OpenWindow
Know when to open your window or keep shut
If we've been a breath of fresh air for you, help us keep the mission alive.
How it works
Why your window matters
Indoor air can be 5x more polluted than outdoor air. However, opening windows during high-pollution peaks invites PM2.5 particulates into your lungs. Timing is everything.
The Intelligence Engine
Our algorithm cross-references hyper-local AQI, thermal comfort indices, and humidity. We only trigger "YES" when outdoor air quality outperforms indoor averages.
Global Health Standards
We align with WHO and EPA guidelines. A "NO" verdict is strictly enforced if AQI exceeds 100 or if active precipitation is detected.
