About BREATHSAFE
Empowering communities with NASA data to make informed decisions about air quality and health
Our Mission
BREATHSAFE was created to bridge the gap between complex NASA Earth observation data and everyday health decisions. We believe everyone deserves to understand the air they breathe and receive personalized guidance to protect their health and their loved ones.
How It Works
NASA Data Collection
We utilize NASA's Earth observation satellites and ground monitoring stations to collect real-time data on key air pollutants including PM2.5, NO₂, and O₃.
Scientific Analysis
Our algorithms process the data and calculate Air Quality Index (AQI) values, categorizing air quality from Good to Hazardous based on EPA standards.
Personalized Insights
Based on your health profile (pregnant, child, elderly, asthmatic, or general), we provide tailored recommendations to protect your specific health needs.
Actionable Alerts
Receive clear, actionable health alerts that help you make informed decisions about outdoor activities, exercise, and daily routines.
Understanding Air Pollution & Health
PM2.5 (Fine Particulate Matter)
Particles smaller than 2.5 micrometers can penetrate deep into lungs and enter the bloodstream. Long-term exposure is linked to cardiovascular disease, respiratory issues, and adverse pregnancy outcomes. Particularly dangerous for pregnant women and developing fetuses.
NO₂ (Nitrogen Dioxide)
Primarily from vehicle emissions and industrial sources, NO₂ irritates airways and can worsen asthma. Children exposed to high levels show increased respiratory infections and reduced lung function development.
O₃ (Ground-Level Ozone)
Forms when pollutants react with sunlight. Can trigger asthma attacks, reduce lung function, and cause respiratory inflammation. Elderly individuals are at higher risk for ozone-related health effects.
