Actually, the most bare-bones cheapest solution would be to solder outside with a slight breeze. Only works in certain climates and times of year, tho...

Ah, nice - I do have a half-mask for stuff like spray-painting and worrying about the fit on my cheap laser cutter's exhaust, but wasn't sure how effective it might be.
You learn something new every day, thanks!
Importantly, fumes do not contain lead. Lead oxide fumes only start occuring above 450°C, well above normal soldering temperatures (320-370°C).
The P100 filter catches airborne particles larger than 0.3 microns. Solder fumes are partly particles down to 0.1 microns, but also gases produced from vaporization of rosin; e.g. toluene, formaldehyde, styrene. Those are molecules a lot smaller than 0.3 microns. So the answer is no, just a P100 filter does not solve everything.
If you need to use a mask, I would suggest a 3M 7500 half-mask with the organic vapor/acid gas/P100 combo filter. I use one for glue work etc. and it's got a very tight seal and is pretty comfy (relatively speaking). Will cost you about $40-$50. Does require a relatively clean shave and proper fitting (sniff test) to be effective.
Or you could get a benchtop soldering fume extractor with an activated carbon and HEPA filter, which is a lot more comfortable. Also more expensive though.
