Izixazululo zomoya ohlanzekile we-FAF zisiza ukuvikela izinqubo ezibucayi zokukhiqiza ezithuthukile, ukuvimbela ukungcoliswa kwe-microbiological kumalebhu ocwaningo, futhi kuqede ukungcola okuthelelanayo okuphuma emoyeni emkhakheni wezokunakekelwa kwempilo. Izihlungi zomoya ze-FAF zihlolwa Nge-IEST Recommended Practice for Testing HEPA Filters (RP-CC034), kuya ku-ISO Standard 29463 kanye ne-EN Standard 1822.
Amakhasimende akuzimboni ezilawulwa kakhulu, anezidingo zekhwalithi eqinile, athemba izihlungi ze-FAF's EPA, HEPA, ne-ULPA. Ezindaweni zokukhiqiza ezifana nemithi, i-semiconductor noma ukucubungula ukudla, noma izinsizakalo ezibalulekile zaselabhorethri, izihlungi zomoya ze-FAF zivikela abantu abathintekayo ezinqubweni futhi ziqinisekise ubuqotho balokho okukhiqizwayo ukuze kuncishiswe izingozi zezimali. Embonini yezokunakekelwa kwempilo, izihlungi zomoya ze-FAF ze-HEPA ziwumgoqo oyinhloko wokuzivikela ekudluliselweni okuthelelanayo ukuze iziguli zesikhungo, abasebenzi, kanye nezivakashi zingaphazanyiswa.
