My English bulldog sheds like crazy so I let my Roomba 675 run almost every day. I often change the filters in them, so I was glad when I found these replacement filters. Buying replacement filters directly from iRobot was much more expensive. I was disappointed because on most of these filters the adhesive holding the foam to the edges of the filter is exposed which causes the filters to stick together in the box. The filters fit the Roomba 675 snugly, but the exposed edges of the adhesive will cause the filter to stick to the grooves in the dust bin. This makes it difficult to remove the filters.
