Right tool for the job

Dust collector or shop vac for a small shop?

Which kind of dust pickup fits which tools in a small shop, and why.

Safety first: read the safety notes before you use any of these.

Short answer

For sanders, routers, track saws and a hobby CNC's dust shoe, a vacuum fits better; once stationary machines join the shop, look at a dust collector too. A shop vac pulls hard but moves less air, while a dust collector moves much more air with less suction (WEN; Fine Woodworking). For fine dust, Fine Woodworking tested HEPA-rated vacs with tool-triggered outlets, and EPA notes that a shop vac fitted with a HEPA filter isn't necessarily sealed so all the air passes through it.

Suction versus airflow

A vacuum and a dust collector both move air, but differently. A shop vac or extractor pulls hard through a small hose, which suits a sander or a router’s port; a dust collector moves much more air at lower pressure, which suits stationary machines (WEN; Fine Woodworking).

Match it to your tools

Make a list of the tools you run most. Portable sanders, routers, track and miter saws and a hobby CNC’s dust shoe point to a vacuum; stationary machines point toward a collector. For planers and jointers our sources disagree: Fine Woodworking says shop vacs don’t move enough air for them, while WEN says a vac may handle their larger chips better.

Filters and fine dust

We don’t rate filters. Look for the maker’s stated rating (Fine Woodworking’s filter review explains bags versus cartridges), and note EPA’s point that a HEPA filter only works as rated if the machine is built so all the air passes through it (EPA). OSHA notes that sanders and routers are hard to control even with exhaust, so dust pickup doesn’t replace a respirator (OSHA).

Your options

Shop vac (wet/dry vacuum)

A tub vacuum with strong suction through a hose about 2-1/2 in. across, a simple filter and usually the ability to pick up water (SlashGear; WEN).

Good for: Cleanup, wet messes, and small portable tools hooked to the hose with an adapter.

  • Fine Woodworking says shop vacs don't move enough air for big chip makers like table saws, jointers and planers.
  • SlashGear's author found plenty of dust still escaped when he ran one on a table saw, and its filter clogged with fine dust, cutting suction.
  • Most tool dust ports are 1 to 1-1/2 in., so you may need adapters for the wider hose (SlashGear).
  • EPA says a shop vac retrofitted with a HEPA filter isn't necessarily sealed so all the air goes through the filter.

Budget: We don't quote a price: sizes and filters vary widely.

HEPA dust extractor (tool-triggered vacuum)

A vacuum built around a HEPA-rated filter, usually with a narrower hose, a disposable or reusable filter bag and an outlet that switches it on with the tool (Fine Woodworking; SlashGear).

Good for: Sanders, routers, track and miter saws, and a hobby CNC's dust shoe.

  • In Fine Woodworking's 2021 test of seven HEPA-rated vacs, every one left almost no dust on a plywood panel after four minutes of 80-grit random-orbit sanding. The test measured dust on the panel, not in the air.
  • The same test found fleece filter bags kept suction steady, but bags held much less than the stated tank size on most models.
  • SlashGear notes extractors cost much more than shop vacs; Fine Woodworking's 2025 review found one tool-triggered HEPA vac at about half the price of the high-end vacs its reviewer owns.

Budget: We don't quote a price: it depends on size and brand.

Dust collector (single-stage or cyclone)

A machine that moves much more air than a vacuum at lower pressure, into a bag, bin or cyclone, either rolled from tool to tool or fed through 4 to 6 in. ducts (WEN).

Good for: Stationary machines like table saws and band saws, and lots of fine sawdust (WEN).

  • Sources differ on planers and jointers: Fine Woodworking says shop vacs don't move enough air for them, while WEN, which sells both, says a vac may do better than a collector with their larger chips.
  • WEN notes some 120-volt collectors need a 20- or 25-amp circuit and some need 240 volts.
  • OSHA's woodworking pages call for duct air speeds of at least 2,500 to 4,000 ft. per minute and regular cleaning and inspection of ducts and collectors.
  • Filters differ: Fine Woodworking's 2006 filter review said old woven bags handle chips but can't be relied on to control the finest dust, while felted bags and pleated cartridges filter it, with cartridges easier to clean. Check the maker's stated rating and compare like with like; EPA explains HEPA means at least 99.97% capture of 0.3-micron particles. We don't rate filters ourselves.

Budget: We don't quote a price: it depends on motor size and filter.

What we'd start with

A shop vac with the right adapters, for cleanup and small tools. Most first shops start with portable tools, and Fine Woodworking says every woodworker ends up needing a shop vac for portable tools and cleanup.

See Shop vac (wet/dry vacuum)

A HEPA dust extractor with a tool-triggered outlet for sanders, routers and a CNC. In Fine Woodworking's 2021 test, every HEPA-rated vac it tried left almost no dust on the panel under a random-orbit sander (it didn't measure the air), and the outlet switches it on with the tool.

See HEPA dust extractor (tool-triggered vacuum)

Add a dust collector once you run a table saw, planer or jointer. Fine Woodworking says shop vacs don't move enough air for those machines, and WEN says collectors move much more air than vacs. Check the circuit it needs first (WEN).

How we picked

We didn't hands-on test these. We read independent tests and guides (Fine Woodworking and SlashGear), a maker's explainer (WEN) and safety pages from OSHA, EPA, CCOHS and the International Agency for Research on Cancer. Every claim on this page comes from a source linked under Sources. Filtration and health statements come only from those safety pages, Fine Woodworking's tests or a maker's own rating, never from us. Safety pages are listed as safety authorities, and WEN's explainer as a maker guide; neither counts toward our source rule. We only name a product when it has at least three independent sources from at least two different outlets, each naming that exact product, including at least one independent test or review, plus the maker's spec page. This guide compares kinds, not products. Some outlets we cite get review samples from tool makers; we don't use pieces a maker paid for or sponsored. Links were last checked on .

No paid links. Every link on this page is a plain link: no affiliate codes or tracking, and no company paid or asked to be listed (disclosure). Links open in a new tab.
