Air pollution is a serious social problem in China today. In addition to the well-known PM2.5, there are other pollutions such as dust, bacteria, pollen, and automobile exhaust that threaten our health. Masks are currently the only effective means to combat outdoor air pollution. The disposable 3-layer non-woven medical mask can filter particles in the air, block droplets and secretions. Help you and your family stay away from pollution. So what brand of disposable mask is good? How to choose?
First, the dust barrier efficiency of the mask. The dust-blocking efficiency of the mask is based on its barrier efficiency against fine dust, especially for respiratory dust below 5 microns. Because this particle size of dust can directly enter the alveoli, it has the greatest impact on human health. The general gauze mask, the dust-proof principle is mechanical filtration, that is, when the dust collides with the gauze, through the layer-by-layer barrier, some large particles of dust are blocked in the sand cloth. However, some fine dust, especially dust less than 5 microns, will pass through the mesh of the gauze and enter the respiratory system. So what brand of disposable mask is good? There are some dust masks in foreign countries. The filter material is composed of fibers filled with permanent static electricity. Those less than 5 micrometers of respirable dust are attracted by static electricity during the process of passing through the filter material. Dust, really plays a role in dust prevention.
Second, the degree of adhesion between the mask and the shape of the face. The air is like a stream of water. Where the resistance is small, it flows first. When the shape of the mask is not close to the face, the dangerous objects in the air will leak from the intimate place and enter the human respiratory tract. Then, even if you choose a good mask for the filter material. Nor can you protect your health. Many foreign regulations now stipulate that workers should conduct mask adhesion tests on a regular basis. The purpose is to ensure that the worker chooses a suitable mask and wears the mask in the correct order.
Third, wear comfortably. Requires low respiratory resistance, light weight, hygienic and easy maintenance. This way workers will be willing to wear and improve their work efficiency in the workplace. The maintenance-free masks in foreign countries do not need to be cleaned or replaced. When the dust is saturated or the mask is damaged, it is discarded. This not only ensures the hygiene of the mask but also saves the time and effort of the worker to maintain the mask. Moreover, many masks have an arch shape, which can ensure a good adhesion to the shape of the face and a certain space at the nose and mouth, and is comfortable to wear.
The above is a good introduction to what brand of disposable masks, I hope to help everyone.
