The number after the letter indicates the percentage of filtration of suspended particles In the USA, respirators must meet NIOSH (National Institute for Occupational Safety and Health) standards. Within this standard, there are several classes of respirators, N, R, and P, depending on the degree of oil resistance, not relevant to COVID-19. The number after the letter indicates the percentage of filtration of suspended particles. N95 and FFP2 are approximately equivalent and are the minimum advised for working with aerosol producing procedures with COVID-19 positive patients. Whilst the virus itself measures 0.06 μm, it will usually be associated with water increasing its size in the acute aerosol production stages.

Advantages of ffp2 masks.

FFP2-mask fulfil a set of stricter protective norms. They protect the person wearing them, as > 95% of particles and droplets are held back when inhaling. FFP2-masks also effectively protect the environment as long as there is no exhaling valve. In contrast, masks with an exhaling valve let exhaled air pass out unfiltered, with contamination of the immediate environment

How ffp2 help in reducing Covid 19.

FFP2 masks are recommended to prevent onward transmission in the general population in public areas, particularly where distancing is not possible, and in areas of community transmission. This could include the school grounds in some situations. Masks may help to protect others, because wearers may be infected before symptoms of illness appear. The policy on wearing a mask or face covering should be in line with national or local guidelines. Where used, masks should be worn, cared for and disposed of properly.

FFP2 With valve mask with vents or exhalation valves are not advised because they allow unfiltered breath to escape the mask. Masks with vents or exhalation valves are not advised because they allow unfiltered breath to escape the mask.

COVID-19 can be spread directly by droplets from coughs, sneezes and speaking. These droplets can also be picked up from surfaces by touch and subsequently from touching the face. That is why hand hygiene is so important in controlling the infection.

Evidence shows a face covering can help in reducing the spread of droplets and therefore potentially infecting others, and could help to reduce the spread of infection as lockdown measures start to be lifted. It is important people refrain from touching their face covering when wearing it, where possible, to avoid hand to mask transmission of the virus.
