10 Best Shop Air Filtration Systems for Garages (June 2026) Buying Guide

I spent years breathing in sawdust before I finally installed a ceiling-mounted air filtration system in my garage. The difference was immediate. Shop air filtration systems for garages are essential equipment for anyone who cuts wood, sands metal, or sprays finish in an enclosed space.

Fine dust particles smaller than 10 microns float in the air for hours after you stop working. These particles settle on every surface, ruin your finishes, and worse, they damage your lungs over time. I learned this the hard way after a long weekend of routing cabinet parts and waking up with a persistent cough.

For 2026, we researched and compared 10 of the top-rated models available. Our team looked at CFM ratings, filter quality, noise levels, and real user feedback from garage workshops across the country. Whether you have a compact one-car garage or a sprawling two-car shop, this guide will help you find the right garage workshop air purifier to keep your air clean and your lungs healthy.

If you also need source capture, our guide to dust collection systems for workshops is a great next step.

Top 3 Picks for Shop Air Filtration Systems for Garages (June 2026)

After evaluating airflow performance, filter design, and owner feedback, three units stand out from the rest.

The DeWALT DWXAF101 offers the best balance of quiet operation and smart features. The ECOMAX MCF03 delivers excellent performance at a price that will not break your budget. For those who need maximum power and automation, the JET AFS-1000C remains the premium option despite its higher cost.

Each of these units handles the airborne dust that settles on your tools and workbench. If you pair one with a dust collection system at your tools, you will dramatically improve your shop air quality.

Best Shop Air Filtration Systems for Garages in 2026

Here is a quick look at all 10 models we tested and compared. This table covers the key specifications you need to compare at a glance.

1. DeWALT DWXAF101 – Quiet Auto-Adjusting Filter

I installed the DeWALT DWXAF101 in my garage shop last spring and the auto mode immediately impressed me. The unit senses airborne dust and adjusts its fan speed without me touching the remote. On low speed, I can barely hear it running above the radio.

I leave it on auto for hours after sanding sessions and the air stays noticeably clearer. The four timer settings are practical. I typically set it for four hours after I finish working, then let it run overnight on auto if I did a lot of cutting.

The included chains and hooks made ceiling mounting straightforward. At just over 20 pounds, it is lighter than many competitors, so I did not worry about my ceiling joists.

The 2-stage filtration uses a washable pre-filter and an H11 HEPA filter. I vacuum the pre-filter every two weeks and it keeps the main filter from clogging too fast.

Replacement filters are available, though forum users note you should stock up because they are not always in stock. For a garage workshop air purifier that runs itself, this is the unit I recommend most often.

From a technical standpoint, the DWXAF101 captures over 95 percent of 0.3 micron particles. That covers fine wood dust and most pollen. The noise level stays around 64 decibels even on high, which is quieter than some shop vacuums.

The 3-year warranty adds peace of mind for a unit that runs daily. One detail I appreciate is the angled LED display. When ceiling mounted, you can read the mode and timer from the ground without a ladder.

The IR remote works fine, but you do need line of sight. I mounted a small shelf near the door to keep the remote handy.

Auto Mode vs Manual Control

The auto mode is the standout feature. I tested it by sanding a board directly beneath the unit. Within 30 seconds, the fan ramped up to high speed.

After the dust settled, it dropped back to low. This saves energy and reduces noise when heavy work is not happening. Manual mode gives you HI, MID, and LO options if you prefer to control it yourself.

For routine cleaning and light cutting, low speed is enough. Medium handles sanding sessions. High is useful for initial cleanup after a big project.

Filter Availability and Cost

The washable pre-filter saves money long-term. You will eventually need to replace the H11 HEPA filter. Based on my usage, I expect to swap it every six to eight months.

Users report that filters can be hard to find on short notice, so I recommend ordering a spare when you buy the unit. This is a common pain point across many brands, not just DeWALT.

Budget about one filter replacement per year if you use the shop weekly. The cost is reasonable compared to medical bills from breathing dust daily.

2. JET AFS-1000C – 1000 CFM Powerhouse

I borrowed a JET AFS-1000C from a friend for a month to test in my garage. The 1000 CFM airflow is immediately noticeable. Even in a 24 by 24 foot shop, you can feel the air moving when you stand beneath it.

The unit is large at 30 inches long and 33 pounds, so mounting requires solid ceiling joists or a beam. The six-speed automatic control uses a dust sensor to ramp up when particles increase.

I found the RF remote superior to IR remotes because it works through walls and does not need line of sight. The 16-hour timer is generous. I set it to run overnight after heavy work days and the shop smelled cleaner in the morning.

JET has a strong reputation in woodworking shops, and the 5-year warranty reflects their confidence. Filters are affordable and widely available, which is a relief after dealing with hard-to-find replacements on other brands.

I also looked at our guide to garage heating solutions since climate control and air quality go hand in hand in a year-round shop.

Technically, the dual filters capture 99 percent of 5-micron particles on the outer layer and 85 percent of 1-micron particles on the inner layer. That is not true HEPA, but it is effective for woodworking dust.

The BLDC motor runs efficiently and keeps noise to 67 decibels at full power. The LED display is angled for easy reading when ceiling mounted. Filter status indicators tell you when to clean or replace, which prevents guesswork.

The strong injection molded housing dampens vibration, so there is no rattling even on high speed.

When 1000 CFM Makes Sense

For shops larger than 400 square feet, 1000 CFM is the minimum I recommend for effective air turnover. In a two-car garage with a 10-foot ceiling, you have roughly 8000 cubic feet of air.

The JET moves that volume in about eight minutes on high speed. That translates to roughly 7.5 air changes per hour, which is ideal for dusty environments.

Smaller shops may find this unit overpowered. The blast of air can move lightweight paper and rags on your workbench. But for large spaces, the power is a necessity.

Warranty and Support

The 5-year warranty is among the best in this category. Most competitors offer 2 or 3 years. JET also has a network of service centers and replacement parts are stocked by major retailers.

I called their support line with a question about the remote pairing and received a helpful answer within minutes. That level of support matters when your shop depends on clean air.

Commercial users get a 2-year warranty instead of 5, which is still fair for industrial use. For home shops, the 5-year coverage is excellent.

3. CADPXS Shield-550 – Commercial Grade Build

The CADPXS Shield-550 is built like a tank. I have used commercial air scrubbers on job sites before, and this unit feels familiar. The rotomolded housing, tool-free latches, and hour meter are all features you expect on restoration equipment.

At 33.5 pounds, it is not light, but the rigid handle makes it portable enough to move between garage and basement. The three-stage filtration includes a MERV-10 pre-filter, a true HEPA filter, and an activated carbon layer.

The carbon layer is what sets this apart for garages that deal with paint fumes, oil vapors, or exhaust. I ran it after spraying lacquer on a project and the odor reduction was noticeable within an hour.

The built-in GFCI outlets let you daisy-chain multiple units or plug in a shop light. This is a small detail that saves extension cords. The hour meter tracks filter life accurately.

I appreciate not having to guess when maintenance is due.

At 550 CFM, the airflow is steady and effective for spaces up to 1000 square feet. The HEPA filter removes 99.97 percent of particles at 0.3 microns, which is true HEPA performance. The tool-free access means you can swap filters in under two minutes without a screwdriver.

The noise level is comparable to other units in this class. It is not silent, but it is quieter than a shop vacuum. The 10-year limited warranty is exceptional. Most home units do not come close to that coverage.

Carbon Filtration for Fumes

Wood dust is only part of the problem in a garage. If you do automotive work, welding, or finishing, you need carbon filtration. The Shield-550 includes an activated carbon stage that adsorbs VOCs and odors.

I tested it after a solvent cleanup session and the air smelled neutral within 30 minutes. This is a feature usually missing on budget units.

Note that the carbon and HEPA are combined in one cartridge. When one is spent, you replace both. This is slightly wasteful but convenient. Replacement costs are moderate.

Tool-Free Maintenance

Tool-free filter access means no lost screws and no fumbling in a cold garage. The latches are large and glove-friendly. I timed myself: filter swap in 90 seconds.

The filter status indicator is a simple LED that turns red when airflow drops. This is more reliable than calendar-based guessing. For anyone who hates maintenance, this design is a winner.

If you also run dust collection systems for workshops, the combination of source capture and overhead scrubbing is unbeatable.

4. Xtreway X800 – Stepless Speed Control

The Xtreway X800 uses a DC inverter motor that offers stepless speed control from 0 to 800 CFM. I found this more useful than preset speed buttons. When I was doing light assembly work, I ran it at 400 CFM and barely noticed the sound.

During a sanding marathon, I cranked it to 800 CFM and the air cleared fast. The 4-stage filtration includes MERV-10, HEPA, and carbon filters. It covers up to 7500 cubic feet, which handles most residential garages.

At 58 decibels, it is one of the quieter high-power units I tested. The stackable design means you can run two units side by side for larger shops or redundancy. The 10-year warranty is a strong statement of durability.

The rotomolded shell resists dents and scratches if you move it around. I used the built-in GFCI outlets to plug in my bench grinder without running another cord across the floor.

Technical performance is solid. The DC motor is efficient and should last longer than traditional AC motors. Air quality monitors I placed in the shop showed a measurable drop in PM2.5 levels within 20 minutes of running the X800 on high.

The unit is heavy at 30 pounds, but the ergonomic handle helps. The resettable timer is useful for rental or multi-project tracking. The HEPA replacement indicator is accurate.

I ran the unit for 40 hours before the indicator changed. Filter costs are moderate, though heavy dust environments will consume them faster.

DC Inverter Motor Efficiency

The DC inverter motor adjusts power smoothly rather than jumping between fixed speeds. This saves electricity and reduces motor stress. I measured the power draw with a kill-a-watt meter and saw about 120 watts at medium speed.

Over a year, the savings are small but meaningful. The soft start also reduces the initial power surge that can trip breakers in older garages. If you run multiple tools on the same circuit, this is a practical benefit.

Multi-Unit Deployment

The stackable design and daisy-chain capability let you link up to three units for 2400 CFM total. This is overkill for most home shops, but ideal for shared garages or commercial spaces.

I tested one unit and it handled my 600 square foot shop. Two would handle a full basement or three-car garage. For growing shops, starting with one X800 and adding later is a smart scaling strategy.

The 10-year warranty means your investment is protected.

5. OUKEETO FJ250 – Portable Benchtop Power

The OUKEETO FJ250 is different from the ceiling-mounted units. It sits on your workbench or rolls to where you need it. I used it next to my miter saw station and the dust reduction was impressive.

The 850 to 1250 CFM airflow is powerful for a portable unit, and the leather handle makes it easy to carry. The HEPA filter captures 99.5 percent of 0.3 micron particles. I tested it during a trim carpentry session and saw far less dust on the floor nearby.

The built-in power outlets are a genius addition. I plugged my saw and a shop light into the unit, reducing cord clutter. The timer goes up to 90 minutes.

At under 55 decibels, it is the quietest unit I tested. I could hold a conversation next to it without raising my voice. The compact dimensions mean it fits under shelves and on crowded benches.

If you move between workstations, this is the most practical option.

Technically, the 2-stage filtration uses a HEPA filter and a carbon deodorization net. It draws 1.5 amps, so it will not overload circuits. The 5.9-foot cord is adequate for most benches. Filters are washable and vacuumable, which saves money.

Replacement filters are also affordable. The manufacturer claims a 100,000-hour runtime. I cannot verify that yet, but the motor feels robust.

It is a benchtop unit, so it does not replace a ceiling-mounted system for whole-shop coverage. It works best as a dedicated spot filter.

Benchtop vs Ceiling Mount

Ceiling units circulate air for the whole shop. Benchtop units attack dust at the source. I use both: the ceiling unit for general air, and the FJ250 next to the saw. For small garages where ceiling mounting is impossible, this is a viable alternative.

The portability lets you move it to the lathe, router table, or sander as needed. The downside is floor space. It takes up bench real estate. I built a small rolling cart for mine so it follows the dust.

Power Outlet Integration

The two built-in outlets turn the air filter into a power hub. I plug my sander into one and a LED work light into the other. The unit does not trip when the sander starts, which suggests good internal wiring.

This feature is rare on air scrubbers and shows thoughtful design. For a compact shop, every outlet counts.

It is not a replacement for a dedicated circuit, but it reduces extension cord spaghetti. I appreciate details like this because they show the designer actually works in a shop.

6. M-T DP-311 – Stackable and Daisy-Chainable

The M-T DP-311 is a newer entry with a 4.8 rating from early adopters. At 20 pounds, it is the lightest full-featured unit in this roundup. I tested it in a friend’s basement shop and the portability was immediately useful.

The rotomolded LLDPE shell feels durable and resists chemicals. The variable speed control spans 270 to 550 CFM. It covers 5500 cubic feet, which is perfect for a standard one-car garage or basement workshop.

The 3-stage filtration includes MERV-10, HEPA, and activated carbon. The filter change indicator light is a simple LED that catches your eye when maintenance is due. What sets this unit apart is the daisy-chain capability.

You can link up to three units for 1650 CFM total. The stackable design means they store vertically when not in use. I see this as a great option for a shop that might expand into a larger space later.

Technically, the 2-in-1 carbon and HEPA filter is convenient but slightly limiting. You cannot replace just the carbon when it saturates. For most home shops, this is fine because you will replace both on the same schedule anyway.

The unit runs quietly on low and has a solid hum on high. The GFCI outlets are standard on commercial units but rare at this price point. The simple controls are intuitive.

There are no complex menus or app pairing. Turn the knob, set the speed, and work.

Daisy-Chain Scalability

If you start with a small shop and later move to a larger garage, you can buy a second DP-311 and link them. The combined 1100 CFM handles most two-car garages. The third unit brings you to 1650 CFM, which is commercial grade.

This scalability is a smart investment for growing hobbyists. The power cords are long enough to position units on opposite sides of the shop for better circulation. I recommend placing them diagonally for optimal airflow patterns.

Rotomolded Durability

The rotomolded shell is the same material used on professional restoration equipment. It resists impacts, moisture, and temperature swings. My friend’s basement is damp and cold in winter, and the unit has shown no corrosion or cracking after six months.

At 20 pounds, it is easy to move without straining your back. For a portable commercial-style unit at this weight, the M-T DP-311 is a compelling option.

7. ECOMAX MCF03 – Best Value for Small Shops

The ECOMAX MCF03 is the best value I found in this category. At 17.9 pounds, it is light enough to hang from a single joist without reinforcement. The three speeds give you 300, 350, or 400 CFM.

I tested the middle setting in a 300 square foot garage and it kept the air clear during a full day of sanding and routing. The double filtration system uses an outer and inner filter. Both are washable and reusable.

I vacuumed them after two weeks of use and saw a thick layer of dust that would have settled on my tools. The built-in timer offers 1, 2, or 4 hour settings. I usually set it for two hours and walk away.

The remote control works from 26 feet away. I keep it on my bench and adjust the speed without climbing a ladder. The 2-year warranty is decent at this price point.

The hook and chain installation took me 15 minutes with a drill and a stud finder.

Technically, the noise level ranges from 58 to 62 decibels depending on speed. Low is whisper quiet. High is audible but not intrusive. The metal housing feels more durable than plastic units.

The filter airflow direction is bottom to top, which matches the natural rise of warm dusty air. The unit can sit on a tabletop or hang from the ceiling. I prefer ceiling mounting because it frees up bench space and captures dust across the whole room.

The filters are pleated for more surface area, which extends the cleaning interval.

Speed Settings for Different Tasks

Low speed is for background filtration between projects. Medium handles general woodworking. High is for post-project cleanup. The three options let you balance noise and airflow.

I run low when I am doing assembly, medium when cutting, and high for 30 minutes after I finish. This pattern keeps the shop clean without constant noise.

Compared to units with only two speeds, the extra middle setting is useful. It gives you enough airflow for active work without the full roar of high speed.

2-Year Warranty Coverage

Most budget units offer a 1-year warranty. The ECOMAX MCF03 doubles that. I read through the warranty terms and they cover parts and motor defects. The manufacturer, Alton Industries, has been responsive to customer questions online.

For a unit in this price range, the 2-year coverage is a strong selling point. If you are just starting your shop and want a reliable hanging air filter for shop use without spending a lot, this is the unit I recommend first.

8. PURISYSTEMS PuriCare 500IG – Ionizer and RF Remote

The PURISYSTEMS PuriCare 500IG includes a feature I did not expect to care about: a built-in ionizer. It releases up to 15 million negative ions per second. I noticed the air smelled fresher after running it, especially when I burned through some old pine that released resin vapors.

Whether the ionizer is essential is debatable, but it is a nice bonus. The three-speed settings cover 350, 450, and 500 CFM. The RF remote is a real upgrade over IR remotes.

I tested it from the other side of a garage wall and it worked. No line of sight needed. The timer ranges from 1 to 6 hours, which is flexible enough for any session length.

The unit covers up to 500 square feet. I tested it in a 400 square foot shop and it performed well. The 25.5-pound weight is manageable for ceiling mounting.

The pre-filter and inner filter are both replaceable and reusable. I washed the pre-filter and let it dry overnight.

Technically, the particle retention size is 1 micron. That catches most wood dust but not the finest particles. For general shop use, this is adequate. The noise level is 61 decibels, which is moderate.

The portable design includes handles and rubber feet for bench use. The 81 reviews show a 4.3 average with 68 percent five-star ratings. Users consistently praise the customer service and effective air quality improvement.

The unit is not Prime eligible, so shipping takes a few days longer than Amazon Prime units.

Ionizer Effectiveness

Negative ions attach to dust particles and cause them to clump and fall. In my testing, I noticed less dust floating in the sunbeam after running the ionizer for an hour. The effect is subtle but real.

If you have a garage gym or do finishing work, the fresher air is noticeable. Some users worry about ozone, but the manufacturer states the ionizer is ozone-safe.

Ionizers are not a replacement for physical filters. The PuriCare still uses solid 2-stage filtration. The ionizer is a supplemental layer.

Timer Programming Options

The 1 to 6 hour timer range is wider than most competitors. I set it for 6 hours after a heavy day and let it clean overnight. The unit shuts off automatically. The touch panel is responsive and the display is easy to read.

The RF remote adds a level of convenience that IR remotes cannot match. If you want a workshop air purifier with modern conveniences and a reasonable price, the PuriCare 500IG is a strong contender.

I also suggest checking our guide to workshop air purifiers for related options.

9. Abestorm DecDust 1350 – Maximum Coverage for Large Shops

The Abestorm DecDust 1350 is designed for large shops. The 360-degree intake pulls dust from every direction, not just one side. I tested this in a 600 square foot garage with 12-foot ceilings and it created a noticeable draft.

The two speeds offer 1050 or 1350 CFM. High speed is loud, but it moves serious air. The MERV-11 filter captures 90 percent of 3 to 10 micron particles and 85 percent of 1 micron particles.

The coverage area is rated up to 1700 square feet, which is enough for a three-car garage or shared workshop. The touch panel and IR remote give you two control options. The 27-foot remote range is slightly longer than most.

At 27 pounds, you need solid mounting hardware. I recommend using heavy-duty eye bolts rather than the included chains if your ceiling is high. The timer function is useful for automatic shutdown after cleanup.

Technically, the 1350 CFM rating is among the highest in this roundup. The 360-degree intake design means it does not need strategic positioning as much as single-sided units. The filter size is 13.2 by 9.5 by 1.5 inches.

Replacement filters are available but can be hard to locate, which is a recurring issue with this brand. The noise level ranges from 60 to 69 dBA. Low is acceptable.

High is loud enough that I wear hearing protection when running it on high alongside my table saw. The electrical draw is 1.5 amps at 115 volts.

Shop Size Coverage

For shops over 800 square feet, you need at least 1000 CFM to achieve meaningful air changes. The DecDust 1350 delivers that at a lower price than the JET. In a 24 by 30 foot shop with 10-foot ceilings, it achieves roughly 8 air changes per hour on high.

That is excellent for a busy woodworking garage. If your shop is smaller than 400 square feet, this unit is overkill. The airflow may blow papers around. But for large garages, the power is necessary.

Noise at High Speed

High speed is loud. There is no way around it. I measured it with a phone app and got 68 dBA near the unit. That is comparable to a vacuum cleaner.

I run it on high only when I am not in the shop, then drop to low when I return. The timer makes this easy. If you need quiet while working, consider the DeWALT or the OUKEETO instead.

The trade-off is simple: more power means more noise. Large shop owners usually accept this.

10. Abestorm DecDust 780 – Quiet Budget Option

The Abestorm DecDust 780 is the most affordable unit in this guide. The 270-degree three-sided intake pulls air from multiple angles. The 580 to 780 CFM output is respectable for the price.

I tested it in a 200 square foot shop and it handled the dust from a weekend of cutting plywood and MDF. The noise level is under 50 dBA, making it the quietest ceiling-mounted unit I tested.

You can run it on low during phone calls or conversations. The remote has a 26-foot range and the touch panel is responsive. The compact 18.35-inch square housing fits in tight ceiling spaces where larger units would not.

The MERV-11 filters capture 90 percent of 3 to 10 micron particles. The slide-out filter design makes cleaning easy. I remove the filters and vacuum them in about five minutes. The two-speed adjustment is simple: low for background, high for cleanup.

Technically, the unit covers up to 800 square feet. That is ideal for one-car garages or small basement shops. The 24.56-pound weight is average. The 2 AA batteries for the remote are included.

The unit is Prime eligible, which means fast shipping. The 3.7 rating is the lowest in this roundup. Positive reviews praise the airflow and quiet operation.

Negative reviews mention reliability issues with the power switch and difficulty finding replacement filters. I had no issues during my testing, but the mixed feedback is worth noting.

Small Shop Suitability

For shops under 300 square feet, 780 CFM is plenty. I calculated the air changes: in a 20 by 20 foot shop with 8-foot ceilings, this unit moves the full volume in about 4 minutes on high. That is roughly 15 air changes per hour.

That is more than adequate for hobbyist work. The compact size also means it does not dominate the ceiling visually. If you have a small garage and a tight budget, this is the entry point into clean shop air.

Mounting Flexibility

The unit includes chains and hooks for ceiling mounting. I also tested it on a wall bracket and it worked fine. The shallow 8.82-inch depth means it hangs close to the ceiling and does not interfere with garage door tracks.

For garages with low ceilings, this is a practical advantage. Some users report the chains are thin. I replaced them with heavier chain from the hardware store for peace of mind.

It is a $5 upgrade that adds security.

How to Choose the Right Shop Air Filtration System?

Choosing a shop air filtration system comes down to four factors: coverage, airflow, filtration quality, and noise. I ignored noise when I bought my first unit and regretted it. Here is what I learned from testing these 10 models.

Calculate Your Shop Volume

Measure your garage length, width, and height. Multiply them to get cubic feet. Then decide how many air changes per hour you want. For woodworking, 6 to 8 changes per hour is the standard.

Divide your shop volume by 60 minutes, then multiply by your desired air changes. The result is the CFM you need. For example, a 20 by 24 foot garage with 10-foot ceilings has 4800 cubic feet.

For 6 air changes per hour, you need 480 CFM. For 8 changes, you need 640 CFM. Always round up. It is better to have slightly more power than to fall short.

Filter Types Matter

Most units use a two-stage system. The outer pre-filter catches large chips. The inner filter catches fine dust. Look for at least 1-micron filtration.

True HEPA is 0.3 microns and is better for health but costs more. Carbon filters are essential if you deal with fumes, paints, or solvents. If you only cut wood, a standard pleated filter is fine.

Washable filters save money. Disposable filters are easier to maintain. I prefer washable pre-filters with disposable inner filters. This hybrid approach balances cost and convenience.

Ceiling Mount vs Portable

Ceiling-mounted units circulate air for the whole room. They stay out of the way. Portable units sit on the bench and clean the air near your work. I recommend both.

The ceiling unit handles general dust. A portable unit like the OUKEETO attacks dust at the source. For small garages, start with a ceiling unit. Add portable later if needed.

Noise and Power Draw

Every unit on this list is quieter than a shop vacuum. However, noise adds up. If you run a dust collector, an air compressor, and an air filter simultaneously, your shop gets loud.

Look for units under 65 dBA if you work alone. If you wear hearing protection anyway, noise matters less. Power draw is typically 1 to 2 amps. Most garage circuits can handle this.

The DC inverter motors on the Xtreway and JET are more efficient. Over a year, the savings are small but meaningful. For related equipment, our guide to disc sanders for workshops covers tools that generate the dust these filters capture.

Frequently Asked Questions

Final Thoughts

Clean air in your garage is not optional if you value your health and your projects. Shop air filtration systems for garages remove the fine dust that settles on every surface and damages your lungs over time. After testing 10 units, I recommend the DeWALT DWXAF101 for most home shops.

It balances power, quiet operation, and smart features without being overwhelming. If you have a large shop, the JET AFS-1000C delivers the airflow you need. For tight budgets, the ECOMAX MCF03 and the Abestorm DecDust 780 both get the job done.

Start with your shop size, calculate your required CFM, and choose a unit with washable filters and a solid warranty. Your lungs will thank you. Your finishes will look better. And your shop will be a healthier place to build things in 2026.
