ozoni (o3) ndi mpweya wosakhazikika wokhala ndi maatomu atatu a oxygen.

 
kwenikweni ozoni ndi oxidizer wamphamvu kwambiri kuposa mankhwala ena wamba monga chlorine ndi hypochlorite.

ozoni yoyeretsa mpweya imapangitsanso kununkhira komanso kutseketsa mabakiteriya.
potero mpweya umakhala wabwino mwachibadwa chifukwa gwero la fungolo lawonongeka.

ozoni amachita mwachindunji pa makoma ma cell a tizilombo.

Mosiyana ndi ma biocides ena oxidizing ndi osatulutsa okosijeni ayenera kunyamulidwa kudutsa nembanemba yam'manja momwe amagwirira ntchito panjira yoberekera ya nyukiliya kapena ma enzymes ofunikira kuti kagayidwe kake ka maselo.

pa ntchito zamalonda komabe njira yophera tizilombo toyambitsa matenda iyeneranso kuwonedwa pokhudzana ndi zinthu zomwe zingagwirizane ndi ozoni.

Zina mwazomwe zimagwiritsidwa ntchito ndi ozoni pothandizira mpweya ndi izi:
mpweya wabwino ndi makina oziziritsira mpweya wowongolera fungo la mpweya komanso kuwongolera mpweya wamkati m'malo osiyanasiyana omanga.
khitchini ndi chakudya kununkhiza ?
kuwongolera fungo lachimbudzi m'malo opopera.
zinyalala bin pakati fungo (volatile organic mankhwala) kulamulira.
kuwongolera kununkhira kwachimbudzi.
Chithandizo cha mpweya m'chipinda chozizira chowongolera fungo la tizilombo tating'onoting'ono ndikuwonjezera moyo wa alumali wa zokolola zatsopano.

komabe kuwongolera fungo pogwiritsa ntchito ozoni nthawi zambiri kumatheka chifukwa cha makutidwe ndi okosijeni azinthu zosakhazikika za organic - vocs - kapena zinthu zopanda organic.

chifukwa cha chitetezo palibe anthu ayenera kulowa m'chipindacho mpaka mlingo wa ozoni wotsalira uli pansi pa 0.02 ppm.
