Square Air CO2 is designed to give you both perspectives of indoor air quality. It captures how air actually behaves—detecting a broad mix of VOCs from materials, activities, and human presence—while also providing precise, reliable CO2 measurements.
Unlike simplified air quality solutions, it uses dedicated CO2 sensing technology to deliver accurate values required for standards, certifications, and ventilation control. High-quality CO2 sensors are calibrated and engineered to ensure stable, reliable readings over time—critical for building compliance and performance monitoring.
This means you don’t have to choose between “perceived air quality” and “regulatory accuracy.” You get both—enabling smarter ventilation, healthier environments, and full confidence in your data.
