Product review (4 stars): Was it a good deal after all???
I was very pleased to find a three pack of my needed filters... I like to be able to replace them as needed by having them on hand.  But to my dismay, one seemed to be defective.  So was it such a good deal after all?  How do you go about sending ONE item out of three pack back???  especially when it has already filled with water???  So I tossed it and went on to the next filter - which is working perfectly.
