1 Basic classification and subdivision of masks
The use of anti-coronavirus masks can be divided into two categories: medical masks
and non-medical masks. As the name implies, anti-coronavirus masks and medical masks are mainly used for medical protection, and can be subdivided into three types: medical protection, medical surgery, and disposable medical; non-medical masks are also called personal protective masks, which can be used according to their application scenarios. It can be subdivided into anti-particle and daily protection. Masks for different purposes have different technical requirements and different scopes of application.
2Using appearance and packaging information to distinguish medical/non-medical masks of anti-coronavirus masks
Distinguish by mask structure
Recognized by the filter valve. Masks with filter valves are generally not medical masks. For example, Article 4.3 of the Chinese Medical Protective Mask Standard GB 19803-2010 clearly stipulates that “masks should not have an exhalation valve”, so as to prevent droplets and microorganisms from exhaling through the exhalation valve, thereby harming others. Civil masks are allowed to have an exhalation valve, and the exhalation resistance can be reduced through the exhalation valve, thereby facilitating long-term work of the operator.
The smallest unit packaging of mask products sold through formal channels should have information such as the name of the product, the implemented standard, and the level of protection. The information expressed by these businesses can be used as a distinguishing point. For example, if the product name has the words "medical" or "surgical" or "Medical" in English, it can generally be judged as a medical mask.
3 Applicable standards distinguish anti-coronavirus masks, medical/non-medical masks
Medical masks are subject to different standards and certification requirements in different countries/regions. Enterprises and individuals can distinguish according to the country/region where the product is imported and the applicable standards of the product. The applicable standards and certification information of the product can be provided from the outer packaging of the product or the manufacturer. Obtain the test report or certificate.
4 Distinguish through government registration control information
Since anti-coronavirus masks and medical masks are registered or controlled in accordance with medical devices in most countries or regions, consumers can further distinguish through relevant registration and control information.
