Temperature could be your problem. Your cold temperature could be causing the metal to shrink around the threading. Put a hair dryer on it to expand the parts. This problem usually happens when filters are put on real tight in the summer and then tried to be removed in the winter. Don’t forget to put the install dates on the new filters with a magic marker.
When removing filters it’s best to apply a wrench as close to the top where is meets the filter housing. You probably need to get a better wrench that can fit up there. Maybe apply a little heat to the filter with a torch as well.
