Guide to Indoor Air Quality Monitoring Devices for the Healthy Home

Indoor air quality is poised to become one of the important drivers for whole house oriented businesses delivering healthy, efficient, comfortable buildings. One of catalysts for this opportunity is the explosion of sensors and devices for measuring and testing the air quality in buildings, including particulates, volatile organic compounds (VOC’s), temperature, humidity, CO2 and others. A key part of the smart home/connected home trend, these devices are increasingly available and affordable, and are coming to market at a torrid pace. Sensors and measurement devices that were once expensive and only for professional use are now available to any homeowner, can be installed for 24/7/365 monitoring, and are selling for prices under $200.

The team at Energy Circle, along with clients and industry partners, is committed to tracking these devices. We plan to add to this Guide to Indoor Air Quality Monitoring document over time. We welcome your input on our evaluation, on new products we might not be aware of, and any other comments. Please chime in and help us build out this resource.

Air Advice

Air Advice

air advice monitor

The M5200 AirAdvice Monitor is an American-made, professional grade indoor air quality monitor that measures six IAQ parameters. It is intended for temporary placement in homes by contractors and other professionals. The M5200 model has a feature not in prior models that collects IAQ data for 30 minutes and then uploads the report via 4G service. This enables the contractor/diagnostitian to deliver initial findings immediately after installation. The M5200 also generates a traditional, multi-day SmartIAQ report. Both reports compare detected levels to standards set by health authorities like the World Health Organization, US EPA, ASHRAE and OSHA.  

Pricing
  • $2,490, with annual subscription fees of $995.00 (Some discounts are available to qualified contractors). Pricing also includes annual sensor re-calibration as well as more frequent re-calibration if built-in diagnostics indicate need.
  • Status: Available For Contractors in the U.S., Canada, China & Japan.
Features
  • Complete with 6 sensors that can detect the following:
  • Particulates (measured in ug/m3)
  • Volatile Organic Compounds (Chemical Pollutants)
  • Temperature
  • Relative Humidity
  • Carbon Dioxide (CO2)
  • Carbon Monoxide (CO)
  • Extensive system and sensor diagnostics to catch potential sensor anomalies.
  • 30-minute placement for automatic IAQ report and long-term report if desired.
  • Standalone monitor without the need for connected mobile devices.
  • Formaldehyde and PM2.5 firmware upgrades are scheduled to be released in 4Q,2016 / 1Q,2017
  • Training on IAQ fundamentals, monitor usage and report interpretation
User Comments
  • “Energy Smart Home Performance utilizes Air Advice Indoor Air Quality monitors to begin to narrow in on Indoor Air Quality (IAQ) problems. We find their report to be particularly useful and readable by laypeople and pros alike.” - Energy Smart Home Performance

Cube Sensors

Cube Sensors

The Cube Sensor is an indoor air quality and environmental monitor that has recently been sold out (we think it is being sunsetted in favor of the Koto, but that’s not entirely clear). It is small (2x2x2 in), and can be deployed in an integrated fashion in multiple locations throughout a building. This room-to-room analysis capability is probably the cube’s most attractive feature, as cube bundles offer an opportunity for a more comprehensive building analysis (for a reasonable price). Despite currently being sold out, there is a chance to pre-order a similar device (called Koto) on its webpage to get a comparable experience. 

Pricing
  • $139.00
  • Status: Currently Sold Out (Sales to Reopen?)
Features
  • Complete with 5 sensors that can detect the following:
  • Particulates (Dust & Other Allergens)
  • Volatile Organic Compounds (Including CO)
  • Temperature (°F)
  • Humidity (%)
  • Carbon Dioxide (CO2)
  • Other Non IAQ features include:
  • Light detection
  • Noise detection
  • Bluetooth
  • Offline storage of data
  • Operation: Wireless connectivity; syncs with mobile devices
User Comments
  • “We were surprised by just how useful the CubeSensors were. In retrospect it's obvious environmental factors are as important to how you feel as your own body metrics, but it was interesting to see (and feel) the real world changes that could be experienced by acting on the CubeSensors' advice.” - Simon Crisp, gizmag.com
  • “However, the Cube Sensors are not without issues. The big one being that information is currently only available for the previous 24 hours. This means you can't easily see if a change in habit is having the desired effect on your environment over a period of time.” - Simon Crisp, gizmag.com
