Why is the carbon monoxide (CO) level so high?

The most likely cause of a high reading is the presence of carbon monoxide (CO) in the air. Carbon monoxide is extremely toxic, and to be on the safe side, you should immediately ventilate the room vigorously.

The carbon monoxide (CO) sensor in the air-Q measures according to an electrochemical measuring principle. It can come here by various effects e.g. climatic shocks to a shift of the zero line. This can be remedied by a calibration.

See here: How do I perform a manual calibration?

Another cause for selectively very high or deviating measured values can also be the cross-sensitivities, which the carbon monoxide sensor has. For example, it reacts slightly positive to Hydrogen (H₂).

Therefore, all general conditions must be checked and the measured values must also be brought into connection with the measured value of the VOC-Sensor in the air-Q in order to exclude possible cross-sensitivities as a cause.
