Disposable respirator or air system?

I've used the 3m disposable respirators and I don't use them very long before I toss them. I have an air system for sandblasting and sanding but I've never used it in the booth because it's one more hose to drag around. I was curious what you guys are using. I sprayed 4coats of Imron on a huge 1920's frame with a disposable that was new and I tossed it. I don't feel that great tonight. I've heard how nasty Imron is but I always wear gloves and shoot suit and I'm careful. I have a 3m full face mask but I was spending more time replacing the clear lense covers than painting on this frame.
I know the eyes absorb a lot of stuff so I'd like to use it but crawling around the bottom of this frame one blast in the face and I couldn't see. Either 30 hour work hours the past two days or paint fumes are getting me.
 
i use a bullard hood. put a t on it and run a 3 ft hose for the gun. the lead hose is on a belt so i only have the one hose to work with.

I do not know what you mean by disposable, i hope you aren't referring to a dust mask. I have watched videos on utube of guys doing just that, shooting clear with a dust mask. I have always wondered if they are still alive.
I had always used a North half face respirator with organic vapor cartridges. I use a new set of cartridges with color or clear. I recently acquired a supplied air system and used it ont he last paint job. I am not use to it and must say I still prefer the face mask at this point, but will continue to use the supplied air and get used to it.
 
just regular filters then the toilet paper filter in the booth. there is a charcoal filter on the hood hose. not something i would use daily but works for what i do.

This is the setup I use as well. With good airflow in the booth I have never even sensed I was breathing in anything bad. The trick is to change those filters regularly.
 
I use 3m disposable paint respirators. The charcoal filters aren't replacable on them, you just chuck the whole thing. My 3m full mask has the replacable cartridges on the mask. I've been using them for 5years, always put back in the sealable bag, and replace frequently. I basically used one respirator to seal and paint this frame and then canned it. I'll use on several times just for spraying parts but I was in the booth a couple hours yesterday. I probably should have cranked the booth up but I get the best finishes with a slower even air. What gets me thinking about this is lately I've been taking allergy drops in my eyes. One drop a day and from that one drop you can taste the medicine within 10 seconds. That tells me the eyes can really absorb that crap.
This frame has really wide running boards and I couldn't reach over and paint the inside rails without fear of sticking my knee into the board paint. This means I had to crawl into the frame sitting between the narrow rails and paint the sides. This leads to paint blasting in the face. This is why I couldn't use full mask as within a 30 seconds I couldn't see anything and I didn't have time to keep replacing the tear off and keep the frame wet. I guess I just need to step up into a new booth that moves serious air. I see most new ones have 30" fans and mine is a 24".
I should setup my supplied air into the booth. It's great because it supercharges the air into your lungs and energy definetly goes up. Works great for hard sanding.
 
I have a separate oiless compressor for my fresh air supply, if you wear a hood it keeps you a bit cooler, but I wear a SAS shield. Feel 10 times better after painting when I use the fresh air supply
