Indoor Air Quality (IAQ) Systems
Indoor Air Quality (IAQ) Systems are integrated smart monitors that measure several air pollutants together in one connected unit: CO2, VOCs, PM2.5/PM10, humidity, temperature, and sometimes formaldehyde and radon. Particularly useful in modern tightly sealed buildings where pollutants can accumulate indoors when ventilation is insufficient.

About this category
IAQ systems solve a multi-dimensional problem: indoor air can hold several pollutants affecting health, comfort, and productivity simultaneously. The design: a desktop-sized integrated unit holding a CO2 sensor (NDIR), a VOC sensor (PID or MOS), a PM2.5/PM10 sensor (laser), a temperature and humidity sensor, sometimes a formaldehyde sensor (an important building-material pollutant), a color display, a Wi-Fi port for data, a smartphone app, and integration with the building BMS. Measured indicators and meanings: CO2 (ventilation level), VOC (chemical pollutants), PM2.5 (lung-penetrating particles), humidity (linked to mold risk if elevated or mucous-membrane dryness if low), temperature (thermal comfort), and formaldehyde (building materials). System integration: smart buildings (automatic increase of ventilation on rising CO2), HVAC (switching extra filters on rising PM2.5), and smart alerts (sending notifications on threshold crossing). Applications: smart commercial buildings, schools (improving the learning environment), hospitals (supporting air-quality monitoring), modern offices (productivity gains), homes of allergy and asthma sufferers, nurseries and intensive-care units, printing and laboratory facilities, and research labs. A substantive difference from individual monitors: IAQ is integrated — it fuses measurements, delivers a complete picture, and connects to building systems; individual monitors are cheaper but need multiple units. Measurement ranges, accuracy, and thresholds vary between models — review the product documentation and application requirements before installation.
