“液体口罩”调查：宣称防新冠抗流感，99%阻隔病毒，靠谱吗？

Core Viewpoint - The article highlights the controversy surrounding liquid mask products marketed as having virus-blocking capabilities, emphasizing that these products are classified as daily necessities rather than medical devices, raising concerns about their efficacy and compliance with advertising regulations [1][10][40]. Product Classification and Claims - Liquid masks are marketed as providing physical protection by forming a barrier in the nasal cavity to block viruses and allergens, with prices ranging from tens to hundreds of yuan [2][4]. - Products like "A Dong" liquid mask claim annual sales of 1 million bottles, while other brands such as BHM and Bentrio also offer similar products [2][4]. - These products are not classified as drugs or medical devices, and their claims of preventing COVID-19 and flu viruses are considered potentially misleading [1][10]. Regulatory Concerns - There are no national standards for liquid masks, and the lack of regulatory oversight raises questions about the validity of their advertised protective claims [1][10][40]. - Experts argue that advertising these products with medical claims violates the Advertising Law of the People's Republic of China, which prohibits non-medical products from making health-related claims [10][15]. Efficacy and Testing - Many claims of high efficacy, such as "99.9% virus blockage," are based on laboratory tests rather than real-world effectiveness, leading to skepticism about their actual protective capabilities [17][24][26]. - The article notes that while some core ingredients may have demonstrated antiviral properties in studies, this does not guarantee the overall effectiveness of the final product [21][22]. Market Dynamics and Consumer Perception - Consumer reviews are mixed, with some praising the products while others criticize them as ineffective or overpriced, indicating a divide in public perception [37][40]. - The marketing strategies of these products often involve comparing them unfavorably to traditional masks, which raises ethical concerns about misleading consumers regarding their protective capabilities [35][38]. Recommendations for Industry Regulation - Experts suggest enhancing regulatory frameworks for liquid masks, including establishing unified standards and increasing oversight to prevent false advertising [40][41]. - There is a call for improved consumer reporting mechanisms to address quality issues and misleading claims in the market [42].
