Ke aila ka mea lawe o kekahi mau ʻāpana, a hoʻopili ʻia kēia mau mea i ka lole uila ʻole i ulana ʻia, e hoʻemi ʻia nā waiwai uila, a komo ka lepo maikaʻi. No laila, pono ka kānana kānana no ka pale ʻana i ka ʻaila a me ke kalaea i lalo i ka hana electrostatic kūikawā e pale ai i ka fineness. Ke kumu o ka lepo. No laila ua mahele ʻia kēlā me kēia moʻo i nā pae he 3: 95%, 99%, 99.97% (ʻo ia hoʻi, 95, 99, 100), no laila aia he 9 mau mahele liʻiliʻi o nā mea kānana.

Mai ka manaʻo o ke kālaikaola o ke kanaka, ikaika loa ka holo ʻana o ke koko i ka mucosa ihal, ʻo nā kahawai i ka ihu ihu he mea ʻino loa ia, a ʻo nā lauoho ihu ke ʻano he "pale". Ke omo ʻia ka ea i loko o nā puka ihu, hana ka airflow i vortex ma ke kahawai tortuous, kahi e wela ai ke ea i omo ʻia i loko o ka lua ihu. Ua hōʻike ʻia kekahi mau hoʻokolohua ʻole i ka honu ʻana o ka ea anuanu ma minus 7 ʻ ° C i ka huki ʻana i ka puka o ke ihu, ua hoʻomāloo ka nui o ka ea i ka 28.8Â ° C, kahi kokoke loa i ka mahana o ke kino o ke kanaka. Inā komo ʻoe i kahi pale maka no ka manawa lōʻihi, e palupalu ka nasal mucosa a lilo i ka hana physiological kumu o ka hū ihu, no laila ʻaʻole hiki iā ʻoe ke komo i kahi pale maka no ka manawa lōʻihi.
