AirGradient ONE vs Awair Element: Which Should You Buy?
A spec-by-spec comparison of the AirGradient ONE ($150) and the Awair Element ($200) — accuracy, sensors, connectivity, and which one fits your situation.
Quick Verdict
The AirGradient ONE is $50 cheaper; the AirGradient ONE has the tighter stated CO2 accuracy (±50 ppm); the AirGradient ONE tracks more parameters (6 vs 5).
Choose the AirGradient ONE if you want to spend less, or measurement accuracy is your priority, or you want the fuller picture (CO2, PM2.5, Temperature, Humidity, VOC, NOx).
Choose the Awair Element if its NDIR sensor and feature set fit your use case better.

Frequently Asked Questions
Which is better, the AirGradient ONE or the Awair Element?+
The AirGradient ONE is $50 cheaper; the AirGradient ONE has the tighter stated CO2 accuracy (±50 ppm); the AirGradient ONE tracks more parameters (6 vs 5). Choose the AirGradient ONE if you want to spend less, or measurement accuracy is your priority, or you want the fuller picture (CO2, PM2.5, Temperature, Humidity, VOC, NOx). Choose the Awair Element if its NDIR sensor and feature set fit your use case better.
Is the AirGradient ONE or Awair Element cheaper?+
The AirGradient ONE is the more affordable option at $150, versus $200 for the Awair Element.
Do both use real CO2 sensors?+
The AirGradient ONE uses a NDIR sensor; the Awair Element uses a NDIR sensor. NDIR and photoacoustic sensors measure CO2 directly, unlike eCO2 estimators.
Which measures more air quality parameters?+
The AirGradient ONE tracks more, with 6 parameters (CO2, PM2.5, Temperature, Humidity, VOC, NOx), compared with 5 for the Awair Element.
