Excellent protective performance: High filtration efficiency: FFP3 is one of the higher protection levels in European standards. This type of mask has a very high filtering ability for particulate matter in the air, capable of blocking at least 99% of non oily particles and some oily particles. For various small particles such as dust, pollen, bacteria, viruses, smoke, metal dust, etc., it can provide good protection and effectively reduce the risk of users inhaling harmful substances. It can provide reliable protection in highly polluted environments or work scenarios with extremely high protection requirements. Breathing valve design enhances comfort: Reduce respiratory resistance: The breathing valve is a one-way valve that allows users to quickly expel gases such as heat, moisture, and carbon dioxide from the mask during exhalation, thereby reducing the pressure inside the mask and decreasing respiratory resistance. This allows people to breathe more easily when wearing masks,…
