Managing flux and solder steam and smoke.

The best approach is to solder in a vented hood so all the vapor is vented outside. Most people don't have access to one and for small soldering jobs I don't take any venting precautions. If you're going to do a lot of soldering you might consider doing it outside or at least in the garage (if you have one) with all the doors open.

I like the smell of burning flux myself, but if you're really worried about it then just wear a respirator. If you're using lead free silver bearing solder then don't even bother with that unless allergies or asthma are an issue.

We have a good sized three stage HEPA filter ( two layers of foam with varying density, a carbon based filter for odor control and then the HEPA filter ) directly behind our work benches at the shop. This helps draw the solder smoke away from us as we work.

Other than that, soldering in a well ventilated area is the first and most obvious suggestion. Placing a box fan directly in front of you but behind the work surface and having it draw air away from you will help break up the smoke so that it is not so concentrated. This works much better than having the fan blowing at the work surface as that tends to cool the solder iron / gun too much and the solder joints may not set up correctly. Sean

Thanks gents for participation!
I'm OK with odor from flux but I'm skeptical to lead-free labels on tin/silver solder and tend not to believe entirely that it's true becides vapors from are basically as harmful.
Since I live in appartment building I've arranged the stairwell area for my new DIY project where basically if you're smoking you can see that smoke comes up to the vent shaft real fast and straight.
