Canairi is an intuitive CO2 meter. If the air quality is poor, Canairi will drop dead until you open the window and breathe in fresh air. In concrete terms, this means that if the CO2 content is above 1,000 ppm for more than 10 minutes, Canairi will sink. If the CO2 level drops below 800 ppm again, Canairi automatically returns to a standing position. Canairi is a patented and award-winning Danish design based on high-quality CO2 sensor technology from Switzerland. Canairi is made from recycled plastic and discontinued according to WHO recommendations. The name Canairi is inspired by the canary used by miners to be reminded of toxic gases: when the bird fainted, it was time to get out of the mine. The bird is easy to mount on a wall. It comes with a wall bracket as well as 1 screw and 1 raw plus. The battery life is about 8 months with regular use. Canairi can be charged using a USB-C cable that is included.
