With our population now spending approximately 90%+ time indoors and 65% of that at home, indoor air quality and pollution is a growing concern. Your HVAC (Heating, Ventilation & Air Conditioning) systems have been shown to be a collection source for a variety of contaminants such as:

• Dust
• Dirt
• Pollen
• Animal dander
• Tobacco smoke

Over time these contaminants can build up and can create ideal conditions for microbiological growth (mold, bacteria), which could be circulated into your building, affecting the comfort and health
of occupants.
