After years of breathing dust, mold, plenty of VOC's I finally sprung for the filter system.
These work nicely keeping your carbon cartridges from fouling up too quickly. I used to have a mask that had both these filters, carbon filters, and the "low voc" purple disk filters all on one system, I do miss that setup, like a triple redundancy.
Make sure you have the right filter system for your job, lungs are pretty important, especially later on down the line.
