Wave Plus

Why we tested it

We focused on the Airthings Wave Plus because it addresses the invisible hazards of indoor living. While many monitors track basic temperature or humidity, this device stands out by integrating professional-grade radon detection alongside CO2 and VOC sensors. Radon is a leading cause of lung cancer, yet it remains largely ignored in standard home maintenance. By combining these critical health metrics into a single, battery-powered unit, Airthings provides a comprehensive solution for homeowners concerned about long-term air quality. We wanted to see if its Bluetooth-enabled ecosystem truly simplifies the complex task of monitoring air health without requiring constant manual intervention or complicated wiring setups.

Who it's for

This monitor is ideal for homeowners in regions with high radon risk or those living in older, tightly sealed properties where ventilation is a concern. It is perfect for parents, remote workers, or health-conscious individuals who want data-driven insights into their indoor environment. However, those seeking a device that integrates seamlessly with Apple HomeKit or SmartThings should look elsewhere, as compatibility is currently limited. If you are looking for a simple, set-it-and-forget-it solution to track air quality trends over time, this is a top-tier choice, but casual users who do not care about radon may find the price point steep.

Real-world performance

In practice, the Wave Plus excels at providing granular data through the Airthings app. The setup is straightforward, and the device operates quietly in the background. Users report that the CO2 sensor is particularly effective at identifying when a room requires better ventilation, which often correlates with improved focus and sleep quality. While the Bluetooth-only connection means you must be within range to sync data, the historical logging within the app is robust and easy to interpret. The visual indicator—a simple wave of the hand triggering a green, yellow, or red light—is a clever, intuitive feature for quick checks. Overall, the sensor accuracy is highly regarded, making it a reliable tool for those who prioritize health data over complex smart home automation.
