Product review (4 stars): Excellent and verisitile kitchen water filter
This is a great idea, I really like the uniqueness of being able to use the filter in various types of containers.  It's easiest to think of it as a funnel, if you can use a funnel to fill it, you can use this filter to fill it.  The pitcher and filter fit perfectly together, and are easily separated so you don't have to try and pour with the filter in the pitcher.  The pitcher is basic and attractive.

The filter flows very quickly for a water filter.  This isn't the type of filter you want to take camping and filter lake water to drink, I'm not sure of its exact filtration capabilities.  This does an adequate job of filtering most of the nasty taste from my tap water, much better than the installed filter that supplies water from my refrigerator door.  I do find that filtering the "filtered" water from my fridge door thorough this filter, makes for an outstanding tasting water, significantly better tasting than filtering straight tap water.

Depending on use, replacing the filter insert every 2 months is negligible, maybe more often with a lot of use.  Replacement filters are about $7.50 each if bought in a 4 pack at the time I right this review ($30 for the pack).
