AirThings View Plus Review: The Best All-in-One Indoor Air Quality Monitor for Homeowners

The AirThings View Plus is the consumer continuous indoor air quality monitor that has become the de-facto choice for homeowners who want broader IAQ visibility than a radon-only device provides. It measures seven parameters (radon, PM2.5 particulate, CO2, total VOCs, humidity, temperature, atmospheric pressure) and reports through a polished phone app and an e-ink display on the device itself. For homeowners in EPA Radon Zone 1 (which includes essentially the entire U.S. Front Range Colorado region) the radon measurement alone justifies the device; the IAQ data on top is bonus visibility into the air people are actually breathing day-to-day. This review walks through what the device does well, where its limitations are, and who should or should not write the check.

Methodology: this review is based on publicly available AirThings specifications, ATSDR and EPA documentation on the parameters measured, and synthesis of consumer feedback from documented sources. The InspectandTest editorial team has not physically tested this unit. Where we cite specific performance characteristics they come from AirThings published documentation.

What it is

The AirThings View Plus is a desktop or wall-mountable consumer IAQ monitor approximately 6 inches wide and 2 inches deep, powered by six AA batteries (rated 18 months) or USB-C. It uses a passive alpha-particle spectrometer for radon, a laser scattering sensor for PM2.5, NDIR (nondispersive infrared) for CO2, and a metal-oxide sensor for total VOCs. Data displays on the device’s e-ink screen plus the AirThings phone app, which provides historical trend graphs and configurable alerts.

Specifications at a glance

Strengths

Broadest IAQ coverage in the consumer category. Most competitive monitors measure 2 to 4 parameters; the View Plus measures 7. For households interested in indoor air quality holistically (not just one isolated concern), the breadth is meaningful.

App quality is genuinely good. Trend graphs are readable, alerts are configurable, multi-device dashboards work well. AirThings has invested in software and it shows. This is meaningfully better than the apps from RadonEye, Ecosense, and most direct competitors.

Smart-home integration is real. AirThings supports IFTTT, Home Assistant, and several other ecosystems via API. Triggering ventilation when CO2 rises or notifications when radon spikes works without significant configuration friction.

Battery life is honest. The 18-month rating is real-world achievable. Many users report longer in mild climates with stable use patterns.

E-ink display reduces friction. Glanceable readings on the device itself mean residents check IAQ without having to open the app, which builds the habit of paying attention.

Limitations

VOC sensor is qualitative, not quantitative. The metal-oxide VOC sensor reads “total VOCs” as a single number that does not distinguish between toxic compounds (formaldehyde, benzene) and harmless ones (cooking aromatics, perfume). Useful as a relative indicator of “something is off-gassing” but not as a chemistry-specific readout.

CO2 sensor reads only NDIR-detectable concentrations. NDIR is the standard residential CO2 measurement and is reliable in the range that matters (400 to 2,000 ppm), but it does not measure carbon monoxide (CO), which is a different molecule with different health implications. Many homeowners conflate the two.

Pricing premium versus single-purpose devices. If you only care about radon, the AirThings View Radon at $179 measures the same radon parameter at the same accuracy. The View Plus premium is paying for the additional five parameters. Whether that is worth $120 depends on whether you want the broader data.

Wi-Fi sometimes drops. Documented user complaints about needing to reconnect the device to Wi-Fi after router changes or extended power outages. Once configured the device runs reliably; the setup friction is occasionally meaningful.

Not a life-safety device. No CO sensor, no smoke detection, no alarming designed for emergency response. Maintain dedicated CO and smoke alarms; use the View Plus alongside them.

Who it is for, and who it is not

Buy it if: you live in EPA Radon Zone 1 and want both radon and broader IAQ visibility; your home has had recent renovation or new furniture (VOC tracking is most useful in the first months after off-gassing sources are introduced); you have respiratory-sensitive household members for whom PM2.5 visibility matters; you operate a home office where CO2 tracking informs ventilation; or you are a working home inspector who wants a single device that gives client talk-tracks beyond just radon.

Skip it if: you only care about radon (the View Radon is the better-value choice at $179); you already have a multi-sensor smart-home system that includes IAQ (some premium systems do); you want a life-safety device (this is not one); or you want lab-grade scientific accuracy (the consumer-grade sensors are good for tracking but not for legal or insurance documentation).

Comparison vs alternatives

Verdict

The AirThings View Plus earns a 4.3 out of 5. It is not the lowest-cost option for any single parameter, and the VOC sensor’s qualitative-only output is an honest limitation rather than a deal-breaker. For households in radon-prone regions who want the broadest practical IAQ coverage in one device, this is the right pick. The 18-month battery life, the genuinely good app, and the smart-home integration combine to make this a device that gets used rather than installed and forgotten. The premium over the radon-only View Radon is worth it if you want the broader data; not worth it if you only care about radon.
