IQAir AirVisual Pro Overview
The IQAir AirVisual Pro is a professional-grade CO2 monitor that tracks CO2, PM2.5, Temperature, Humidity and AQI. It uses a NDIR sensor — the technology we recommend for reliable CO2 readings — with a stated accuracy of ±50 ppm across a 400-10000 ppm measurement range. At $500, it is aimed at professional applications, home use, offices and smart home setups.
In day-to-day use, the AirVisual Pro offers an onboard display, so you can read levels at a glance without opening an app, plus WiFi connectivity for logging trends and setting alerts, plus a stationary design (USB powered + 4-hour battery) best suited to continuous monitoring in a fixed location.
