We change the filters in ours about every two to three weeks.

They give you recommendations on the package, but you can rinse it off about two times before you put a new one in there and stick it back in, so I only replace mine about every three weeks or so. A lot depends on how clean you keep your fountain too. The cleaner you keep your fountain, the less often you will have to change the filters.

I change it when it starts to look slimy, maybe every 4 months... They are really expensive, so I try to make them last as long as possible. When I clean the fountain, once every two weeks, I also rinse the filter.
