THE SCIENCE
Air Quality Index (AQI)
We use real-time AQI data (1-5 scale). Levels 4-5 contain harmful particles (PM2.5, PM10, ozone) that affect respiratory health.
Good (1-2): Safe to open
Moderate (3): Sensitive groups caution
Poor (4-5): Keep windows closed
Humidity Control
Humidity above 70% promotes mold growth. Below 30% causes dryness. We recommend ventilation only when humidity ≤ 70%.
30-60%: Ideal indoor range
Above 70%: Avoid ventilation
Below 30%: Use humidifier
Decision Algorithm
Otherwise, keep windows closed to maintain healthy indoor air quality.
