Spending on a home air monitor usually starts with one question: what exactly are you trying to catch? Maybe it's radon drifting into the basement, or maybe it's the fine dust and particles from cooking, candles, or pollen. These two options for environmental indoor air measurement approach that job in very different ways.
Quick verdict
If you want steady radon awareness with smart-home access, the Airthings Wave Plus 2930 is the easier pick. It monitors for radon and can be integrated into smart-home routines for hands-free updates. If you want hard numbers on particles, the PM0.3/2.5/10 dust particle counter is the better fit. It gives live PM0.3, PM2.5, and PM10 readings and logs trend history. The trade-off is in the listed prices: the particle counter is $159.99, the Wave Plus is $89.00, a $70.99 difference.

Where each monitor wins
The Airthings Wave Plus wins for everyday connected air awareness. It is built around radon, a concern that often needs a dedicated detector. Because it supports remote checks and common smart-home assistants, you can stay informed from another room or while away, and you can fold the monitor into simple automations.
The PM0.3/2.5/10 dust particle counter wins for precise particle data. It uses laser scattering to separate three particle sizes, so you can see whether the issue is fine dust, PM2.5, or larger PM10 particles. The trend history and adjustable alarm make it useful for tracking changes after cooking, cleaning, or ventilating a room.
Product notes
Air Quality Monitor, PM0.3/2.5/10 Dust Particle Counter, High Sensitivity 3-Chan
This unit is the closest thing to a particle-focused instrument in this pairing. The laser sensor reports PM0.3, PM2.5, and PM10 with ±12 µg/m³ accuracy, while also keeping an eye on temperature and humidity. That makes it a good match for a workshop, a home office, or a room where cooking and dust are the main concerns. It stores 999 timestamped readings and shows them as a trend chart, so you can look back at how a space changed through the day instead of relying on a single snapshot. The adjustable audible alarm adds a useful warning when levels cross the limit you set. The limitation is scope: this is a dedicated air particle counter, not a connected radon monitor. If radon or voice-control routines are your priority, the Airthings Wave Plus is the one to choose.
Airthings Wave Plus 2930 Air Quality Monitor
The Wave Plus is the better choice when you want a monitor that sits quietly in a room and reports back to you. It is a radon-focused unit with Bluetooth and Wi-Fi connectivity, so you can keep an eye on conditions from another floor or while you are out. The smart-home side covers Amazon Alexa, Google Home, and IFTTT, which means the monitor can fit into existing routines and give you voice-accessible updates. Just note the condition: this unit is open box, opened, tested, and repacked, and it ships without batteries. You will want two batteries on hand before setup. For someone who wants continuous radon awareness and easy remote access, this is the simpler, lower-stress path.
Final choice by use case
Choose the Airthings Wave Plus 2930 if radon is your main worry, you already use a smart assistant, or you simply want remote air monitoring without studying a screen. Choose the PM0.3/2.5/10 dust particle counter if you need to know exactly what particle sizes are in your air and want to track them over time. Both are legitimate tools for environmental indoor air measurement; they just point you toward different questions.
