I was very surprised by how high my CO2 was in the house! I’m now ventilating every morning. My IQ Air GC is keeping my indoor air at zero for the 2.5 particles. .
Great device! Monitors both CO2 and air pollution levels. Only missing feature is the ability to monitor outdoor CO2 on a map like air pollution can be tracked. This would be helpful scientific data to have to help track climate change.
Nice little device. In the summer, when the doors and windows are open, it measures the particulate level. In the winter when things are shut up tighter than a drum, it will be far more helpful.
