I ripped a 120v 3x6 inch fan assembly off a rack of medical equipment and bought a sheet of activated carbon filter foam stuff whatever and wrapped the assembly in it.
Ugly but works well and is cheap.
Will pull fumes from about 3 ft away laterally.
One day I'll pretty it up a bit and put it on a slide out hinge assembly also stolen from medical scap so I can hide it under the shelf.
I know this doesn't help much but there's really not much to those guys. A fan and filter substrate.
Stick a vortex fan on some PVC in the rafters blowing through some filter and run a 2 inch vacuum tube down to the desk. 600 cf/m of extraction and the noise is across the room. It'll probably clean the snipped leads off you desk too!
I’ve been looking into attaching my laser Machine’s hose/fan that extracts fumes out my window to my desktop Fa400 since I noticed with the sun shining in that the room is full of smoke, probably don’t have lead poisoning?
I used a little personal fan to blow the fumes away and t worked alright, but there'd be backdrafts and, especially working on an amp, it wasn't really something I could move around to different areas effectively.
I've only been able to use it once, but it is a massive upgrade. You can move the hose wherever you want and the instructions said that there are longer hoses available. The hose also stays put wherever you move it. It was really handy working on my amp because I could move it in, out, and around all over the place. I wish I'd bought one for myself sooner, it would have been well worth the money.
You can see it peeking out from under my lamp here:
I bought a 6" fan, something like Erik's, some flexible tubing and was going to hang it from the joists above my bench (basement solder-station) and run the tube out the window, simply remove one of the little basement windows replace it with plywood to which the hose would be fastened.
Problems.
1) Wife does her gardening in front of the window so all the lead-fumes would coat her gardening stuff.
2) Would need to work out some quick-change system for the window in winter.
3) Need a way to stop critters (squirrels, mice, voles, bugs etc) from crawling through the tube into the nice warm house.
4) I'm lazy, bought the stuff, haven't set it up yet; but now I won't due to problems 1 & 5.
5) Adopted a dog that runs through the yard, problem 5 is now problem #1.
Currently using a large desk-fan to extract fumes away from me, but I solder in the furnace room, so all I'm doing is getting the fumes away from my immediate work area,
where they then get redistributed throughout the house by the furnace poisoning my wife and dog, and me, still. See problems 1&5.
I posted this recently somewhere else in the forum, but can't find my post — nonetheless, here 'tis, a DIY fume-extractor article by The Tone God:
How To Build A Solder Fume Extractor Introduction Fumes given off when soldering are not good for one’s health. One solution is to use a solder fume extractor. The problem is that fume extractors are either hard to get or are somewhat expensive. This article is to show you how to build a solder...

There were some extractor suggestions in this thread (just 3 pgs):
Just curious what you would tell someone just getting started in pedal building to buy with a $100 Amazon gift card? I just placed a big Tayda order so I should be good on most parts. What about tools or specialty parts?

From that thread, Harry Klippton pointed out the lead doesn't make it into the fumes, but rosin-fumes aren't worth huffing either.
[EDIT Here's the desk fan, it gets moved onto the solder bench to the right (where the computer is in the pic) when soldering. Furnace is behind and to the left]
I have this. As far as “extraction” goes its useless, but its nice to keep flux smoke out of my nose. I mostly bought it to reduce bench space took up by the light and previous fan I had and it was worth it for that.
