So anything that evolves during the use of Super Glue (or heating of plastisol) that is smaller than 0.3 microns you breath in. Most gases, organic vapors, acid fumes, etc are much smaller than the 0.3 microns, add a few zeros after the decimal small and easily pass through the particulate filter. I got my respirator and replacement cartridges from Home Depot. The reaction also stabilizes the ridge detail to better preserve for possible future enhancement (through use of fingerprint powder .
