Why Indoor Air Quality Matters
According to the U.S. EPA, indoor air can be 2–5 times more polluted than outdoor air—sometimes even 100 times.
And with over 90% of our time spent indoors, that’s a serious concern.
The WHO also links poor indoor air quality to millions of premature deaths every year.
Monitoring your air isn't optional—it’s essential for long-term health and wellbeing.
PuffiAir Connects with Your Mobile App
PuffiAir seamlessly connects with your mobile app, allowing you to monitor real-time air quality data such as CO₂, temperature, humidity, and PM levels.
