Volatile Organic Compounds (VOCs): These are gases from things like paint, cleaning supplies, and furniture. They can make you feel sick.
Carbon Dioxide (CO2): High CO2 levels mean your room needs more fresh air.
Temperature and Humidity: These affect how the air feels and can encourage mold growth.

Smart Stuff

App Connectivity: Most smart monitors connect to your phone. You can see readings anywhere.
Alerts: The monitor should send you messages when air quality is bad.
