Kuyi-aifilimu elula ephefumulayo eqinisiweenezimbobo zokuphefumula ezifana nenhlanzi, engasheshisa ukuhamba komoya futhi ixazulule izinkinga eziningi njengokuthola kalula igesi evuthwayo, umswakama, inkohlakalo, isikhunta noma ukujiya, ukuze kuqinisekiswe ukusha kwemikhiqizo yokudla.Ngesikhathi esifanayo, i-fiber eyingqayizivele yokuqinisa i-membrane yokuphefumula ingaphinde ivimbele ulwelwesi ukuthi lungaqhumi futhi lunikeze umthamo ongcono wokuthwala umthwalo.
Ngesikhathi esifanayo, i-ifilimu elula yokuphefumulainezinzuzo zesisindo esilula, ukunwebeka okuhle, ukungena komoya okungama-80%, izindleko eziphansi zokupakisha, kanye nokusebenziseka kabusha.Isetshenziswa kabanzi ekudleni nasesiphuzweni, emikhiqizweni yobisi, ekudleni kwezilwane ezifuywayo, amakhemikhali e-petrochemicals, emikhiqizweni yezemithi, ezimakethe zemikhiqizo yezolimo, izimakethe zengadi, izimakethe zezimbali, njll.
