POWERTEC 75006 Inner Filter for POWERTEC AF4000 Air Filtration System

The POWERTEC Inner Filter (for the POWERTEC AF4000, Shop Fox W1830, Rikon 62-4000, etc) allows your dust-collection system to operate at its peak efficiency and effectiveness. This high-performing and ultra-effective outer filter features a high dust-holding capacity, meaning that the dust, dirt and other airborne particles (as small as 1 micron!) are extracted and trapped in your filtration system and not released into the air that you breath. These handy filters are much more effective than fiberglass filters. This premium filter makes certain that your workshop and/or home air-quality is clear, clean and optimally healthy. Hard-working filters, pristine results!
