Zida zosefera zimatanthawuza zida zomwe zili ndi zosefera zina, zomwe zitha kugwiritsidwa ntchito pamachitidwe osiyanasiyana. Makamaka:
1. Munda woyeretsa mpweya: mpweya wa carbon, fiber thonje, galasi la galasi ndi zipangizo zina zingagwiritsidwe ntchito kupanga zowonetsera zosefera kapena zosonkhanitsa fumbi za thumba, zomwe zili zoyenera kuchotsa particles fumbi ndi mpweya woipa m'nyumba ndi kunja.
2. Munda wothira madzi: mitundu yosiyanasiyana ya zinthu zosefera zitha kusankhidwa malinga ndi zofunikira zamadzi, monga mchenga wa quartz, ndodo za carbon activated, nembanemba za ceramic, etc., zomwe zimagwiritsidwa ntchito popangira madzi, kufewetsa ndi kupha tizilombo toyambitsa matenda.
3. Malo opanga mafakitale: M'makampani opanga mankhwala, mankhwala, zakudya ndi zina, mbale zosefera zazinthu zosiyanasiyana zitha kugwiritsidwa ntchito polekanitsa zolimba{1}}zamadzi; Komanso, microporous fyuluta nembanemba angagwiritsidwe ntchito kusanthula ndi kuona zitsanzo zamadzimadzi.
Mwachidule, zipangizo zosefera zimakhala ndi ntchito zosiyanasiyana, ndipo zipangizo zoyenera ndi njira zikhoza kusankhidwa kuti zigwiritsidwe ntchito malinga ndi zosowa zenizeni.
