Hello there,
In this Instructable I will walk through how I built a simple air filter fan to help remove smoke and other particles from the air while I’m soldering.
If you want to build one, read on, I hope to make it simple and easy.
I’ll note here before we get too far that this filter while it does work to remove the small amount smoke from soldering I would not expect this to be a replacement for proper ventilation.

I have linked all the parts I used, however some are left from older projects.

None of these links are affiliate links so I make nothing from them. If you want to support me directly you can do so here.
