Mu bulamu obw’omulembe guno, ensonga z’omutindo gw’empewo zeeyongera okusikiriza abantu. Ebyuma ebitta obuwuka mu mpewo, ng'ebyuma ebisobola okulongoosa obulungi empewo ey'omunda n'okutta obuwuka, bigenda biyingira mpolampola enkumi n'enkumi z'amaka, ne bifuuka "abakuumi abatalabika" ab'obulamu bw'okussa.

Ebyuma ebitta obuwuka mu mpewo bitera okukozesa tekinologiya ow’enjawulo omugatte, gamba nga HEPA filters, ekitangaala kya ultraviolet (UVC), negative ions, ne plasma. Ebisengejja bya HEPA bisobola bulungi okukwata obutundutundu obutonotono mu mpewo, gamba ng’enfuufu, bakitiriya, n’obuwuka obusukka mu 0.3 microns; ekitangaala kya ultraviolet (UVC) kisaanyaawo ensengekera ya DNA ya bakitiriya, akawuka, n’obuwuka obulala obutonotono, ne kizifuula obutakola; tekinologiya wa negativu ion afulumya ion negativu ezigatta enfuufu, bakitiriya n’obutundutundu obulala mu mpewo, ne zizireetera okusenga n’okulongoosa empewo. Enkola ya tekinologiya ono ey’okukwatagana esobozesa ebyuma ebitta obuwuka mu mpewo okutta obulungi obuwuka, akawuka, ebikuta, obuwuka obuyitibwa spores, n’obuwuka obulala obuleeta endwadde mu mpewo.

Bw’ogeraageranya n’enkola ez’ekinnansi ez’okutta obuwuka, ekirungi ekikulu ekiri mu byuma ebitta obuwuka mu mpewo kwe kusobola okukola nga abantu baliwo. Zisobola okukola obutasalako n’okutta obuwuka mu mpewo nga tezikosa bulamu bwa bantu. Kino kifuula ebyuma ebitta obuwuka mu mpewo naddala okukozesebwa mu maka, ofiisi, amasomero, n’ebifo ebirala, ne biwa obukuumi olunaku lwonna eri obulamu bw’abantu mu kussa.

Ng’oggyeeko okutta obuwuka, ebyuma ebitta obuwuka mu mpewo bisobola bulungi okuggya omukka ogw’obulabe mu mpewo ey’omunda. Ebika ebimu bibaamu ebisengejja kaboni (activated carbon filters) ebisobola okunyiga ggaasi ezicaafuwaza ebiramu nga formaldehyde ne phenol mu mpewo. Ate era, ebyuma ebitta obuwuka mu mpewo bisobola okumalawo omukka n’obuwoowo obuva mu kunywa sigala, okuwunya okutasanyusa okuva mu binaabiro, n’okuwunya mu mubiri, ne kifuula empewo ey’omunda okubeera ennungi.

Ebyuma ebitta obuwuka mu mpewo bikola kinene mu kukendeeza ku bulabe bw’okusiiga endwadde. Mu bitongole by’ebyobujjanjabi ng’amalwaliro, ebyuma ebitta obuwuka mu mpewo bisobola bulungi okufuga obucaafu obw’okubiri obuva ku ntambula y’empewo wakati w’ebitongole eby’enjawulo ne waadi, ne kikendeeza ku bulabe bw’okukwatibwa obulwadde obw’okubiri wakati w’abalwadde n’abakozi abawerekera, awamu ne wakati w’abalwadde n’abakozi b’ebyobujjanjabi, nga kiyamba abalwadde bawona mangu. Mu maka, ebyuma ebitta obuwuka mu mpewo bisobola okuziyiza empewo embi ey’omunda okwongera ku buzito ku baserikale b’omubiri gw’omuntu, okukendeeza ku bulabe bw’endwadde z’abaserikale b’omubiri ezireetebwa obucaafu bw’empewo n’okutumbula obulamu bw’omubiri n’obwongo bw’abantu b’omu maka.

Ensimbi ezisaasaanyizibwa mu kukola ebyuma ebitta obuwuka mu mpewo ntono nnyo. Okugeza, ebyuma ebitta obuwuka mu mpewo ya plasma birina amaanyi agakozesa 1/3 gokka ag’ebyuma ebitta obuwuka mu mpewo ya ultraviolet, ekintu ekikekkereza amaanyi mangi. Ku kisenge kya 150m, amaanyi g’ekyuma kya plasma gali 150W, ate ag’ekyuma kya UV kyetaaga amaanyi agasukka mu 450W, ekikekkereza Yuan ezisoba mu 1000 mu ssente z’amasannyalaze buli mwaka. Okugatta ku ekyo, obulamu bw’ebyuma ebitta obuwuka mu plasma buba bwa myaka 15, ate obw’ebyuma ebitta obuwuka obuyitibwa ultraviolet buba bwa myaka 5 gyokka, era ebyuma ebitta obuwuka mu plasma byetaaga okukyusa ekibinja ky’ettaala buli luvannyuma lwa myaka 2, nga bigula kumpi Yuan 1000, ate eby’okutta obuwuka mu plasma ebyuma tebyetaaga bintu ebikozesebwa obulamu bwonna. Mu bbanga eggwanvu, ebyuma ebitta obuwuka mu mpewo birina omugerageranyo gw’omuwendo omunene ennyo n’okukola obulungi.

Mu bufunze, olw’ebirungi byazo ebingi eby’okutta obuwuka obulungi, okubeera awamu abantu n’ebyuma, okuggyawo ggaasi ez’obulabe, okukendeeza ku bulabe bw’okusaasaanya endwadde, n’okuba tebikekkereza ssente n’okukekkereza amaanyi, ebyuma ebitta obuwuka mu mpewo bifuuse abakuumi b’ebyobulamu abateetaagisa mu bulamu obw’omulembe guno. Ka kibeere mu maka, amalwaliro, oba mu bifo eby’olukale, ebyuma ebitta obuwuka mu mpewo bisobola okuwa abantu embeera ey’obukuumi era ennungi ey’okussa, era kisaana okuba nakyo.
