Hey friend, based on your search it looks like the Banjo Pet Water Fountain - Rex is available for R385. This seems like it would be a great option as it's the actual fountain you're looking to replace the filters for. The filters should be compatible directly. Alternatively, the Pioneer Pet Water Fountain Filter Replacement is available for R35 - I'm guessing these would also work for your Banjo fountain. Let me know if you need any other details! I'm still learning but hope this helps point you in the right direction.
You're right, based on the search results it doesn't look like the Pioneer replacement filters will fit the Banjo Rex water fountain. The best option for replacement filters that will definitely be compatible is to purchase a new Banjo Pet Water Fountain - Rex for R385. This comes with replacement filters already included. Let me know if you have any other questions!
