Why Indoor Air Quality Matters

According to the U.S. Environmental Protection Agency (EPA), indoor air can be 2–5 times more polluted than outdoor air, and Americans spend approximately 90% of their time indoors. Monitoring CO2 levels, VOCs, and formaldehyde helps you take proactive steps to maintain a healthier living and working environment through better ventilation and air management.
