Window Air: Open or Vent Now
Air Quality Alert for Pollen
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Pollen or wildfire smoke outside? Window Air checks live air quality and tells you whether to open your windows, vent briefly, or keep them closed today.
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.
