A na nka sebelisa mask ho e-na le mask? A na nka sebelisa mask a lahliloeng hape?)
Mathoasong a Pulungoana, ofisiri e kholo ea bophelo bo botle ba sechaba sa Canada, Dr. Theresa Tam, o ile a nchafatsa likhothaletso tsa hae mabapi le limaske tseo e seng tsa bongaka. Hona joale o khothaletsa hore limaske bonyane li be le mekhahlelo e meraro ho fapana le tse peli, le hore karolo ea boraro e be lesela le sefang joalo ka polypropylene e seng lohiloeng. Leha ho le joalo, o re ha ho na lebaka la ho lahla likarolo tse peli tsa mask.
Health Canada e na le litaelo tsa ho etsa mask a ply-ply tse tharo mme e re u ka fumana lisebelisoa tse latelang tse sa lohiloeng tsa polypropylene:
Li-mask tsa N95 le tsa bongaka li sebelisa thepa e sa lohiloeng ea polypropylene. Ha ea lokela ho lahleheloa ke fiber, ho bolela James Scott, moprofesa le motsamaisi oa bophelo bo botle ba mosebetsi le tikoloho Univesithing ea Toronto's Dalla Lana School of Public Health.

O boetse a re limaske tsa N95 li ka sebelisoa hape ho fihla makhetlo a 10 ntle le ho senya lisebelisoa tsa sefa haeba li hloekisoa ka hydrogen peroxide e bonolo lipakeng tsa ts'ebeliso. Leha ho le joalo, o ne a sa tsebe hore na li-polypropylene nonwovens li tla tšoarella joang ka mor'a ho hlatsoa khafetsa lapeng.
Ka nako e ts'oanang, lintho tse ling tse ngata malapeng a rona li entsoe ka thepa ea maiketsetso, 'me mohlomong u ne u ntse u hema likhoele tse ngata tsa polypropylene ho tloha lerōleng le u potolohileng. Phuputso ea 2016 e entsoeng ke bafuputsi ba Mafora e fumane hore 33% ea likhoele tse moeeng o ka hare ke tsa maiketsetso, 'me polypropylene ke eona ntho e ka sehloohong.
Leha ho le joalo, ho na le litlaleho tsa hore basebetsi ba masela ba pepesehetseng likhoele tse ngata tsa maiketsetso ba ka baka mathata a matšoafo.

Haeba u lumela hore morekisi o etsa lipolelo tse fosahetseng kapa tse khelosang ka lihlahisoa tsa hae, u ka tlaleha ho Bureau ka ho sebelisa foromo ena ea inthaneteng.
Ee, ho arohana sechabeng ho ntse ho hlokahala kaha limaske tse tloaelehileng tsa bongaka le tseo e seng tsa bongaka li fokotsa feela palo ea likaroloana tse nkong le molomong.

Empa ho sa tsotellehe hore na u roala maske kapa che, ha u le sebaka se seholo, tšireletso e kholoanyane. Ho ea ka Kumar, haeba sebaka se pakeng tsa hao le motho e mong se imena habeli, palo ea likokoana-hloko tse fihlang ho uena e fokotseha ka makhetlo a ka bang robeli. Ho roala maske ho etsa hore likaroloana tse kholoanyane, tse tšoaetsanoang haholoanyane li lule haufi le motho ea roalang maske ea tšoaelitsoeng pele li fihla ho motho e mong.
Martin Fisher, motlatsi oa moprofesa oa k'hemistri Univesithing ea Duke e Durham, North Carolina, ea ithutileng mokhoa oa ho lekanya katleho ea limaske tse fapaneng, o itse ha ho na karabo e hlakileng.
