Medical Masks Have Become A Favorite Item For Many People, So Do You Know That Medical Masks Can Prevent Dust?

Haze has a great impact on people. Every time there are haze days, there will be a lot of respiratory patients. In order to avoid respiratory diseases, people will choose to use masks. Medical masks have become a favorite item for many people. , so do you know that medical masks can prevent dust? Let's talk about it in detail.

Types and characteristics of medical masks:

As the name suggests, medical masks are mainly used by medical staff at work, and can effectively protect against certain germ particles in the medical process.

Medical masks are mainly divided into the following three categories:

1. Disposable medical masks, also known as medical-surgical masks, are usually used in surgery and are blue flat masks. Disposable medical masks are divided into three layers. The outer layer is used to prevent blood or saliva from splashing. The middle layer mainly filters toxic substances such as germs.

2. Gauze masks, with a market share of 50%, can usually be divided into six layers, twelve layers, and eighteen layers. The gauze masks are all white, made of pure cotton embryo cloth, which has been degreased and bleached. The mask is soft, odorless, tasteless, and free of impurities. After each use, it can be washed with soap and soaked in disinfectant for disinfection and then reused.

3. Medical protective masks, the most professional protective masks in the medical industry, are the most commonly used protective masks for respiratory infectious diseases and are widely used during the protection of SARS, avian influenza virus, and the current Ebola virus. Medical protective masks are generally divided into three layers. The inner layer is made of non-woven fabric, the middle layer is a high-efficiency electrostatic melt-blown layer, and the outer layer is an ultra-thin polypropylene melt-blown layer. Medical protective masks have remarkable anti-virus and germ-proof performance. Most of the masks are maintenance-free and cannot be reused after cleaning.

So, after understanding the three different types of medical masks, let's talk about whether they can prevent pm2.5.

1. Disposable medical masks cannot prevent PM2.5. This mask can effectively filter dust particles larger than 4 microns in diameter and can protect against blood bacteria. At present, the main domestic manufacturing standard is YY0469-2011 "Technical Requirements for Medical-Surgical Masks";

2. The gauze mask is even less capable of preventing PM2.5. It can only protect large-diameter particles. It is the protective mask with the worst protective filtering effect among the three types of medical masks. There is currently no relevant testing standard in China;

3. Medical protective masks can effectively prevent PM2.5. The masks meet the GB19083-2010 "Technical Requirements for Medical Protective Masks" standard, and can effectively filter dust particles with a diameter of fewer than 0.3 microns and pathogenic microorganisms.

In addition, the best-selling medical protective mask on the market is the 3M1860 medical protective mask. Does this mask conform to the US NIOSH? N95 mask standard and the dust filtering efficiency is the same as that of the N95 industrial dust mask, but this mask does not have an exhalation valve. High resistance, is generally not suitable for children, the elderly, and people with respiratory diseases.

Through the above introduction, do you already know that there is an answer to the question of whether medical masks can prevent dust? Medical masks are divided into three categories. Different categories and materials have different protective effects. Disposable masks and medical protective masks have better dust-proof effects, especially protective masks can prevent PM2.5 very well, so choose When choosing a mask, be careful not to choose the wrong one.
