Product review (5 stars): Good Item
Great filters.  They last a while.  My only gripe is having to pour out and waste a gallon or more of water when you initially install them.  That seems like it should be unnecessary.  Hopefully they improve this factor in the future.

Also, it would be nice if there were some place or way to recycle these things.  The filters are quite large, maybe 12 or more inches, and it seems like a waste to just throw them in the trash.

But as far as filtering my water, they last a while and give good tasting H20, so I can't complain about that.  And Amazon sells them cheaper than anybody else, so this is THE place to buy them.
