Key Features
Overview
This is a disposable vacuum dust bag designed for fine dust collection. The Milwaukee Fleece Dust Bags (3 PK) - 4 Gallon (49-90-1939) are built specifically for the M18 FUEL™ 4 Gallon Wet/Dry Vacuum w/ PACKOUT™ Compatibility & VACLINK™ (0971-20), giving that vacuum a proper fine-dust solution instead of relying on the main filter alone.
The fleece material is rated at 98.5% filter efficiency, which matters most when you're vacuuming drywall dust, sanding debris, or other fine particulate that would otherwise blow straight through a standard bag and load up your filter in a single job. Because the bag is fully enclosed, it works as a pre-filter - it catches the debris before it hits the vacuum's actual filter, which means that filter lasts noticeably longer between cleanings or replacements.
Installation is simple: slide the bag into the dust bag holder near the inlet in the tank, run your job, then pull the bag out and toss it - no dumping a tank full of fine dust into the air on a jobsite. Each pack includes 3 bags, enough to get through a multi-day job without needing to reorder mid-project.
This is the right accessory for anyone running the M18 FUEL™ 4 Gallon Wet/Dry Vacuum on dust-heavy work - drywall finishing, sanding, concrete cutting cleanup - where fine particulate, not just chunks of debris, is the real problem.
Built to Disappear When the Job's Done
A fully enclosed fleece bag means fine dust stays contained from the moment it enters the tank to the moment you pull the bag back out - no shaking a filter out over a trash can.
- 98.5% filter efficiency for fine dust
- Fully enclosed, disposable after use
- Slides into the dust bag holder near the tank inlet

Pro Tip
Swap the bag before it looks full. Once the fleece surface loads up with fine dust, suction drops even though the tank still has room - change bags at roughly two-thirds full to keep pickup consistent.
