2026 verdict
Wi-Fi and a screen, or three extra sensors?
The Airthings 2989 View Radon is the better radon monitor of these two Airthings models, because it reports over Wi-Fi and shows its readings on an E-Ink display. It also runs up to 3 years on six AA batteries or on USB-C power, against 1.5 years on two AA cells for the Airthings Wave Plus, which has no screen and needs an Airthings hub before it can send data while you are away. The Airthings Wave Plus answers with a broader sensor set: CO2, TVOC and air pressure on top of the radon, temperature and humidity both measure. Both carry a 5-year warranty and work with Google Home, Alexa and Home Assistant. Pick the Airthings 2989 View Radon for hands-off radon alerts from anywhere, and the Airthings Wave Plus if ventilation and VOCs matter as much as radon.

What the differences mean
Remote access
The Airthings 2989 View Radon joins your Wi-Fi, so readings and alerts reach your phone wherever you are. The Airthings Wave Plus is Bluetooth only: without an Airthings hub it updates only when you open the app nearby.
What it measures
Both track radon, temperature and humidity. The Airthings Wave Plus adds CO2, TVOC and air pressure, which is what tells you when a bedroom needs airing or when cooking and cleaning fumes build up. The Airthings 2989 View Radon sticks to radon.
Reading it at a glance
The Airthings 2989 View Radon has an E-Ink screen with the numbers on it. The Airthings Wave Plus has no screen, only a light you wave at for a good, fair or poor reading, so the detail lives in the app.
Power
Six AA batteries give the Airthings 2989 View Radon up to 3 years, and it also takes USB-C power. The Airthings Wave Plus runs on two AA cells for about 1.5 years and has no wired option.
Which one to buy if
- you want radon alerts while you are away from home
The Airthings 2989 View Radon is on Wi-Fi, so it needs no hub to push alerts and weekly reports.
- you also want to know when a room needs fresh air
The Airthings Wave Plus measures CO2 and VOCs, which the Airthings 2989 View Radon does not.
- the monitor goes in a basement next to an outlet
The Airthings 2989 View Radon can run on USB-C and skip battery changes entirely.
- you already own an Airthings hub
The hub gives the Airthings Wave Plus the remote access it lacks, leaving its extra sensors as the deciding factor.

What owners say
Owners of both Airthings monitors use them the same way: as a trend tool that exposes how radon swings with weather and season and that confirms a mitigation system is doing its job, and both groups suggest checking against a lab test once. Airthings 2989 View Radon owners single out checking levels and getting alerts from anywhere, the weekly email reports and a unit that flagged a failed mitigation fan, while their complaints are about a minority of defective units and Airthings support that ranges from generous to scripted. Airthings Wave Plus owners talk about CO2 and VOC readings that move when a window opens or a floor is swept, and complain about slow, flaky Bluetooth syncing and radon readings that several found lower than charcoal lab kits.
