Extraction
Wood dust is classified as a Group 1 carcinogen by the IARC, and the harmful fraction is the part you cannot see. This is the guide on this site we would most like you to read.
At the port, extraction sized to the machine — high volume for a 100 mm port, high pressure for a narrow hose. On your face, FFP3 rather than FFP2: 99% against 94%, for a couple of euros. In the air, an ambient filter for what escapes the first two, because the fine fraction stays airborne for hours after you stop.
A cyclone separator at €30. It drops the bulk into a bin before it reaches the extractor, so the filter stays clean and the suction stays up — and it pays for itself in filter bags within months.
Flow falls sharply as diameter drops. Reducing a 100 mm (3.94 in) port to a 50 mm (1.97 in) hose can leave a chip collector performing worse than a vacuum. Match the hose to the port, keep the run short and straight.
Large volume, coarse material. Air volume matters and suction does not, which is why a vacuum chokes on it.
Small volume, fine particles, small ports. Here suction matters and volume does not.
What a workshop vacuum does well and a chip extractor does badly, because the hose is too large.
An air filter deals with what escapes capture. It is a complement to extraction, never a replacement for it.
| The machine | What it needs | What fails |
|---|---|---|
| Planer or thicknesser | High air volume | A vacuum, which clogs |
| Random orbit sander | Suction at a small port | A chip extractor, which does nothing |
| Table saw | Volume, above and below | Below-table capture only |
| Air in the room | A filter unit | Relying on it instead of capture |
Extraction performance falls as filters load, and it falls quietly. A bag or cartridge that looks fine can be passing far less air than it did, and the first sign is usually chips left behind at the machine.
Wood dust is a health hazard, and fine dust is also a fire and explosion consideration in quantity.

Dust class M · automatic filter cleaning
The M-class machine on this page — ten times less fine dust returned to the room, which for hardwood is the whole argument.
Best for: Hardwood work in an enclosed workshop, where the fine fraction is the point
Chip collector · wheeled · 4 adaptors
A proper chip collector on wheels, with four machine adaptors in the box — the right machine for a planer or a table saw port.
Best for: A planer, a table saw or a band saw with a 100 mm (3.94 in) port
≈ $380
1,200 W · dust class L · semi-automatic filter clean
The professional L-class vacuum with semi-automatic filter cleaning — the feature that stops suction fading halfway through a job.
Best for: Site and workshop extraction where suction has to stay constant all day
Two, usually. A chip collector for 100 mm (3.94 in) ports on planers and saws; a workshop vacuum for 32–35 mm (1.26 to 1.38 in) hoses on sanders and routers. Each collects almost nothing in the other's role.
M lets through a tenth of the fine fraction that L does. For hardwood in an enclosed workshop, M — and the price difference is smaller than most people expect.
A vacuum for sanders and routers, where you need suction through a small port. A chip extractor for saws and planers, where you need volume of air.
No. The chips you can see are the harmless fraction; the fine dust that stays airborne is what matters for health, and it is the part filtration addresses.
No. It cleans what has already escaped into the room. Capture at the machine is what stops the dust reaching your breathing zone.
Almost always a loaded filter or a partly blocked hose. Both reduce airflow gradually enough to go unnoticed.
In a small shop, one good chip extractor plus a vacuum is the usual answer. Trying to do sanders on a chip extractor rarely works well.
Yes for sanding and machining. Extraction reduces exposure considerably; it does not eliminate it.
For cutting: Hardwood work in an enclosed workshop, where the fine fraction is the point
Where it shines: Class M — the class to look for if you cut hardwood indoors
Where it disappoints: No current price on amazon.com
For cutting: A planer, a table saw or a band saw with a 100 mm (3.94 in) port
Where it shines: A genuine chip collector rather than a vacuum sold as one
Where it disappoints: The listing publishes no airflow figure and no filter class
For cutting: Site and workshop extraction where suction has to stay constant all day
Where it shines: Semi-automatic filter cleaning, which keeps airflow up through a long job
Where it disappoints: Class L, not M — see below if you cut hardwood

Blades, inserts and spares from the same aisle, at the price we recorded. Check they fit the saw you pick before ordering: it depends on the bore and the part number, which the listing states.

The saws above are drawn from the catalog of this site. Specifications are the published ones, from the maker and from the Amazon product page; prices are the Keepa figure for the date below, and both shift. Ranking uses declared specifications, the balance of stated strengths and stated limits, and price. No machine here has cut wood for us, and the page claims nothing else.

Table saws and planers swing by a hundred dollars or more across the year, and the biggest "discounts" often land at prices the same model sold for six weeks earlier. UniverTrack tracks the real price history across retailers, spots fake reductions, and alerts you when it is genuinely the moment to buy.
