NIOSH Approved N95 Dust Mask with Valve

Efficient filtration: N95 is a high protection level mask standard. This type of mask has a filtration efficiency of at least 95% for non oily particles, effectively blocking small particles in the air such as dust, pollen, bacteria, viruses, etc., providing reliable respiratory protection for the wearer. It has a good protective effect in dealing with air pollution, the spread of respiratory infectious diseases such as influenza, and the hazards of dust and smoke in some industrial production environments. The function of the breathing valve: Reduce respiratory resistance: The breathing valve is a one-way valve that allows the wearer to quickly expel gases such as heat, moisture, and carbon dioxide from the mask during exhalation, thereby reducing the pressure inside the mask and reducing the wearer's respiratory resistance. This allows people to breathe more easily when wearing masks, especially for those who need to wear masks for a long time, such as medical staff, construction…
