Family ID: 840-0251
Dobu Life Tech 1 78 Pre-Filter is a replacement pre-filter component designed to extend the service life of compatible respirator systems, sourced direct from Korea. Pre-filters are used as a first-stage barrier in respiratory protection, capturing larger airborne particles such as dust and debris before they reach the main filter cartridge, making them a practical consumable for workers in construction, manufacturing, and other particulate-heavy environments.
