I have AirGradient but this product seems appealing too. It's smaller, portable, doesn't need external power supply and looks better. I also like how the UI looks, it's clearly designed by someone with a visual / artistic taste, the UX could be improved though.

The big question is accuracy, that's possibly a major advantage of AirGradient.

Thanks! AirGradient is great! They do a very good job and served as an inspiration to us!

On CO2-Sensor Accuracy: Based on AirGradients own research[1], the SCD41 (which Air Lab uses) and SenseAir S8 (which AirGradient uses), compare well indoors. In outdoor environments, the AirGradients sensor is generally better. As the Air Lab is primarily focused on indoor environments, we chose the smaller SCD41 to fit the portable design. But yes, If you're looking for an outdoor air quality monitor, AirGradient will be more accurate.

How about temperature accuracy? AirGradient did a bunch of tests and adjustments to mitigate effects of insufficient air circulation and heat from electronics.
