For my current job, I have Plenty of fresh air pumping in and out of the garage. Also, I figured two is better than one and hve attached two filter cartridges on each side of the mask. I screwed in one, then taped(well) the second on top of the first. Worked excellent and not one hint of fumes or anything. In between coats, I exit the work space and wait outside.
