What Are The Similarities Between The Festool Dust Extractors?
Across the 9 different Festool dust extractor models there are a few similarities with the main one being filtration level. All the models are equipped with HEPA filters that can filter 99.97% of particles down to 0.3 microns in size. Also, all the models come with variable suction control to quickly dial in the right amount of suction for various tools. I personally never thought variable suction was needed but if you have too much power it could cause swirls and imperfections when using an orbital sander. All the corded dust extractor models are outfitted with a remote outlet that triggers the vacuum to turn on when a power tool is powered by the dust extractor, this feature however is not included on the battery operated extractors.
What Are The Differences Between The Festool Dust Extractors?
While most of the Festool dust extractors look very similar there are quite a few differences between the models. Recently, Festool USA released a new set of battery operated dust extractors which are the CTC models that are streamlined for job site performance. They also offer their AC line of high-performing extractors with auto-clean features to give you continuously high suction power and minimal maintenance. Their MIDI line also offers increased capability with a manual filter cleaning mechanism to help you quickly get back to sanding. Festool also offers Bluetooth capability to remotely turn on the extractor, with some of their models coming standard with the feature, while others can be upgraded with an add-on module and some cannot. One of the obvious differences between the models is the bag capacity and size of the extractor. Other differences which are outlined in the comparison chart are hose storage, systainer docking, cord length, weight, max volume flow, and if they come with an anti-static hose or other accessories.
Festool CT Dust Extractors
Festool CT MIDI I
The Festool CT MIDI I is a feature packed dust extractor in a compact form factor for increased portability. The dust extractor comes standard with a Bluetooth module, anti-static hose, variable suction, and a manual filter cleaning mechanism. The CT MIDI I is a great extractor for someone that needs portability but requires endless corded power and robust suction for larger power tools. The CT MIDI I has a max volume flow of 130 CFM which is right up there with the larger CT models. The only downside of the CT MIDI I is the smaller sized capacity of only 4 gallons or 15 liters. The dust extractor also comes with variable suction with 5 preset levels, whereas the other CT models have full customization of the suction power. When comparing the CT MIDI I vs the CT 15 there are a few differences with the biggest being the MIDI I includes hose storage or what Festool calls a hose garage as well as the ability to dock systainers on top of the extractor. In my opinion the Festool CT MIDI I is a great option if you need corded power with Bluetooth functionality but the portability of a smaller sized dust extractor.
Festool CT 15 (Best Budget Dust Extractor)
The Festool CT 15 is the cheapest and best budget option if you want a HEPA filter dust extractor, but it comes with a few downsides and a lack of some features. Due to the smaller footprint, the CT 15 doesn't have onboard hose storage or the ability to mount systainers on the top of the extractor. However, the CT 15 does have a rubber tie-down strap to secure the hose to the top. Another downside is the CT 15 is not equipped with Bluetooth capability and is not able to be upgraded with a Bluetooth module. The CT 15 does come with a crevice tool and upholstery brush as well as a dust hose and offers relatively the same level of performance as the larger CT models with 130 CFM volume flow. If you need something for a small shop and can live without a few of the storage features and Bluetooth functionality the CT 15 would make for a great investment and help keep your shop air clean.
Festool CT 26, CT 36, & CT 48 (Best Overall Dust Extractor)
The Festool CT 26, CT 36, and CT 48 models all share the same functionality and features with the only difference being the maximum volume of the dust bags. The CT 36 and CT 48 are just larger units with higher capacity with the number signifying the liter size of the machines with the CT 48 having 12.7 gallons of dust collection. The models all have hose storage on the top, the ability to mount systainers on the top, and cord management on the back. I wouldn't say they are the best machines for portability due to the size but they do have larger rear wheels which make it easier to move around and over debris. These models also don't come standard with Bluetooth but can be easily upgraded with an add-on kit for Bluetooth technology or even compressed air. All three come with anti-static dust hoses and fully adjustable suction with a maximum volume flow of 138 CFM. I personally have the CT 36 in my shop and I am honestly shocked at how well it does and did a full review of my experience. It captures nearly all the sawdust when it's connected to my sander or other power tools, whereas with a shop vac, I was getting a lot of dust in the air and all over my garage. If you’re interested in how well the CT models perform with a Festool sander I have detailed my full experience in another article. In my opinion, the Festool CT 36 model is the best overall dust extractor with a good balance between size, cost, and performance.
Festool CT AC Dust Extractors
Festool CT 36 AC & CT 48 AC (Best Performance Dust Extractor)
Within the CT model line up Festool offers two of its top dust extractors with a proprietary feature called Autoclean (AC). The feature is offered on both the CT 36 AC and CT 48 AC which is an auto-cleaning feature designed to eliminate clogged filters and give you consistently high suction power. The integrated cleaning mechanism periodically shakes the filter knocking the dust from the filter and extending the length of time between swapping filters. All the features from the regular CT extractors carry over to both the AC dust extractors with only one difference with the CT 36 AC having a smooth suction hose that is designed for the Planex drywall sander. The CT 48 AC comes standard with the traditional anti-static hose that is more designed for woodworking applications. Overall the CT 36 AC is best for drywall applications whereas the Festool CT 48 AC is the top-of-the-line and best-performing dust extractor that Festool offers.
Festool CTC Cordless Dust Extractors
Festool CTC SYS
The Festool CTC SYS is the newest cordless dust extractor designed for jobsite use in a compact form that is small enough to fit between sets of systainers. The CTC SYS is designed for a contractor working in a client's home with other cordless tools that need dust extraction but only a little bit here and there. One downside of the compact form is a decrease in CFM to only 85 whereas the CTC MIDI I is 109 CFM and the others over 130 CFM. Also, the capacity is limited to only 1.2 gallons so if you use it a lot you will be changing the collection bags often. The CTC SYS comes with cleaning accessories, an anti-static hose, a shoulder strap, onboard hose storage, and a Bluetooth remote control. If you're already invested in the Festool ecosystem this is the perfect dust extractor for maximum portability at construction sites or in your client's homes. I would not recommend this model for a DIY woodworker or small home shop.
Festool CTC MIDI I (Best Portable Dust Extractor)
The Festool CTC Midi I is the best portable dust extractor offered by Festool for numerous reasons. The CTC MIDI I is able to run off battery power and still produce 109 CFM of suction power making it perfect for larger Festool power tools. The CTC MIDI I also comes standard with Bluetooth capability and includes a remote control. The capacity is limited to only 3.96 gallons or 15 liters but is enough to handle most job sites while still having easy portability. Another feature that is unique to the MIDI models is the manual filter cleaning mechanism to quickly clean and extend the life of your filter while restoring suction power. The CTC MIDI I comes with cleaning accessories, an anti-static hose, a Bluetooth remote control, onboard hose storage, and systainer docking. In my opinion the CTC MIDI I is the best portable Festool cordless dust extractor with standard features similar to their larger models all in a portable footprint.
Festool CT-VA Pre-Separator (Best Dust Extractor Accessory)
The Festool CT-VA is a cyclone separator designed to minimize the overall cost of keeping your dust collector running. It's Festool's version of a Dust Deputy but in a form that can easily be docked on top of your extractor and used with other systainers. It uses a 3-step system to separate large debris and dust particles from entering your dust collector and increases the time between bag changes and saving you money. The Festool CT-VA Pre-Separator is designed for woodworkers who plan to use their dust extractor on a daily basis or in a business because it will eventually pay for itself with cost savings on replacement bags and filters.
Festool Dust Extractor Accessories
To get the most out of your dust extractor, there are a few accessories that you should really consider which is why I also created a list of the best Festool dust extractor accessories. The main accessory that is compatible with all the different models is the standard cleaning set that includes extension pipes, a curved handle, a suction brush, a crevice nozzle, and the floor nozzle. I personally use this set with my CT 36 and it makes cleaning up the shop and the sawdust around my tools really easy. Even though the set is expensive, I couldn't live without it. Another great accessory to consider to speed up your workflow is the Bluetooth remote control for the CT models. If you hate constantly going back to turn on the extractor manually this allows you to quickly hit a button from the end of the hose to turn it on remotely. If you primarily build very precise or high-dollar pieces of furniture you may want to consider the upgraded suction hose with integrated power cord and protective sleeve to protect the surface while you sand. Another great accessory that I highlighted above is the CT-VA Pre-Separator which can extend the length of your bags and minimize your operating cost. Most of the accessories you can live without but to me the standard cleaning set is a must-have.
Which Festool Dust Extractor Should You Choose?
Whichever Festool dust extractor you choose will be a great investment and you won't regret your purchase because they are absolutely worth the money. I personally love my CT 36 and it made such a big improvement in my shop that I wish I had gotten it sooner. The Festool dust extractor you should buy depends on a few important considerations like the size of your workshop and usage as well as if you need portability or a cordless option. Personally, I believe the CT 36 is the best Festool dust extractor overall with all the necessary features, the ability to upgrade to Bluetooth, and big enough for any application. However, if you need a dust extractor that is portable for jobsite work the CT MIDI or the CTC MIDI are the best options due to their size and features.
To sum things up here are my top picks based on specific needs:

Frequently Asked Questions
-
Festool's dust extractors are absolutely worth the money and make a big difference. I personally have the CT 36 and it has done a tremendous job capturing fine particles and helping to have clean air in the shop. I wrote extensively about my personal experience with my Festool sander and dust extractor combo and why I think it's a good idea to invest in them for your shop.
-
The size of the dust extractor you need depends primarily on how you plan to use it, but the larger the better. If you plan to use the dust extractor as your main dust collection system you need a huge container capacity so you're not replacing the filter bags as often. If you have a small shop and plan to use it with random orbit sanders or a Festool domino you can get away with saving money and buying a smaller unit.
-
The main differences between a dust extraction machine and a shop vac are the level of filtration and suction power. Typically a dust extractor will have HEPA filters and can filter out very fine dust and debris in contrast, a shop vac will blow out a lot of fine dust into the air and only capture larger particles. Shop vacs in my opinion should be used like vacuum cleaners and are not designed for fine wood dust whereas, a dust extractor is specifically designed to provide a safe woodworking environment and capture harmful fine dust particles.
