumers to monitor indoor air pollution in real time; 352 home new fans can reduce indoor and outdoor temperature difference and improve product comfort while solving air pollution; Dreamer fresh air uses five-layer tower purification, ion Technology can be sterilized without ozone and other technologies, and at the same time, intelligent operation can be realized through the dreamer air babe. Control; GMAIR fruit fresh air adopts the principle of micro-positive pressure purification, while conveying clean air to the room, it can prevent outside air from infiltrating into the room and form an air shield indoors.
