A revised mandatory national standard for disposable medical protective masks, GB 19083-2023, officially came into effect on December 1. The most notable change is the prohibition of exhalation valves on such masks. This adjustment aims to prevent unfiltered exhaled air from spreading pathogens, ensuring bidirectional protection in medical settings . The new standard replaces the 2010 version and strengthens infection control measures.
Design Requirements: Nose Clips for Secure Fit
To enhance protection effectiveness, the standard mandates that all disposable medical masks must be equipped with a nose clip or alternative design. This component ensures a tight seal and stable fit on the wearer’s face, reducing air leakage around the nose area . Elastic or adjustable ear straps are also required to maintain proper positioning during use, balancing comfort and protective performance.
Clear Labeling on Minimum Sales Units
The new regulation specifies detailed labeling requirements for product packaging. Each minimum sales unit must display clear Chinese markings, including expiration date, the standard number (GB 19083-2023), and a “single-use” label or symbol . These labels help users identify qualified products and use them correctly, supporting better public health protection.
The implementation of GB 19083-2023 reflects China’s efforts to optimize medical protection standards. By addressing key safety gaps, the standard provides stronger safeguards for healthcare workers and patients alike.
