Product review (2 stars): Less activated charcoal = poorer filtering.
Didn't get the plastic taste from the cpvc pipes in our new house out like the GE filter did. It is only partly filled with activated charcoal, it weighs noticeably less than the GE filter (<a data-hook="product-link-linked" class="a-link-normal" href="/General-Electric-MWF-Refrigerator-Water-Filter/dp/B000AST3AK/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">General Electric MWF Refrigerator Water Filter</a>&nbsp;the filler material rattles around when you shake it (unlike the stock filter), and the water flows much faster. My wife can't taste the difference, but I can. It tastes better than the tap water, but I could still taste the plastic, even in my coffee. I couldn't taste the plastic at all with the GE stock filter. I hate to play three times more for the stock filter, so I'll have to experiment with some of the other alternatives.
