The 3M anti-particulate mask is made of 3M proprietary high-efficiency filter material (polypropylene material), which can meet the requirements of filtration efficiency while maintaining low respiratory resistance. At the same time, it is fixed by headband, ear strap or neck strap, and there are metal nose clips to help the mask and the bridge of the nose fit together.
Benefits of adding an exhalation valve to the mask:
Because wearing a protective mask for a long time will definitely be boring. 3M's proprietary cold flow exhalation valve just solves this problem. When inhaling, the exhalation valve automatically closes to block harmful substances; When exhaling, the valve plate automatically opens, discharging moisture and hot air, reducing exhalation resistance, making exhalation smoother and more comfortable to wear. For example, 3M 9332 anti-particle mask. Features of masks with activated carbon layer;
It is to add a thin layer of activity to the particle protection mask.
Carbon or other gas adsorption materials can reduce some low-concentration gases with unpleasant odor, that is, reduce odor and improve breathing comfort. For example, the odor emitted by corrupt substances (mainly organic substances). When the concentration of odor gas is high enough to be harmful to health, it is necessary to wear a gas mask.
Moreover, 3M pays attention to the adaptability of the anti-particle mask to the user's face, and has developed products specially designed for Asian faces, which can help more people achieve a good fit with the mask. The commonly used masks of 3M are shown in the following figure:
