North 7580P100 Particulate Filter

The North 7580P100 is a low profile, lightweight P100 particulate filter. It is rated at 99.97% efficiency for dusts, fumes and mists. Such filters are often used for lead, asbestos, or welding applications (as long as your contaminants are within the allowable range). It fits all North cartridge respirators like the 7700, 5400, and 7600 series respirators. They are sold by the pair and come 72 pair per case. Case purchases are not necessary. They do fit under many welding helmets when worn with a half mask respirator.
