the N95 doesn't work that well... how i know? i tried spraying
my A10 thunderbolt and the fumes still managed to find it's way
through to my nose... 
i'm also looking for such a mask.
N95 isnt designed to block out fumes. If not, people would have
cut cost and get this instead. 
Hmm why not try those DIY stores? I mean The D.I.Y store. I also
trying out one day.
