Kusindikiza kwa nyumba zamakono kukukhala bwino komanso bwino, zomwe zimapangitsa kuti pakhale kuyendayenda kovuta kwa mpweya wamkati ndi wakunja.Kwa nthawi yayitali, zikhudza kwambiri mpweya wamkati, makamaka mpweya woipa wamkati sungathe kuthetsedwa, monga formaldehyde ndi benzene, ma virus ndi mabakiteriya ndi zina zambiri, zidzakhudza kwambiri thanzi la anthu.

Komanso, ngati anthu amakhala m'dera ndi osindikizidwa, ndende ya mpweya woipa m'chipinda adzakhala ndithu mkulu patapita nthawi yaitali, amenenso adzachititsa anthu kukhala omasuka, kuchititsa nseru, mutu etc. Mu milandu kwambiri, kukalamba msanga. ndipo matenda a mtima akhoza kuchitika.Choncho, khalidwe la mpweya ndilofunika kwambiri kwa ife, ndipo njira yowongoka komanso yothandiza kwambiri yopititsira patsogolo mpweya wa m'nyumba ndi mpweya wabwino, womwenso ndi njira yofunikira yopititsira patsogolo malo okhalamo komanso moyo wabwino.

Ntchito zisanu zofunika kwambiri za makina opangira mpweya wabwino zimathandiza ogwiritsa ntchito kusangalala ndi moyo wabwino komanso kupuma mpweya wabwino momasuka.

1.Ntchito ya mpweya wabwino, ndiye ntchito yofunika kwambiri, imatha kupereka mpweya wabwino maola 24 patsiku, masiku 365 pachaka, kupereka mpweya wabwino m'nyumba mosalekeza, mutha kusangalala ndi mpweya wabwino.chilengedwempweya wabwino popanda kutsegula mazenera, ndikukwaniritsa zosowa za thupi la munthu.

2.Ntchito yobwezeretsa kutentha, yomwe imasinthanitsa mphamvu pakati pa mpweya wakunja ndi wamkati, mpweya woipitsidwa umatulutsidwa, komakutentha ndimphamvu imakhalabe m'nyumba.Mwanjira imeneyi, mpweya wabwino wakunja umalowa nthawi yomweyo pafupi ndi kutentha kwamkati, koteroanthuamatha kukhala omasuka komanso athanzimpweya, ndikupulumutsanso mphamvu komanso kuteteza chilengedwe.

3.Polimbana ndi ntchito yanyengo, fyuluta ya HEPA imatha kusefa fumbi, mwaye ndi PM2.5 etc.

4.Chepetsani ntchito yowononga phokoso, anthu samapirira kusokonezeka komwe kumachitika chifukwa chotsegula mazenera, kupangitsa chipindacho kukhala chodekha komanso chomasuka.

5.Zotetezeka komanso zosavuta, ngakhale kulibe munthu kunyumba, zimatha kupereka mpweya wabwino kuti zipewe kuwonongeka kwa katundu ndi chitetezo chamunthu chifukwa chotsegula mazenera.
