I change filters monthly and they are very easy to change. They fit my topfin filter and the only problem is getting them to fit the grooves properly, but that's not a problem for me. Changing the filter only takes about 3 minutes and my aquarium stays clean. I have an algae problem and it's not helping, so I'm rating it 4 stars.
