Just an update in case anyone is running into similar issues and it can help them. Stratasys wanted $250 for a replacement filter… Literally just that piece of plastic with some filter inside. I was determined to find an alternative and it took me a while but I think I found one. Basically I bought a syringe filter that I believe is typically used in the medical field (specifically the EMD MILLIPORE SLFG-050-10 FG) . It is a name brand one that’s 50mm diameter with 0.2um pore size. It does mention it is for “Vacuum Protection In-Line Filter with PTFE Membrane”. It seems legit and not any worse than the stock vacuum filter (about same area also). I paid ~$40 for a 10 pack. I have been using it for a couple weeks and haven’t had any issues yet.
