Identifying poorly ventilated areas and using CO2 monitors

CO2 monitors are not suitable for use in areas that rely on air cleaning units because these remove contaminants (such as coronavirus) from the air but do not remove CO2. In large, open spaces and spaces with higher ceilings, such as food production halls or warehouses, you can’t be sure the air is fully mixed and CO2 monitors may be less representative.
