Inside air quality is a growing concern to many people, and a part of the “Internet of Things” that has recently heated up is the monitoring of that quality. Today we’re looking at Airthinx IAQ, a professionally-oriented air quality monitoring system that includes a hardware monitor with a built-in 3G cellular modem for connectivity, a web-based dashboard that can be used to monitor multiple homes or offices, and an iOS app for on-the-go insights.


To begin with, let’s talk about the actual monitoring device. It’s a compact  wall-mounted box approximately 4.13 x 2.5 x 1.13 inches in size, powered by a dedicated USB 5V power supply that plugs into the bottom. Once attached to the wall and plugged in, the IAQ monitor requires no other setup. When purchased, the monitor’s serial number is connected to your account and the device begins sending out air quality information the moment it’s connected to power.

There’s a LED strip near the top of the device that shows general air quality by glowing green, yellow or red. During the entire time I tested the Airthinx IAQ monitor, it went between yellow — indicating moderate air quality (apparently below 90 on a scale between 0 and 100) — and red, which indicates poor air quality. Turning off visual alerts using the app turned the LED strip to blue, and there’s also a setting for device status that can be used to turn the LED strip completely off — useful if the IAQ monitor is being installed in a bedroom.

The Airthinx website dashboard (see image above) is quite clean and easy to read, and provides detailed minute-by-minute tracking of air quality for any site being monitored. With a click on any of the air quality factors being monitored, they appear or disappear from the chart. It’s also possible to view the data as a table and download the data in a .csv file format for further analysis.

It’s also possible to set up alerts with the system to send an email to a system subscriber. For example, I set up an alert for “poor air quality” whenever AQ is less than 70. 

Likewise, there’s an iOS app (iPhone only) that can be used to track air quality when you’re away from a computer. It’s quite well written, easy to use, and fast. Indicators that are red and yellow show when a particular factor is either borderline or outright poor. For example, the app showed a red dot near the humidity reading. Well, I live in Colorado where low humidity is quite common, so the 19.2% reading is nothing that I’m particularly worried about. 


Set up of the system is incredibly simple thanks to the built-in cellular modem. There’s absolutely no need to connect the Airthinx IAQ monitor to your Wi-Fi network. However, I did run into some issues in setting up an account with Airthinx as I have a non-standard email address using the domain. Once I changed to a more standard email address, everything worked well. There was also a bit of a discrepancy between what worked for login with the web-based dashboard and the app. The Airthinx support team provided almost immediate support via online chat.

Compared to my other air quality monitoring device — the $199 AWAIR 2nd edition (read review here) , the Airthinx device is quite a bit more “industrial looking”. The AWAIR comes in a wood case that is attractive, it has a display on the front so users don’t need to look at a web dashboard or app to monitor the air quality, 

However, we’re really talking about two different markets here. Airthinx is obviously pointing this toward those who wish to monitor multiple sites at once. For a facilities manager with a large company with multiple offices, it would be useful to install Airthinx IAQ monitors at those locations to keep an eye on the air quality to prevent employee lawsuits due to sick building syndrome. AWAIR is oriented towards those who are concerned about air quality in the home.

Airthinx also provides a much more complete picture of air quality, with twelve separate factors being monitored on the dashboard: VOC (volatile organic chemicals), PM10 (particulate matter between 2.5 and 10 micrometers in diameter), PM 2.5 (fine particles between 2.5 micrometers or less), two other particulate matter readings (PM1 and PM), temperature in both °F and °C, a composite air quality index (AQ), humidity, CH2O (formaldehyde, a common toxin), CO2 (carbon dioxide level), and air pressure. 

It’s fascinating to watch the changes in the various factors during the day.  For example, the PM readings always spike shortly after one of my cats visits the litter box, an indication that has me switching to a more dust-free litter. Temperature, air pressure and humidity of course fluctuate as the day passes, but what could have caused a sudden bump in formaldehyde three times during the last week? A quick look at weekly readings in the app indicated that these bumps coincided with cooking in my house. 

Of course, monitoring moderate to poor air quality is of no use if you don’t do something about it. In my case, I’ve decided to add cat-safe plants throughout the house that can help trap and eliminate toxins, do the aforementioned change to dust-free cat litter, and — when weather permits — open windows during cooking.

One oddity that showed up has to do with the device’s location awareness. I may be wrong, but it appears that the IAQ doesn’t use GPS, instead relying on either cellular or Wi-Fi-based location. As a result, the device consistently showed its location as outside of the house across the street. It would be more useful if the dashboard could use a set street address as a location, or use GPS location.

Pricing on the device runs $49 monthly for a two-year minimum lease, or $699 for an outright purchase, both of which include the built-in 3G coverage. Enterprise plans are also available with customized service plans, volume discounts, consulting, customized APIs, and more. 


The Airthinx IAQ is a powerful and easily setup air monitor that is perfect for facility managers who wish to keep a close eye on air quality in buildings that they manage. While the price of the device is somewhat prohibitive to the average user, the IAQ provides much more data that can be acquired through a less expensive device and offers flexibility in sending alerts.
