Kawirikawiri, kuyera kwa mpweya kumadalira fyuluta yomaliza ya mpweya, yomwe imatetezedwa ndi zosefera zonse zakutsogolo. Zinthu zosiyanasiyana ziyenera kuganiziridwa posankha zosefera za mpweya. Nazi mfundo zina pansipa:
1.Mogwirizana ndi miyezo yoyeretsera mpweya yomwe ikufunika mkati, dziwani momwe fyuluta yomaliza ya mpweya imagwirira ntchito. Muyeneranso kuonetsetsa kuti fyuluta ya mpweya yomwe ikufunika ndi momwe imasefera. Ngati fyuluta yamkati ikufunika kuyeretsa kwathunthu, mutha kusankha fyuluta yoyamba. Pa kuyeretsa kwapakati, muyeneranso kusankha fyuluta yoyeretsera mpweya, kuwonjezera pa fyuluta yoyamba. Chifukwa chake, fyuluta yoyamba, yapakati, komanso yogwira ntchito bwino iyenera kugwiritsidwa ntchito kuti ikwaniritse zofunikira pakuyeretsa koyera kwambiri. Muyenera kukonza fyulutayo mwanzeru.
2.Dziwani kuchuluka kwa fumbi mu mpweya wakunja. Fyuluta ya mpweya imachotsa fumbi mu mpweya wakunja lomwe lidzalowe mkati pambuyo pake. Makamaka pa njira zosefera zomwe zimagwiritsidwa ntchito m'magawo ambiri, muyenera kusankha fyulutayo malinga ndi malo ogwiritsira ntchito, mtengo wa zida zosinthira, mphamvu zomwe zimagwiritsidwa ntchito, kukonza, ndi zina zotero.
3.Dziwani magawo a fyuluta ya mpweya. Magawowa akuphatikizapo kusefa bwino, kukana, kuchuluka kwa kulowa, mphamvu yogwira fumbi, ndi zina zotero. Momwe mungathere, muyenera kusankha fyuluta ya mpweya yokwera mtengo, yomwe imadziwika ndi mphamvu yogwira ntchito bwino, kukana kochepa, mphamvu yogwira fumbi lalikulu, liwiro losefera pang'ono, mphamvu yogwira mphepo yambiri, komanso kuyika kosavuta.
4.Unikani mawonekedwe a mpweya womwe uli ndi fumbi. Makhalidwe ake ndi kutentha, chinyezi, ndi kuchuluka kwa acid base kapena organic solvent. Ma filter ena a mpweya amagwiritsidwa ntchito kutentha kwambiri, pomwe ena angagwiritsidwe ntchito kokha pamalo omwe kutentha ndi chinyezi chabwinobwino. Kuphatikiza apo, kuchuluka kwa acid-base kapena organic solvent kudzakhudza magwiridwe antchito a fyuluta ya mpweya.
