Small Shop Dust Collection (What I Chose and Why)

Discover why I chose a wall-mounted dust collection system for my small shop in this easy-to-understand guide. Supply list included.

I'm sharing the space-saving dust collection system that I use in my small shop, including the wall-mount dust collector, cyclone separator, and more.

One of the questions I’m often asked is, “what do you use for dust collection in your small workshop?”

Until now, I haven’t shared my system because I didn’t believe it was the best solution. However, I completely overhauled my dust collection, and I’m taking you behind the scenes to look at the space-saving solutions I use to banish dust in my small workshop.

Sawdust, especially fine dust, can be harmful to your lungs. Not only can it be dangerous, but sawdust is also messy and time-consuming to clean up.

While I always wear a respirator and use a dust collection while woodworking, I haven’t discussed my setup because I wasn’t fully satisfied with it.

Before I focused on maximizing space in my small workshop, I bought a Central Machinery dust collector at Harbor Freight.

The Harbor Freight unit worked but was too big, taking up an entire corner of my tiny workshop. Even though it was on wheels, I rarely moved it. The area behind the collector was wasted space, becoming a black hole for cutoffs and lost tools.

Making matters worse, removing the enormous dust bag was no easy feat. Its size and weight, combined with my shop’s narrow entryway, turned a simple task into a real struggle.

I’ve been planning a makeover of the wall where I keep my miter saw. Right now, I’m using a folding, portable miter saw station similar to this one. I plan to make a larger, fixed miter saw station that would extend to the dust collection area. The giant Harbor Freight unit had to go to start the makeover on the miter saw area.

I looked at smaller, wall-mounted options and decided to buy this Grizzly wall-mount dust collector.

Below I’ll share considerations for choosing a dust collection system for a small shop. After each section, I’ll share what I chose for my shop and why I made that decision. I’ll also share how I set up the system, including a complete supply list.

Small Shop Dust Collection Considerations

There are several things to consider when thinking about how to manage the sawdust in your workshop, such as:

  • Your shop’s size
  • The tools you’ll connect to a dust collection system
  • Your budget

There are two more considerations: CFM and horsepower. CFM is Cubic Feet per Minute, and it’s a measurement of airflow. Horsepower is a measurement of power.

There are lots of articles out there that do a way better job of explaining CFM and horsepower than I ever could. For example, I was reading a post in a woodworking forum about dust collection. One of the responses recommended this article by Wood Magazine that includes charts and worksheets to calculate your dust collection needs.

It’s a great article, but it was way over my head!

I used a very basic approach to decide on which dust collector to buy. I looked at the CFM requirements of my tools, and compared those requirements to the CFM ratings of the dust collectors I was considering. Then I chose a dust collector with a CFM rating greater than the CFM requirements of my tools.

Size of Workshop

The size and configuration of your workshop will impact what you choose to use for dust collection. 

Working in a small shop like mine presents challenges that larger spaces might not face, such as low ceilings, limited wall space, or both.

In a large workshop, long runs of ducting can reduce the efficiency of a dust collector. Long runs of ductwork are not as much of a problem with a small workshop. My shop is about the size of a small bedroom, so the dust collector is only a few feet from each machine. Plus, my tools are on wheels, so that I can move the tools closer to the dust collector.

One of the biggest concerns for a small workshop is the size of the dust collection unit. Floor space and wall space are at a premium in a small shop. A big stationary dust collector, like my Harbor Freight unit, takes up too much floor space and wall space in a tiny shop.

What Tools

What tools do you want to connect to a dust collection system? For me, the tools I use the most, and my biggest sawdust makers, are my miter saw, random orbital sander, and table saw. Occasionally I’ll use my circular saw, jointer, or thickness planer mounted on this flip top tool stand.

After you decide what tools you want to connect to the system, you can look at a chart (or your owner’s manual) to determine the CFM requirements for those tools.

The Central Machinery unit was rated at 1550 CFM. This smaller wall-mounted unit I was looking at was rated at 537 CFM.

So I knew it was going to be a tradeoff between space vs. suction capacity. For me, space won out. That big stationary unit was preventing me from building my new miter saw station, which would make my shop a better place to work.

Budget will also play a role in your dust collection system. You’ll need the dust collector, fittings, hoses, blast gates, etc., to make the system work. I planned to repurpose much of the hoses and fittings from my old system, so I had to buy only a few new things.

But generally speaking, the higher the CFM, the more expensive the system will be. Also, wall-mounted units are usually more expensive than a similar stationary unit

Small Woodshop Dust Collection Options

There are three options for dust collection:

  • Dust collector
  • Shop Vac
  • Dust extractor

Dust collectors are HVLP, high volume, low pressure. In other words, HVLP is high airflow, low suction.

Shop Vacs are HPLV, high pressure, low volume. In other words, HPLV is high suction, low airflow.

This means the high suction of a Shop Vac can pick up heavy debris, like rocks off the floor mat of your car, but the low airflow means the hose needs to be close to what you’re trying to pick up.

The low suction of a dust collector has trouble sucking up heavy debris, like metal, but the high airflow will easily pick up light debris, like sawdust and wood chips.

Dust Collector

Dust collectors work well for large woodworking machines like:

  • Table Saws
  • Jointers
  • Thickness Planers

Dust collectors are available as:

  • Stationary units
  • Wall-mounted units
  • Mobile floor units

A wall-mounted collector is a good option for a small workshop. It hangs on the wall, which frees up floor space. Also, it hooks on a bracket, which means it can be easily removed from the wall and moved to another location.

Shop Vac

Shop Vacs work well for smaller tools with smaller dust ports like:

  • Miter saws
  • Router tables

And handheld tools like:

  • Circular saws
  • Sanders

The advantage of a Shop Vac is they don’t take up much space, and they are mobile. It’s the least expensive option for dust collection. Plus, it’s multi-purpose, which means you can use it for other projects like cleaning the trunk of your car or vacuuming up a 5-pound bag of flour that spilled in the kitchen.

The downside to a Shop Vac is that it can’t do dust collection for an entire shop. And it really only works for one tool at a time.

Dust Extractor

It looks similar to a Shop Vac, but it’s not a multitasker. Unlike a Shop Vac, it’s exclusively designed to pick up dust.


The filter that you use with your dust collection system will also have an impact on your system.

My Harbor Freight dust collector came with a filter bag that was rated for about 30 microns. That means anything smaller than 30 microns was blowing back into the air. Filter bags are not the best option because fine dust ends up in the air.

One of the first upgrades I made to my Harbor Freight unit was to add a canister filter. A canister filter has up to six times the surface area of a filter bag and does a better job of trapping fine dust.

The upgraded filter was rated for about 5 microns. The filter of this Grizzly wall-mounted dust collector that I bought was rated for 1 micron. The 1-micron filter will trap smaller particles, but it will also have less airflow than the 5-micron filter.

With use, dust will cake on the pleats of the filter and is called dust cake. Dust cake helps improve filtration. That said, the loose dust should occasionally be cleaned off. The Grizzly wall-mount dust collector includes a filter cleaning handle. Turning the handle knocks off the loose dust that has collected on the filter.

Filter bags are usually the least expensive filter. And a 1-micron filter is usually more expensive than a 5-micron filter. In other words, the more you want to filter, the more you’ll pay.

Single-Stage vs. Two-Stage

Using a dust collector, Shop Vac, or dust extractor by itself is called a single-stage system. A two-stage system combines a dust collector, Shop Vac, or dust extractor with a cyclone separator.

A cyclone separator, sometimes called a chip separator or dust separator, separates chips and heavier dust into a removable container. Separating the heavier dust before it reaches the filter helps your filter to stay cleaner. Keeping your filter clean provides maximum airflow and reduces how often you’ll need to change the bag.

What I Chose: Wall-Mount Dust Collector

For my new dust collection system, I chose this Grizzly Wall-Mount Dust Collector. This 1 HP unit has a canister filter rated for 1 micron. The canister filter has a handle that knocks off the loose dust that has caked on the filter’s pleats. The handle is a great feature that the aftermarket filter on my Harbor Freight unit didn’t have.

📝 NOTE: I’ve read some reviews from people who had trouble keeping the bag on the collector; however, I have not experienced this issue.

I wasn’t using a dust separator with my Harbor Freight collector, so when I bought my wall-mounted dust collector, I also purchased this cyclone separator. In less space than my Harbor Freight collector occupied, I now have a dust collector and cyclone separator.


Ducting or ductwork is what carries the sawdust and chips from the machine to the dust collector. There are three common types of ducting: flexible hose, PVC pipe, and metal pipe.

Before we look at the differences in the types of material, we should consider the ductwork layout.


As I mentioned earlier, there are lots of articles out there that can do a better job of describing CFM, etc. 

The same goes for laying out the ducting. But I will say that sometimes in a small shop it’s challenging to follow the guidelines. I mentioned that I only have one wall to mount the dust collector, and the ceilings are low. Sometimes you can only do the best that you can do.

I did my best to avoid sharp bends and tried to use gentle curves instead.

Flexible Hose

A flexible hose is one of the easiest to run. Just lay it out, cut it, and connect with hose clamps. The downside to a flexible hose is that it’s not as efficient over a long run. 

The corrugated walls reduce the airflow. Wood chips are more likely to get caught on the corrugated walls and cause a blockage. Blockages are less likely with the smooth walls of PVC or metal.


PVC pipe has smooth walls, which improves airflow and is less likely to have a blockage. These advantages come at a price. PVC is usually more expensive than a flexible hose.


Metal pipes, like PVC, also have smooth walls. It’s the most expensive option and is usually found in commercial workshops.

Static Electricity

Flexible hose and PVC pipe have the possibility of creating static electricity. This static electricity can cause the sawdust to spark and cause a fire. I’ve read articles that say a dust collection system must be grounded, and other articles say that a spark caused by static electricity is unlikely.

I think these grounding kits are cheap insurance. Out of an abundance of caution, I will ground my system.

Blast Gates

A blast gate is a sliding door that connects two sections of pipe or hose.

Blast gates control the airflow of a dust collection system. It focuses the airflow to the tool you’re using and closes off the airflow to machines that are not being used.

Blast gates are available in plastic or metal. Metal is a better option, but metal blast gates are more expensive than plastic.

What I Did

I had flexible hose that I used with my Harbor Freight collector, so I reused it with the wall-mounted dust collector.

I know the flexible hose is not ideal because it will sacrifice some performance, but I have a lot of it. Perhaps in the future, I will upgrade to PVC ducting.

I also had a handful of plastic blast gates from my previous setup that I will reuse with my new setup. Again, I may upgrade to metal blast gates in the future.

I will use one of these grounding kits to ground the ducting.

Optional Accessories

Wireless Remote Control Outlet

Barry, a long-time reader and a woodworking friend I met through this site, shared that he uses a wireless remote control outlet similar to this one for several tools in his workshop. The remote turns machines on and off, like a dust collector from just about anywhere in the shop.

When the switch broke on my Central Machinery dust collector, I bought one. I emailed Barry and said thank you for the suggestion and wondered why I waited so long to buy one!

Port Adapter

Hose diameters come in lots of sizes 2-1⁄2″, 1-7⁄8″, 1-1⁄2″, and 1-1⁄4″. A port adapter like this one allows you to connect your dust collection system to just about any tool.

HEPA Filter

A HEPA filter helps to trap fine sawdust. Many brands offer a HEPA filter for their Shop Vac.

Setting Up Dust Collection for a Small Shop (My System)

The owner’s manual for the Grizzly Wall-Mount Dust Collector says the wall bracket needs to be mounted a minimum of 56 inches from the floor. 

I attached a support board between two studs about 61 inches from the floor. I covered the studs with tongue and groove boards that I had leftover from another project.

Next, I attached the wall bracket to the support board using 3″ lag screws.

Then, the dust collector was attached to the wall bracket.

I built a platform for the cyclone separator. The floor of my shop occasionally gets damp with groundwater. The platform keeps the paper container off the floor. 

The platform also provides a space for the floor sweep. The classroom where I took my furniture-making classes had one of these, making it quick and easy to clean up the shop.

  1. I see that you are using a fiberboard (cardboard) drum under the cyclone unit. How are you keeping it from collapsing under suction? I built a cyclone based system using a shop-vac and 2-inch hoses (the size of the outlets on most of my machines.) Shortly after starting it up, the barrel collapsed. I started with a heavy food grade poly barrel and moved to the fiber one. I didn’t want to move to a steel drum due to weight considerations so I installed a series of ribs into the fiber drum.

    Just wondering if you’ve had the same or similar trouble.



    1. Hi Ray – I’ve read reviews where the container has collapsed for some people, so I was apprehensive about buying it. I would have preferred a plastic container, but so far, this fiberboard container has not collapsed for me.

  2. Hi Scott,
    Very good tips as I am facing the same issues with my small workshop and long-technical articles are way over my head, so this simple and precise advice is very appreciated! Keep going!
    Best regards from Spain.

  3. wow, a write up like this is so incredibly useful to a beginner. It is great to go through the whys and not just the hows and how muchs. absolutely love how you strung the various pieces together, logically, one leading to the next. really appreciate all the effort you put in to share your knowledge. more power to you, and best wishes for your projects..THANK YOU!
