I just got a chance to measure them accurately, sorry I haven't had a chance to get the Vita part number yet.
Dia 5 11/16" X 6 1/8" long, just the length of the filter body not including the 1 1/2" fine thread stub or the crescent shaped handle on top. I haven't been able to cross reference to any other filter. I can't believe this is a proprietary filter exclusive to Vita.
thanks,
