This Airthings View Plus review finds an easy-to-set-up monitor that tracks radon, particles, CO2 and VOCs in one device, and LeafScore, a home and sustainability review site whose reviewer Dan ran it in his New York home, named it its top overall pick for indoor air quality.
Here is how setup went, what the readings showed in a real home, how it compares with other Airthings models, and what it costs as of October 21, 2026.

Airthings View Plus review: what is in the box
LeafScore’s reviewer found the Airthings View Plus packed in recyclable cardboard with the monitor, a USB-A to USB-C cable, adhesive pads, a quick start guide and a small desiccant pack. There is no power adapter, so plan to use your own. The unit has mounting holes on the back but no screws or anchors, which he said cost a couple of dollars at a hardware store.
Setup
Pull the activation strip to connect the battery, then install the Airthings app and make an account. The app found the monitor over Bluetooth almost instantly, the reviewer says. The monitor shows a six-digit pairing code, then you connect it to Wi-Fi. He described the whole process as fast and simple.
How long until readings
The radon, CO2 and VOC sensors collect baseline data first; LeafScore got first readings after about three days. The app then said radon would need about 27 more days to become more accurate, so expect about a month before relying on the radon number.
What it measures
- Radon: LeafScore calls radon a carcinogen that seeps from the ground and recommends every property have a detector. The app alerts you if levels become concerning when notifications are on.
- PM2.5 and PM1: His PM2.5 jumped from about 5 to 35 while baking with an electric oven, and he received an alert; he expects a gas range would read higher.
- CO2: The monitor showed consistently high CO2 in summer with his air conditioning running, which he had not realized and planned to address.
- VOCs: Spikes from paint, stains or harsh cleaners show up here.
- Humidity, temperature and pressure: His humidity averaged 51 percent. Pressure has no warning levels since it is not a hazard, he notes.
- Pollen: The app shows local pollen by location.
The app
Each reading has its own chart with three-hour, 24-hour, seven-day, 30-day and one-year views, color-coded green, yellow and red. LeafScore received alerts when readings went red but did not see one for a yellow VOC spike, and planned to check whether alerts can be set for yellow.
The display
By default the screen shows radon and PM2.5, and you can customize which readings appear. Wave your hand over the front and it shows a second reading with a colored light: green when everything is in range, red when something needs attention. His lit red for CO2. Airthings lists a 2.9-inch display.
Build and power
The reviewer found it sturdy, with a hard plastic body and a rubber band on the base for tables. Airthings says it can run on six AA batteries for up to two years in low-power mode, or plug in over USB-C. The View Plus also connects over Wi-Fi and acts as a hub for battery-powered Airthings Wave monitors, so you can add a Wave Plus in a basement or bedroom.
Airthings View Plus vs Wave Plus
The Airthings Wave Plus measures radon, CO2, VOCs, humidity, temperature and pressure but has no particle sensor and no screen, according to Airthings. It costs less and runs about 1.5 years on two AA batteries. If smoke and cooking particles matter to you, the View Plus is the one to get.
Smart home and placement tips
Home Assistant has an Airthings integration for the company’s Wi-Fi monitors, so the View Plus readings can drive automations such as turning on a fan when CO2 climbs. For placement, LeafScore’s experience suggests keeping it in a main living area: his kitchen activity showed up as particle spikes even with an electric oven, which is useful if you want to know when to run a range hood or purifier. LeafScore notes radon seeps up through the foundation, so a basement or ground-floor room makes sense if radon is your main concern.
Price
Amazon lists the Airthings View Plus at $329.99 as of October 21, 2026. That is more than CO2-only monitors such as the Aranet4, but those do not measure radon or particles.
Who it is for
- Homes with basements or ground-floor bedrooms where radon is a concern.
- People who want one device for particles, CO2 and VOCs instead of several sensors.
- Anyone adding Airthings Wave monitors in other rooms, since the View Plus acts as their hub.
