Iimaski zoBuso zeFFP3, ezaziwa ngokuba ziimaski ze-N99, zibonelela ngelona nqanaba liphezulu lokhuseleko.Iimaski zothuli zeFFP3 zinesantya sokuhluza ukuya kuthi ga kwi-99% kwaye zinemigangatho emi-5 yokhuseleko.Zisebenza ngakumbi kunezinye iziphefumlo ezinje nge-N95, FFP2, FFP1 kunye neemaski zotyando.
Iimaski zobuso zeFFP3 zibonelela ngenqanaba eliphezulu lokhuseleko kwiintsholongwane kunye neentsholongwane.Ezi maski zinokuhluza amasuntswana amancinci njenge-0.3 microns.Nangona ezinye iintsholongwane zentsholongwane zincinci kune-microns ze-0.3, i-FFP3 i-respirators elahlayo isakwazi ukukhusela umsebenzisi.Banikezela ngokhuseleko kumntu onxibileyo kwiintsholongwane, iibhaktheriya kunye namanye amasuntswana ayingozi emoyeni.Ezi maski ze-FFP3 ziqhele ukusetyenziswa ngabo basebenza kumzi mveliso wezempilo kwaye ngoku zisetyenziswa luluntu ngokubanzi ukubonelela ngenqanaba eliphezulu lokhuseleko kunezinye iimaski ezilahlwayo.
