Product review (3 stars): It is beautifully packaged and looks exactly the same as the GE ...
I bought this as a replacement filter for a future date, but I am giving it a 5 star review because it was less than 1/2 the price of the GE filters that I have been using.  It is beautifully packaged and looks exactly the same as the GE filters.  It was delivered quickly, and I received a very nice email from the seller stating that they were anxious to please and would stand behind their product.  I'll be using it in about 5 months when the GE filter that I currently have in use will become ineffective.  I don't expect that I'll have any problem with it.
3-23-2016  A couple of days ago I tried to replace the used GE MWF filter with this filter, but it did not work.  I was able to install it, but no water came through.  I don't know why, but luckily I had bought another filter at the same time as I bought this one, so I discarded this filter and used the other which works great so far.  I'll buy more of the one that worked.  I just changed this review from 5 stars to 3, based on the fact that it didn't work.  I didn't contact the seller.  The filter that I am using now was even cheaper than this filter.
