 A face mask with code 3M FFP2 protects against solid and liquid irritating aerosols. Minimum filter efficiency of 92%. The Series combines ground-breaking ideas, technologies and materials in a convenient three-panel, flat-fold design. … Hygienic packaging: helps protect the respirator from contamination before use, also allows practical storage and dispensing in the workplace. Can FFP2 masks be cleaned and reused? FFP2 masks can be bought in pharmacies, drugstores and on the internet.
Difference between ffp2 and ffp3 masks
3M mask FFP2 masks
have a minimum of 94% filtration percentage whilst 3M mask FFP3 masks are the most filtering
mask of the FFP. With a minimum filtration percentage of 99%, they protect
against very fine particles such as asbestos. ... 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.
