Is it safe to go outside in Pittsburgh today?
Pittsburgh, PA’s air changes day to day. BreathCount checks the current air quality (AQI), pollen, and heat and turns it into one plain-language decision — instead of leaving you to interpret a raw number. Free, no account, no install.
What affects Pittsburgh’s air
Pittsburgh sits in river valleys that can trap fine particles, and it consistently ranks among the worse U.S. metros for year-round particle pollution (PM2.5).
- Fine particle pollution (PM2.5) from industry and traffic
- Summer ozone on hot, sunny afternoons
- Winter temperature inversions that trap smoke in the valleys
Particle pollution can climb during winter inversions and on still summer days; ozone runs highest on hot afternoons.
From a number to a decision
Official sources give Pittsburghan accurate AQI number. They don’t tell you whether to run this morning, send the kids to recess, or move practice indoors. BreathCount reads the current AQI, pollen, and heat together and gives you a plain-language answer for your situation — general, exercise, kids, or sensitive groups — plus a short note you can share.

What AQI is okay for outdoor exercise in Pittsburgh?
There's no single cutoff. As AQI rises, sensitive groups — kids, older adults, and people with asthma or heart conditions — may want to ease up first, and everyone may want to cut back on long, intense efforts on higher days. BreathCount turns the current number into activity-specific guidance. This isn't medical advice; always follow official alerts.
