Mask e ncha, e latela maemo a KN95, a ts'oanang le litifikeiti tsa American N95 le European FFP2. Sena se bolela hore maske ka 'ngoe a ka sefa liperesente tse 95 tsa likaroloana tse nang le bophara bo boholo ba li-micrometer tse 0.3.

Ho latela ba boholong Shanghai, limaske li na le moea o kenang o phahameng ebile ha li kenelle metsi. Ba apereng nako e telele ba ke ke ba utloa melomo ea bona e fetoha mongobo, ho boletse ba boholong.

Ka har'a mask ho na le lera le lesesaane la nanofiber le ka sefang liperesente tse 95 tsa likaroloana tse nyane joalo ka 0.075 micrometres ka bophara. Coronavirus e ka ba li-micrometer tse 0.1 ka bophara.

Baetsi ba fumane hore mask e ka boloka bokhoni ba eona ba ho sefa bakeng sa lits'ebetso tse 20 kamora ho hloekisoa ka metsi a belang, joala kapa mokelikeli o bolaeang likokoana-hloko tse 84, leha ba khothaletsa hore ba e roetseng ba e sebelise ho feta makhetlo a 10.

Komiti e re matla a tlhahiso a ntse a hola butle butle, ka lebaka la khaello ea basebetsi ba ho roka limaske le thepa e fokolang ea nanometer. Ba boholong ba re e hokahanya phepelo ea lisebelisoa tse tala le ho fana ka thuso ea lichelete ho k'hamphani ea Juchen ho eketsa metjhini e meng ea ho paka.

"Hape ha se bothata hore nanofiber e sebelisoe hape," o boletse joalo. "Ntho ea bohlokoa ea ho hlahisa mask ke ho etsa bonnete ba hore mahlakore ka bobeli a ka koahela sefahleho haufi-ufi, ntle le mapetsong a pakeng."
