Filter media ye filtration system "dusukasi" ye, ani a ka baara be filtration ka baarakɛcogo n’a ka baarakɛcogo yira. Ka kɛɲɛ ni minanw n’a laɲinita ye, a be se ka tilan yɔrɔ saba la:
1. Filtɛri min be kɛ ni filtɛri ye: i n’a fɔ sanbɛrɛ (a bonya 0,5-1,2mm), antrasiti (densugu 1,4-1,8g/cm3), min be se ka kɛ ka fɛnw minɛ minw be se ka yɛlɛma jii furakɛli la;
2. Filtɛri fanga: i n’a fɔ karibɔni min be baara kɛ (a yɔrɔ kɛrɛnkɛrɛnnin yɔrɔ min ka ca ni 1000m2/g ye wala min be bɛn n’o ye), min be kɛ ka fɛɛnw ni dekorizasiyɔn minɛ;
3. Fiber filter media: i n’a fɔ poliyesitɛri fiyɛ (porosité ka ca ni 90 ye walima a be bɛn 90% ma), min bɛnnin lo ni fiɲɛ ye min ka bon.
