: So I just got back from Home Depot where, in preparation for sanding, I
: bought a couple 3M "Woodworking and Sanding Painted Surfaces"
: respirators.

: As I read the fine print now that I'm home it says "Helps keep
: non-harmful sanding dust out of your nose, mouth, and lungs during
: do-it-yourself/homeowner projects."

: Great! It keeps the NON-HARMFUL stuff out, but apparently it just lets all
: the HARMFUL stuff right through!?

: So, is this just a funny mistake on their labeling or did I buy the wrong
: kind of respirator? The one I got is one of those paper ones with some
: sort of filter material sandwiched between the paper and has a nice little
: exhalation valve on the front. It's clearly enough to prevent me from
: inhaling the sawdust - but after reading that I'm wondering if there's
: microscopic bits (you know, the *harmful* bits - lol) in the sawdust that
: will go right through this respirator?

: Thanks...

They will work, no respirator other than a supplied air one, will keep every microscopic bit out of your lungs. Keeping the majority of the dust out is a good thing

Every product has liability statements attached anymore, that's why the warning lable is there.
