knowing the Difference between Health Index and Air Quality Index

Health Index
Health Index provides a real-time indication of the potential risk for the spread of airborne infectious disease in a building.
Used to Reduce the Spread of Infection.
Short Measurement Cycles for Fast Remediation.
Number of Contaminants Sampled in HALO: 6-7.
Health Index Factors:
Carbon Dioxide (CO₂) • Particulate Matter (1 μm, 2.5 μm, 10 μm) • Humidity (RH) • Volatile Organic Compounds (VOC) • Nitrogen Dioxide (NO₂)

Air Quality Index
Air Quality Index provides a rolling average of the quality of the air you are breathing over the course of a few hours.
The standard for EPA to Measure Air Quality.
Long Measurement Cycles for General Air Quality.
Number of Contaminants Sampled in HALO: 4-5.
Air Quality Index Factors:
Particulate Matter (2.5 μm, 10 μm) • Carbon Monoxide (CO) • Nitrogen Dioxide (NO₂)
