Airthings Wave Plus Review: Six-Sensor Air Quality and Radon, on Bluetooth
Radon, CO2, VOCs, temperature, humidity and pressure in one popular monitor, with a great app, but Bluetooth-only sync and questionable radon precision.
The Airthings Wave Plus is the popular six-sensor monitor that combines radon with CO2, VOCs, temperature, humidity and air pressure. It is a favorite for getting a full picture of indoor air quality, with VOC and CO2 readings that respond quickly to ventilation, cooking or bringing stored items inside, and many owners credit it with revealing a radon problem and prompting them to install mitigation. It keeps history from day one, has a clean app and a useful web dashboard, a wave-to-check Good/Fair/Poor light, and a magnetic mount, and runs on batteries. The catches: it is Bluetooth-only (no Wi-Fi), so it needs an Airthings hub for continuous, remote data, the app and syncing are slow and sometimes unreliable, and its radon precision is debated, with several owners finding it reads low versus charcoal lab kits. As a long-term air-quality trend monitor, it is well-liked; for precise radon specifically, cross-check with a lab kit.
- All-in-one air quality plus radon

- Home Assistant and Homebridge users
Pros
- Six sensors in one: radon, CO2, VOCs, temperature, humidity, pressure
- Responsive VOC and CO2 readings that reflect ventilation and activity

- Wave-to-check Good/Fair/Poor light and a magnetic mount; battery powered
- Helps confirm a radon problem and track a mitigation system
- Works with Google Home, Alexa, Home Assistant and IFTTT (and Homebridge with effort)
Cons
- Bluetooth only: needs an Airthings hub for continuous, remote data
- App and syncing are slow and sometimes unreliable
- Radon precision is debated; several found it reads low vs lab charcoal kits
- Needs a 7-day (ideally 30-day) calibration; slow to adjust when moved
- No mold detection (the Wave Mini has it) and no particulate sensing
- No Apple HomeKit, SmartThings or Matter
Who is the Airthings Wave Plus for?
This is a comprehensive six-sensor air quality monitor for people who want radon alongside the rest of the picture. It measures radon, CO2, VOCs, temperature, humidity and atmospheric pressure, shows a Good/Fair/Poor light when you wave at it, and feeds a clean app and web dashboard with long-term history. It connects over Bluetooth only (no Wi-Fi), runs on batteries, and mounts magnetically, so you can move it between rooms. To get continuous recording and remote access you need an Airthings hub; on its own it logs when you open the app nearby. It works with Google Home, Amazon Alexa, Home Assistant and IFTTT (and, with effort, Homebridge), but not Apple HomeKit, SmartThings or Matter. It best suits anyone wanting one device for radon plus air quality, people tracking long-term trends or a mitigation system, and smart-home tinkerers who want the data in Home Assistant. Treat it as a trend tool that needs a 7-day calibration, not an instant reader.
What buyers love
Owners value getting six measurements in one good-looking, battery-powered unit. The VOC and CO2 readings are praised as responsive, visibly changing when you sweep the floor, open a window, or carry in boxes from storage, which helps people understand and improve their ventilation. Many bought it specifically for radon and credit it with confirming a problem (often alongside another monitor) and justifying a mitigation system, with several calling it potentially life-saving. The app and web dashboard are well-liked for clean presentation and history from day one, including naming and comparing rooms, and the wave-to-check light plus magnetic mount are handy touches. Temperature and humidity track closely with thermostats, battery life is good, and several owners highlight responsive Airthings support. Tinkerers also appreciate getting it into Home Assistant or Homebridge.
What to know before you buy
Two issues come up repeatedly. First, connectivity: it is Bluetooth-only, so it needs an Airthings hub (an extra cost) for continuous recording and remote access, and the app and syncing are widely described as slow and flaky, sometimes showing days-old data and needing many sync attempts before it uploads, which owners blame on Airthings' cloud infrastructure rather than their own network. Second, radon precision is debated: several owners testing it against charcoal lab kits and a RadonEye found the Wave Plus reading low (by up to a full point or more), was slow to adjust when moved, and even showed different numbers on two phones at once, and noted radon mitigation companies trust charcoal tests over these monitors. As a result, treat radon readings as a ballpark trend and confirm with a lab kit if precision matters. It needs a 7-day (ideally 30-day) calibration, does not detect mold (the Wave Mini does), measures CO2 not CO, and lacks particulate sensing. There is no Apple HomeKit, SmartThings or Matter.
Is the Airthings Wave Plus worth it?
For an all-in-one look at your indoor air, yes: it is a popular, capable monitor that combines radon with CO2, VOCs and the basics, has a strong app and history, and genuinely helps people improve ventilation and decide on radon mitigation. It is especially worthwhile if you want long-term trends and one device covering several pollutants. Just go in knowing it is Bluetooth-only (so budget for a hub if you want remote, continuous data), that the app and syncing can be frustrating, and that its radon numbers are best treated as a trend and cross-checked against a lab kit. If you need precise radon specifically, pair it with a charcoal test or choose a radon-focused monitor; if you want a broad, well-liked air-quality monitor, the Wave Plus delivers.
Frequently asked questions
What does the Wave Plus measure?
Six things: radon, CO2, VOCs, temperature, humidity and air pressure. Note it measures CO2 (carbon dioxide), not CO (carbon monoxide), and it does not detect particulates or mold (the Wave Mini has a mold-risk indicator).
Does it have Wi-Fi?
No. It is Bluetooth-only, so it records and syncs when you open the app nearby. For continuous recording and remote access from anywhere, you need to add an Airthings hub, which is an extra purchase.
Is its radon reading accurate?
It is debated. Several owners comparing it with charcoal lab kits and a RadonEye found it read low (sometimes by a full point or more) and was slow to adjust, and noted mitigation companies prefer charcoal tests. Treat its radon as a ballpark trend and cross-check with a lab kit if precision matters.
Why is the app slow to update?
Because it syncs over Bluetooth, the app can show days-old data until it connects, and owners report needing several sync attempts before it uploads to the cloud, which they attribute to Airthings' infrastructure rather than their own internet. A hub improves continuous data.
How does it compare to the View Plus?
The Wave Plus has the same core sensors as the View Plus minus particulates, but it is Bluetooth-only with no display, whereas the View Plus adds Wi-Fi, an e-ink screen and a PM2.5 sensor and can act as a hub. Choose the Wave Plus for a cheaper six-sensor monitor, the View Plus for built-in Wi-Fi and particulates.
