SmartAirLA empowers communities to protect their health from pollution with data-driven tools.
Our efforts:
  • Reduce asthma-related hospitalizations.
  • Decrease asthma-related student absenteeism, with fewer parents missing workdays to care for their afflicted children.
  • Lessen exposure to pollution that can lead to asthma.
Together with our partners, we launched the FightAsthma Tracker.   The Tracker equips asthma patients to prevent asthma attacks by receiving alerts when asthma danger is high and checking their symptoms and home for asthma triggers.
