Our Pick

Reduce Indoor Ozone in Bakersfield

Today's main pollutant in Bakersfield is ground-level ozone (AQI 129). 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.
