For more than a century, the use of canary oil as a warning in coal mines has been suggested by two Danish businessmen. Canairi is an air quality monitor that analyzes CO2 (carbon dioxide) levels in a home or building and warns people when they need room ventilation.

As its name suggests, it is Device Uses the Canary to “Dies when carbon dioxide levels exceed 1000 ppm (Parts per million).

According to its creators, Canairi uses a sophisticated but effective way Warn people when air quality is harmful to the home.

When a bird falls, the user must open a window or door to ventilate the room. Once the CO2 level falls, the yellow bird returns to its normal state.

The device was created Andreas Kofoed ი Hans Hoyt, Was inspired by the use of canary in coal mines in the late 19th century. At that time miners used these birds as an indicator. Measure the presence of firearms and avoid explosions.

Canaries die when the refractory concentration exceeds a certain range; Which warns workers about leaving the mine.

The device “dies” when the amount of CO2 exceeds the limit

While this plastic canary does not block explosions or “die”, its function is very useful. According to the Danish Health Service, “We spend 90% of our lives indoors.” Unpleasant air increases the risk of asthma, headaches, fatigue and sleep disturbances, so regular ventilation of enclosed areas is essential.

It can be placed at home, in the office or at school, thanks to the minimalist and efficient design. The canary is made of recycled plastic and It has a built-in CO2 sensor, a rechargeable battery and a wall mount.

The The estimated life of the battery is three months And can be charged via USB cable. Unlike other aerial monitors, This one has no display or press messages on the device either Smartphone.

Ventilation of the house does not have the same effect if you live in a city with a high level of pollution. Denmark is not a country that publishes headlines when smog levels are alarmingly high, as in some cities Chinese, Indian, Peru Or Mexico.

When there is a risk of environmental pollution, opening doors or windows can reduce air quality. Humans are exposed to ultra-fine particles that glide through them. In this case, it is better to control the quality of the outside air to ventilate your home in a timely manner.

Tests conducted and availability

Its creators have already tested it in homes, offices and schools. Anyone who has tried it says that it helps to remind them of the ventilation of the room and does not contradict the decoration of the room.

Ventilation of rooms 3 times a day is recommended. A custom that was very important in that period Pandemic.

There are not many units available for this internal canal. On the platform kickstarter You can get the first few units at a discount in exchange for project support. The lowest price is around US $ 113.58 for Canairi and its charging cable.

The packaging is also made of recycled paper and orders will start shipping in October this year.
