Classification Of Masks

1.Classification Of Masks

There are two main categories of masks - medical and non-medical masks. Medical masks are primarily used for medical protection and can be classified into three types - medical protection, medical surgery, and disposable medical masks. Non-medical masks are also known as personal protective masks and can be divided into two types of masks - protective particulate matter masks and daily protection masks. The technical requirements and scopes of application of masks differ based on their intended purposes.

Major mask categories in China

Medical and non-medical masks can be distinguished by their appearance and packaging details. By observing the color, shape, design, and labeling of the mask packaging, one can easily identify if it is a medical-grade or non-medical mask. Medical masks are typically blue or green in color with an intricate design. They are also labeled with information such as the manufacturer's name, product code, and expiry date. On the other hand, non-medical masks come in a variety of colors and designs and may not have any labeling or packaging information. Therefore, it is essential to pay attention to the appearance and packaging information when selecting the appropriate mask for use.

The issue of filter valves in masks has been resolved through the use of specific valve filters. However, it should be noted that masks equipped with filter valves are generally not medical masks. The Chinese Medical Protective Mask Standard GB 19803-2010 strictly prohibits masks with exhalation valves. This measure is in place to prevent droplets, microorganisms, and other harmful contaminants from escaping through the valve and potentially harming others. On the other hand, civil masks may have exhalation valves installed. By reducing exhalation resistance, the valve can enhance the operator's ability to perform their work for an extended period.

When buying masks through official channels, it's important to look for certain information on the packaging. The package should clearly display the product name, the implemented standards, and the level of protection offered by the mask. This information can also be used to differentiate between different types of masks. For instance, masks labeled as "Medical" or "Surgical" and with "Medical" in English are generally considered to be medical-grade masks. To ensure the safety and effectiveness of the masks, it's crucial to pay attention to these details when purchasing them.

Medical and non-medical masks are distinguished by applicable standards. It is important to note that certain standards apply specifically to medical masks, while others are intended for non-medical use. Therefore, when choosing a mask, it is necessary to understand the applicable standard to ensure that it meets the intended use case.

Medical masks must adhere to varying standards and certification requirements depending on the country or region they are produced and sold in. To determine the applicable standards for a specific product, it is crucial to identify the country or region of importation. Businesses and individuals must acquire test reports or certification to ensure the product meets the necessary standards for the given region. By adhering to these guidelines, medical masks can effectively provide the necessary protection for both wearers and those around them.
