Instant feedback empowers you to identify pollution sources—such as cooking fumes, pet dander, or outdoor smog—and take timely action.

Here are a few practical use cases:

Custom alerts for high pollen days, so allergy sufferers can preemptively manage symptoms
Automated ventilation boosts post-workout to flush out CO₂ and humidity spikes
Syncing purifier schedules with smart thermostats and humidifiers for unified climate control
Real-time sharing of air quality metrics with family members or roommates

By staying ahead of pollutants, you maintain a consistently healthy environment without manual checks or guesswork.
