Product review (3 stars): since there are compatibles (good or bad, I don't know) for a fraction of the ...
Price for the filter is ridicules.  Fridge appears not to actually  measure the effectiveness of the filter when telling you to replace it.  Mine filter replacement warning came on exactly 6 months after the fridge was installed.  Duhh...what's so "E" about that.  I think GE is taking advantage of a captive audience, since there are compatibles (good or bad, I don't know) for a fraction of the cost when you buy an RPWF (non- E).  I think it is marketing, smoke and mirrors and take advantage of the consumer.
