If you want to buy disposable surgical masks, what aspects should ordinary users choose disposable masks from? Next, what should I pay attention to when buying disposable masks?

Now that the epidemic is getting more and more severe, people wear disposable masks when they go out, but when people buy disposable masks, where should they start? The following is a brief introduction to disposable masks, hoping to help everyone.

Dustproof efficiency. The dust-proof efficiency of the mask is based on its fine dust blocking efficiency, especially the inhalable dust below 2.5 microns. Because dust of this size can directly enter the alveoli, it has the greatest impact on human health. The dustproof principle of the gauze mask is mechanical filtration. When the dust hits the gauze, the back layer of the barrier, some large particles of dust are in the sand cloth. Some fine dust, especially dust less than 2.5 microns, can pass through the gauze and enter the respiratory system. In the process of filtering this filter material, a dust-proof mask composed of a filter material activated carbon fiber mat or a non-woven fabric with inhalable dust less than 2.5 microns.

The mask is designed to prevent air from passing through the gap between the mask and the face without being sucked in through the filter. Air is like water, and there is almost no resistance where it flows. When the shape of the mask is not close to the face, dangerous substances in the air will leak into the human respiratory tract. Therefore, even if you choose a mask with the best filter material. It cannot protect your health. Many foreign laws and regulations stipulate that workers should conduct mask sealing tests on a regular basis. The goal is to ensure that workers choose the right masks and wear them in the correct steps.

Wear them comfortably so that workers are happy to persevere in the workplace and increase their productivity. Currently, there is no need to clean or replace foreign maintenance-free masks. When the dustproof performance is saturated or the mask is damaged, they will be discarded. This not only ensures the hygiene of the mask, but also saves the time and energy of workers in maintaining the mask. And many masks are arched, which can ensure a good fit with the shape of the face and maintain a certain amount of space in the mouth and nose for comfort.
