Mubuzima bwa none, ibibazo byubuziranenge bwikirere bigenda byiyongera kubantu. Imashini zanduza ikirere, nk'ibikoresho bishobora kweza neza umwuka wo mu ngo no kwica mikorobe, bigenda byinjira mu ngo ibihumbi, bihinduka "abarinzi batagaragara" b'ubuzima bw'ubuhumekero.

Imashini zangiza ikirere zikoresha ikoreshwa rya tekinoroji zitandukanye, nka filteri ya HEPA, ultraviolet (UVC) urumuri, ion mbi, na plasma. Akayunguruzo ka HEPA karashobora gufata neza uduce duto two mu kirere, nk'umukungugu, bagiteri, na virusi zirenze microni 0.3; urumuri ultraviolet (UVC) rwangiza imiterere ya ADN ya bagiteri, virusi, nizindi mikorobe, bigatuma idakora; tekinoroji ya ion irekura ion mbi ihuza umukungugu, bagiteri, nibindi bice byo mu kirere, bigatuma bituza kandi bigasukura umwuka. Ingaruka zogukoresha zikoranabuhanga zituma imashini zanduza ikirere zica neza bagiteri, virusi, ibumba, spore, nizindi ndwara ziterwa na virusi.

Ugereranije nuburyo gakondo bwo kwanduza, inyungu nyamukuru yimashini zanduza ikirere nubushobozi bwabo bwo gukora imbere yabantu. Barashobora gukomeza gukora no kwanduza ikirere bitagize ingaruka ku buzima bwabantu. Ibi bituma imashini zanduza ikirere zibereye cyane gukoreshwa mumazu, mubiro, mumashuri, nahandi, bikarinda umunsi wose ubuzima bwubuhumekero bwabantu.

Usibye kwica mikorobe, imashini zanduza ikirere zishobora no gukuraho neza imyuka yangiza mu kirere. Moderi zimwe zifite ibikoresho bya karubone ikora ishobora gukwirakwiza imyuka ihumanya ikirere nka formaldehyde na fenol mu kirere. Byongeye kandi, imashini zanduza ikirere zirashobora gukuraho umwotsi numunuko unywa itabi, impumuro mbi ituruka mu bwiherero, numunuko wumubiri, bigatuma umwuka wimbere uba mwiza.

Imashini zanduza ikirere zigira uruhare runini mu kugabanya ibyago byo kwandura indwara. Mu bigo by’ubuvuzi nkibitaro, imashini zanduza ikirere zirashobora kugenzura neza umwanda wa kabiri uterwa n’ingendo z’ikirere hagati y’amashami atandukanye n’ubuvuzi, bikagabanya ibyago byo kwandura kabiri hagati y’abarwayi n’abakozi baherekeza, ndetse n’abarwayi n’abakozi b’ubuvuzi, bifasha abarwayi bakira vuba. Mu ngo, imashini zanduza ikirere zirashobora gukumira umwuka mubi wo mu ngo kutongera umutwaro ku mikorere y’umubiri w’umuntu, bikagabanya ibyago by’indwara z’umubiri ziterwa n’umwanda w’ikirere no guteza imbere ubuzima bw’umubiri n’ubwenge bw’abagize umuryango.

Igiciro cyo gukora cyimashini zanduza ikirere ni gito. Kurugero, imashini yo kwanduza plasma yo mu kirere ifite ingufu zingana na 1/3 gusa cy’imashini zanduza ultraviolet, zikoresha ingufu nyinshi. Kucyumba cya 150㎡, ingufu za mashini ya plasma ni 150W, mugihe iy'imashini ya UV isaba hejuru ya 450W, ikiza amafaranga arenga 1000 mu fagitire y'amashanyarazi ku mwaka. Byongeye kandi, ubuzima bwa serivisi zimashini zanduza plasma zigera ku myaka 15, mugihe iy'imashini zanduza ultraviolet ari imyaka 5 gusa, kandi imashini zanduza ultraviolet zigomba gusimbuza itara buri myaka 2, igatwara amafaranga agera ku 1000, mugihe plasma yanduye imashini ntisaba ibikoreshwa mubuzima. Mugihe kirekire, imashini zanduza ikirere zifite igiciro kinini-cyimikorere.

Muri make, hamwe nibyiza byabo byinshi byo kwica mikorobe neza, kubana n’imashini zabantu, kuvanaho imyuka yangiza, kugabanya ingaruka zanduza indwara, no kuba ubukungu n’ingufu zikoresha ingufu, imashini zanduza ikirere zahindutse abashinzwe ubuzima mu buzima bwa none. Haba mu ngo, mu bitaro, cyangwa ahantu hahurira abantu benshi, imashini zanduza ikirere zirashobora gutanga abantu bahumeka neza kandi bafite ubuzima bwiza, kandi birakwiye gutunga.
