Smart Air Quality Monitors (AQI Testers) for Accurate Environmental Control
Monitor PM levels, gases, and ambient conditions in real time with Enviro Testers’s scalable, cloud-connected AQI testing solutions.

Smart Air Quality Monitoring for Safer, Healthier Environments
“Air quality monitoring is an essential component of environmental management and regulatory compliance in today’s workplaces, educational institutions, healthcare facilities, and public spaces. Air Quality Monitors (AQI Testers) are intelligent systems designed to detect airborne pollutants and climate parameters that directly affect health, comfort, and equipment performance. These devices measure key indicators such as particulate matter (PM2.5 and PM10), carbon dioxide (CO₂), carbon monoxide (CO), volatile organic compounds (VOCs), temperature, and humidity.”
“By transforming raw sensor data into actionable Air Quality Index (AQI) ratings, these testers help organizations take preventive measures, optimize HVAC systems, and safeguard staff and occupant wellbeing.Enviro Testers supports a wide range of B2B clients across North America with smart, reliable, and scalable AQI testing solutions. We provide tailored technologies designed to meet real-world industry challenges. Our expertise in delivering integrated environmental systems ensures that our clients benefit from high-performance tools backed by expert guidance and dependable support. ”

Case Studies
United States: Distribution Center, Chicago, IL
A 250,000 sq. ft. logistics facility in Illinois integrated Enviro Testers’s AQI testers to monitor airborne dust and CO₂ levels in real time. Integration with the HVAC system allowed automatic adjustment of ventilation rates. The result: a 30% increase in indoor air quality scores and a noticeable drop in employee health complaints.
United States: Smart Office Campus, Seattle, WA
A technology firm in Washington deployed Enviro Testers’s cloud-based air monitors across three office towers. Employees accessed real-time AQI data through mobile apps, improving awareness and productivity. The facility met WELL Building Standard™ benchmarks within six months of implementation.
Canada: Research Hospital, Toronto, ON
A biomedical research facility installed Enviro Testers AQI testers in their laboratories and clean rooms. Integrated with their environmental control systems, the solution ensured that CO₂ and VOC levels remained within safe thresholds, protecting both researchers and sensitive experiments.
