How Irvine Air Quality Changed by Season in 2022
Spring (Mar–May): Usually Irvine's cleanest stretch, with AQI near 27. Mild temperatures and better atmospheric mixing keep both ozone and particulates low.
Summer (Jun–Aug): AQI climbs toward 69 as heat and sunlight drive ozone formation to its yearly peak. Afternoons are the worst time to be outside.
Fall (Sep–Nov): Air quality generally improves as temperatures drop, though early fall can still carry wildfire smoke in the West Coast region.
Winter (Dec–Feb): AQI near 47. Cold-air temperature inversions can trap PM2.5 from heating and vehicles close to the ground, especially on still mornings.

Reduce Indoor Ozone in Irvine
Today's main pollutant in Irvine is ground-level ozone (AQI 41). Important: standard HEPA filters do NOT remove ozone — only a purifier with a substantial activated-carbon bed adsorbs it. The biggest wins are cutting indoor sources (gas appliances, certain "ionizer" purifiers) and ventilating when outdoor ozone is low (early morning). A high-carbon unit helps with the gases and VOCs that linger indoors.
