Hook a Festool sander to a Festool extractor and you catch most of the dust at the tool. Most, not all — and the part that gets away is the part that matters.
We get at least 90% over the whole line of tools. We’re known for it — and we want to capture that other 10%.

That last 10% is the fine stuff, under a micron, and it does not settle politely when you pack up. Festool reckons it can stay airborne in a shop for hours. It is also the fraction no hose can reach, because some work has nowhere to attach one — hand sanding, planing, sweeping up.
The SYS-AIR is Festool’s answer, and the interesting part is its shape. It is a Systainer³ M 437 that happens to clean air — 22 lbs, two speeds, a cheap pre-filter in front of a pleated main filter, and a light that tells you when the pre-filter has had enough.
Being an M 437 is not a packaging detail. It means the air cleaner goes into the stack rather than beside it, at whatever height puts it nearest the dust: on the floor behind a mitre saw, at bench height next to an MFT, on a SYS-RB Cart if the job moves around. It carries Systainers, and Systainers carry it.
It’s really innovative that they put an air cleaner in a Systainer. This is a Systainer which is capable of carrying Systainers on top and on the bottom, so you can take this out to the job site and set it beside you.

Where it can’t sit next to the work, the 200 mm hose reaches instead — useful on stairs and in the sort of confined space that has nowhere to put a machine.
The reason to care isn’t tidiness. It’s the thing that creeps up on you over years in a shop:
I have some bad health issues with my throat. I did some metering in my shop, and basically I’ve got a really bad working environment for my lungs. After a long day of woodworking I have a really sore throat, even though I work with a mask on.

Two minutes of Festool showing where it actually goes on a job:
It also mounts overhead, which keeps the floor clear and puts it above the work rather than beside it.
For a hands-on take, Concord Carpenter ran it against a cabinet full of drywall dust at the JLC show.
One system. For everything. For everyone.
