Product review (5 stars): No worries about carbon fines
Fit perfectly and water tastes great with no more chlorine flavor.

With regard to reviews complaining of black water, this is normal for charcoal filters which require a good flushing to remove the carbon fines. Some filters have more carbon fines than others and this filter took more flushing than some others that I've used. More importantly, the filter is performing perfectly after running a few gallons of water through it. Very satisfied.
