More like this one:

Note the additional filters on the outside which will pick up fine
mists, although like I said, I prefer the true HEPA add-ons for
completeness since they will grab dusts as well as mists.  You can
find out exactly what it will and won't filter by going to 3M's web
site.  They rate the HEPA filters as being appropriate for hazardous
industrial dusts and radio-nucleotides :-)  You're probably fine with
the one I linked to although of course I assume no liability for
anything you may choose to inhale!  3M's site will also give you the
working lifetime of the cartridges.
