Radon is an invisible threat, and the Airthings Wave makes it visible. This detector moves beyond the single-use test kit by providing continuous monitoring through a simple, battery-powered device. You get a living picture of your home’s air, not just a one-time snapshot.

The Wave sits quietly on a shelf, running for over a year on two AA batteries. Its real intelligence is in the app, which graphs your radon, temperature, and humidity levels day by day. You can see how levels change with the seasons or after you open windows. The data is clear, actionable, and free from lab fees or subscriptions.

Setup takes minutes. The trade-off for this convenience is patience; it needs at least 30 days of data to establish a reliable long-term average. For ongoing peace of mind in the one area a standard smart home system overlooks, it’s a definitive tool.
