A small trashbin and a Paps fan
Smoking solder is not a very healthy addiction 🙂  The fumes contain stuff that is not good for your health. Especially the solder that contains lead.  How bad it is, I have no clue. I read that lead in solder is only harmful above a temp of 500C. But it does irritate my nose/lungs. I use a full size table fan to blow the smoke away towards an open window.  That works very well but in winter to cold and when it rains also not a good idea (a 19″ rack holding my calibrators and time standards is placed partial in front of that window)
I used a small garbage-bin. The fan is a 12V Paps fan. This has a good air flow and is not to noisy. Â Inside is a well breathing bag that was used to store a ski-goggle. I filled it with active carbon granulate used in aquarium filters. The bag is located under the grid you see on top. It rests on a coarse carbon filter (also from an aquarium filter).

The solder-iron is about 15cm away from the fan. You see the smoke is sucked in.  I do not see smoke coming out the “chimney” top.
This was usable but I was not satisfied about the ease of use. The next one I made from a powerfull 230V fan that was used for cooling a frequency converter in a machine but they are also used in bathrooms. The housing is made with a 3D printer. I use a footswitch to operate it. I bought carbon filters from Farnell and that worked better for the airflow as the granulate. They are just a bit bigger but easy to cut and they are cheap too. (Duratool , 130x130x10, partnumber 1391657)
The housing front looks a bit weird but was designed with a sort of overhanging top and I stopped the printing before that was finished.
