Product review (5 stars): Pay a little more for safer water, not for water that just tastes better
Water delivery is a little slower with the GE filter than with the cheaper replacement filters I've used instead.  However, no other cheaper filters that I could find are certified to remove lead and mercury; neither are the cheaper filters certified to remove crypto cycts, which is equally important to me.  If your only intention is to have water that tastes a little better, the cheaper filters will do that but don't expect them to provide significantly safer water as the genuine GE model is certified to do.
