Molao-motheo oa ho sefa oa media oa filthara o ipapisitse le ho kenella ha 'mele, papatso, tlhahlobo le ho thulana ha inertial.
Ho kenella ka 'mele ho bolela hore likaroloana tse emisitsoeng ka metsing li koetsoe ke li-pores tsa mecha ea litaba ea filthara' me li bolokoa holim'a metsi kapa ka hare ho mecha ea litaba. Hangata mecha ea phatlalatso e na le sebopeho se itseng sa pore. Ha metsi a phalla ka har'a lesela la sefe, likaroloana tse ntle li kenngoa hobane boholo ba tsona bo boholo ho feta li-pores.
Adsorption e boetse e phetha karolo ea bohlokoa ts'ebetsong ea ho hloekisa. Bokaholimo ba media oa filthara bo na le matla a itseng a adsorption, a ka adsorb ba bang ba lintho tse qhibilihang ka har'a lintho tse phelang, li-colloid le litšila tse ling, e le hore li amoheloe ke media.
Molao-motheo oa ho hlahloba o tšoana le karolo ea sieve. Mecha ea litaba ea filthara ea boholo bo fapaneng ea likaroloana e na le masoba a boholo bo fapaneng, e ka shebisisang likaroloana tsa boholo bo fapaneng ka metsing, ea thibela litšila tse kholoanyane karolong e kaholimo ea sefa, 'me butle-butle ea phunyeletsa litšila tse nyane ka har'a sekhahla sa sefe.
Ho thulana ha inertial ho bolela hore ha likaroloana tsa metsi li phalla li e-na le inertia e itseng, ha li kopana le li-pores kapa holim'a mecha ea litaba ea filthara, li kheloha tsela ea ho phalla ha metsi ka lebaka la inertia, kahoo li kopana le mecha ea litaba ea filthara le ho amoheloa.
