Custom sized filter paper?

Does anyone know of a supplier that does custom sized filter paper? Looking for 104mm that fits perfectly in the amp sintered set ups

You are probably going to be stuck making them, are you guys using tampontek lol? if not hmu on ig and ill shoot you some pics on how i do mine.

If Hayes filter is still around they used to claim they have a die to cut any size you need. Idk if there’s an moq, probably will be if they have to make a die. If not printing shops have die cutters and presses for box making. If you’re convincing enough I’m sure you’d be able to get a printer shop to die cut a few thousand sheets if you supplied a roll of filter paper to cut. (Lots of work, sorry)

Somehow missed this one! Yes we are still around and yes we can die cut custom sizes for you. Thank you, Greg
