Our Large Wet/Dry Vacuum Foam Wet Filter is optimized for wet pickup applications. It is compatible with multiple Milwaukee wet/dry vacs (0910, 0920, 0930, 0931). The foam material allows water through but deflects and stops debris from getting into the motor, protecting the motor from debris and increasing the tool life. You can quickly swap or clean filters with the easy access quarter-turn design. The MILWAUKEE® Large Wet/Dry Vacuum Foam Wet Filter is dry cleanable, and washable with water when necessary.
