Our large wet or dry vacuum high-efficiency filter is compatible with multiple Milwaukee wet or dry vacuums (0910, 0920, 0930, 0931). An installed high-efficiency filter captures 99% of all particles greater than 0.5 um for fine dust collection, ensuring dust and micro particle collection of debris such as sawdust, drywall dust and wood or metal shavings. You can quickly swap or clean filters with the easy access quarter-turn design. The MILWAUKEE® large wet or dry vacuum high-efficiency filter is dry cleanable and washable with water when necessary.
