Product review (1 stars): Horrible!
This is a very late review as I forgot about reviewing this. This filter spewed out charcoal, I assume it was charcoal, for nearly the entirety of it being in the fridge. It worked great for about a week, then the smell came. At first I thought it was food in the fridge. So, I cleaned it out, dumped the ice from the icemaker tray, scrubbed everything down with water and bleach and washed it again with dishsoap. Still a horrendous smell. We put up with it for a couple weeks before I finally went down to Lowe's and bought a GE filter as there were none on Amazon with my prime shipping. After I pulled the filter out, I put it to my nose and it smelled like mold and something rotting in it.

It was sealed. So, I don't know what it could have been. The GE brand has never had this issue. It's more expensive for the GE brand, but well worth it as it doesn't smell rancid after 2 weeks.

I may have just received the oddball, but I'm sticking with GE.
