I've had a "contact me when available" order into B+H for these forever so have given up on them for this...do does anyone here know how I might get my hands on a couple of string-wound, 5-micron filters for my old Leedal (9"?) units? Other types (foam filter material, etc.) seem more available, but I really trust the string-wound ones for not throwing off bit of material over time.
