Not quite...
A (in the US) NIOSH approved organic vapor mask (purple filters) will do the trick. Supplied air is better as you don't have to worry about lack of O2 or excess in other gasses.

Less than $20 US.
No offense, but to be honest if you're allowed to sell a substance like Simple Green as a household cleaning fluid (as it's marketed in the commercial I saw) with little to no warning text, I am sorry to say that NIOSH approved means very little to me. They apparently let a hazardous substance pass, so their masks may just as well be sub-par.
