Data from the official Airthings and Aranet sites.
2026 verdict
Six tracked sensors against one untracked hazard, and the scoreboard favors the Airthings Wave Plus, which wins on warranty plus a wider connectivity, integrations, sensors and alerts lineup built on its radon, CO2, VOC, temperature, humidity and pressure readings. The Aranet Radiation comes back with a lower price, a higher owner rating, a longer battery life and its e-ink screen (the Wave Plus has no display), but its actual specialty does not show up anywhere on this table: it measures ionizing radiation dose rate and total dose, not radon or CO2, so the sensors row is really comparing a six-pollutant monitor against a category this air-quality-monitor schema does not track at all, not ranking radiation accuracy. Both are battery-powered and Bluetooth-only, so neither offers Wi-Fi or remote alerts without extra hardware. If you want one device covering radon alongside CO2, VOCs and the rest, the Airthings Wave Plus is the broader instrument; if radiation specifically is the concern, it is the Aranet Radiation you need, since the Wave Plus has no way to detect it.

Frequently Asked Questions
Which is better overall: Airthings Wave Plus or Aranet Radiation?
The Airthings Wave Plus wins overall on warranty, connectivity, integrations, sensors and alerts, thanks to its six-sensor suite covering radon, CO2, VOCs, temperature, humidity and pressure. The Aranet Radiation costs less, holds a higher owner rating and lasts longer on a battery, but measures a different hazard.
What is the biggest difference between the Airthings Wave Plus and the Aranet Radiation?
Scope. The Airthings Wave Plus packs six sensors, radon, CO2, VOCs, temperature, humidity and pressure, into one unit. The Aranet Radiation focuses on a single hazard, ionizing radiation dose rate and total dose, and has none of the Wave Plus's other sensors.
Does the Airthings Wave Plus detect radiation?
No. Despite its broad six-sensor suite, it has no ionizing-radiation sensor. Anyone who wants radiation monitoring specifically needs a dedicated device like the Aranet Radiation.
Do either of these have Wi-Fi?
No, both connect over Bluetooth only. The Airthings Wave Plus needs an Airthings hub for continuous, remote data, and the Aranet Radiation relies on Home Assistant for anything beyond checking the app nearby.
Who should buy the Airthings Wave Plus?
Choose it if you want one device covering radon alongside CO2, VOCs, temperature, humidity and pressure, with support for Google Home, Alexa, Home Assistant and IFTTT.
Who should buy the Aranet Radiation?
Choose it only if background ionizing radiation, not radon or general air quality, is what you want to monitor continuously. Its lower price, higher owner rating and longer battery life do not extend to any of the Wave Plus's six sensors.
