Keep your workspace clean and protect your extractor with Milwaukee fleece filter bags. This 5-piece pack of 30L bags is designed specifically for Milwaukee as 30 and as 42 dust extractors, including the as 30 lac and as 30 mac models. Made from tear-resistant fleece, each bag acts as an effective pre-filter that captures fine dust from drywall sanding, woodworking, and concrete drilling. By preventing the main filter from clogging, it helps maintain continuous suction performance throughout the job. When it is time to empty, the integrated sealing tab closes the bag opening securely for dust-free disposal.
