Size: 17" x 11" Supplied in 3 grades coarse (black), medium (blue) and fine (green). The filters should be cut to size and placed in the filter so that the water runs through the black foam first, then the blue and finally the green. Filter foams should be replaced when the old foam has become lazy. ie. it doesn't spring open when folded over.
