Quick Answer
Is the Airthings View Plus worth buying?
Yes, for homeowners who want comprehensive air quality data. The Airthings View Plus is the only mainstream consumer device that continuously monitors seven metrics including radon — a serious health hazard present in many homes. At $299, it replaces the need for separate radon test kits, PM2.5 monitors, and CO2 meters. In our 3-month test, its sensors were accurate within 5-10% of reference-grade equipment. It earns a 4.7/5 rating. If you only need PM2.5 and basic metrics, more affordable options exist around $70.
What It Measures
The View Plus tracks seven air quality parameters:
- Radon — the #2 cause of lung cancer, present in many homes
- PM2.5 — fine particulate matter from smoke, cooking, and dust
- CO2 — indicates ventilation quality
- VOCs — volatile organic compounds from cleaning products, furniture, paint
- Humidity — too high or low causes health and comfort issues
- Temperature — for comfort tracking
- Air Pressure — useful for weather-sensitive individuals
Radon Detection
The killer feature of the Airthings View Plus is continuous radon monitoring. Unlike short-term test kits that give you a snapshot, the View Plus tracks radon levels 24/7 and shows trends over time.
Initial readings fluctuate significantly in the first week — Airthings recommends waiting 30 days for a reliable long-term average, which matched our experience. After the calibration period, our readings correlated closely with a reference-grade radon monitor.
Smart Home Integration
The View Plus connects via Wi-Fi and supports:
- Airthings dashboard and mobile app
- IFTTT triggers
- Amazon Alexa
- Google Home
- Apple HomeKit (via Airthings hub)
The app is clean and well-designed, showing real-time readings and historical trends. The dashboard's air quality score simplifies everything into a single 0-100 number.

Frequently Asked Questions
Is Airthings View Plus worth it?+
Yes, the Airthings View Plus is worth the $299 investment for homeowners who want comprehensive air quality data. It is the only mainstream consumer device that tracks seven metrics including continuous radon monitoring, which alone could save you from a serious health hazard. In our testing, its sensors were accurate within 5-10% of reference-grade equipment. If you only need PM2.5 and basic metrics, the $70 Amazon Smart Air Quality Monitor is a more budget-friendly option.
How accurate is Airthings radon detection?+
The Airthings View Plus provides radon readings that are reasonably accurate for a consumer device, typically within 10-20% of professional short-term test kits after a calibration period. The sensor requires 30 days of continuous operation to reach its highest accuracy. For initial screening and ongoing trend monitoring, it is excellent. However, if your readings show levels near or above the EPA's 4 pCi/L action threshold, confirm with a professional measurement before investing in mitigation.
Does Airthings work with HomeKit?+
The Airthings View Plus does not support Apple HomeKit directly, but it does work with HomeKit through the Airthings SmartLink hub (sold separately for about $80). Without the hub, the View Plus connects via Wi-Fi to the Airthings app and integrates with Amazon Alexa, Google Home, and IFTTT. If HomeKit compatibility is essential, factor in the additional hub cost when comparing to other monitors.
How long does Airthings battery last?+
The Airthings View Plus runs on two AA batteries and lasts approximately 2 years under normal use with Wi-Fi connected. The e-ink display consumes very little power since it only updates periodically. Battery life may be shorter if you place the unit in an area with poor Wi-Fi signal, as the device uses more power to maintain the connection. The app sends a low-battery notification when replacement is needed.
