What to Consider When Buying a Dust Collector
Before deciding on a dust collector, it is important to evaluate what you need. Put simply, your dust collector needs to pull more air (rated in cfm) than your most air-hungry tool (and the ductwork) requires. Other factors to consider include the level of air filtration and the collection bag capacity.
Beginner woodworkers (who have minimal capital to invest in large stationary tools) may want to consider a small dust collector. These portable machines are manageable and easy to move around the shop from tool to tool as needed. However, you’ll sacrifice the cyclone system that separates chips and dust, resulting in more dust reaching the pleated filter. This means cleaning the filter more often.
A simple upgrade with a significant impact is to replace stock bags with felt bags rated at five microns or less. Dust particles under 10 microns are the most harmful to your lungs, and standard bags are good at capturing particles of 25 microns or bigger. Also, check the noise output to ensure it’s not too loud.
“To choose the right dust collector, the user must understand the nature of the dust they are creating, where the dust is produced, and the volume of dust produced. The user must choose the appropriate dust collector for their specific job site application based on performance needs, desired product features and any local dust regulations. The Occupational Safety and Health Administration (OSHA) standards 1926.1153 and 1910 offer guidelines for respirable crystalline silica dust and wood dust,” notes Heather Lockhart, product manager for DeWalt.
Types of Dust Collectors
Several types of dust collection products are available, with the main differences being power, portability and dust collection capacity.
Shop vacs: This is an affordable option best used for smaller tools and to pick up random debris such as screws. You will have to empty the vacuum more often, and the filter clogs more frequently. The filtering capacity of a shop vac is not nearly as strong as a dust collector, but there are ways to improve it.
Dust Extractors: These are designed to collect dust from handheld power tools. Like the Festool HEPA version, they can be extraordinarily quiet and have a tool-activated switch that turns them on automatically.
Single-Stage Dust Collectors: Two-bag, single-stage dust collectors work by transporting sawdust and wood chips through an impeller to a collection bag. The heavier particles and debris then settle in the lower bag. They’re simple designs with a higher horsepower output that lets you connect to larger tools like a table saw or planer. They come in various designs: upright, wall-mounted or handheld.
Cyclonic Canister Dust Collectors: This type has a higher airflow and two-stage dust separation, separating smaller particles from larger pieces. As a result, the finer dust particles pass through the impeller and into the filter. The canister filter is excellent at capturing one-micron and two-micron dust particles effectively.

How We Found the Best Dust Collectors
I limited the selection of dust collectors and shop vacs with three microns or better filtration and dust collectors with pleated filters and heavy felt bags. I looked at the ease of assembly out of the box and how simple it is to empty and reattach the dust collection bag. I also considered collection bag capacity, power (CFM), and suction. Finally, I combed through airflow charts, decibel levels, and static pressure calculations to bring you the best dust collector and shop vac products for a shop of any size.
I started by unboxing and assembling each dust collector and wet/dry vac, noting how long the assembly took and whether the owner’s manual instructions were clear, lacking, or confusing. Then, I put the machines through their paces to test for the best and weed out the rest.
For shop vacs, I recorded the time it took each vacuum to suck up a mess consisting of sawdust, screws, nails, and chunks of wood with equal vigor. The other suction test was to fill a bucket with two gallons of water and see how long it took the shop vac to empty the bucket of water. Shop Vacs have many uses, often used in emergencies where time is a factor. So, I tested each model for difficult or confusing latches and complicated cord holders and checked to see if the hose and attachments fit together easily.
Most importantly, I used the dust collectors and shop vacs as they were intended—for cleaning up messes and a home renovation project. For dust collectors, I attached them to handheld tools and bigger equipment like a table saw and planer.
FAQ
How strong of a dust collector do I need?
Cubic feet per minute (CFM) and horsepower (HP) are two essential features to consider when determining the size of a dust collector you need. Horsepower determines the strength of the dust collector motor, and CFM is the amount of airflow the collector generates.
Medium-sized dust collectors typically have around one horsepower and 700 CFM. If your workshop has two or three power tools, a one-horsepower 700 CFM dust collector will be the smartest choice. Larger shops with multiple stationary power tools should use around one-and-a-half horsepower collectors with 1,200 CFM. The size of a workshop affects the amount of air volume (CFM) needed to effectively capture dust. Larger workshops request higher CFM ratings. Consider your peak usage when determining the strength of the dust collector. Will you be using multiple tools simultaneously or one tool at a time?
The ductwork and static pressure also determine how strong a dust collector you need. The more bends and obstacles in the ductwork, the higher the static pressure, which requires a more powerful dust collector to maintain adequate airflow.
Can you turn a shop vac into a dust collector?
Repurposing a shop vac as a dust collector can be a budget-friendly option for hobbyists or occasional users. Still, it’s essential to understand its limitations and consider whether it meets your needs and expectations for dust collection.
If you’re wondering, can wood make you sick? The short answer is yes, which is why dealing with dust is so important. But if a dust collector is too costly or bulky, you can make a budget system with just a few upgrades to your wet/dry vac. One upgrade is to add HEPA filtration to your shop vac.
When the HEPA filter and dust bag are used together, they remove 99.97% of all particles 0.3 microns and larger from the air. These dust bags are uniquely shaped like rings instead of the typical U-shaped bags. This allows for cyclonic airflow, meaning dust distributes evenly throughout the bag.
Another upgrade to your shop vac is a cyclone separator to keep the filter cleaner and make it easier to dispose of sawdust. A popular one is the Dust Deputy separator, which captures about 98% of the dust in the five-gallon bucket, leaving the filter on your shop vac cleaner and running more efficiently.
The shop vac can be attached to most large power tools, but it won’t be as effective as a dust collector since it may not provide the same airflow or suction power as a dedicated dust collector. You’ll find yourself cleaning out the dust receptacle of a shop vac much more frequently, especially with tools that create a lot of dust.
Technically speaking, the difference between a shop vac and a dust collector is that a shop vac is a high suction, low airflow (which is why you can suck a screw right off the floor with the narrow hose). A dust collector has high airflow and low suction (which is why lighter sawdust and wood chips will float down the wide hose, but it can’t pick up metal or large pieces).
A dust extractor is similar to a shop vac but can move a larger volume of air. It also has better filters, typically HEPA grade, that trap airborne dust down to 0.3 microns. Consider it a portable dust collector that you can take with you to the job site!
While repurposing a shop vac as a dust collector can be effective for smaller-scale projects and portable tools, it may not be as efficient or powerful as dedicated dust collection systems designed for larger woodworking or industrial applications. Regular maintenance is key. Clean or replace the filter and dust collection bag regularly for optimal performance.
“If possible, a dust collector should be fitted with a filter capable of capturing 1 micron particles of dust. Equally important is that any filter should be kept clean with agitation after every work day,” says Tom Noffsinger, a veteran woodworker of over 30 years.
What is a good CFM for a dust collector?
Cubic feet per minute (CFM) and horsepower (HP) are two essential features to consider when determining the size of a dust collector you need. Horsepower determines the strength of the dust collector motor, and CFM is the amount of airflow the collector generates.
Medium-sized dust collectors are typically around one horsepower and 700 CFM. If your workshop has two or three power tools, a one-horsepower 700 CFM dust collector will be the smartest choice. Larger shops with multiple stationary power tools should use collectors that are around one-and-a-half horsepower and 1,200 CFM.
Here’s a rough guideline:
Small Workshops or DIY Enthusiasts: A dust collector with a CFM rating of around 350 to 700 CFM should suffice for smaller workshops. These units are typically compact and suitable for handheld tools like sanders and routers.
Mid-Size Workshops: If you have a mid-size workshop and use larger stationary tools such as a table saw, planer or jointer, consider a dust collector with a CFM rating between 700 and 1100 CFM. This range provides sufficient airflow to capture dust generated by larger machinery.
Large Workshops or Commercial Settings: For larger workshops or commercial settings with multiple tools operating simultaneously, you may require a dust collector with a CFM rating exceeding 1100 CFM. High-capacity dust collectors like the Grizzly 1 HP dust collector with multiple intake ports or ductwork systems may be necessary to handle the increased volume of dust.
Once you have matched the dust collector’s CFM rating with the requirements of your specific tools and workshop setup, you will want to take into account the ductwork system, as this will also impact the overall performance of the dust collection system.
“A higher CFM means more air is moving, and more dust is being collected and filtered out of the air, or straight off the tool. Ultimately, as a hobbyist, you might want to shoot for something in the middle range of CFMs because it’s too low, and you’ll be disappointed and too high, and you won’t notice the difference for anything but the extra amount you paid. For most hobbyists, the minimum CFM required for efficient dust collection would likely be around the 350 range, whereas woodworkers with more projects, or ones that require more uptake, would likely need a CFM in the 800s to be safe,” says Brandon Walker, Superintendent at ASAP Restoration LLC.
