Need respirator recommendations

I ended up buying a Honeywell 86610 with a north full face mask with good intentions. I also picked up a nose cup that accepts the air feed hoses that fit nicely under my welding helmet. To be honest, the thought of the chemicals scared the hell out of me so I figured fresh air was best as I couldn't get a straight answer on the filters.....or how log they lasted for that matter. LOL....I sprayed one cup of urethane paint with my new hvlp gun and I never touched it again. I'll pay, and leave the spraying to the pro's with the right equipment.
