Filter in Bathroom Fan

I removed the cover to our bathroom ventilation fans and was suprised to see that they do not vent outside as I had assumed but only recirculate through a charcoal filter. The filter is supposed to be changed every year (currently 11 years old and counting).

I have checked Home Depot and Lowes and can't find a filter small enough (7"*4") and the filters I do find are fairly expensive. Every new fan that I see vents out. I have not seen any new fans that recirculate like ours do.

Does anybody else have fans like this? Does anyone know a source for filters? I am thinking about just buying and installing new fans that vent.

Quite frankly, an bathroom fan that does not vent the air to the outside is a waste of money and will not adequately remove moisture from the room. You will be ahead of the game if you remove this filtered air fan and replace it with one that exhausts the air.
