Short answer: take the Wave Plus if radon is a realistic concern where you live, because no other sensor here measures a hazard that accumulates silently over years. Take the Wave Enhance for a bedroom or home office above ground, where noise, light and carbon dioxide are the things actually affecting sleep and concentration.
What Each Listing States
| Item | Wave Plus | Wave Enhance |
|---|---|---|
| Radon | Yes, continuous long-term measurement | No |
| CO2 | Yes | Yes |
| VOC | Yes | Yes |
| Humidity, temperature, pressure | Yes | Yes |
| Noise | No | Yes |
| Light | No | Yes |
| Connectivity | Bluetooth to the Airthings app | Bluetooth to the Airthings app |
| Quick check | Wave in front for a colour-coded indication | Not stated in the bullets |
A Hazard Sensor and Comfort Sensors
Radon is different in kind from everything else either device measures. It is a health risk that accumulates over years of exposure, it produces no symptoms you would notice, and there is no way to detect it without an instrument. Carbon dioxide, noise and light are comfort and performance parameters. High carbon dioxide makes people drowsy and is fixed by ventilation. Noise and light affect sleep quality. None of them will harm you over a decade the way radon can.
So the first question is geographic and structural rather than about features: is radon plausible in your house? A basement, a slab on grade in a known radon area, a sealed crawlspace or simply a region with elevated soil radon all say yes, and then the Wave Plus is the device.
The Sleep Argument for the Wave Enhance
The Wave Enhance listing makes a specific case: high carbon dioxide indicates insufficient ventilation, which harms sleep at night and concentration during the day. Adding noise and light to that gives you the three measurable things that determine whether a bedroom is a good place to sleep. It is a coherent product idea, and for an upstairs bedroom in a house with no radon concern it is more useful day to day than the Wave Plus.
Treat the VOC Reading as an Indicator
Both devices report VOCs, and both describe them as airborne gases from sources such as cooking, fumes and cleaning products. These sensors report an index across a broad mixture rather than a concentration of any named chemical, so use the number to notice change rather than to judge a level. A spike after cleaning or after new furniture arrives is the sensor working correctly. See VOC versus TVOC.
Put Them in Different Rooms
These two devices genuinely belong in different places. A radon monitor belongs in the lowest occupied level, because radon comes from the ground and is highest there. A sleep and concentration monitor belongs where you sleep and work. If you are buying one of each, this is not redundancy; it is two instruments in the two rooms where their measurements mean something.
Who Buys Which
- Basement, slab, crawlspace or radon-prone region: Wave Plus.
- Upstairs bedroom or home office: Wave Enhance.
- Poor sleep with no obvious cause: Wave Enhance, for CO2, noise and light together.
- Wanting particulates and WiFi as well: the View Plus.

Frequently Asked Questions
Does the Wave Enhance measure radon?
No. Its listing states five always-on sensors covering CO2, VOC, humidity, temperature and pressure, plus noise and light tracking. Radon is the Wave Plus feature.
What is the light sensor for?
Sleep and circadian rhythm. Light levels in a bedroom at night and in a workspace during the day both affect how people sleep and concentrate, which is the use case the Wave Enhance listing describes.
Do both need the app?
Both are app-based Bluetooth devices. The Wave Plus listing states you can wave in front of it for a colour-coded visual indication, or connect by Bluetooth for detail.
Which is better for a bedroom?
The Wave Enhance, unless your bedroom is in a basement or a radon-prone area, in which case radon monitoring during the eight hours you spend asleep matters more than noise data.
