Indoor Air Quality (IAQ) has a major impact on occupant health, comfort, productivity, and quality of life. Did you know that your students, faculty, and staff take about 20 breaths every minute on average and each breath contains more than just life-sustaining oxygen? Your K-12 facility occupants also inhale particles, spores, dust, viruses, bacteria, and germs that get circulated through buildings and transferred from occupant to occupant through breathing.
