Product review (5 stars): And actually tells me its dirty and time to change(as per refrigerator light)
Been using for a few years now, and they DO work very well.  Simple to change, and filters superb!  Once a year our water company flushes system and this filter stops sediment completely.  And actually tells me its dirty and time to change(as per refrigerator light).  Good price for three.  I highly recommend and will continue to use.
