Ifu y’ibigori y’ibigori y’amahasa ni ubwoko bw’ibikoresho vy’inkomoko y’ibifungurwa bifise igipimo kinini c’ikoreshwa ry’ikoreshwa ryaronswe mu gusenya ibigori bitagiramwo ibinure, kuvanga n’igice kinaka c’amazi, hanyuma bikagira uburyo bwo gufungurira.
Mu gihe c’ubushuhe bwinshi be n’umuvuduko munini, ifu y’ibigori ipfutse iguma ifata inguvu maze igaca ihindura ubukonje buri mu nzitiro z’ibigori, maze igaca ija ku nguvu mu bihimba vy’ibigori. Imbere y’uko ishika ku gice c’ugutuma ibintu bimwe bimwe bishika, buhoro buhoro ifu y’ibigori irahinduka kuva ku nzira ikomeye gushika ku nzira y’amazi. Igikoko ca zein zein kirabandanya igikorwa caco co gusesa poroteyine mu gice c’uguhinduranya, kandi gikomeza gusohoka. Iyo umuntu ahuye n'ugukonjesha bukwi na bukwi, iyo molecule y'amazi yashizwe mu molecule ya proteine iragwira cane, iratera umwuka, kandi "iturika". Ivyo bikoresho biyikikuje biraheza igikorwa co gushaza, kandi muri ico gihe nyene bituma ico kintu gihinduka ikintu kitagiramwo ibintu gifise imirongo myinshi y’ibigori, ivyo bikaba bizoba ifu y’ibigori ipfutse inyuma yo gukonjesha no gusenyuka. Ifu y’ibigori y’ibigori ni umuhondo, ifu microporous ifu y’amabuye y’agaciro yitwa microporous n’akamoto karimwo.
Ingaruka y’ifu y’ibigori ipfutse mu gutunganya ibifungurwa ni ugufatanya. Nk’akarorero, ibifungurwa vy’amafi canke ibindi bifungurwa bikoreshwa mu gukura kw’amazi akenshi vyongerwako n’ifu y’ibigori ifise ibinure. Kubera ko ifu y’ibigori ifise ibinure ifise ubushobozi bwo kwifatanya neza n’ubushobozi bwo guhangana n’ifu mu mazi, igiciro c’ifu y’ibigori y’agaciro kanini ipfutse mu mazi yo mu mazi.
