Need respirator recommendations

azaustin said
I was re-reading your post and I’m not sure what you mean by using “a good black/solvent with purple HEPA filter.” I know what a HEPA filter is. Is purple the color code for them? What are you referring to when you say “a good black/solvent?” Storing the cartridges in a bag is a good tip which I intend to use. Thanks for your help on this.

Sorry I didn't put more details in, but you are correct about the colors. Black is for organic solvents, purple is for filtering out fine particles. Also cartridges can last up to 8 hours in a single use. Notice I said CAN. Heavy concentrations of fumes will shorten that time.
