HEPA is for removing particles. Soldering results in vaporized flux.
Thus, a HEPA filter would be ineffective, other than the moving the
concentrated fumes away from your face.
Here's a detailed article with a detailed breakdown of solder fumes,
saying "particle inhalation is the main cause of these fume-related
ailments".

Here's a page that claims "Bench-mounted boxes are useless unless fitted
with a HEPA filter". (I do not agree they're "useless")

Here's another, admittedly biased from a filter manufacturer, claiming
"smoke and fume contains particles .... pose the most serious health
risk as they are considered respirable and can easily embed on the
operator's lungs".

Still, I believe the cheap carbon-only products or similar home-made are
a tremendous improvement over nothing at all, mainly because the pull
the fumes away from where you're breathing.
