Great performance in filtration of particulates and odors associated with welding, grinding. . .
These filters perform flawlessly in respect to their ability to filter out harmful particles and odors associated with welding, cutting, and grinding on steel. My main issues with these filters are due to their seemingly short filter life and their price tag (just my opinion).
ProsExcellent at filtration, fit very snugly into the mask, and have a sturdy build.
ConsTo me they seemed to need replaced fairly quickly, and they are kind of costly.
