1. Bvisa zvidimbu zveguruva mumhepo, fambisa neinertial motion kana randomian Brownian motion kana kufamba neimwe simba remumunda. Kana iyo particle motion yarova zvimwe zvinhu, simba revan der Waals rinovapo pakati pezvinhu (molecular and molecular, The force between the molecular group and the molecular group inoita kuti zvimedu zvinamire pamusoro pefaibha. Guruva rinopinda mu filter medium rine mukana mukuru wekurova medium, uye rinonamira parinorova medium. Iyo huruva diki kuita concentration yechimwe nechimwe, guruva rinoita kudhumhana nechikamu chimwe nechimwe nechikamu chimwe nechimwe chinodhumhana mhepo yacho yakagadzikana.
2. Inertia uye Diffusion Particle dust inofamba muinertia mumhepo. Paunenge uchisangana nehutachiona husina kurongeka, mhepo inotenderera inoshandura nzira, uye zvimedu zvakasungwa neinertia, iyo inorova fiber uye inosungirirwa. Iyo yakakura iyo particle, zviri nyore kubata, uye zvirinani mhedzisiro. Duku diki diki rinoshandiswa kuita zvisina tsarukano Brownian kufamba. Izvo zviduku zviduku, zvakanyanya kunyanya kufamba kusina kukwana, mikana yakawanda yekurova zvipingamupinyi uye zviri nani kusefa. Zvimedu zvidiki pane 0.1 micron mumhepo zvinonyanya kushandiswa kuBrownian kufamba, uye zvimedu zvidiki uye kusefa kwakanaka. Zvimedu zvakakura kudarika 0.3 microns zvinonyanya kushandiswa kune inertial motion, uye yakakura iyo zvidimbu, iyo yakakwirira kushanda kwayo. Hazvisi pachena kuti diffusion uye inertia ndiyo yakanyanya kuoma kusefa kunze. Pakuyera kushanda kwepamusoro-soro mafiritsi, inowanzotsanangurwa kuyera guruva rehutano hutsika iyo inonyanya kuoma kuyera.
3. Electrostatic action Nokuda kwechimwe chikonzero, fiber uye zvimedu zvinogona kubhadharwa ne electrostatic effect. Iko kusefa kweiyo electrostatic charged sefa zvinhu inogona kuvandudzwa zvakanyanya. Chikonzero: Magetsi asingachinji anokonzeresa kuti huruva ichinje nzira yayo uye irove chipingamupinyi. Simba remagetsi rinoita kuti huruva inamire zvakanyanya papakati. Zvishandiso zvinogona kutakura static magetsi kwenguva yakareba zvinonziwo "electret" zvinhu. Kupikiswa kwezvinhu mushure memagetsi emagetsi hakuna kuchinjwa, uye filtration effect iri pachena yakagadziridzwa. Magetsi akasimba haaite basa rekuita mukusefa, asi anongoita basa rekubatsira.
4. Kemikari kusefa Masefa emakemikari anonyanya kusarudza adsorb anokuvadza gasi mamorekuru. Kune huwandu hukuru hweasingaoneki micropores mune activated kabhoni zvinhu, iyo ine yakakura adsorption nzvimbo. Mune iyo activated kabhoni yemupunga saizi yezviyo, nzvimbo iri mukati meiyo micropores inodarika gumi masikweya metres. Mushure mekunge mamorekuru emahara asangana neiyo activated kabhoni, anodonhedza kuita mvura mumamicropores uye anoramba ari mumamicropores nekuda kweiyo capillary musimboti, uye mamwe akabatanidzwa nezvinhu. Adsorption pasina yakakosha kemikari kuita kunonzi kushambadza kwemuviri. Mamwe eakabatidzwa kabhoni anorapwa, uye adsorbed zvimedu zvinopindirana nechinhu kuita chinhu chakasimba kana gasi risingakuvadzi, iro rinonzi Huai adsorption. Iyo adsorption kugona kweiyo activated kabhoni panguva yekushandiswa kwezvinhu inoramba ichipera simba, uye kana ichinge yapera simba kune imwe nhanho, iyo sefa inoraswa. Kana ichingori kushambadzira kwemuviri chete, iyo activated kabhoni inogona kuvandudzwa nekudziya kana kupfungaira kubvisa magasi anokuvadza kubva kune activated kabhoni.
