Main Differences Between a Shop Vac and Dust Extractor
The main difference between a shop vac and a dust extractor is the level of suction and filtration. Typically a dust extractor will have a two-stage HEPA filter to capture large and small particles of dust. Whereas a shop vac only has standard filters and doesn't control dust from escaping into the air. Dust extractors also have a higher level of suction due to a more powerful motor and typically come with adjustable suction. Overall, a shop vac is more like a regular vacuum for large debris or standing water, and a dust extractor is designed to capture dust produced by woodworking tools.
Which is Better a Shop Vac or a Dust Extractor?
To identify which is better a shop vac or a dust extractor you first need to identify the type and amount of dust you're dealing with. If you're like me and use a lot of handheld power tools or sanders, they typically blow dust into the air which could cause serious respiratory problems. In that case, a dust extractor would be better since they are designed to capture dust at the source and trap particles as small as 0.3 microns. However, if you don't do a lot of woodworking or sanding and need to just pick up large amounts of debris and wood chips then shop vacs are better in that case.
Shop Vac Advantages
Shop vacs do have a few advantages over a dust extractor and are helpful to quickly clean up a jobsite or spill. Shop vacs are specifically designed to pick up large debris or larger particles of dust. Good shop vacs can also be used to clean up water or wet messes, and are sometimes called a wet dry vac. I personally have used my shop-vac to help a friend clean up his flooded basement, something I would never think about doing with my dust extractor.
Shop Vac Disadvantages
The biggest disadvantage of a shop vac is that they don't capture airborne particles of dust and their noise level is extremely high. Shop vacs are primarily designed for general cleanup and not to capture smaller particles of dust from woodworking. Using a shop vac with a sander or other woodworking tool may cause a bigger risk by blowing out large amounts of dust into the air. Also, shop vacs don't have standard-size hoses, and it's very hard to find adapters to fit your power tools.
Dust Extractor Advantages
Dust extractors have quite a few important advantages over shop vacs, especially for a woodworker. Most extractors are equipped with a HEPA filter that can capture fine dust and airborne particulates at the tool. Dust extractors also are able to filter more air volume with up to 150 CFM or cubic feet per minute. Another advantage is that most manufacturers have a standard hose size and supply adapters for a variety of tools. With a powerful dust extractor, you will be able to capture nearly all the small particles of dust when sanding reducing your risk for respiratory issues.
Dust Extractor Disadvantages
Even though a dust extractor may seem like the best for woodworking there are a few instances where there is a better tool. If you use a dust extractor to collect a lot of dust from stationary machines the collection canister will fill up fast. A dust extractor is primarily designed for smaller tools whereas a dust collector is best for larger machines. Also, most dust extractors are considered industrial vacuum cleaners and are used in commercial environments making them expensive.
Tool Comparison
Capability
The main difference in capability between an extractor and a dust collector is the ability to be used on water. A dust extractor is primarily a dry vacuum but can be used occasionally for water. However, if you use an extractor you will need to remove the HEPA filters and extended exposure to moisture could cause issues with the motor. A shop vac on the other hand is capable of sucking up inches of water with no issue. When it comes to dust control the extractor is a more powerful tool and is capable of capturing fine dust.
Time Savings & Speed
In the long run, a dust extractor will save you a lot more time and speed up your projects. Most dust extractors are equipped with an automatic outlet that allows your power tool to turn on and off the extractor remotely. Also, when you use a shop vac for woodworking, I found myself spending a long time cleaning up after projects and I always had a film of dust on all my tools. Depending on your tools and dust extractor, you could potentially save a lot of work by not having to switch out adapters and nozzles.
Dust Collection
When it comes to dust collection, the choice between a dust collector and a shop vac can make a big difference. A dust collector by far has a more powerful motor and is designed to handle wood chips from a planer or jointer and a high volume of wood dust. On the other hand, a shop vac is great for general cleanup, but not specifically built for dust collection. Shop vacs lack components like a dedicated HEPA air filter for finer dust particles and the capacity and suction power for larger tools. You could however upgrade your shop vac with a cyclone separator or a dust deputy to separate the larger dust particles from entering your collection bags. I personally did this for a while before upgrading to a larger dust collection machine. The choice between the two ultimately depends on the number of tools in your wood shop and the amount of dust you're generating.
Portability & Size
In terms of size and portability, the differences between a dust collector and a shop vac are not very apparent. Most dust extractors and shop vacs come in similar sizes but typically shop vacs are larger and a common choice for a job site or large shops. However, if you're requiring HEPA filtration or primarily using a vacuum for woodworking, a dust extractor will offer the most flexibility and better use of space. Dust extractors are generally more portable with compact designs that can also double as mobile base for additional tool storage depending on the brand. I personally would use a dust extractor for both a small shop and a job site rather than a shop vac due to the additional features, design and HEPA filtration.
Price Comparison
When comparing the price of a dust extractor and a shop vac, an extractor is more expensive. Depending on the size a shop vac typically costs around 75 to 150 dollars. In comparison, a dust extractor will cost anywhere from 400 to 1,000 dollars. Typically they all have the same features but range in size. Another aspect to consider is the cost of the dust bags for extractors will be significantly more than vacuum bags for shop vacs. Also, shop vac filters will be less expensive than the HEPA filters on a dust extractor. Even with the increased cost a dust extractor is worth the money for a woodworker.
Should you buy a Shop Vac?
A shop vac is a useful tool for certain tasks in a workshop but not all, so it really depends on your needs. Unlike dust extractors, shop vacuum units have the versatility to pick up both larger particles and wet debris. However, they struggle with very fine dust from sanding and any woodworking tools due to the limited capability of the filters. Keep in mind, due to the nature of how shop vacs work they are very loud so if you do use it instead of a dust extractor I would recommend getting some hearing protection especially if you are sanding. I have found using a cordless vacuum to clean up areas in my shop helpful so I don't have to drag my dust extractor around. So to answer the question if you should buy a shop vac, I think you do need a shop vac around the house and your shop but not for sanding or as a dust extractor or collector. I personally started with a dedicated shop vac when I began woodworking and it worked to an extent, but it left me with fine dust all over my garage and probably in my lungs.
Should you buy a Dust Extractor?
If you're serious about woodworking it's critical to prioritize your health and safety and to keep your shop clean, which makes investing in a dust extractor a smart decision. Unlike a shop vac, dust extractors or industrial dust collectors are specifically designed for woodworking, employing a 2 stage system with HEPA filters that effectively capture fine dust, which can lead to health issues over a prolonged period. Yes, dust extractors are more expensive than your typical shop vac, but they're purpose-built to handle sanding and stationary power tools. The higher upfront cost is offset by the long-term health benefits and a dust-free shop and clean air. So if you're considering buying a dust extractor, I personally think it's worth the investment and has made a major difference in my shop.
