Monitors measure selected pollutants or environmental conditions, depending on their sensors. They do not provide a complete picture of every indoor contaminant.
Ask about the sensor and its placement
Confirm which measurements are supported, where the monitor should go, and how readings are reviewed. One location does not represent every room.
Look at changes over time
Compare readings with activities, weather, and inspection findings. A change is a reason to investigate, not proof of a specific source or equipment fault.
Know the boundaries
An air monitor does not diagnose illness, identify every allergen, or replace a smoke or carbon monoxide alarm. Ask Clean Air about the device, service scope, and membership terms before enrolling.
WHAT THE EVIDENCE SAYS
Research behind this question.
Some concerns need a dedicated test
U.S. homes · EPA national estimate, checked September 2026
EPA estimates that nearly one in 15 U.S. homes has an elevated radon level.
This is a national estimate, not a Jacksonville rate or a result for your home. Radon requires a radon-specific test or sensor.
