Choosing an environmental indoor air measurement setup starts with deciding which pollutants actually matter in your home. Some monitors focus on carbon dioxide, others add VOCs, PM2.5, temperature, humidity, and even radon. The four listings here span a wide price range, from an open-box model to a brand-new unit that costs more than double, and not all of them track the same things. The Airthings 2960 appears in two listings, so the comparison is really three distinct models with one model offered at two prices. Here's how to sort through the options.
Quick take
If radon is your main concern, the Airthings 2960 is the one that explicitly adds radon to CO2, VOC, and PM2.5 tracking, but it comes with the highest prices here. If you want smart home integration on a smaller budget, the Airthings Wave Plus 2930 offers remote monitoring and works with Alexa, Google Home, and IFTTT, but it's an open-box unit with no batteries. If you prefer a new, compact monitor for CO2, TVOC, and particulate matter, the AirSense8 sits in between with a visual alarm.

The bar length below shows the listed price for each option.
| Monitor | Listed price | Price bar |
|---|---|---|
| Airthings 2960 (higher listing) | USD 225.00 | |
| Airthings 2960 (lower listing) | USD 200.00 | |

Decision matrix
| Monitor | Best for | Watch out |
|---|---|---|
| Airthings 2960 (both listings) | Radon plus CO2, VOC, and PM2.5 in a battery-powered WiFi monitor | Highest outlay, even at the lower of the two listings |
| Airthings Wave Plus 2930 | Smart home users who want remote monitoring on a lower budget | Open box with no batteries included |
| AirSense8 | Compact CO2, TVOC, and particulate tracking with a visual alarm | Does not cover radon |
Product notes
Airthings 2960 Radon Air Quality Monitor CO2 VOC PM2.5 WiFi Battery
This monitor shows up twice in this comparison: one listing at USD 225.00 and another at USD 200.00 for the same new-in-original-packaging unit. If radon detection is your priority, this is the model that calls it out by name, and it also tracks CO2, VOC, and PM2.5. The battery-powered design and WiFi connectivity make it easy to place in a room and keep an eye on readings. On the downside, even the $200 listing carries the highest price among these four options, so it is meant for someone who wants radon and broader pollutant coverage in one device. The two listings give you a price choice if you shop around.
Airthings Wave Plus 2930 Air Quality Monitor
The Wave Plus 2930 is the budget pick at USD 89.00, but the condition is open box and no batteries are included. It still stacks up well on features: it offers remote monitoring and works with IFTTT, Amazon Alexa, and Google Home, so you can ask your smart assistant about indoor air. It is a white radon detector with a 4.75-inch diameter, making it a compact addition to a shelf or side table. The main limitation is that it arrives opened and repacked, so you may want to inspect it on arrival and plan to supply your own batteries before you can start monitoring. If you want smart home controls without the top-of-range price, this is a strong candidate.
Air Quality Monitor Indoor - CO2 Detector, VOC Meter and AQI Tester Tracks TVOC
At USD 117.32, this new AirSense8 monitor covers a different set of concerns than the Airthings models. It continuously tracks CO2, TVOC, and particulate matter, including PM2.5 and PM10, with temperature and humidity sensors. The visual alarm gives you an at-a-glance warning when readings climb, and the compact 3.74-inch square body is easy to tuck into a home office. It includes a USB Type-C charging cable, so you can keep it powered from a device body. The limitation is that it doesn't mention radon detection, so if radon is your main worry, you would need to look at the Airthings units instead.
Final recommendation by use case
Pick the Airthings 2960 if you need radon detection; the lower of its two listings is the smarter way to get the same hardware. Pick the Airthings Wave Plus 2930 if you want smart home compatibility and are comfortable with an open-box unit that needs batteries. Pick the AirSense8 if you want a new, compact monitor for CO2, VOCs, and particulate matter without paying for radon coverage.
