Product review (5 stars): Same as original filter and so easy to install
There are non GE knockoffs out there for much cheaper.  But honestly, you are replacing this every 6 months.  What's another $10-$15 for your peace of mind?  It is very likely those knockoffs provide the same filtration system, but I rather not risk my health on $15.  Having said that, this GE model is same as the original one that came with the fridge.  It's also very easy to install.
