Window Air: Open or Vent Now

Should you open your windows right now? Window Air turns live outdoor air quality into one clear answer - OPEN, VENT, or KEEP CLOSED - based on your local conditions and your sensitivities.

You crack a window for fresh air and let in pollen. You keep it shut on a beautiful day when the air outside was actually clean. The data exists - AQI, PM2.5, pollen, wildfire smoke, humidity - but reading five dashboards every morning is nobody's routine.

HOW IT WORKS
1. Set your sensitivities: pollen, smoke, dust, or general air quality.
2. Window Air pulls live outdoor air data for your location.
3. You get a single verdict - OPEN, VENT, or KEEP CLOSED - with the reason and the best time window today.
It takes 20 seconds to set up. No account required.
