Product review (2 stars): Not the real deal...
My first warning should have been that they were packaged in a plain bag with no branding.  BUT, I figured I'd give them a shot.  These filters fit....when dry.  Once they get wet, they compress, so there's a decent gap at the top of the filter.  The real deal filters have a mesh that gives it support...not these guys.  I seriously doubt they are real ReliON filters, but I can't prove that.  You've been warned, folks.  Won't be buying these again.
