Review: Great little device - Wow this thing is great. Shows all kinds of graphics for the air quality and temps and humidity for my house. Wife has been concerned about the air quality in general and this gives us more reassurance. No cords or anything necessary since it runs on a rechargeable batter that lasts a while. Great value for the cost and it’s convenient to bring when we travel too.
Review: Always good to monitor your air quality - I’ve been using this air quality monitor mainly to keep an eye on air quality while 3D printing, and it’s been really solid so far. Setup was quick, basically turn on and good to go. and the display is bright, clear, and easy to read from across the room. It tracks CO2, PM2.5, PM10, and overall AQI, which is super helpful to see how things change during and after a print. The readings seem accurate and respond quickly when the printer starts running or when I open a window for ventilation. It’s nice having actual data instead of just guessing if the air’s getting stuffy or dusty. For anyone doing a lot of 3D printing or working in a small workshop, this little monitor gives some good peace of mind. Big plus it has USB-C charging port!

### ⭐⭐⭐⭐ Useful and apparently accurate
*by H***Y on October 19, 2025*

This seems to be a useful and accurate tool, and I especially appreciate the CO2 monitoring. I find myself opening a window more often when the level is high. I run my air purifier less often -- only when the particulate level rises. I have no idea how accurate it is, but it is responsive, for example, to ordinary cooking fumes or burning incense. It's fairly easy to set up, and I recommend calibrating the CO2 level manually, as the instructions suggest.
