What is the function of FFP3 mask?
The FFP3 mask protects your respiratory tract from potential sources of infection and, if you are infected, those around you. FFP3 masks are considered an important part of personal protective equipment because they help reduce the spread of disease. If a person is infected and develops symptoms of COVID-19, respiratory droplets inevitably spread when they cough, sneeze, or talk, eventually being inhaled by healthy people in the air, on objects or surfaces. A healthy person comes into contact with contaminated air, objects, surfaces, and in contact with their respiratory tract, which is why they become infected.
How long can the FFP3 mask be used?
FFP3 mask is generally recommended not to exceed 4 hours. FFP3 mask is not recommended to be worn for a long time. It is generally recommended to replace it every 2-4 hours. If you wear a used disposable mask for too long, more than 4 hours, a large amount of particles in the air will be adsorbed on the outside of the mask, thereby blocking The gaps in the filter material of the mask will not only reduce the filtering efficiency of the mask, but also increase the breathing resistance. Over time, it will affect the human nasal mucosa and reduce the original physiological function of the nasal cavity. Because the FFP3 mask is used for a long time, the large particles will be blocked on the surface of the mask or the ultra-fine particles will block the gaps of the filter material of the mask, resulting in a decrease in the filtration efficiency of the FFP3 mask and an increase in respiratory resistance. Medical disposable masks are not recommended for long-term use.
What is the role of FFP3 mask on the epidemic?
FFP3 mask is the most commonly used mask for medical staff. Common surgical masks can be selected for contact with patients with common infections, such as colds, pneumonia, treatment of common bacterial infection wounds, and surgical operations. Compared with ordinary masks, this kind of mask has better sealing performance. The biggest difference from ordinary medical masks is that it is impermeable. The particle filtration must be ≥30%. It is very effective in blocking the new coronavirus and is recommended. FFP3 mask is suitable for use in epidemic areas, hospitals and other places with dense crowds, seeing a doctor, etc. It is the most practical mask. In addition to high-risk positions in the hospital, staff in other positions can wear this mask for protection.
