6 Best Festool Dust Extractors for 2026

The Festool CT 48 EI AC HEPA is a powerhouse engineered for professionals who demand uninterrupted suction and intelligent automation on large-scale jobsites. With its AUTOCLEAN system, this extractor maintains peak performance by automatically cleaning the main filter at user-defined intervals—15 to 120 seconds—ensuring that even in the dustiest environments, airflow never plummets. The integrated automatic outlet module is a game-changer: plug in your corded Festool, and both the tool and extractor fire up in sync, eliminating missed dust capture during startup.

In real-world use, the 577876 CT 48 shines across demolition, flooring, and cabinet installation tasks, where continuous operation is non-negotiable. Its 5-level suction control lets you dial in just enough power for fine sanding or max it out for aggressive grinding, while the Bluetooth-enabled smart start works flawlessly with compatible battery tools and remotes. At 16 gallons (60L), the tank capacity drastically reduces emptying frequency, though the unit’s size makes it less ideal for tight spaces or solo climbs up staircases. It handles drywall dust like a champ, but wet pickup is not supported—stick to dry applications only.

Compared to the CT 36 EI AC, the CT 48 offers greater volume and runtime per dump, making it the superior choice for crews tackling multi-day projects. While it shares core features like touch controls and app-based filter cleaning, the larger footprint and higher weight position it as a stationary workhorse rather than a mobile sidekick. It outclasses mid-size models in endurance and suction consistency, though it commands more space and requires a dedicated circuit. For contractors prioritizing automated efficiency and heavy-duty performance, the CT 48 EI AC delivers where it counts—especially when paired with a full Festool ecosystem.

Meet the Festool CT MIDI I HEPA, a precision-balanced mid-tier extractor that brings high-end smarts to a lighter, more agile frame—perfect for tradespeople who move fast and work clean. Boasting 130 CFM of suction and a 3.9-gallon (15L) container, it strikes a rare balance between portability and power, tackling everything from trim sanding to tile cutting without bogging down. Its standout feature? Bluetooth auto-start that syncs with Festool’s battery tools, so the moment you pull the trigger on a TRION sander or BOHLER drill, the extractor kicks on—no foot taps or manual switches.

On the job, this model proves its worth in confined areas like closets, bathrooms, or vehicles, where larger units are cumbersome.

The five-level suction adjustment lets pros fine-tune performance—saving energy on light tasks while unleashing full power for heavy debris—while the automatic outlet module syncs flawlessly with corded tools, eliminating startup lag.

In field testing, the CT 36 holds its own on expansive flooring or framing jobs, running for hours without filter clogging thanks to its advanced self-cleaning cycle. Its 36-liter capacity strikes a smart compromise between frequent emptying and portability, making it easier to haul up ladders or move between floors than the 60L CT 48. The touch controls are responsive and glove-friendly, and Bluetooth integration allows remote activation via compatible tools or the optional remote. However, its lack of Sys-Dock compatibility means you can’t attach a power tool carrier, a notable omission compared to the CT MIDI I.

Against the CT 48, the CT 36 trades tank size for mobility, making it ideal for solo contractors or small crews who need automation without the heft. It outperforms the CT 15 in suction consistency and filtration longevity, but doesn’t offer cordless capability like the CTC MIDI I. For those who want smart filtration, heavy-duty build, and real-world adaptability on large sites, the CT 36 delivers premium features in a more manageable form. It’s the ultimate middle ground between power and practicality—especially when jobs demand both brains and brawn.

The Festool CT 15 is a compact titan of portability, designed for the craftsman who values clean floors and faster setup without lugging around a full-size extractor. Despite its 3.96-gallon (15L) tank, it’s one of the most agile units in the lineup, tipping the scales at just under 20 lbs—ideal for overhead work, stair climbing, or van-based daily drives. The AutoClean system keeps suction strong with periodic filter shakes, while the flat-top design doubles as a worksurface, letting you stack tools or materials on top without fear of tipping.

In practice, the CT 15 excels in tight residential jobs—think cabinet installations, baseboard sanding, or HVAC duct cleaning—where space is tight and mobility is king. Its high-efficiency turbine delivers impressive suction for its size, and the included crevice and upholstery nozzles mean you’re ready for detail work right out of the box. The Bluetooth auto-start works reliably with Festool’s cordless tools, though sustained heavy dust loads can overwhelm the smaller filter, requiring more frequent manual cleaning. It’s not meant for all-day drywall grinding, but for precision tasks, it’s spot-on.

Compared to the CT MIDI I, the CT 15 is slightly more compact and easier to carry, but offers less airflow and no Sys-Dock integration. It lacks the raw power of the CT 36, but makes up for it with nimbleness and smart storage. For finish carpenters, electricians, or HVAC techs who need a dedicated, go-everywhere dust solution, the CT 15 is unmatched. It doesn’t outperform larger models, but for quick, clean jobs where every pound counts, it’s the lightweight champion—offering full Festool intelligence in a pint-sized package.

The Festool CT MIDI I (non-Bluetooth) is a no-frills workhorse that brings core Festool durability and HEPA filtration to users who prefer simplicity over smart features. It skips the Bluetooth and app connectivity, but retains touch controls and a manual filter cleaning function, allowing you to maintain suction with a quick tap when dust builds up. With a 15L container and robust steel-axle chassis, it’s built to survive drop zones and daily wear, making it a favorite among framers and renovation crews who prioritize toughness over tech.

In real-world use, this model thrives in high-debris environments—tear-outs, framing, or demolition—where dust is coarse and conditions are rough. The tool-free filter changes mean less downtime, and the compact footprint lets it squeeze into vans or corner spaces effortlessly. While it lacks the AUTOCLEAN system of the EI models, the manual clean button is effective for resetting airflow between tasks. However, without smart start, you’ll need to power it on manually or use a separate switch—less convenient when both hands are on a tool.

When compared to the Bluetooth-equipped CT MIDI I (B07R9PYC9T), this version trades automation for reliability and cost-efficiency, appealing to users who don’t need remote start or app control. It’s heavier than the CT 15 but more durable, and while less advanced than the CT 36, it’s easier to move and maintain. For contractors who want Festool build quality without the bells and whistles, this model delivers. It’s the tough, straightforward choice—perfect for those who’d rather focus on the job than the app.

Step into the future of dust extraction with the Festool CTC MIDI I HEPA-Plus, the only truly cordless extractor in the lineup that delivers corded-level power without the tether. Running on dual 18V battery packs (36V total), its turbine generates suction strong enough to keep pace with corded models during sanding, cutting, and drilling—making it a revolutionary pick for remote or unfinished sites where outlets are scarce. At under 30 lbs, it’s easy to carry up ladders or across rooftops, and the three suction levels let you conserve battery when full power isn’t needed.

In the field, this model proves indispensable during off-grid installations, attic work, or vehicle detailing, where dragging extension cords isn’t feasible. The Bluetooth auto-start syncs perfectly with Festool’s Cordless 36V tools, so your extractor fires up the moment you do—no extra steps. The HEPA-Plus filtration captures 99.97% of particles down to 0.3 microns, ensuring clean air even in confined spaces.
