Product review (5 stars): LONG LASTING
THESE FILTERS HAVE LASTED ME OVER A YEAR AND WITH A FAMILY OF 7 WITH FRIENDS AND FAMILY OVER A LOT WITH CONSTANT USE YOU WOULD THINK I WOULD BE REPLACING FILTERS LEFT AND RIGHT BUT THESE LAST AND WITHIN A YEAR I HAVE ONLY USED 2. I WILL ORDER THESE AGAIN WHEN NEEDED.
