Cartridge Cycle Management

Reusable mask cartridges have hard service-life limits — typically 6 months from first opening regardless of use, sooner if odour breakthrough is detected. ProfTek can establish a cartridge replacement subscription matched to your roster, with cartridge type selected per the SDS of each handled substance. Combined ABEK1P3 cartridges cover the broadest gas range but at higher cost than single-class filters — our team can advise on the cost-effective specification for your application.
