This set of 5 replacement filtration cores are designed for use with the XL-300 Laser Filtration Unit. The replacement set consists of 1 Cotton filter core, 1 Glass Filter Core, and 3 Activated Carbon Filter Cores.
The XL-300 filter cores should be replaced on average after 60-80 hours of use, however, this is just a guideline. The lifespan of the filter cores will vary greatly depending on what material is being cut/engraved. We recommend checking the filters on a bi-weekly basis to monitor debris build-up.
