Indoor Air Quality

Scientific studies have shown that the quality of air indoors, where we typically spend 90% of our time, is commonly worse than outdoor air. Although biological pollutants, like mold, seem to dominate Indoor Air Quality (IAQ) problems, carbon monoxide,

chemicals off-gassing from building products, and inadequate fresh outdoor air ventilation are also sources of problems. 

Our agency has a nationally recognized Indoor Air Quality Program that helps citizens, schools and agencies through the process of finding solutions to indoor air problems. 


We provide free presentations on a variety of topics related to Indoor Air Quality. From 20 minutes to full day workshops, our Indoor Air Specialist will entertain your group with customized multi-media presentations loaded with useful information.
