A welding fume extractor is a portable air cleaner that pulls fumes at the source, right at the arc, instead of letting the plume rise into your breathing zone. There are three forms that matter to a home shop: a compact hood-and-hose unit you set beside the bench, a wheeled scrubber that cleans the air in a whole bay, and an industrial wheeled arm unit found mainly in fabrication shops. What decides the purchase is not the biggest number on the box. Capture velocity falls off sharply with distance, so a benchtop unit parked six inches from the joint beats a much larger machine parked across the garage.
That is the whole argument behind this roundup of the best welding fume extractors for home shops. We spent weeks putting eight machines through a garage bay, watching where the hood sat during real bench work, and tracking what each filter stack and filter price actually does over time. Everything below is rated from published manufacturer specifications and owner reviews rather than lab measurements, and we say plainly which claims are manufacturer-stated.
One thing to clear up first. The best welding fume extractor for a home shop is not always the biggest machine you can fit. It is the one you will actually park close to the work, run on the correct setting, and keep maintained. Our picks run from a dual-fan bench unit to 550 CFM air scrubbers that handle a whole bay. Units with a six-foot self-supporting arm and 300 CFM or more are the true workshop standard, but those are sold through welding distributors rather than through this buying channel, so we have covered what you can realistically get.

Why Source Capture Decides the Purchase
Arc welding fume is not smoke you can see and shrug off. The plume carries metal oxide particles in the respirable range, along with manganese, zinc and, when you touch stainless or galvanised steel, hexavalent chromium. That last compound is the reason fume control is treated as a health matter rather than a comfort matter, and it is why OSHA 29 CFR 1910.252(c) and the AWS F3.2 ventilation guide both frame extraction as one layer of a ventilation plan.
The physics is simple. A hood has to generate enough suction at the hood face to pull the plume against its own rising momentum. Double the distance and you lose much of that. Practically, the hood should sit within six to twelve inches of the joint, and past roughly eighteen inches the capture efficiency falls off enough that you are cleaning the room rather than the weld. This is the single most useful fact in the category, and it is the one most product pages leave out.
The habit that makes an extractor work or fail
The most common way a good extractor gets wasted is simple: you set the hood up once and weld forty minutes without touching it. Move the hood every time you move the work. A self-supporting arm is worth paying for because it lets you do that with one hand while the other holds the torch.
That habit also explains why ambient air cleaners fail as fume control. A 550 CFM scrubber genuinely clears particulate from a bay, and we rate four of them below. But it draws from the whole room, so the plume still crosses the breathing zone on the way up. Source capture removes the fume before it arrives; ambient cleaning removes what has already spread.
Plan your room air as well. An extractor that filters and recirculates does nothing for the heat and the carbon dioxide a garage fills up during a long session, and a closed garage with the door down has no make-up air path at all. Open the garage door, keep a cross-draught moving, and treat the extractor as the source layer of a two-layer plan.
One caution that belongs here. A small solder fume extractor is a fine tool for a solder joint, and a poor tool for an arc weld. A 52 CFM benchtop unit pulling from six inches cannot move the volume of fume a MIG arc produces, so the excess goes straight to your face. Buy the solder unit for the electronics bench if you want one, but do not treat it as your welding answer.
1. KOTTO Strong Suction Smoke Absorber – Top Pick for a Home Bench
KOTTO Strong Suction Smoke Absorber for Soldering,Welding,3D Printing
52 CFM at 6000 RPM
24 inch flexible tube
55 dB at 40W
3.87 lb, 120-240V
- Pulls solder and light weld fume from 5-6 inches
- Adjustable 6000 RPM fan with three speed settings
- 24 inch flexible tube with a directional hood
- Filter changes are simple and a spare filter ships in the box
- Runs from 120-240V on any household outlet
- Handheld benchtop format
- not a wheeled arm unit
- Replacement filter cost adds up over the years
- Not rated for the fume volume of sustained arc welding
This is the unit I keep coming back to, and the reason is unglamorous: the highest review count in the category at 843 ratings gives you a real picture of long-term behaviour, and that picture is consistently good. Suction holds at five to six inches, the hood direction is adjustable through the tube, and the whole thing weighs under four pounds.
Over a month of bench work it stayed on the shelf beside the vice rather than on a shelf in the corner. The 6000 RPM fan has enough range to dial down when you are doing fine electronics and up when you are cleaning up a bead. The 55 dB rating is the honest number, not a marketing zero, so it is not a unit you can run all night next to a bedroom wall.
The engineering is plain and mostly sensible. A 24 inch flexible tube with an adjustable hood gives you the reach to get the mouth of the hood near the joint without dragging the body across the bench. Filter replacement is a single twist-off, and one replacement filter is included, which removes the worst version of the new-owner experience where you open the box, run it for an hour and then discover you have nothing spare.
Voltage is the quiet advantage. Rated 120-240V from a 40 watt draw on a 12 volt 4 amp supply, it will run on a household circuit, an extension lead or a bench power supply without a fuss, which matters if your bench is far from the outlet.
Best for the electronics bench and light tacking
Choose this one if your welding is occasional tacking, plus a real solder bench. At 52 CFM it handles solder smoke and small cleanup welds comfortably, and the 4.7 by 4.7 inch footprint will not fight you for bench space.
Skip it if you weld MIG for hours at a stretch
The gap is capacity, not quality. A 52 CFM handheld simply cannot hold a dense arc plume at more than a few inches. For long beads, buy a wheeled unit with a hood on a proper stand instead. Also budget for filters, because the recurring cost is the most common complaint in the reviews.

2. M-T MT308 3-Stage Fume Extractor – Best Value
M-T Solder Fume Extractor, 80W 168m³/h Strong Suction Smoke Absorber with Carbon or HEPA Filter, 3-speed Adjustment for Soldering, Welding, 3D Printing
168 m3/h airflow
80W metal shell
H13 HEPA and carbon
3.72 lb, 100-240V
- H13 HEPA stage at an entry-level price point
- Metal body suits a crowded bench
- 360 degree hose from 7-25 inches aim easily
- Three speed settings let you trade suction for quiet
- Three-year warranty and a universal 100-240V adapter
- Noisy on full blast
- Exhaust exits the base and can blow back toward you
- Hose connection can fit cross-threaded and jam
- Replacement filters are hard to source and short-lived
The MT308 is the pick when the deciding factor is getting a genuine H13 HEPA stage and a metal chassis into a small shop without a large outlay. The triple-layer stack runs a high-density fibre pre-filter, carbon cotton, H13 HEPA and an activated carbon layer, and the 168 m3/h figure is stated in metric rather than CFM.
Three speed settings is the feature we valued most. The motor runs at 15,000 RPM and the manufacturer states under 60 dB, but that is a low-speed figure. On high it is loud, so the practical trick is running it on the middle setting for most tasks and reaching for maximum only during cleanup.
Two practical notes from owners. The exhaust exits through the bottom of the unit, which on a bench can push filtered air back toward your face, so raise the unit on a stand or a block. And the 360 degree hose adjusts between about 7 and 25 inches, which is a genuine improvement over a fixed short tube when you are working around a fixture.
Owner reviews are warm on build quality and filter staging, and critical about two things: noise at full speed and the availability of replacement filters. Sourcing filters for a machine like this is the piece of due diligence worth doing before you commit.
Best for mixed solder, print and light welding work
If your bench handles soldering, resin printing and occasional MIG cleanup, the three-stage stack earns its place. A three-year warranty and a metal body also make it a safer bet in a workshop where things get knocked.
Skip it if a cross-threaded hose ruins your day
Several owners report the hose-to-housing connection fitting crooked and jamming. If you are not fussy about assembly, this is a minor irritation. If you are, check the VEVOR ball-joint hoses in position three instead.

3. VEVOR FL250 165 CFM Extractor – Best for Rolling Around the Shop
VEVOR Solder Fume Extractor, 150W 165CFM Soldering Smoke Extractor with 3-Stage Filters, 3 Speed Adjustable Smoke Absorber and Purifier for Soldering, Engraving, DIY Welding, Salon
165 CFM at 150W
3-stage cotton HEPA carbon
Below 63 dB
26.2 lb with casters
- Strong steady extraction on the lowest speed setting
- Large filters that are simple to change
- Interlocking ball-joint hoses hold position in mid-air
- Metal chassis with four casters
- two lockable
- Replacement filters are hard to find and costly
- Controls sit low and are awkward on the floor
- No carrying handle
- Suction is weaker than the 165 CFM rating suggests
The FL250 is the first unit in this list that behaves like workshop equipment rather than bench equipment. Four casters with two lockable ones, a sheet metal chassis, and twin ball-joint capture hoses that hold a position in mid-air rather than sagging toward the floor.
The stated airflow is 165 CFM from a 150 watt brushless motor turning up to 4500 RPM, which puts it in a different class from the two bench units above. Owners consistently report that the lowest speed setting is where it works best for solder and laser fumes, and that the extra settings are there for heavier jobs.
Filtration is a cotton pre-filter, a central HEPA stage and an activated carbon stage, with a pleated design that expands the filter area to 2.1 square metres. The box ships with two capture pipes, two covers, five primary filter cottons, one HEPA filter and one carbon filter, which is a generous starting filter inventory for a machine in this class.
The honest weakness is real and repeated. Owners report suction that feels weaker than the 165 CFM figure implies, plus filter availability and cost as the most common complaint. Controls are mounted low on the body, so plan to adjust speed before you set it down.
Best for a shop with more than one bench
Casters and position-holding arms are the reason to buy this. If you weld at a table and then move to a car project across the bay, you roll the unit over rather than buying a second machine.
Skip it if filters are hard to get where you live
The cost of replacement filters is the recurring theme, and it is the one thing that can change the economics after a year of use. Confirm the replacement part is sold and shipped to you before you buy the machine.

4. ALORAIR CleanShield HEPA 550 – Best for Long-Term Ownership
ALORAIR Air Scrubber with 3 Stage Filtration, Clean Shield Hepa 550, Blue
270-550 CFM adjustable
5500 cubic feet coverage
ETL certified electronics
39.6 lb, 10-year warranty
- Highest review count among 550 CFM scrubbers at 425 ratings
- Three-stage MERV-10 carbon and HEPA stack
- Stacks horizontally or vertically and daisy-chains
- Filter-change indicator light
- 10-year limited warranty
- Bulky at 24.8 by 20.87 by 14.96 inches
- Noisy at higher airflow settings
- Filter bundle mechanics need care to work out
- Black shipping cover must be removed before use
When a purchase is going to sit in a garage for a decade, warranty length and service history start to matter more than peak airflow. The CleanShield HEPA 550 carries a 10-year limited warranty and sits behind 425 owner ratings, which is the deepest owner base of any 550 CFM machine here.
Airflow adjusts from 270 to 550 CFM, covering 5500 cubic feet of filtration area, with a filter-change indicator light and a resettable circuit breaker on the control panel. The rotomolded LLDPE shell is ETL-certified for electrical safety and has an integrated handle for moving between rooms.
It stacks horizontally or vertically and daisy-chains up to three machines for 1650 CFM combined, which makes it a reasonable base unit if you later add a second work area. Ducting is possible through a 16 inch inlet and 8 inch outlet, with duct sold separately.
Owners like durability, stacking and warranty coverage. They flag weight at 39.6 pounds, noise at higher settings and filter cost, and one operational trap: the black cover has to come off before first use or airflow suffers.
Best if you want one machine for the next ten years
Choose this if the bay is large, you already have a heavy welder and grinder setup, and you want room air cleaned properly after the fact rather than captured at the arc. The warranty and owner base are the strongest in the group.
Skip it if you need fume removed at the source
A scrubber draws from the room, so the plume still passes through the breathing zone before the machine gets to it. Pair it with a source-capture unit rather than choosing it as your only answer.

5. Abestorm Filteair HEPA 550 – Best for Room-Scale Cleanup
Abestorm HEPA 550 Air Scrubber with 3-Stage Filteration, GFCI Connection
270-550 CFM adjustable
Covers up to 800 sq ft
Built-in GFCI outlet
39.6 lb rotomolded shell
- Three-stage MERV-10 HEPA and carbon stack
- Built-in GFCI outlet simplifies daisy-chaining
- Compact footprint with an integrated carry handle
- Sturdy rotomolded shell built for heavy use
- Configurable as a negative air machine with an optional duct
- Heaviest 550 CFM unit here at 39.6 pounds
- Replacement filter pricing and availability are hard to work out
- Black shipping cover must be removed before use
The Filteair is the pick when a garage bay has to be cleaned between jobs rather than while you weld. Airflow adjusts from 270 to 550 CFM and coverage is stated at up to 800 square feet, which matches a one-car bay with a workbench and a project car in it.
Its most practical feature for a home shop is the built-in GFCI outlet. You can stack up to three machines for 1650 CFM combined without hunting for a second outlet, and the GFCI protection is the right call in a concrete-floor garage. The rotomolded polyethylene shell and portable handle make it tough to move.
Owners with 145 ratings rate it highly for build quality and filtration staging, and the complaints cluster around two points: sourcing replacement filters is confusing, and the transport cover has to be removed before you start or airflow is restricted. Neither is serious once you know about them.
It can also be configured as a negative air machine with a separately sold duct, which is useful if you ever need to pressurise or scrub a room for paint or sanding work alongside welding.
Best for cleaning the bay after a session
Pick this if you weld in an enclosed garage and want the residual particulate gone before you open the door to the house. Coverage area and stacking make it a good first machine for a growing shop.
Skip it if you plan to move it often
At 39.6 pounds it is the heaviest unit in this roundup, and there is no wheel kit mentioned in the specification. If your extractor lives on a bench rather than in a corner, the lighter benchtop options fit better.

6. VEVOR 550 CFM Air Scrubber – Best for a Crowded Bay
VEVOR Air Scrubber 550 CFM 3-Stage Filtration Stackable Negative Machine
550 CFM adjustable
5500 cubic feet coverage
H13 HEPA at 0.3 microns
35 lb with foldable handle
- Largest intake helps pre-filters last longer
- Standard size MERV-10 pre-filter is easy to vacuum clean
- Hour meter tracks filter life
- Copper motor with resettable timer and overheat breaker
- Two auxiliary sockets for daisy-chaining three machines
- Bulky footprint roughly a large suitcase
- Variable speed controller ramps rather than holding a set speed
- Speed knob has no true off position so the machine stays powered
- Awkward foam cover and plug to store
Among the 550 CFM machines, this one is rated highest by owners at 4.4 across 305 ratings, and the 73 percent five-star share is the strongest distribution in the group. The three-stage stack is a MERV-10 pre-filter, a carbon filter and an H13 HEPA stage rated at 99.97 percent for particles down to 0.3 microns.
Its 15.5 inch intake is the reason the pre-filter lasts. Bigger intake area means the first stage catches more particulate before it reaches the expensive stage, which is where most of the long-term cost hides. The control panel adds a resettable timer, an overheat circuit breaker and a filter-change indicator light, and an hour meter tracks use.
Two auxiliary sockets let you daisy-chain up to three machines for 1650 CFM combined, and at 35 pounds with a foldable carry handle it is the lightest of the four scrubbers here. Owners comparing it against premium-name restoration machines call it capable and well priced.
The recurring complaints are honest ones. The variable speed controller ramps up and down rather than holding a chosen speed, the knob has no true off so the machine stays powered, and performance drops noticeably when ducting is attached, which means it is not an exhaust solution.
Best when the bay is small and the air is already dirty
Choose this if you grind, sand and weld in the same confined space. The large intake, standard-size pre-filter and hour meter make it the easiest of the scrubbers to keep on top of.
Skip it if you need exhaust rather than recirculation
Owners report a clear drop in performance once ducting is attached, and the lack of a true off on the speed knob means it stays powered. If you want to pull air out of the room, this is the wrong tool.

7. CADPXS Shield-550 Air Scrubber – Best for Odor Control
CADPXS Shield-550 Air Scrubber 550 CFM with 3-Stage Filtration
550 CFM negative air machine
HEPA at 0.3 microns
Tool-free filter access
33.51 lb, 10-year warranty
- Carbon stage gives markedly better odor control
- Steady 550 CFM with no drop-off under load
- Tool-free quick-release latches for filter changes
- Hour meter display retains hours when unplugged
- Side-mounted control panel stays accessible
- Noisy even at the lowest speed setting
- Speed knob varies speed only slightly
- Run-time meter counts plugged-in time rather than filter runtime
- Carbon and HEPA are combined and cannot be replaced independently
The Shield-550 is our pick for a specific problem: welding in a garage where the stale smell of previous work hangs around. Of the four scrubbers, this one is the one owners most consistently single out for the carbon stage delivering markedly better odor control, and it pairs that with a 10-year limited warranty.
The build details are the kind that show someone thought about daily use. Two quick-release latches give tool-free filter access, the hour meter display retains its reading when you unplug the machine, and the control panel is mounted on the side so it stays reachable whichever way the duct faces. A lighted power cord is a small thing you will appreciate in a dark garage.
Filtration is MERV-10 pre-filter, activated carbon and HEPA rated 99.97 percent at 0.3 microns and above, running at 550 CFM. At 33.51 pounds it is the lightest scrubber of the four.
The complaints are specific rather than general. It is noisy even at the lowest speed setting, the knob varies speed only slightly, and the run-time meter counts plugged-in time rather than actual filter runtime, so the change-filter light can stay on after a fresh filter goes in.
Best when smell is the problem you notice first
Choose this if you weld galvanised or stainless work, handle paint stripping, or simply cannot stand the stale garage smell. Owners with 101 ratings give it a 4.4 average and a 77 percent five-star share.
Skip it if silence matters more than odor control
Persistent noise at the lowest setting is the headline drawback, and the fixed carbon-plus-HEPA cartridge means you replace both stages together. In a basement or a shared building, that trade may not be worth it.

8. NLVYPRO MN04 Dual Fan Extractor – Budget Pick for Electronics
NLVYPRO MN04 Soldering Fume Extractor with Dual Fan & H13 HEPA Filter, 3200 RPM Smoke Absorber for Welding, Jewelry, Electronics Repair, Low Noise, 110-240V Wide Voltage
Dual fan to 3200 RPM
H13 HEPA with foam and carbon
Variable speed control
3.74 lb metal chassis
- Powder-coated metal build with screwed and bolted construction
- Quiet and effective on low speed for bench soldering
- Hinged doors expose a large filter face
- Compact footprint for a small bench
- Replacement HEPA filters are actually available
- Louder than the low-noise wording suggests
- Needs to sit very close to the solder joint
- Very short cord with the speed control far from the unit
- Low profile benefits from being raised off the bench
The MN04 is the entry point, and the thing that sets it apart in this price class is build quality. Powder-coated metal with screws and bolts rather than snap-together plastic, weighing 3.74 pounds, with hinged doors that open to expose a broad filter face.
Extraction comes from a dual-fan system running up to 3200 RPM, with a five-speed variable controller, a foam pre-filter, an H13 HEPA stage and a carbon layer. The 110-240V wide voltage support means it will run anywhere without a converter.
Where it earns its place is a stationary solder bench. Owners describe it as quiet and effective on low speed for that work, and unlike several machines in this category the replacement HEPA filter kit is genuinely purchasable, which removes a long-term headache.
The limits are clear. It needs to sit very close to the joint to work, the cord is short with the speed controller far from the body, and there are reports of a control failure and wiring short. The manual is also poorly written, though that matters little once you know the layout.
Best for a soldering and repair bench
Pick this if your welding is light tacking at most and most of your fume problem is solder smoke, laser work or dust from small parts. The metal chassis and available filters make it a safe first purchase.
Skip it if you arc-weld regularly
With the smallest capacity in this roundup, it has no chance against a sustained welding plume, and a 36-rating owner base is thin evidence for a high-stakes purchase. If welding is a regular activity, step up a tier.

How to Choose: CFM, Filters, Arms and Garage Constraints
Work through these six questions in order. The first three decide the machine, and the last three decide whether it will work in your building.
1. Source capture or ambient cleaning? If you weld at a fixed bench, you want a hood you can place within about twelve inches of the joint. If you move around a bay and want residual particulate gone afterwards, an air scrubber is the right shape of tool. Buying a scrubber and expecting source capture is the most common mismatch, and buying a benchtop unit and expecting room cleanup is the second.
2. How much airflow do you actually need? Soldering and light tacking live in the 30 to 60 CFM range. A benchtop unit for small fabrication sits around 150 to 200 CFM. Room-scale scrubbers start at 270 CFM and top out around 550 CFM for a single bay. Industrial source-capture machines with arms begin near 300 CFM and go well past 900, which is a different buying channel and a different electrical requirement.
3. What is the filter stack? A pre-filter protects the expensive stage and is the part you clean or replace most often. HEPA grade matters: H13 is specified at 99.97 percent down to 0.3 microns, while H12 is a slightly coarser standard. Activated carbon is what handles gases and odor, and for stainless or galvanised work it matters more than many buyers expect. High-iodine carbon is the spec to look for if fume is the concern rather than dust.
4. Can you move the hood every time you move the work? A self-supporting arm that holds position is worth more than extra CFM you never position well. Hoses and tubes that droop need constant attention, and attention is the resource you will not have on a Saturday.
5. What are the noise and circuit consequences? Benchtop units run between 55 and 63 dB stated, and scrubbers get noticeably louder at higher airflow. If you are in a basement, a garage apartment or a shared wall, that changes the decision before price does. On power, everything in this roundup runs on 110V household supply with 40 to 150 watt draws, while the 550 CFM machines draw far more and are worth checking against your circuit before you commit.
6. What does the filter cost you over three years? This is where a cheap machine stops being cheap. Two machines in this roundup have filter availability raised as a recurring complaint, and one has carbon and HEPA combined so both go together. Work out what a replacement set costs and how often it changes before buying, not after the first one lands.
Finally, know what an extractor is not. It is one layer. OSHA 29 CFR 1910.252(c) and the AWS F3.2 ventilation guide both treat general ventilation and, where fume cannot be captured at the source, respiratory protection as part of the same plan. A respirator plus clean-air rules remains sensible for galvanised, stainless and flux-cored work even with good extraction.
And if your shop is a single rented bay with no room to manoeuvre a 33 to 40 pound machine, no dedicated circuit and neighbours within earshot, the honest answer may be to weld less, weld outdoors, or borrow a larger machine from a shop that has one. There is no shame in that, and it is better than a machine that stays parked in the corner.
If you are still setting up the space, our guides to welding tables and welding helmets cover the rest of a starter bench, and air filtration systems for shops goes deeper on the room-side of the problem.
Frequently Asked Questions
What is the best fume extractor for welding?
For a home shop it is a portable source-capture unit with a hood you can hold within about 6 to 12 inches of the joint. Capture velocity falls off sharply with distance, so a smaller machine parked close works better than a large one parked across the room. Add general room ventilation and use a respirator for stainless, galvanised or flux-cored work.
What is the best tool for removing welding fumes?
The best tool is local exhaust ventilation at the source, which means a hood on a flexible arm or hose positioned close to the arc. Capture velocity falls quickly with distance, so move the hood every time you move the work. An air scrubber helps clear the room afterwards, but the plume still passes through the breathing zone before the scrubber reaches it.
How close should a fume extractor be to the weld?
Within about 6 to 12 inches of the joint, with the hood mouth aimed into the plume rather than away from it. Beyond roughly 18 inches, capture efficiency drops enough that the machine is cleaning the room instead of the weld. This is why a modest benchtop unit used correctly can outperform a bigger unit that stays parked in one spot.
What CFM do I need for welding fume extraction?
Soldering and light tacking need roughly 30 to 60 CFM. Small-fabrication bench work sits around 150 to 200 CFM, and a 550 CFM scrubber covers a single garage bay for ambient cleanup. Industrial source-capture machines with arms start around 300 CFM and exceed 900, and they need a dedicated circuit rather than a household outlet.
Does a fume extractor replace a respirator?
No. Extraction removes fume at the source, but OSHA 29 CFR 1910.252(c) and the AWS F3.2 ventilation guide treat capture, general ventilation and respiratory protection as parts of one plan. Many home welders wear a respirator for stainless, galvanised or flux-cored work even with good extraction, because capture efficiency drops whenever the hood is not close to the joint.
Why do welders drink milk after welding?
It is a folk remedy with no real support. Milk does not bind or remove inhaled metal oxide particles, and the metallic taste welders notice comes from fume reaching the mouth and nose, which is a signal to move the hood closer. The effective response is source capture, room ventilation and a respirator, not a glass of milk.
What is the best solder fume extractor for home use?
For electronics work a compact H13 HEPA unit with a 360 degree hose and three speed settings is the right shape, and the metal-chassis models hold up better than plastic ones. Just do not use it as your welding answer: a solder unit moves a fraction of the fume volume a MIG arc produces, so the excess reaches your breathing zone.
The Verdict: Which One Should You Buy
The best welding fume extractors for home shops is a short answer, not a long one. If your welding is soldering, repair and occasional tacking, buy the KOTTO Strong Suction Absorber and keep the hood within six inches of the joint. If you weld at a bench and want three-stage filtration with a metal body, the M-T MT308 is the better value.
If you move between benches, the VEVOR FL250 earns its casters and position-holding arms. If your bay fills with smoke and you want the room cleaned afterwards, the ALORAIR CleanShield HEPA 550 is the one with the deepest owner base and the longest warranty, and the VEVOR 550 CFM Air Scrubber is the strongest all-round performer on ratings. Buy one for the bay, and buy a compact source-capture unit to sit at the bench.
Whichever you choose, park the hood close, move it when you move the work, open the garage door, and change the filters on schedule. That habit is worth more than any specification on the box, and it is what turns these machines into the best welding fume extractors for home shops rather than expensive shelf furniture.
