Airthings Wave Radon Review: Easy, Accurate Continuous Radon Monitoring
A battery-powered smart radon detector with temperature and humidity, wave-to-check and an app history, let down by Bluetooth-only sync and weak support.
The Airthings Wave Radon is a popular, easy way to monitor radon continuously instead of relying on one-and-done test kits. It tracks radon plus temperature and humidity, shows trends and history in a clean app, and has a wave-to-check gesture that lights a green, yellow or red ring. Owners find it accurate enough, with readings that line up with professional lab tests after a 48-hour acclimation and that clearly respond when a mitigation fan is switched on or off. It runs on batteries (lasting years), is portable, and can link to an Airthings hub over SmartLink for better battery life and weekly reports. The main drawbacks: it is Bluetooth-only, so it only syncs when you open the app nearby (no Wi-Fi), Airthings customer support is widely criticized as slow and chat-only, and a minority report inconsistent readings or occasional false spikes. For peace of mind in a basement or crawlspace, it is a solid, well-reviewed choice.

Pros
- Continuous radon monitoring with app history and trends, unlike one-time kits
- Accurate enough to match professional lab tests after a 48-hour acclimation

- Battery powered (lasts years) and portable between rooms and floors
- Also tracks temperature and humidity; works with Google, Alexa, Home Assistant and IFTTT
- Can join an Airthings hub over SmartLink for better battery life and weekly reports
Cons
- Bluetooth only: syncs when you open the app nearby, no Wi-Fi or background sync
- Airthings customer support is slow, chat-only and hard to reach
- A minority report inconsistent readings or occasional false high spikes
- Needs a 48-hour acclimation before readings are reliable
- Hub setup takes some networking know-how
- No Apple HomeKit, SmartThings or Matter
Who is the Airthings Wave Radon for?
This is a smart radon detector for homeowners who want ongoing radon readings rather than a single mail-in test. It measures radon along with temperature and humidity, runs on batteries (no cord, so you can move it between rooms and floors), and connects over Bluetooth to a free app that shows current levels, history and trends. A wave of your hand lights a colored ring (green, yellow or red) for an at-a-glance status. It works with Google Home, Amazon Alexa, Home Assistant and IFTTT (there is no Apple HomeKit, SmartThings or Matter), and can join an Airthings hub over SmartLink for longer battery life and weekly email reports. It best suits anyone concerned about radon in a basement, crawlspace or ground-floor room, people validating or tracking a radon mitigation system, and existing Airthings owners building out a multi-room setup.
What buyers love
The biggest win is continuous, trackable data. Owners repeatedly contrast it with one-time charcoal kits, valuing the app history that shows how radon rises and falls with weather, rain, an empty house or a closed-up home. Accuracy gets strong support: several compared it against professional 48-to-72-hour lab tests and short-term kits and found it close after the recommended 48-hour acclimation, and many describe watching levels drop off a cliff into the green after installing or restoring a mitigation fan, which convinced them it genuinely works. The wave-to-check ring is praised as quick and intuitive, setup is called a one-minute job (batteries plus app), battery life lasts years, and the Bluetooth range is good enough to check from elsewhere in the house. Owners also like adding it to an Airthings hub via SmartLink for better battery life and weekly reports, and several credit it with catching a disrupted mitigation system before it became a problem.
What to know before you buy
Two caveats come up often. First, it is Bluetooth-only: it does not have Wi-Fi and only updates the app when you open it within range, rather than syncing in the background, so some owners wish for built-in Wi-Fi (Airthings sells pricier display/Wi-Fi models, or you can add a hub). Second, Airthings customer support is widely criticized as chat-only with long delays (often 24 hours or more between replies), scripted, and prone to ghosting, which makes warranty claims frustrating. A minority of owners also report inconsistent readings or occasional false high spikes (one tied to high humidity that needed a periodic power-cycle, another where two units a few centimeters apart disagreed), so for peace of mind it is worth confirming against a lab test at least once. Remember the 48-hour acclimation period before trusting the first numbers, and note that setting it up with a hub takes a little networking know-how.
Is the Airthings Wave Radon worth it?
For continuous radon monitoring, yes: it is an easy-to-use, well-reviewed detector that gives you trends and peace of mind a single test kit cannot, and owners find it accurate enough to validate professional tests and to confirm a mitigation system is working. It is especially worthwhile if you have a basement or crawlspace, or want to keep an eye on an existing mitigation setup. Go in knowing it is Bluetooth-only (so syncing means opening the app nearby, or adding a hub), that support is poor if something goes wrong, and that you should cross-check against a lab test once. If you want hands-off Wi-Fi readings and a display, step up to a pricier Airthings model; if you want a simple, portable, accurate radon tracker, this delivers.
Frequently asked questions
Is the Airthings Wave Radon accurate?
Owners generally find it accurate enough: several compared it with professional 48-to-72-hour lab tests and short-term kits and saw close agreement after the recommended 48-hour acclimation, and many watched levels drop after installing a mitigation fan. Cross-checking against a lab test once is still wise.
Does it have Wi-Fi?
No. It connects over Bluetooth only and syncs to the app when you open it within range, rather than in the background. If you want hands-off remote readings, add an Airthings hub (the device can link over SmartLink) or choose a pricier Airthings model with Wi-Fi and a display.
How does the wave-to-check feature work?
Wave your hand over the device and it lights a ring green, yellow or red to show your radon status at a glance, without opening the app. For exact numbers and history you check the free app over Bluetooth.
How long does the battery last, and is setup hard?
It is battery powered and owners report years of life. Setup is quick, roughly a minute after installing the app and inserting the batteries. Adding it to an Airthings hub for weekly reports and better battery life takes a little more networking know-how.
What does it measure besides radon?
Along with radon, it tracks temperature and humidity, all viewable with history in the app. It does not measure other pollutants like CO2, VOCs or particulates; Airthings' higher-end monitors add those.
