Replacement pre-filters and coarse filter media for industrial fume extractors and dust collectors. Pre-filters are the first stage of filtration — they capture large particles, weld spatter, and coarse dust before they reach your expensive HEPA or main cartridge filters. Replacing pre-filters regularly extends main filter life significantly, reducing your total cost of filtration. Compatible with major extractor brands.
