Part of Workshop Ventilation How It Works: Capture at the Source
Ventilation equipment compared for first-time workshop buyers
Ventilation equipment compared for first-time buyers: comparing shop vacuums, dust collectors, cyclones, air cleaners and respirators, what each one.
What to take away
- Buy for the port you need to serve. A small high-suction machine and a large high-volume one solve opposite problems.
- Filtration rating matters more than motor size. A powerful collector with a coarse bag returns the finest dust straight to the room.
- Marketing figures are measured at the machine, not at the end of your hose. Expect less at the tool.
- Match the hose to the tool. A 27 mm extractor hose will not fit a 4-inch planer port without an adapter.
- Use published exposure limits or none at all. An invented number is worse than no number.
Ventilation equipment compared for first-time workshop buyers comes down to one question: which port are you serving? The machines look alike, sit in the same aisle and get described with overlapping words. Working out what each one does prevents most bad purchases, and usually shortens the list instead of lengthening it.
Specific extractors, collectors, separators, air cleaners, fans and respirators follow, compared on port size, filtration rating and where the airflow is measured.
The categories, honestly described
The table below keeps the jobs straight. The one after it names real machines and real prices.
Best for
- Shop vacuum
- Small ports, sanders, track saws, cleanup
- Single-stage dust collector
- Large ports on stationary machines
- Cyclone separator
- Dropping bulk material before the filter
- Ambient air cleaner
- Fine dust already suspended in the room
- Exhaust fan to outside
- Solvent vapor, general air change
- Respirator
- The gap the controls leave
- Powered respirator (PAPR)
- Long sessions, beards, hot shops
Wrong choice when
- Shop vacuum
- Connected to a planer or table saw
- Single-stage dust collector
- Used as a room air cleaner
- Cyclone separator
- Expected to filter on its own
- Ambient air cleaner
- Used instead of capture at the tool
- Exhaust fan to outside
- Handling heavy dust loads
- Respirator
- Treated as the primary control
- Powered respirator (PAPR)
- Used instead of capture at the tool
Most home shops need a vacuum and one collector, then an air cleaner much later. Buying the air cleaner first is a common and expensive inversion. Before you spend on ducting, plan how you will document the runs, since photographing a workshop ventilation build is easiest while everything is still open.

Prices are typical US retail as of 2026.
| Named machine | Type | Port or hose | Filtration as sold | Typical price |
|---|---|---|---|---|
| Festool CT 15 E | HEPA extractor | 27 mm hose | HEPA, 99.97% at 0.3 micron | about $550 |
| Bosch VAC090A | HEPA extractor | 35 mm hose, 9 gal tank | HEPA | $600 to $700 |
| Harbor Freight Central Machinery 2 HP | Single-stage collector | 4 in port, 70 gal bag | 5 micron bag | under $300 |
| Jet DC-1100VX-CK | Single-stage collector | 4 in port | 1 micron canister | $700 to $900 |
| Grizzly G0548ZP | Single-stage collector | 4 in port | canister filter | $700 to $900 |
| Oneida Dust Deputy | Cyclone separator | 2 in inlet and outlet | none, separator only | $60 to $200 |
| Oneida Super Dust Deputy | Cyclone separator | 4 in and 5 in | none, separator only | $250 to $350 |
| JET AFS-1000B | Ambient air cleaner | ceiling unit | 5 and 1 micron | $400 to $500 |
| WEN 3410 | Ambient air cleaner | ceiling unit | 5 micron outer | $130 to $180 |
| 3M 6000 series with 2091 cartridges | Half-mask respirator | P100 cartridges | 99.97% | $40 to $70 |
| 3M Versaflo TR-300 | Powered respirator | belt unit and hood | HE filter | $800 to $1,300 |
Festool lists the CT 15 E at 137 CFM through a 27 mm hose, which suits a random orbit sander or a track saw. Jet rates the DC-1100VX-CK at over 1,000 CFM, but that air only moves through 4-inch duct, which no handheld tool has.
Filtration separates the cheaper machines. A 5-micron bag passes the fraction that settles deepest in the lungs, and that is what the Harbor Freight 2 HP unit ships with. The Jet unit ships with a 1-micron canister.
Separators carry no filter. The Oneida Dust Deputy drops chips from one small tool into a bucket, while the Super Dust Deputy takes 4-inch and 5-inch duct ahead of a collector.
How to read the claims
Airflow ratings are usually quoted at the machine inlet with nothing attached. Add a hose, a bend, a blast gate and a machine port, and the figure at the tool is lower. A 4-inch duct is commonly cited as topping out near 350 to 400 CFM, whatever the collector claims.
Compare products on the same basis, and treat any number without a stated test condition as marketing. Jet's 1,000-plus CFM figure comes from an open inlet, not the end of a hose.
Reading Airflow and Filtration Claims
- Airflow quoted at machine inlet, nothing attached
- Add hose, bend, blast gate, machine port
- Compare products on same basis
- Treat number without test condition as marketing
- Ask filter particle size and efficiency
- Check if rating applies to filter or assembled machine
Filtration claims deserve the same skepticism. Ask what size particle the filter captures and at what efficiency, and whether the rating covers the filter alone or the assembled machine with its seals.
Wynn Environmental sells retrofit canister filters for common import collectors, typically $150 to $250, and that change does more for air quality than a bigger motor.
HEPA is a defined rating: 99.97% of particles at 0.3 micron. P100 respirator cartridges carry the same number. A page that says HEPA-style or HEPA-type is selling neither.
What the standards actually cover
To learn which rules govern wood dust, not what a manufacturer says, OSHA's wood dust standards page lists the applicable requirements: ventilation, respiratory protection and hazard communication.
OSHA's table lists wood dust at 15 mg/m3 for total dust over an 8-hour shift, with 5 mg/m3 for the respirable fraction. Western red cedar carries a lower limit of 2.5 mg/m3.
Those obligations fall on employers, not on someone in their own garage. The page is still the quickest way to see the shape of the problem.
Exposure limits are not a target
You will find published exposure limits quoted in equipment marketing. Read them carefully before relying on them. OSHA publishes annotated tables of permissible exposure limits alongside other recommended limits, and notes that many of its own limits are outdated and may not be protective. That is an unusual admission from a regulator and a useful one.
NIOSH recommends 1 mg/m3 for wood dust, far below OSHA's 15 mg/m3.
The practical consequence for a home shop is simple. Do not aim at a number. Aim at capturing dust at the source, keeping the room clean, and wearing protection when neither is complete.
A buying order that works
- A shop vacuum with a fine filter and a hose that fits your sanders. The Festool CT 15 E and Bosch VAC090A both ship with HEPA filters; typically $500 to $700.
- A collector sized for the largest port on the machine you use most. The Jet DC-1100VX-CK and Grizzly G0548ZP use 4-inch ports; typically $700 to $900.
- A separator ahead of the filter, which extends filter life dramatically. The Oneida Dust Deputy suits one small tool; the Super Dust Deputy takes 4-inch and 5-inch duct.
- A fitted respirator you find comfortable enough to wear. A 3M 6000 series half mask with 2091 P100 cartridges runs $40 to $70; a 3M Versaflo TR-300 runs $800 to $1,300.
- An air cleaner, last, once capture is working. The JET AFS-1000B and WEN 3410 hang from the ceiling; typically $130 to $500.
