VOC regulation in Swegon’s WISE-system

A typical VOC sensor in a ventilation system detects substances naturally emitted by humans such as acetone in our breath, and methane from digestive processes. This means that the VOC levels fluctuate in step with the CO 2 levels, and means that both metrics can be used in matching a ventilation system’s air replacement rate
