I'm using this as well. Just checked it for the first time in the ~4 months I've had it, and it was mostly clean, but surprisingly had caught some rather large bits of hair and fluff.
Hard to say if they have been sucked up into the Mac Studio without the Spiegen filter, but if nothing else it's easier to clean and provides another layer of protection.
