Dustproof efficiency. The dust-proof 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 a greater impact on human health. The dustproof principle of the gauze mask is mechanical filtration, that is, when dust impacts the gauze, it passes through a multi-layer barrier to block some large particles of dust in the emery cloth. Some fine dust, especially those smaller than 2.5 microns, pass through the gauze and enter the respiratory system. A dust-proof mask composed of filter materials, activated carbon fiber mats or non-woven fabrics, through which inhalable dust less than 2.5 microns passes.

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 face without filtering. Like water, air flows in places where there is almost no resistance. When the shape of the mask is not close to the face, dangerous substances in the air will leak into the human respiratory tract. So even if you choose a good filter mask. It also does not protect your health. Many foreign regulations and standards stipulate that workers should be tested for the tightness of their masks on a regular basis. The goal is to ensure that workers choose the right masks and wear them in the correct steps.

It is comfortable to wear, so that workers are willing to wear it in the workplace and improve work efficiency. Currently, foreign maintenance-free masks do not need to be cleaned or replaced. 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 energy of workers to maintain the mask. In addition, many masks are arched to ensure a perfect fit with the shape of the face and the comfortable space of the nose and mouth.
