1. Tacewar injina ko tacewar kafofin watsa labaru (Mechanical tacewa ko Porousmedia tacewa) yana da tasirin tacewa a fili akan kwayoyin halitta kuma yana da amfani ga lafiyar dan adam.
2. Shaidu sun nuna cewa saboda alaƙa da sigogin jihohi da yawa, kawar da tasirin abubuwan tacewa na lantarki akan abubuwan da ke cikin iska yana ba da babban kewayo: daga ingantacciyar tasiri zuwa tasiri sosai.Haka kuma, tasirin sa na dogon lokaci yana da alaƙa da yanayin kula da na'urar.Tun da electrofilters suna aiki akan ka'idar ionization, akwai haɗarin haɓakar ozone.
3. Sorbent yana da tasirin cirewa a fili akan gurɓataccen iskar gas.Nazarin ya nuna cewa jin warin mutane yana da ingantaccen kimantawa akan tasirin cire shi.Koyaya, har yanzu akwai ƙarancin shaidar kai tsaye ko yana da amfani ga lafiya.Duk da haka, adsorbents na jiki ba su da tasiri a kan duk abubuwan da ba su da kyau.Yana da tasiri mafi girma akan kwayoyin halitta marasa iyaka, babban wurin tafasa, da manyan gurɓataccen iskar gaseous na kwayoyin.Don ƙananan abubuwan da ke da nauyin kwayoyin da ke ƙasa da 50 da babban polarity, irin su formaldehyde, methane da ethanol, ba shi da sauƙi don ƙarawa.Idan adsorbent ya fara watsa abubuwan gurɓatawa tare da ƙananan nauyin kwayoyin halitta, polarity da ƙananan tafasa, lokacin da ya ci karo da kwayoyin halitta marasa iyaka, babban wurin tafasa, da gurɓataccen iska mai nauyin kwayoyin halitta, zai saki (desorb) wani ɓangare na gurɓataccen gurɓataccen abu a baya. , wato akwai gasar talla.Bugu da ƙari kuma, ko da yake physisorbents suna sake farfadowa, tattalin arziki ya cancanci la'akari.
4. Wasu nazarin sun nuna cewa photocatalytic oxidation yana da tasiri wajen lalata kwayoyin halitta da kwayoyin halitta, duk da haka, akwai kuma shaida cewa ba shi da wani tasiri.Photocatalyst yana amfani da haskoki na ultraviolet don haskaka saman mai kara kuzari don inganta bazuwar abubuwa masu cutarwa akansa zuwa carbon dioxide da ruwa, amma tasirinsa yana da alaƙa da lokacin hulɗa, ƙarar iska, da yanayin yanayin mai kara kuzari.Idan matakin bai cika ba, ana iya samar da wasu abubuwa masu cutarwa kamar ozone da formaldehyde.
5. Bincike ya nuna cewa hasken ultraviolet (UV-C) na iya yin tasiri wajen hana ayyukan gurɓata ruwa ko kashe su, amma a yi hattara da yuwuwar ozone.
6. Ozone (Ozone) yana da illa ga lafiyar ɗan adam.Iyakar fiddawa da aka yarda da Kwamitin Lafiyar Muhalli na ASHRAE a cikin 2011 shine 10ppb (bangare ɗaya cikin 100,000,000).Koyaya, a halin yanzu babu yarjejeniya kan ƙimar iyaka, don haka bisa ga ka'idar taka tsantsan, ya kamata a yi amfani da fasahohin tsarkakewa waɗanda ba sa haifar da ozone gwargwadon yiwuwa.
7. Mai tsarkake iska (Makuncin tsabtace iska) samfuri ne ta amfani da fasahar tsarkake iska guda ɗaya ko da yawa.
8. Samun iska hanya ce mai tasiri don cire gurɓataccen cikin gida lokacin da ingancin iska na waje yayi kyau.Yin amfani da tacewa da sauran fasahohin tsaftace iska na iya rage buƙatar samun iska.Lokacin da iskar waje ta ƙazantu, dole ne a rufe kofofin da tagogi.

Lokacin daingancin iska na wajeyana da kyau, samun iska ba shakka shine mafi kyawun zaɓi.Koyaya, idan iskar waje ta gurɓace, buɗe tagogi don samun iska zai busa gurɓatawar waje zuwa cikin ɗakin, wanda ke ƙara tabarbarewar gurɓataccen muhalli na cikin gida.Don haka ya kamata a rufe kofofi da tagogi a wannan lokaci, sannan a kunna na'urorin tsabtace iska mai saurin zagayawa don kawar da gurbacewar iska cikin gaggawa.

Dangane da lalacewar ozone ga lafiyar ɗan adam, da fatan za a yi hattara game da samfuran da ke amfani da fasahar lantarki mai ƙarfi don tsarkake iska, koda irin waɗannan samfuran suna samar da rahoton bincike daga hukumomin bincike.Saboda samfuran da aka gwada a cikin irin wannan nau'in rahoton dubawa duk sabbin injina ne, zafin iska yayin gwajin bai canza ba.Lokacin da aka yi amfani da samfurin na ɗan lokaci, ƙura mai yawa ya taru a cikin ɓangaren ƙarfin wutar lantarki, kuma yana da sauƙi don samar da al'amuran fitarwa, musamman ma a cikin yanayi mai laushi a kudu, inda zafi na iska ya kasance sau da yawa. sama da kashi 90% ko sama da haka, kuma yanayin fitarwa mai ƙarfi yana iya faruwa.A wannan lokacin, na cikin gida Tsarin sararin samaniya yana da sauƙi don wuce ma'auni, wanda ke lalata lafiyar masu amfani kai tsaye.
