Poor indoor air quality significantly reduces cognitive function, concentration, and decision-making abilities, directly impacting workplace productivity and performance. Studies show that employees in buildings with better air quality demonstrate improved cognitive scores and faster response times. Contaminated air increases sick days, reduces employee satisfaction, and can trigger workers’ compensation claims for respiratory problems. For employers, the cost of productivity losses and health claims far exceeds the investment in professional air quality testing. Many jurisdictions require workplace air quality documentation for occupational health compliance. Professional testing helps employers demonstrate due diligence, reduce liability, and create healthier work environments that improve both employee wellbeing and business performance.
