Update 1
Hello everyone
I have noticed that the fan is not generating enough airflow, or at least not working at the maximum possible performance.
As I am a fan of major hardware I remembered the following episode:
Is this CHEATING? - Fan Showdown S3E3 - YouTube #cheaterftw
I applied the principles to the filter, and lo-and-behold, more airflow, less noise.
The grille is OK in its original state, but makes a noise.
When using the stator, the grille can be snipped away with a flat side cutter.
All models updated in a pressure profile distributed over 4 plates
STORY:
I was concerned with the air quality in my small hobby room. The latest studies and measurements show that microparticles, VOCs and formaldehyde also escape into the room during PLA and PETG printing.
Here is one of many YouTube videos about this:

Part of the problem can be improved with a recirculating air filter. These things are expensive and I tend to be cheap.
I still had 2 5V 120mm Noctua fans from an old project.
An air improver is really just a filter with a fan. Done...
I don't really need a PM2.5 or PM10 measuring device, what's important to me is low power consumption for 24/7 operation.
That's how I came up with the idea for this bad boy.
The Cheap Air Purifier:
The fan has a clamp fit and always stays in place. I secured it with a little hot glue.
The cable can be connected to the USB-C charging controller using a plug or directly. A little bit of soldering is required.
The USB-C connection and the cable can then also be glued in with hot glue.
The fan cover has a clamp fit on the air filter from Xiaomi (or one of their imitators)
The base is optional for the look.
Finished.
Connect the USB charging cable and let it run.
