Product review (5 stars): Original Frigidaire water filter that is easy to install
This works in my Frigidaire Model J51-23, so what's not to love. It is exactly the same filter as the one that came with the fridge. Also, it was easy to install.  I removed my old one by pressing in and then pulling out. To install this one, I removed the cover on the prongs and then lined the ridge line up with the receptacle and pushed it in place.
