Product review (5 stars): It's a deal.
GE wanted $55 for this filter.  I think Amazon offered it at $18.  The only difference is the GE unit had a chip to remind the consumer when to change it out.  If you like to spend wisely, stretch your dollars, and avoid the obscene pricing of the manufacturer, keep GE out of the picture.  The original equipment manufacturers prey off the unsuspecting.  The 'offbrand' does the job and provides a nice respite from predatory manufacturering pricing.
