Byagaragaye ko gushungura igice cya mask byagaragaye ko bitanga uburyo bwiza bwo kwirinda ibitonyanga, aerosole hamwe n’amazi yinjira kandi bigira kashe ikomeye mu kanwa no mu mazuru.
Ubuvuzi / kubaga bitanga inzitizi yihuse hagati yubuhumekero nibidukikije.Imikorere ya mask yo mumaso cyangwa ubuhumekero igenwa nibintu bibiri byingenzi, kuyungurura neza kandi bikwiye (facepiece leakage).Uburyo bwiza bwo kuyungurura bipima uburyo mask yungurura uduce duto mubunini bwihariye, burimo virusi nibindi bice bya subicron, mugihe bikwiranye nuburyo mask cyangwa ubuhumekero birinda kumeneka mumaso.Ukurikije ibipimo bishinzwe ibiryo n'ibiyobyabwenge (FDA) hamwe na filtration effciency, masike yubuvuzi irashobora gushyirwa mubyiciro bitandukanye.Ibi bigabanijwemo ASTM urwego 1, 2 na 3 hashingiwe kumikorere irwanya amazi.Urwego rwa 3 rutanga uburyo bwiza bwo kuyungurura za bagiteri hamwe no kurwanya cyane kwinjiza umubiri.Mu Burayi, masike yubuvuzi yubahiriza ibisabwa nu Burayi Standard EN 14683: 2019.
Nyamara, masike yo kubaga ntigikora neza mugihe ugereranije nubuhumekero.Ubuhumekero bugizwe nibikoresho bikingira bikingira cyangwa ibyuma bisukura ikirere bishobora kubuza uduce duto cyane (<5 μ m) kunyura mu myanya y'ubuhumekero y'umuntu.Ibi bigerwaho haba mugukuraho umwanda cyangwa mugutanga isoko yigenga yo guhumeka.Amazina yabo atandukanye mubihugu bitandukanye.Muri Amerika, Ikigo cy’igihugu gishinzwe umutekano n’ubuzima (NIOSH), kigena imikorere yo kuyungurura imikorere y’ubuhumekero kandi bashyirwa mu byiciro bya N-, R-, na P- kubera kutarwanya amavuta, bimwe birwanya amavuta kandi birwanya cyane .Buri kimwe muri ibyo bice bitatu gifite uburyo butatu bwo kuyungurura kuri 95, 99 na 99.97%, aribyo N95, R95, P95, nibindi. Mu Burayi, ibyiciro byubuhumekero bishobora gushyirwa mubikorwa nko gushungura igice cya masike (gushungura ibice byo mumaso (FFP)), igice cya masike, imbaraga zoguhumeka ikirere (PAPR) na SAR (respirator itanga ikirere).Ukurikije ibipimo by’iburayi, FFP irongera igabanywa muri FFP1, FFP2 na FFP3, ikora neza 80%, 94% na 99% (EN 149: 2001).
