For commercial applications, we can arrange an installation of a building automated control systems to alarm and increase ventilation rates when CO2 and VOCs concentrations reach unacceptable limits. 

Airborne Mold Testing & Moisture Detection

 Humid or damp conditions in the home, school or workplace may promote the growth of molds, as well as bacteria and dust mites. These organisms may contribute to poor indoor air quality and can cause health problems. Ottawa has experienced record rain and snowfall in recent years which has significantly contributed to number of buildings and homes affected by moisture related problems. Indoor air quality problems are generally microscopic. A visual inspection is not adequate to provide an accurate picture of the mold concentration in a room. Testing should be part of a thorough inspection or assessment.
