DATA-DRIVEN AIR ACTION
Indoor Air Quality Monitors
You cannot fix what you do not measure. Modern IAQ monitors measure real-time PM2.5, CO2, TVOCs, and radon, giving you objective evidence when your ventilation or filtration needs attention.
Typical Lifespan: Non-consumable (sensors rated 5-10 years)
Price Range: $100 – $299
Evaluation Standard: ASHRAE 52.2 & AHAM CADR
Essential Buyer Selection Criteria for Air Monitors
- NDIR CO2 Sensor Quality: Look for genuine Non-Dispersive Infrared (NDIR) optical sensors rather than estimated eCO2 derived from VOC measurements.
- Laser Particle Counters: PM2.5 sensors must use reliable laser scattering to detect respirable fine particles and wildfire smoke.
- Connectivity & Data Logging: Local e-ink displays provide instant glances, while Bluetooth/Wi-Fi logging reveals overnight CO2 buildup in closed bedrooms.
