h'lo...

my neighbor gave me a 3m 6800 full face respirator the other day, belonged
to her hubby before he died. I don't know much about these things... I'm
wondering if somebody can suggest the proper combination of
cartridges/filters for this thing.

in order of usage

Soldering (stained glass/leaded glass) - mild chemicals, lead
dust/particulate
woodworking - sawdust
wood finishing - varnishes etc

the borg have smaller more specific purpose respirators, for about $50 CDN,
but I'd need 2 different ones to cover all bases.

any thoughts?



Consider 3M's P100 filters that fit this assembly. The P100 filters are petroleum resistant and filter 100% of particles over 0.3 microns. As others have said, I think it's overkill for general woodworking but a good idea for soldering, welding, finishing, etc.
