Chao Mei ke moetsi ea ka sehloohong le morekisi oa li-respirators tsa boleng bo holimo tse ntle le limaske tse sireletsang. Lihlahisoa tsa rona li etselitsoe ho fana ka tšireletso e phahameng ho basebetsi ba indasteri, litsebi tsa bongaka le batho ba letsatsi le letsatsi.
Ho Chao Mei, re fana ka lihlahisoa tse fapaneng, ho kenyeletsoa li-respirators tse sefang likarolo tse ngata, li-respirators tsa KN95, limaske tsa FFP2, limaske tsa bongaka tse lahloang, le tse ling. Lihlahisoa tsa rona li entsoe ka maemo a holimo ka ho fetisisa 'me li netefalitsoe bakeng sa polokeho le katleho.
E 'ngoe ea lihlahisoa tsa rona tsa bohlokoa ke mochine o phefumolohang oa khatello e ntle, e thusang ho etsa bonnete ba hore moea o hloekileng o lula ho ea o apereng. Theknoloji ena e bohlokoa bakeng sa ho sireletsa khahlanong le litšila tse tsamaisoang ke moea le ho boloka tikoloho e phefumolohang e phetseng hantle libakeng tse kotsi.
Li-respirators tsa rona tse ntle tsa khatello li loketse ho sebelisoa maemong a indasteri, litsing tsa bongaka, le maemo a letsatsi le letsatsi moo boleng ba moea bo ka senyehang. Ka li-respirators tse ntle tsa Chao Mei, u ka ba le khotso ea kelello ka ho tseba hore u sirelelitsoe khahlanong le likaroloana tse kotsi le litšila.
Ntle le li-respirators tse ntle tsa khatello, Chao Mei e boetse e fana ka limaske tse fapaneng tse sireletsang bakeng sa lits'ebetso tse fapaneng. Ho tloha ho limaske tsa mosebetsi oa indasteri ho isa ho limaske tsa PM2.5 tsa sechaba, re u koahetse litlhoko tsohle tsa hau tsa ts'ireletso ea phefumoloho. Li-mask tsa rona li phutholohile ho roala, li phefumoloha habonolo, 'me li fana ka katleho e ntle ea ho sefa.
Ha ho tluoa tabeng ea ho itšireletsa le baratuoa ba hau, tšepa Chao Mei bakeng sa li-respirators tsa boleng bo holimo tse ntle le limaske tse sireletsang. Etela sebaka sa rona sa Marang-rang kajeno ho ithuta haholoanyane ka lihlahisoa tsa rona le hore na li ka u thusa joang hore u lule u sireletsehile tikolohong efe kapa efe.
