Indoor Air Quality Sensor
RESET-certified air-quality sensor installed in the main living area or ducts. (At Platinum, sensor measures CO₂, TVOC, humidity, temp, and PM2.5.)
Spec
Applies uniformly from Gold upward.
Scope
Continuous indoor air-quality monitoring in the dwelling.
Requirements
- 01.
Install a RESET-certified or ENERGY STAR-recognized air-quality sensor in the main living area, or in the return-air duct.
- 02.
Sensor must measure PM2.5 at minimum. Additional sensors for CO2, TVOC, humidity, and temperature are encouraged.
- 03.
At Platinum: sensor must measure CO2, TVOC, humidity, temperature, AND PM2.5 (full RESET Grade B).
- 04.
Sensor data must be accessible to the occupant via a display or mobile app.
Documentation
Evidence the inspector / Institute will need.
- 01.
Sensor spec sheet with the measured pollutants listed.
- 02.
Photo of installed sensor in the main living area.
- 03.
Screenshot of the occupant's monitoring app showing live readings.
Guidance
Why monitoring is the missing piece
A home can have a great ventilation system, low-VOC finishes, and HEPA filtration — and still have unexpected IAQ events from cooking, candles, new furniture off-gassing, or wildfire smoke. Continuous monitoring lets the occupant notice and act on these events rather than living with them.
