What Should You Check Before Buying?

Use these air quality monitors requirements to narrow your shortlist, then verify each requirement for the exact model.

  1. List the actual sensors and distinguish measured values from estimates.
  2. Check measurement units, calibration and stated accuracy.
  3. Verify data history, export and alert options.
  4. Confirm which readings your automation platform can access.

Air Purifiers

Air purifiers move air through a treatment system. Compare the specified clean-air delivery, room-sizing assumptions and replacement filters for the intended room.

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.
