Many people underestimate how quickly CO₂ levels can rise in a room full of people. When the concentration exceeds 1,000 ppm , concentration, well-being and learning ability drop significantly. Use our calculator to see how often you should air out your room.
Calculate how often you should air out your room by entering information about the room you are in and the number of adults/children in the room.
Note: An average adult exhales approximately 0.004–0.005 m³ CO2 per hour at rest. A child typically produces 60–75% of the CO2 an adult exhales per day. If the calculated steady-state during ventilation is below 1,000 ppm, the room will not reach the limit – and additional ventilation is not necessary under the entered assumptions.

The question is: Do you remember that?
Even when you know how often you should air out, it's easy to forget in a busy everyday life. We've all experienced sitting in a stuffy classroom or meeting room where the air gets bad without anyone reacting. The consequence is:
Lost concentration
Higher sick leave
More frequent headaches
Worse well-being
SKYEN reminds you to air out when the indoor climate is poor.
SKYEN is a simple sensor that measures the indoor climate and lights up red when it's time to air out. When the air is fresh again, it changes back to blue. This makes it easy for both children and adults to remember the important airing out.
