Now the natural environment is getting worse and worse, people will wear disposable masks when going out, but from what aspect should people buy disposable medical masks?
Dustproof efficiency. The dustproof efficiency of the mask is based on its blocking efficiency against fine dust, especially breathing dust below 2.5 microns. Because this particle size can directly enter the alveoli, it has the greatest impact on human health. The dustproof principle of the gauze mask is mechanical filtration, that is, when the dust hits the gauze, it passes through the multi-layer barrier, which will block some large particles of dust in the emery cloth. Some fine dust, especially those smaller than 2.5 microns, passes through the gauze and enters the respiratory system. A dust mask composed of a filter material, an activated carbon fiber pad or a non-woven fabric, inhalable dust smaller than 2.5 microns passes through the dust mask.
The design of the mask to prevent side leakage is a technical requirement to prevent air from being sucked through the gap between the mask and the human face without filtering. Air, like water, flows in places where there is little resistance. When the shape of the mask is not close to the face, dangerous substances in the air will leak into the person's respiratory tract. So even if you choose the best filter mask. It also does not protect your health. Many foreign laws and standards stipulate that workers should be regularly tested for mask tightness. The purpose is to ensure that workers choose the right mask and wear it in the correct steps.
Comfortable wearing makes workers willing to wear in the workplace and improve work efficiency. Currently, maintenance-free masks abroad do not require cleaning or replacement. When the dust resistance is saturated or the mask is damaged, they will be discarded, which not only ensures the hygiene of the mask, but also saves the time and effort of the worker to maintain the mask. In addition, many masks are arched to ensure a perfect fit with the face and the comfortable space of the nose and mouth.
