Airboss PT100 40mm Gas Mask Filters

NEW gas mask filters.  Like actually new.  Like in the sealed bag, fresh out of carton new.

PT100 filters are not NBC rated but they do filter out macro contaminants in the air.  Use these with any 40mm compatible half or full face mask.  Useful when you're training in force on force and need a less expensive filter to respire through.  Also helpful when working with a sander and kicking up wood or ceramic dust.  

Keep in mind, filters are highly disposable.  For general use, they are often changed every 30 days to 6 months. If used against oil aerosols, replace them within 30 days or 40 hours of use, whichever comes first.
