2026 verdict
Seven sensors versus a single untracked one, and it is the Airthings View Plus that wins this comparison overall, leading on warranty plus a wider connectivity, integrations, sensors and alerts lineup thanks to Wi-Fi, cloud sync and readings for radon, PM2.5, CO2, VOCs, temperature, humidity and pressure. The Aranet Radiation costs less, holds a higher owner rating and runs longer on a set of batteries, but none of the View Plus's seven sensors, and none of the fields on this air-quality-monitor comparison table, actually measure what the Aranet Radiation is built for: ionizing radiation dose rate and total dose. That means the sensors category score genuinely reflects the View Plus tracking more of the pollutants this schema checks for, not that the Aranet Radiation is a lesser device outside its own specialty. Both use an e-ink display for at-a-glance readings, so the two are more alike on the shelf than in what they are actually detecting. Pick the Airthings View Plus for comprehensive indoor air quality including radon; pick the Aranet Radiation only if background radiation is the specific hazard you are watching, since the View Plus offers no way to measure it.

Frequently Asked Questions
Which is better overall: Airthings View Plus or Aranet Radiation?
The Airthings View Plus wins overall on warranty, connectivity, integrations, sensors and alerts, thanks to its seven-sensor suite covering radon, PM2.5, CO2, VOCs, temperature, humidity and pressure over Wi-Fi. 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 View Plus and the Aranet Radiation?
Scope. The Airthings View Plus is the most complete Airthings monitor, combining radon with PM2.5, CO2, VOCs, temperature, humidity and pressure over Wi-Fi. The Aranet Radiation is a single-purpose dosimeter tracking ionizing radiation dose and total dose over Bluetooth, with none of those other sensors.
Does the Airthings View Plus detect radiation?
No. Even with seven sensors covering radon, particulates, CO2 and VOCs, it has no ionizing-radiation sensor. Anyone who specifically wants radiation monitoring needs a dedicated device like the Aranet Radiation.
Which one offers remote, Wi-Fi access?
Only the Airthings View Plus, which connects over Wi-Fi in addition to Bluetooth and syncs to the cloud for remote alerts and a web dashboard. The Aranet Radiation is Bluetooth-only, so remote access means routing it through Home Assistant.
Who should buy the Airthings View Plus?
Choose it if you want comprehensive indoor air quality monitoring, radon included, with Wi-Fi, an e-ink display, and 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 View Plus's seven sensors.
