  1. Check CADR, its units and the stated room-sizing assumptions.
  2. Identify the filter types and what the manufacturer says they address.
  3. Compare noise and power at the fan setting you expect to use.
  4. Check filter availability, replacement cost and automation options.

Air Quality Monitors

Air quality monitors report the environmental measurements supported by their sensors. A particulate reading, a VOC estimate and a direct carbon dioxide measurement describe different conditions.

Temperature & Humidity Sensors

Temperature and humidity sensors report ambient conditions at the sensor location. Accuracy, placement and reporting interval determine how useful the readings are.
