Whether they hide harmful substances or their protective capabilities are a public concern. The Consumer Foundation today announced the results of random inspections. 30% of the samples were found to have less than 80% protection against fine particulate matter (PM2.5), and 3 heavy metal lead samples were found. Other colorants, volatile organic compounds, etc. were partially detected, requesting the government Relevant standards should be formulated and people should give priority to products with colorless inner layers when purchasing.According to the Consumer Foundation, the 20 mask test samples were purchased from Shuangbei hypermarkets, pharmacy chains and e-commerce platforms in December last year, including 19 medical masks and 1 general disposable mask. The unit price is 3.4. 14 yuan, heavy metal lead, cadmium, antimony, nonylphenol and nonylphenol polyoxyethylene ether, free formaldehyde and plasticizer, dye elution, volatile organic compounds, PM2.5 filtration efficiency, etc. are tested.

It also reminds consumers to prioritize choosing white, blue and green products with colorless inner layers to reduce doubts about the safety of the dye.
