Product review (5 stars): ... filter was 6 months overdue for a change as recommended by LG)
I didn't change my last filter on a timely basis (1 year old filter was 6 months overdue for a change as recommended by LG).  The water delivery system was down to a trickle when I finally installed a new one.  It was immediately back to full force.  I was amazed at the difference in pressure and will defineatley pay attention to switching this one out for a new one when the refrigerator tells me it is time to do so!!
