I-Air Quality Index (AQI) imele amanqanaba oxinzelelo longcoliseko lomoya. Ibeka amanani kwisikali esiphakathi kwe-0 kunye ne-500 kwaye isetyenziselwa ukunceda ekumiseleni xa kulindeleke ukuba umgangatho womoya ungabi sempilweni.
Ngokusekelwe kwimigangatho yomgangatho womoya karhulumente, i-AQI ibandakanya amanyathelo okulinganisa izinto ezintandathu eziphambili zongcoliseko lomoya: i-ozone, i-carbon monoxide, i-nitrogen dioxide, i-sulfur dioxide, kunye nobukhulu obubini bezinto ezincinci. Kwi-Bay Area, izinto ezingcoliseko ezinokubangela i-Spare the Air Alert yi-ozone, phakathi kuka-Epreli no-Okthobha, kunye nezinto ezincinci, phakathi kukaNovemba noFebruwari.
Inombolo nganye ye-AQI ibhekisa kubungakanani obuthile bongcoliseko emoyeni. Kwinkoliso yezingcolisi ezintandathu ezimelwe yitshati ye-AQI, umgangatho welizwe uhambelana nenani le-100. Ukuba uxinano longcoliseko lunyuka ngaphezu kwe-100, umgangatho womoya unokuba yingozi kuluntu.

Ukufundwa okungaphantsi kwe-100 kwi-AQI akufanele kuchaphazele impilo yoluntu ngokubanzi, nangona ukufundwa okuphakathi kwe-50 ukuya kwi-100 kunokuchaphazela abantu abanovakalelo olungaqhelekanga. Amanqanaba angaphezu kwe-300 awafane afumaneke eMelika.
Xa i-Air District ilungiselela uqikelelo lwemihla ngemihla lwe-AQI, ilinganisa uxinaniso olulindelekileyo kwingcoliseko nganye kwezintandathu ziphambili ezibandakanyiweyo kwisalathiso, iguqula ukufundwa kube ngamanani e-AQI, kwaye ixele inani eliphezulu le-AQI kwindawo nganye yengxelo. Isilumkiso se-Spare the Air sibizwa kwi-Bay Area xa umgangatho womoya kulindeleke ukuba ungabi sempilweni kuyo nayiphi na indawo ezintlanu zengxelo zommandla.
