Short answer: the View Plus is the only one of the two that measures radon and carbon dioxide, and those are the two parameters most worth acting on. The H5106 is the better buy if particulates are the specific question, and several of them can cover more rooms than one View Plus.
What Each Listing States
| Item | Airthings View Plus | GoveeLife H5106 |
|---|---|---|
| Radon | Yes | No |
| CO2 | Yes | No |
| PM2.5 | Yes | Yes, accuracy plus or minus 15 micrograms per cubic metre |
| VOC | Yes | No |
| Temperature and humidity | Yes | Yes, with stated accuracy |
| Pressure | Yes | No |
| Connectivity | WiFi, app and account required | 2.4 GHz WiFi for the clock |
| Refresh | Not stated in the bullets | Two second correction interval |
One Good Monitor or Three Cheap Ones
This is the question most people should actually be asking. Indoor air is not uniform. Carbon dioxide is high in a closed bedroom and normal in a hallway. Particulates spike in a kitchen and settle elsewhere. Radon is highest at the lowest level. A single monitor, however good, reports one location.
So if your interest is particulates specifically, several inexpensive monitors placed in the kitchen, the bedroom and the living room will teach you more about your house than one premium device in the hall. If your interest is radon, none of that applies: you need the instrument that measures it, and you need it in the right room.
Radon Is the Argument for the View Plus
Every other parameter here can be sensed by a human in some crude way. You notice a stuffy room, you smell cooking smoke, you feel damp air. Radon gives you nothing. It is the one measurement where the instrument is not confirming an impression but supplying information you could not otherwise have, and that is what justifies the price difference for households where radon is plausible.
Published Figures Deserve Credit
The GoveeLife listing publishes an accuracy figure for each of its three parameters. That is more transparency than most air quality products offer, including the View Plus bullets. It does not make the cheaper device more capable, but it does mean you know what you are getting, and a stated uncertainty is more useful than an unstated one however good the brand.
Who Buys Which
- Radon-prone region or basement living space: View Plus.
- Cooking smoke, candles, wildfire season: H5106, perhaps more than one.
- Ventilation and stuffiness: View Plus, or a dedicated CO2 monitor.
- Whole house understanding on a budget: several cheap monitors plus one radon detector beats one of everything.

Frequently Asked Questions
Does the H5106 measure CO2 or radon?
No. It states PM2.5, temperature and humidity only. Carbon dioxide and radon require different sensors, and the View Plus includes both.
Which publishes accuracy figures?
The H5106, which states plus or minus 15 micrograms per cubic metre for PM2.5, plus or minus 0.54 F for temperature and plus or minus 3 percent relative humidity. The View Plus bullets do not publish per-sensor accuracy.
Is one View Plus better than several cheap monitors?
It depends what you want to know. Radon needs one monitor in the right place. Particulates and carbon dioxide vary room to room, so several inexpensive monitors can tell you more about your house than one expensive one in the hall.
Does the View Plus work without WiFi?
The listing states the monitor requires the Airthings app to function and that an account is required, so it is designed as a connected device.
