How To Choose A Mask

Dust blocking efficiency

The dust blocking efficiency of the mask is based on its blocking efficiency against fine dust, especially respiratory dust below 2.5 microns. Because dust of this particle size can directly enter the alveoli, it has the greatest impact on human health. The dust blocking principle of gauze masks is mechanical filtration, that is, when the dust collides with the gauze, some large particles of dust are blocked in the sand cloth through layers of barriers. Some fine dust, especially dust smaller than 2.5 microns, it will pass through the mesh of the gauze and enter the respiratory system. Dust masks are composed of activated carbon fiber felt pads or non-woven fabrics, and those respirable dust smaller than 2.5 microns are blocked in the process of passing through this filter material, which plays the role of filtering air.

Degree of closeness

The anti-side leakage design of the mask is to prevent the air from being inhaled through the gap between the mask and the human face without being inhaled through filtering. Air is like water flow, where there is less resistance, it flows first. When the shape of the mask does not fit closely with the face, the dangerous substances in the air will leak in from the non-contact and enter the respiratory tract of the person. So, even if you choose a mask with the best filter material. Nor can your health be guaranteed. Many foreign regulations and standards stipulate that workers should regularly test the tightness of masks. The purpose is to ensure that workers choose the right size mask and wear the mask according to the correct steps.

Comfortable to wear

In this way, workers will be willing to stick to wearing them in the workplace and improve their work efficiency. The current foreign maintenance-free masks do not need to be cleaned or replaced. When the dust resistance is saturated or the masks are damaged, they are discarded, which not only ensures the hygiene of the masks but also saves the time and energy of workers to maintain the masks. Moreover, many masks adopt an arched shape, which can not only ensure a good fit with the shape of the face but also retain a certain space at the mouth and nose, making it comfortable to wear.
