When you're comparing indoor air measurement options, the first question is usually whether you need radon detection, CO2 and PM2.5 tracking, or all of them. The choices here range from a compact handheld particle checker to a multi-parameter radon monitor, so the right answer depends on what you actually want to measure. The Airthings 2960 is the only one that tracks radon plus CO2, VOC, and PM2.5, while the Temtop P600 focuses on PM2.5 and PM10, and the open-box Wave Plus leans into smart-home integration with radon detection. Two entries for the Airthings 2960 appear here with the same title but different prices, so we've treated them as the same monitor with a price gap.
At a glance: price comparison
| Product | Price | Price bar |
|---|---|---|
| Temtop P600 Air Quality Monitor Particle Detector PM2.5 PM10 Recorder Histogram | USD 69.99 | |
| Airthings Wave Plus 2930 Air Quality Monitor | USD 89.00 | |
| Airthings 2960 Radon Air Quality Monitor CO2 VOC PM2.5 WiFi Battery | USD 200.00 | |
| Airthings 2960 Radon Air Quality Monitor CO2 VOC PM2.5 WiFi Battery | USD 225.00 |
The spread from cheapest to most expensive is about $155, with the Temtop at the bottom end, the Wave Plus $19 higher, and the two Airthings 2960 units well above both.
How to choose
| If your priority is... | Recommended pick |
|---|---|
| One multi-parameter home monitor | Airthings 2960 (lower-priced new unit) |
| Smart-home automation and remote monitoring | Airthings Wave Plus 2930 |

Airthings Wave Plus 2930 Air Quality Monitor
If you want an indoor air monitor that works with your smart-home setup, this open-box Wave Plus is the one. It detects radon and connects over Bluetooth and Wi-Fi, with remote monitoring and compatibility with IFTTT, Amazon Alexa, and Google Home. The white unit weighs 0.84 lb and is 4.75 inches in diameter. It takes two batteries, and they are not included. The trade-off is that this model does not cover CO2, VOC, or PM2.5, so it's really a radon-focused smart monitor rather than a full air quality station.
Airthings 2960 Radon Air Quality Monitor CO2 VOC PM2.5 WiFi Battery (lower-priced new unit)
This new Airthings 2960 is the most comprehensive all-in-one option in this set. It pairs radon detection with CO2, VOC, and PM2.5 measurement, and because it runs on battery power with Wi-Fi, you can place it where you need it without hunting for an outlet. This version is the lower-priced of the two 2960 entries, so it gives you the full feature set without the additional cost attached to the higher-priced unit. If you want one device that covers radon plus the other common indoor pollutants, this is the one to start with. The main limitation is that it is still a significant step up from the entry-level options here, so you are paying more for that extra sensor coverage.
Airthings 2960 Radon Air Quality Monitor CO2 VOC PM2.5 WiFi Battery (higher-priced new unit)
The higher-priced Airthings 2960 entry provides the same radon, CO2, VOC, and PM2.5 monitoring, the same Wi-Fi connectivity, and the same battery-powered design as the lower-priced version. If you're comparing the two directly, the lower-priced unit gives you the identical feature set for less, so this option makes sense only if you prefer this particular new-condition unit or if the price difference doesn't matter to you. In terms of capabilities, you get the full multi-parameter air picture in one device, which is the main reason to consider it. The limitation is that it costs more than the other 2960 option in this comparison.
Temtop P600 Air Quality Monitor Particle Detector PM2.5 PM10 Recorder Histogram
The Temtop P600 is the lowest-priced monitor in this group and the only one built around particle detection. It measures PM2.5 and PM10, shows color-coded air quality levels on its display, and records the last 12 hours as a histogram so you can see trends. It's handheld, includes a back stand for indoor or outdoor use, and has a 3000mAh battery that provides 8 to 9 hours of standby after a 3 to 4 hour charge. The trade-off is that this model doesn't detect radon, CO2, or VOCs, so it's not a replacement for the Airthings monitors if you need those measurements. Instead, think of it as a fast, low-priced particle checker for spot checks around the home or office.
Final recommendation by use case
- For whole-home coverage: choose the lower-priced new Airthings 2960 at USD 200.00. It does more in one battery-powered WiFi unit than the others here.
- For smart-home integration and remote monitoring when you want to spend less: choose the Airthings Wave Plus 2930 at USD 89.00, and keep in mind it needs batteries and offers a narrower set of measurements.
- For quick particle-level checks with a clear histogram: choose the Temtop P600 at USD 69.99 if particles are your main concern.
- If you're deciding between the two Airthings 2960 options, go with the USD 200.00 version; the USD 225.00 option offers the same feature set.
