Dog and Cat Water Fountain Filter, Set of 2

My old water dispenser broke after a long time, and the new one doesn't fit the filter, so I'd like to give these to someone who is currently using this filter. The listing says it's a 3-pack, but I used one, so there are two remaining.
Also, although they are unused, some time has passed since purchase. The shape is different from the current filters, so please check if it matches the filter you are using.

Pet fountain filter with a 3-layer filtration system to keep water clean.
- Filter Type: 3-Layer Filtration System
- Function: Keeps water fresh and clean
- Feature: Catches debris
- Compatibility: Suitable for all pet fountains

Thank you for looking.
