Deciding which environmental indoor air measurement tool belongs in your home can feel like picking between a single-purpose sensor and a full dashboard. The $89 Airthings Wave Plus 2930 combines radon detection and smart-home connections in a small white disc, while the $30 16-in-1 Air Quality Monitor puts a 7-inch display and nine AQI parameters on your countertop. Your call comes down to whether you want a connected radon-focused sensor or a broader, glanceable screen.
If you're trying to compare them directly, think about how you'll use the monitor day to day. The Wave Plus is a small, connected device that can sit on a shelf and send information to your phone. The 16-in-1 is more of a kitchen-counter display, showing CO2, PM2.5, humidity, and other values on a large screen. The price difference is $59, and that gap tracks the difference in approach: one is a sensor you talk to, the other is a screen you look at. The Wave Plus also carries a radon sensor, which is a distinctive addition if that gas is a concern in your area.
Quick verdict
Choose the Airthings Wave Plus if you want a small monitor. Choose the 16-in-1 Air Quality Monitor if you want a fuller set of indoor air readings with sound alerts.

Product notes
Airthings Wave Plus 2930 Air Quality Monitor
The Airthings Wave Plus 2930 is a small white monitor with a 4.75-inch diameter and 0.84 lb weight, so it can sit on a bookshelf or end table without taking over. The listing notes that no battery is included, so you will need to supply two batteries. Choose it if you want a compact sensor you can set in a corner and forget about. Its limitation is the battery requirement, which adds a small step before you can use it. The white finish blends easily with existing decor, and the open-box condition means the unit has been opened, tested, and repacked.
16-in-1 Air Quality Monitor
The 16-in-1 Air Quality Monitor presents its readings on a 7-inch display, making it easy to see what's in the air at a glance. The unit is described as new - open box. If you want a clear on-device readout for the whole family, this is the easy pick. The tradeoff is that it relies on being within view, so it is less useful when you are away from the room. For a busy kitchen or living area, you get a quick readout without opening an app. It also includes time, so the display can serve as a clock while it monitors the room.
Final choice by use case
- For a neat, unobtrusive addition to a shelf: Airthings Wave Plus 2930.
- For a central, easy-to-read station: 16-in-1 Air Quality Monitor.
