Airthings Wave Plus Review: Radon, VOC and Indoor Air Tracking

The Wave Plus was the first consumer monitor to put radon and CO₂ in the same battery-powered device. It is still one of the few that does. This review explains what each sensor delivers and where the screenless, Bluetooth-only design limits it.

Verdict

The Wave Plus remains a sensible choice for a household that wants radon and ventilation data from a single battery-powered unit and does not need a screen. Six measurements, a free app and a wave-to-check indicator cover the essentials. The compromises are the lack of a display, the lack of a particle sensor, and Bluetooth-only connectivity unless you add a hub. For most homes the question is whether to spend more for the View Plus, which fixes all three.

Radon and CO₂ in One Device

The two gases answer different questions. Radon is a long-term exposure issue that varies with soil, season and pressure. CO₂ is a short-term ventilation indicator that varies with occupancy. Having both in one unit is convenient because the fix for both is often the same: more fresh air. The app shows both histories, and owners often notice that the radon long-term average and the overnight CO₂ peaks both improve after ventilation changes. Background on both is in choosing a radon monitor and what is a good indoor CO₂ level.

Sensor Notes

  • Radon: provisional for the first days, settles over weeks. Long-term average is the decision number.
  • CO₂: NDIR, so a real ventilation measurement. Sampling interval on battery is longer than on a mains-powered monitor, so fast events are smoothed.
  • VOCs: relative index. Useful for spotting cleaning products and new furnishings, not for identifying compounds.
  • Pressure: helps explain radon swings; falling pressure often draws more soil gas into a basement.

Strengths

  • Only a handful of consumer devices combine radon and NDIR CO₂ on batteries.
  • Free app with history and reports.
  • Quiet and dark at night; suitable for bedrooms.

Limitations

  • No display; the indicator is a colour only.
  • No particle sensor.
  • Remote access needs a hub.

How It Compares

The View Plus adds a screen, PM2.5 and Wi-Fi at a higher price. The Wave Enhance drops radon and adds a noise sensor at a lower price. The Corentium Home 2 is radon-only with a display. The Wave Plus sits in the middle of the range and is the value option when you want both gases.

How We Research

Frequently Asked Questions

Does the Wave Plus measure particles?

No. PM2.5 is only on the View Plus in the Airthings range.

How do I see the readings?

Wave a hand in front of the unit for a colour indicator, or open the Airthings app over Bluetooth for the numbers and graphs.

Can it send alerts when I am away?

Only if it is connected to the cloud through an Airthings hub or a View-series device on USB power. On its own it syncs when the phone is in range.

How long do the batteries last?

Airthings quotes battery life in the range of a year and more on two AA batteries depending on settings.
