I-FFP1 imaski
Imaski ye-FFP1 iyimaski encane yokuhlunga kulawa amathathu.
Iphesenti lokuhlunga kwe-aerosol: 80% ubuncane
Izinga lokuvuza kwangaphakathi: umkhawulo ongu-22%
Isetshenziswa kakhulu njengemaski yothuli (isibonelo imisebenzi ye-DIY). Uthuli lungabangela izifo zamaphaphu, njenge-silicosis, i-anthracosis, i-siderosis kanye ne-asbestosis (ikakhulukazi uthuli lwe-silica, amalahle, insimbi yensimbi, i-zinc, i-aluminium noma usimende yizingozi ezivamile zezinhlayiyana).
I-FFP2 imaski
Imaski yobuso ye-FFP2 enevalvu yokukhipha umoya nangaphandle kwayo
Iphesenti lokuhlunga kwe-aerosol: 94% ubuncane
Izinga lokuvuza kwangaphakathi: umkhawulo ongu-8%
Le mask ihlinzeka ngokuvikeleka ezindaweni ezahlukahlukene njengemboni yengilazi, isisekelo, ukwakhiwa, imboni yezemithi kanye nezolimo. Iwamisa ngempumelelo amakhemikhali ayimpuphu. Le maski ingasebenza njengesivikelo kumagciwane okuphefumula afana nomkhuhlane wezinyoni noma isifo sokuphefumula esinamandla esihlobene ne-coronavirus (SARS), kanye namagciwane esifo somoya nesifo sofuba. Kuyafana nesiphefumulo esijwayelekile sase-US N95.
I-FFP3 imaski
I-FFP3 imaski yobuso
Iphesenti lokuhlunga kwe-aerosol: 99% ubuncane
Izinga lokuvuza kwangaphakathi: umkhawulo ongu-2%
Imaski ye-FFP3 iwukuhlunga kakhulu imaski ye-FFP. Ivikela ezinhlayiyeni ezinhle kakhulu ezifana ne-asbestos ne-ceramic. Ayivikeli kumagesi futhi ikakhulukazi ama-oxide e-nitrogen.
