Ukuhlanzwa kwegesi engcolile yezimboni kubhekisela kakhulu ekwelapheni igesi engcolile yezimboni njengezinhlayiya zothuli, intuthu, igesi enukayo, amagesi anobuthi nayingozi akhiqizwa ezindaweni zezimboni.
Igesi elahliwe ekhishwa yimikhiqizo yezimboni ivame ukuba nemiphumela eyingozi emvelweni nasempilweni yabantu. Kufanele kuthathwe izinyathelo zokuhlanza ngaphambi kokuba umoya okhishwayo uhlangabezane nezidingo zezindinganiso zokukhishwa kwegesi ephumayo. Le nqubo yaziwa ngokuthi ukuhlanzwa kwegesi elahliwe.
Indlela yokungenisa esetshenziswayo i-adsorbent (i-activated carbon, i-molecular sieve, i-purification desiccant) ukuze imunce ukungcola kugesi yokukhipha umoya yezimboni, futhi i-adsorbent efanele ikhethwa izingxenye ezahlukene zegesi yokukhipha umoya. Lapho i-adsorbent ifinyelela ekugcwaleni, ukungcola kuyasuswa, bese kusetshenziswa ubuchwepheshe bokushisa obusebenzisa i-catalytic ukuze kufakwe izinto eziphilayo zibe yi-carbon dioxide namanzi kugesi engcolile yezimboni, ngaleyo ndlela kufezwe umshini kanye nemishini yokusiza ngezinjongo zokuhlanza.
