Kazhinji, kuchena kwemhepo kunoenderana nefirita remhepo rekupedzisira, iro rinodzivirirwa nemafirita ese emhepo epamberi. Zvinhu zvakasiyana-siyana zvinofanirwa kutariswa pakusarudza mafirita emhepo. Heano mamwe mazano:
1.Zvichienderana nezvinodiwa pakuchenesa mukati meimba, sarudza kushanda kwesefa rekupedzisira remhepo. Unofanirawo kuve nechokwadi chekuti huwandu hwemafirita emhepo aidiwa uye kushanda kwawo pakusefa. Kana imba ichida kucheneswa kwakazara, unogona kusarudza sefa rekutanga. Pakuchenesa kwepakati, unofanirawo kusarudza sefa rinoshandisa simba repakati, pamusoro perekutanga. Saka, mafirita ekutanga, epakati, uye anoshanda zvakanyanya anofanira kushandiswa kuzadzisa zvinodiwa pakuchenesa kwakachena zvakanyanya. Unofanira kuronga mafirita iwayo zvine musoro.
2.Sarudza guruva riri mumhepo yekunze. Sefa yemhepo inobvisa guruva kubva mumhepo yekunze iro rinozopinda mukati meimba gare gare. Kunyanya pakusefa kwematanho akawanda, unofanirwa kusarudza sefa zvichienderana nenzvimbo yekushandisa, mutengo wezvikamu zvekuchengetedza, kushandiswa kwesimba, kugadzirisa, nezvimwewo.
3.Sarudza maparamita efirita yemhepo. Maparamita aya anosanganisira kushanda zvakanaka kwefirita, kuramba, mwero wekupinda, kugona kubata guruva, nezvimwewo. Nepose pazvinogoneka, unofanira kusarudza firiji yemhepo ine mutengo unonzwisisika, iyo inozivikanwa nekushanda zvakanaka, kuramba kwakaderera, kugona kubata guruva kukuru, kumhanya kwekusefa kuri pakati nepakati, kugona kubata mhepo zvakanyanya, uye kuisa zviri nyore.
4.Ongorora hunhu hwemhepo ine guruva. Hunhu hwacho hunosanganisira tembiricha, hunyoro, uye huwandu hweacid base kana organic solvent. Mamwe mafirita emhepo anoshandiswa pakupisa kwakanyanya, nepo mamwe achingoshandiswa chete munzvimbo ine tembiricha yakajairika uye hunyoro. Pamusoro pezvo, huwandu hweacid-base kana organic solvent huchakanganisa mashandiro emhepo filter.
