💡 What maintenance routine keeps a shop vac cartridge filter performing best over time?
You rinse the mesh screen weekly to prevent fine particulate buildup from choking the motor stream.

- Scrub trapped grime with mild soap and a soft brush for a handy deep refresh
- Install a fresh unit immediately when airflow drops to protect the internal pump assembly
