Birdie® is an alternative and intuitive CO2-monitor improving your indoor climate & health.

90% of our life is spend indoors - often in poor air quality increasing the risk of asthma, headache, fatigue and sleep disorders. Indoor air quality is a huge but invisible problem, calling for a visible solution.

Just like the canary in the coal mine, Birdie® will drop dead when the air quality becomes poor, until you open your windows and bring it back to life. Simple as that.
