DeWalt Disposable Fleece Liner

What they are and why I use them

On concrete and masonry jobs, the mess isn’t just annoying—it’s a health and workflow problem. I’ve been pairing the DCV585 extractor with DeWalt’s fleece liners to keep silica-laden dust contained from cut to cleanup. These liners are simple: a disposable fleece bag that lines the extractor tank so I can cap, pull, and toss without a plume of dust coming back at me. They’re sold in a five-pack, they’re white, and they’re designed specifically to fit the DCV585. Nothing flashy, but they change the day-to-day of dust management in a meaningful way.

Setup and fit

Installation is straightforward. The fleece liners are cut to the right shape and port location for the DCV585, and the collar mates cleanly with the inlet. The fit matters—if a bag sags or drifts, you end up with bypass dust in the tank and a mess later. These sit securely, don’t twist off under vibration, and don’t collapse on themselves as suction builds. I can install one in under a minute without fighting the rim, which is more than I can say for many generic bags.

One practical note: these are dry-use liners. If you’re switching to wet cleanup, remove the liner. Fleece and slurry don’t mix, and you risk tearing and clogging.

Performance on fine dust

Where these liners shine is fine dust—grinding, tuckpointing, and concrete surfacing. The fleece media holds dust evenly across the surface rather than caking in one spot. Airflow stays consistent longer than with paper liners I’ve used on other extractors. You can feel it in the hose: the extractor doesn’t sound starved as the bag fills, and the tool remains predictable against the substrate.

Containment during disposal is the headline benefit. With paper or bare-tank setups, emptying can undo a day’s worth of dust control. With these, I cap the collar, fold the liner in on itself, and the dust stays sealed. The inside of the tank remains significantly cleaner, which also cuts down on filter maintenance. I’ve noticed I can go longer between filter pulses or swaps because less dust backwashes into the filter cavity.

Coarse debris and jobsite abuse

For chips, broken masonry, and small aggregate, the fleece handles abrasion better than paper. I’ve stuffed plenty of sharp-edged waste into these without a blowout. That said, they’re still bags—rebar offcuts or long screws can puncture any liner. If I’m doing demolition with mixed debris, I’ll usually run a pre-separator or just skip the liner for that task to save money and prevent accidental tears.

Capacity realities with the DCV585

Let’s talk capacity. The DCV585 isn’t a big extractor, and the liners fill faster than you’d like if you’re doing heavy grinding or prolonged cutting. On a day of tuckpointing, I can go through more than one liner if I don’t use a pre-separator. That’s not a knock on the liner quality—it’s a system reality. If you’re producing large volumes of dust, plan your workflow:

• Use a pre-separator or cyclone to drop out the bulk and reserve the fleece liner for fine dust only.
• Shake the hose and tool shrouds periodically to prevent premature bridging at the liner mouth.
• Don’t pack the liner to absolute full—once you feel suction taper and the extractor changes pitch, swap it. Overfilling increases backpressure and can distort the bag, reducing containment during removal.

Durability and sealing

The fleece material resists tearing when you pull a loaded bag up and out. Seals at the collar stay intact; I haven’t had one pop open during removal. I like to fold and tape the opening for belt-and-suspenders containment if I’m moving bags across a finished space, and the fabric takes tape well. After removal, the tank is usually clean enough that a quick wipe is sufficient—no cloud when you open the lid.

Cost, waste, and value

Disposable liners add recurring cost and generate trash. That’s the trade. In return, you get faster changeouts, better cleanup, less dust exposure, and longer filter life. In my usage, the value pencils out when I’m primarily collecting fine dust. The time saved on filter maintenance and the reduced cleanup at the end of the day matter, and the reduction in airborne dust during disposal is significant.

If your work leans more toward heavy debris or infrequent dust generation, the economics are less compelling. You may be better off reserving these liners for the days you’re grinding or cutting masonry and running bare-tank for rough cleanup.

Compatibility considerations

These are cut for the DCV585. Fit and collar design are not universal across DeWalt extractors, and aftermarket bags rarely align perfectly. If you’re on the DCV585 platform, these are the right liners. If not, check your extractor model carefully—“close enough” doesn’t work well with liners, and misfit bags lead to bypass dust and poor performance.

Practical tips from the field

• Pre-stage a second liner: Keep a fresh one folded in the extractor’s storage so you’re not hunting mid-task.
• Don’t chase the last ounce: Swap early to protect airflow and ease removal.
• Pair with proper shrouds: The liners help at disposal; the shrouds and extractor do the heavy lifting at the source.
• Watch moisture: Avoid damp material; fleece clogs fast with slurry and can tear.
• Extend life with a separator: A small cyclonic separator dramatically stretches how long a liner lasts on grinding jobs.

What could be better

I’d like a higher-capacity option for the DCV585 ecosystem to match these liners. The liners themselves are sturdy and well-fitted, but the extractor’s tank size means frequent swaps on dust-heavy tasks. A compostable or recyclable liner would also be welcome to reduce waste without sacrificing performance, though I realize performance and sustainability often pull in opposite directions here.

Bottom line

These DeWalt fleece liners are a simple, well-executed accessory that improves the entire dust-control workflow with the DCV585. They install cleanly, hold up under abrasive dust, preserve airflow better than paper, and—most importantly—keep dust contained when you empty the extractor. The recurring cost and added waste are real considerations, and on high-volume jobs you’ll want a pre-separator to keep from burning through multiple liners a day. But for focused concrete and masonry work where fine dust is the enemy, the liners make the system faster, cleaner, and easier to live with.

Recommendation: I recommend the fleece liners to anyone running a DCV585 who regularly generates fine mineral dust. They’re reliable, easy to use, and they materially reduce dust exposure during disposal. If your workflow is dominated by coarse debris or infrequent dust collection, use them selectively or pair with a separator to maximize value.
