Review on BISSELL 3204E Featherweight Filter 8 Pack by Karen Perez

You may be surprised and a little annoyed at how quickly these filters clog. You don't replace them every time you empty your dust bin, but you do need an old toothbrush or something to brush away hair and dust. They get dirty quickly. You choose how long you want to wait before changing the filter, but eventually they get too dirty. I'm just glad they still fit and Bissell didn't reconfigure the dust box to make it obsolete.
