Description
The consumable part. Filters need changing every few weeks — leave them too long and the fountain starts working against you, pushing trapped debris back into the bowl.
Key features
- Fits AIWO fountains — the matching replacement part.
- Two pack sizes — 3 pieces or 3+3.
- Keeps water clear — traps fur, grit and food debris.
How often
Replace every 2–4 weeks, sooner in a multi-cat household or with a long-haired cat.
