2026 verdict
Radon and a five-year warranty, or a big color screen?
The Airthings View Plus is the stronger air quality monitor overall, with battery power, Alexa and Google Home support and more alert types. The IQAir AirVisual Pro fights back with a 5 inch color LCD readable across the room, PM10 and PM1 measurement and a display that shows indoor and outdoor air side by side. The Airthings View Plus measures radon, PM2.5, CO2, TVOC and pressure and runs about 2 years on 6x AA batteries, while the IQAir AirVisual Pro lasts about 4 hours cordless. Pick the Airthings View Plus for whole-home monitoring and voice control, and the IQAir AirVisual Pro for an always-visible readout in a room you check by eye.

What the differences mean
Sensors
The Airthings View Plus adds radon and atmospheric pressure to PM2.5, CO2, TVOC, temperature and humidity. The IQAir AirVisual Pro adds PM10 and PM1 particle sizes but no radon, which matters in a house with a basement.
Screen
The IQAir AirVisual Pro has a 5 inch color LCD that you can read from across a room. The Airthings View Plus has a 2.9 inch E-Ink screen, unlit, that shows two chosen values and a wave-to-check indicator.
Power and portability
The Airthings View Plus runs about 2 years on 6x AA batteries, or on USB-C. The IQAir AirVisual Pro lasts about 4 hours on its built-in battery and charges over Micro USB, so it is really a plugged-in device.
Smart home reach
Both support Home Assistant. The Airthings View Plus adds Alexa and Google Home, while the IQAir AirVisual Pro has neither, and neither supports Apple Home or Matter.
Alerts and warranty
The Airthings View Plus sends temperature, humidity, air quality and low battery alerts and carries 5 years of warranty. The IQAir AirVisual Pro sends air quality alerts only, with 1 year of warranty.

What owners say
Owners of both monitors say they trust the readings: Airthings View Plus owners cross-checked PM2.5 against outdoor reference sensors and radon against traditional tests, and IQAir AirVisual Pro owners report PM2.5 and CO2 matching Dyson units, ecobee sensors and nearby government stations. They part ways on what they value. Airthings View Plus owners praise the app and web dashboard with CSV export, months of battery life and how fast CO2 builds in a sealed bedroom, and complain about the price, a CO2 sensor that drifts high until it gets fresh air and fixed alert thresholds. IQAir AirVisual Pro owners love the big screen with outdoor air next to indoor, and complain that the displayed index uses PM2.5 only, the CO2 sensor takes about three days to settle, the internal battery is weak and support was unhelpful when a unit stuck at zero.
