Does an air quality monitor replace a CO alarm or smoke detector?
Reviewer consensus
No. Most smart AQ monitors are not UL-listed life-safety devices and will not wake you up at code-required thresholds. Keep a dedicated CO alarm and smoke detector — units like the Kidde combination plug-in exist specifically because building codes require certified life-safety hardware that an Airthings or Govee monitor doesn't replace.
