Compliment your cleaning collection with the RYOBI Large Wet/Dry Foam Filters (2-Pack). These filters protect your wet/dry vacuum during water clean-ups. Install by removing the cartridge filter and placing the foam filter over the filter cage. For dry debris pick up, we recommend using the RYOBI Large Standard Filter (A32RF06) or RYOBI Large HEPA Filter (A32RF07). Replace your filters every 3 months for optimal vacuum performance. For best results, always pair your RYOBI tools with RYOBI accessories. These Large Wet/Dry Foam Filters are compatible with the RYOBI 40V 10 Gallon Wet/Dry Vacuum (RY40WD01), 18V ONE+ 6 Gallon Wet/Dry Vacuum (PCL735) and 18V ONE+ 4.75 Gallon Wet/Dry Vacuum (PWV200).
