In response to the claims about the accuracy of portable formaldehyde detectors and the market chaos related to products for removing formaldehyde, consumer associations in Beijing, Tianjin, and Hebei jointly launched a rectification campaign. Scientific explanations pointed out that the claimed 99.9% detection accuracy by some manufacturers lacks basis, as electrochemical sensors suffer significant errors due to factors such as temperature and humidity. Such instruments can only provide rough references and cannot replace professional testing. As a result, the consumer associations in Beijing, Tianjin, and Hebei have contacted 8 brand companies including Hope Tree, Honeywell, and Shanshan, as well as some e-commerce platforms and MCN institutions, demanding that they fulfill their responsibilities, strictly control false advertising and misleading propaganda, and advising the public to use qualified environmentally friendly materials, maintain good ventilation, and undergo professional testing when necessary to assess the risk of formaldehyde.
Some merchants claim that portable formaldehyde detectors have a precision of 99.9%. However, the “Science Debunking” official account points out that this claim has no scientific basis, as electrochemical sensors are affected by costs, temperature, and humidity, resulting in large and erratic errors in test results. The consumer associations in Beijing, Tianjin, and Hebei tested 50 brands of products, and none could accurately measure the formaldehyde content. Such instruments can only serve as a rough reference and cannot replace professional testing. To assess the risk of formaldehyde, it is necessary to use qualified environmentally friendly materials, maintain good ventilation, and conduct professional testing when necessary. In addition, the consumer associations in Beijing, Tianjin, and Hebei also intervened against false and exaggerated promotions in the markets for formaldehyde detectors and “甲醛-removing jelly” products. They held talks with 8 brand companies including Hope Tree, Honeywell, and Shanshan, as well as some e-commerce platforms and MCN institutions, demanding that they take responsibility for their actions and strictly control false advertising and misleading promotions.
