90304 Replacement Filter Kit for Shop Vac 90350 90585 90333 90304

About this item

• 【Compatibility】This 2‑set kit includes 2 cartridge filters (90304), 4 activated carbon foam filters (90585), and 2 lids. Perfectly compatible with Shop‑Vac models using 90304, 90333, 90350, 90585 cartridge filters – fits most 5‑gallon and above wet/dry vacuum cleaners . Note: Please check your accessories model and size before purchasing
• 【Use Cartridge or Foam Alone – Important】DO NOT use the cartridge filter and foam sleeve together. The 90304 cartridge filter is designed for dry floor pickup (dust, debris, sawdust), while the 90585 foam filter is for wet floor pickup (water, spills). Never install the foam sleeve over the cartridge filter – doing so may damage both. Use separately for optimal performance
• 【High‑Efficiency Filtration】The 90304 cartridge filter captures 99.97% of airborne particles as small as 0.3 microns – including pet dander, lint and fine dust. The foam sleeve pre‑filter traps larger debris and helps maintain suction power. Both work together (when used separately) to keep your workshop or home air cleaner
• 【Washable & Reusable Design】Crafted with high‑quality rubber and reinforced metal mesh, these filters are fully washable and reusable. When suction weakens, simply rinse the filter or foam sleeve, let it dry completely, and reinstall. No tools required for replacement – swap out old filters in seconds
• 【Long‑Lasting Value Pack】This 2‑set bundle (2 cartridge + 4 foam + 2 lids) provides a year‑round supply for most users. Replace the cartridge filter every 3‑6 months (depending on usage) or clean it regularly for extended life. Much more affordable than buying separate pieces – keep your vacuum running at peak performance without breaking the bank
