Key Features
Maintains SuctionThe self-cleaning fleece helps prevent fine dust from caking inside the bag, so your dust extractor holds suction longer instead of fading off before the bag is full. Built for CT MIDIThis Festool filter bag is made for compatible CT MIDI dust extractors, giving you a proper fit and cleaner dust collection without improvising with generic bags. Cleaner DisposalThe tear-resistant fleece and integrated closure help keep debris contained when it is time to swap bags, which means less mess back in the shop or on the job.
Overview
The Festool 498411 Self Clean Filter Bag for CT MIDI (5pk) is a replacement dust extractor filter bag made for compatible Festool CT MIDI dust extractors. This is a filter bag designed for dust extraction. Model Number: 498411. If you are collecting fine dust and want to keep suction more consistent as the bag fills, this is the upgrade that matters more than most users realize.
What makes this bag different is the self-cleaning fleece material. Fine dust usually sticks to the inside of a standard bag and starts to cake up, which chokes airflow and makes the extractor feel weaker long before the bag is actually full. Festool built this bag to flex instead of turning into a rigid dust shell, so the bag can keep working efficiently deeper into the fill cycle. That means better extraction performance and better use of the bag you paid for.
This bag also works as a pre-filter, trapping particles down to 5 microns along with larger chips and debris. In real use, that matters because it helps reduce the amount of fine dust reaching the main filter. Less dust loading on the main filter can mean less wear, less frequent filter replacement, and more consistent extractor performance over time, especially in sanding, finish work, and other fine-dust applications.
Festool also handled the practical side well. The material is tear resistant to help avoid bag blowouts, and the integrated closure helps seal the opening during disposal. That is a small feature until you have to change a bag full of drywall dust, sawdust, or fine sanding debris in the back of a van or inside a finished space. Then it becomes one of the main reasons to buy the right bag instead of a cheaper substitute.
Compatibility is the key buying point here. Product data identifies this bag for Festool CT MIDI dust extractors, and Festool also notes suitability for CTL MIDI units manufactured until 2018. If you are replacing bags on one of those extractors, this is the bag you want to match the machine correctly rather than trying to adapt a universal option that may not seal or load properly.
This is a smart buy for woodworkers, remodelers, painters, drywall contractors, and anyone running a Festool dust extractor for cleanup or tool-triggered extraction. It is especially useful for users collecting fine dust where airflow drop-off shows up quickly with ordinary bags. If your extractor is part of your sanding, cutting, or cleanup routine, the Festool 498411 Self Clean Filter Bag for CT MIDI (5pk) helps protect suction, keeps disposal cleaner, and gets more usable life out of every bag.

Pro Tip
If you mainly collect fine sanding or drywall dust, change the bag based on suction feel, not just how full it looks. The whole point of the self-cleaning fleece is better airflow deeper into the fill cycle, but once performance finally drops, swap it before the extractor starts working harder than it needs to.
