A number on a screen, and what it does and does not tell you · review
A seven-sensor Wi-Fi monitor covering radon, PM2.5, CO2, VOCs, humidity, temperature and air pressure, read through the Airthings app. Radon is sampled with a passive diffusion chamber and alpha-spectrometry detection; the unit runs on AA batteries or USB and can act as a hub for other Airthings devices.
The bottom line The View Plus covers more ground than anything else in this family — radon and VOCs on top of CO2 and particulates — and it's priced accordingly. It's built around Airthings' app and account system rather than a standalone display, so it suits someone monitoring a whole home over time more than someone who wants a quick number to check on a shelf.
Airthings lists seven always-on sensors in the View Plus: radon, particulate matter (PM2.5), CO2, VOCs, humidity, temperature and air pressure. That’s the widest sensor set confirmed in this family — the other three monitors here measure at most three of those seven. Readings surface on a customisable e-ink screen on the device itself, and in more detail through the Airthings app.
Airthings describes the radon sensor as a passive diffusion chamber paired with alpha-spectrometry detection — a different measurement approach from the CO2 or PM2.5 sensors, and one that inherently needs longer sampling windows to stabilise into a reliable reading, since radon levels are typically assessed as an average over time rather than a single instant. Airthings doesn’t publish the underlying CO2 sensor technology (NDIR or otherwise) for this model, which is a gap compared with the SwitchBot and Temtop monitors in this family that do state their CO2 sensor type.
Airthings states that an account and the app are required for the View Plus to function — this isn’t an optional smart-home add-on the way SwitchBot’s Hub is, but a stated requirement for using the device. In exchange, the app handles notifications, trend history and, per Airthings’ listing, local pollen forecasts sourced from Breezometer. The e-ink display on the unit itself shows current readings without opening the app.
The View Plus ships with six AA batteries and runs on Wi-Fi rather than Bluetooth alone, so it’s reporting to the app continuously rather than needing a phone nearby. Airthings’ listing also describes an optional wired mode: connect the View Plus by USB cable and it can function as a hub, simplifying setup for other Airthings monitors in the same home. Registering the device on Airthings.com extends the standard warranty to five years at no extra cost.
Unlike every other monitor in this family, the same ASIN (B097YW5Q72) was confirmed present on all six marketplaces checked — Germany, France, Italy, Spain, the US and the UK — with prices across the four EU markets clustering around 220–270 €. It’s also the most expensive monitor confirmed in this family, by a wide margin over the CO2-only displays.
The View Plus is built for someone tracking air quality across a whole home over time, not for a quick glance at one number. Its case is the sensor count — radon and VOCs on top of CO2 and PM2.5 — and its cost is the app/account requirement plus the highest price point in this family.

The device has its own e-ink display for at-a-glance readings, but Airthings states an account and the app are required for the monitor to function — notifications, trend history and full sensor data go through the app.
Airthings doesn't publish the underlying CO2 sensor technology for the View Plus in the listings checked, unlike some other monitors in this family that state NDIR explicitly.
Yes — the ASIN B097YW5Q72 was confirmed present on all six marketplaces checked (Germany, France, Italy, Spain, the US and the UK), which isn't the case for every monitor in this family.

The View Plus covers more ground than anything else in this family — radon and VOCs on top of CO2 and particulates — and it's priced accordingly. It's built around Airthings' app and account system rather than a standalone display, so it suits someone monitoring a whole home over time more than someone who wants a quick number to check on a shelf.
Whole-home air monitoring where someone wants radon and VOC coverage alongside CO2 and particulates, and is comfortable running everything through the Airthings app.

NDIR sensor · ±50 ppm accuracy · Bluetooth + app
A Bluetooth CO2, temperature, and humidity monitor built around a Swiss-made NDIR sensor, refreshing readings every second with a claimed ±50 ppm accuracy. The large display works standalone; alarms, app notifications, and the full 6-in-1 screen need a separate SwitchBot Hub 2.
Best for: Someone who wants a stated NDIR accuracy figure and is willing to add a SwitchBot Hub 2 later for app alerts and automation.
≈ 50 €
CO2 + PM2.5/PM10 · NDIR + laser sensor · rechargeable
A handheld multi-pollutant monitor combining an NDIR CO2 sensor with a laser particle sensor for PM2.5 and PM10, alongside temperature and humidity. Readings show on a colour TFT screen, with an audio alarm and CSV export over USB — no Wi-Fi or companion app.
Best for: Anyone who wants CO2 and particulate readings together in one portable unit, and is comfortable exporting data manually rather than watching it in an app.
≈ 160 €
0–3000 ppm CO2 · LED traffic-light · USB powered
A pocket-sized, USB-powered CO2 display with a three-colour LED traffic light (green/yellow/red) and an alternating CO2/temperature readout. No app, no Bluetooth, no battery to replace — just a plug-in monitor for a single room.
Best for: A single room where someone wants a plain go/no-go ventilation cue — a bedroom, home office, or classroom — without setting up an app.
≈ 35 €
