CNC Dust Collection: How to Choose + 3 Compared (2026)
Shoes, hoses and extraction. A health control, not an accessory.
How to choose
Dust collection on a CNC is a health control, not a housekeeping convenience, and the distinction changes what you buy. MDF dust carries formaldehyde-based binder; FR4 and carbon fibre are respiratory hazards outright; even hardwood dust is a known irritant. Capture happens at the cutter or it does not happen at all - a shop vac in the corner is doing almost nothing.
Start with the dust shoe, because it is the part that decides capture. Shoe diameter must match your spindle or router body - 52mm, 65mm and 69mm are the common sizes on desktop machines and none are interchangeable. Then size the hose to the shoe, and only then worry about the extractor itself.
Matching them to your machine
Measure the spindle body, not the collet nut, when choosing a shoe. A 65mm shoe on a 52mm spindle will not seal, and a shoe that does not seal loses most of its capture. Some shoes ship with adapters for two sizes; check before assuming.
Hose diameter is a trade-off rather than a bigger-is-better choice. A wider hose moves more air at lower velocity, which is right for a large extractor; a narrower one keeps velocity up, which matters on a shop vac. Keep the run as short and as straight as the bench allows, because every bend costs airflow and airflow is the entire mechanism.
Every product below lists the machines it fits; machine pages list the consumables matched to their collet. Browse the machine database to check yours.
How many you actually need
One shoe per spindle diameter you actually run, and a spare hose length. Clear hose is worth the small premium because you can see a blockage forming rather than discovering it as a loss of suction.
The brush skirt on a dust shoe is a wear item - it goes stiff and stops sealing against the work. When capture quality drops noticeably, check the brush before assuming the extractor has weakened.

Dust Collection - common questions
- Do I need dust collection for a CNC router?
- Yes, and it is a health control rather than a tidiness measure. MDF and composite dust in particular are respiratory hazards, and cutting them without extraction at the cutter puts fine particulate into the air you are breathing for hours afterwards.
- What size dust shoe do I need?
- It must match your spindle or router body diameter - 52mm, 65mm and 69mm are the common desktop sizes. Measure the spindle body itself, not the collet nut, and check whether the shoe ships with adapters before assuming it will fit.
- Can I use a shop vac for CNC dust collection?
- Yes, for a desktop machine, provided the capture happens at the cutter through a properly sealed dust shoe. A shop vac has high velocity and low volume, which suits a narrow hose and a small shoe - what it cannot do is collect from across the room.
