This set of 5 replacement filtration cores is designed for use with the XL-300 Laser Filtration Unit. The replacement set consists of a cotton core, a glass filter core, and three activated carbon filter core layers.
The XL-300 filter cores should be replaced after approximately 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.
