Product review (5 stars): Fits and works perfect
Update 8/9/2015: I continue buying these, and still am completely satisfied and confident with them. Just placed another order for 2 more.

Update 7/13/2013: I purchased and installed my second filter cartridge of this model, and it works fine too, no fully tastes at all. I have not noticed any leaks like some others have posted here in their reviews.

I have nothing bad to say about this filter. It fits, and after following the 15 minute soak in water and purging it as per the instructions, the water tastes fine, same as the genuine, much more expensive LG filters. My water supply is not that bad anyway, so maybe I should just say it does not ADD any bad taste to the water. We just have to trust that the certification of these filters, any of them, is accurate as to what they remove from the water.
