What are the characteristics of surgical mask, FFP mask or fabric mask, and in particular, who are they aimed at?
By definition, the mask is a screen set in front of the mouth to absorb potentially contaminated droplets and avoid contamination.
What's the difference between everyone?
Anti projection surgical mask This is to avoid people wearing it expired, it does not protect the people wearing it, but to protect the people around them. Therefore, it is recommended that when the patient is ill, or when people feel the early symptoms of covid-19, it is recommended to avoid infecting the people contacted. Therefore, when a family member is infected, it can also be used at home. The mask has a life span of 3 to 4 hours and is disposable.
FFP mask for filtering facial parts It is also a one-time use, although it takes longer (8 hours). On the contrary, unlike surgical masks, it operates in two directions, protecting mask carriers from the risk of inhaling the droplets carrying the virus, while preventing the carrier from projecting the droplets into the surrounding area.
Washable fabric mask It's a Barrier maskDrop projection inhibitors for retention of certified disposable masks in medical media. Based on the AFNOR NF surgical mask standard of 14683, the state has reduced the standard ("hospital requirements") in order to be able to produce more basic masks for the entire population. There are two categories that need to be distinguished: the first category of masks ("UNS 1") is the barrier mask of people in contact with the public ("servers, tellers, etc.), and the second category is more suitable for companies that have little contact with customers.
In order to cope with the current epidemic shortage, disposable masks (surgical or FFP type) are mainly used in the medical field; tissue masks. Logically, these measures are a logical complement to the obstacle measures, and as can be seen from many European and Asian countries, they are mandatory and effective, especially at the next stage. However, to be effective, it must be used effectively to avoid, in turn, carrying more viruses than they reject.
