Carbon Dioxide

Unusually high carbon dioxide levels may cause drowsiness and headaches and reduced productivity of occupants.

Moulds and Bacteria

The primary hazard of mould in indoor air quality is the triggering of asthmatic attacks in susceptible persons. The monitoring of humidity levels will inhibit the likelihood of mould growth.

Carbon Monoxide

One of the most toxic indoor air contaminants, common sources of carbon monoxide are tobacco smoke, space heaters using fossil fuels, defective central heating furnaces and automobile exhausts.

High levels of carbon monoxide can lead to nausea, unconsciousness and death.
