Rockler Pre-Filters for F1020PG Air Purifier, 5-Pack
SKU: 55999 ID: 605246973
These pre-filters fit into the top section of the primary carbon filter on your F1020PG Air Purifier (#55155, sold separately). By replacing the pre-filter before it becomes clogged, you greatly increase the lifespan of the larger and more expensive HEPA carbon filter. The more efficiently your air purifier is running, the more efficiently your laser engraver will run as well. Change your pre-filter when the filter monitor on your purifier indicates a clogged filter. Always use new replacement filters from the original manufacturer.
