Fresh water is the filter's job — swap it, don't scrub it.
These are the exact filters your MellowStream Fountain ships with — same size, same fit, no “close enough” guessing. A fresh filter every few weeks is what keeps the water clean, clear, and worth drinking.
✂️ Exact fit — made for the MellowStream, drops right in.
🧼 Catches hair & debris — so the pump stays strong and the water stays fresh.
🔁 Swap every 2–4 weeks — a 10-second change, no tools.
Which pack?
3-Pack — about 1–2 months of fresh water. Good first top-up.
6-Pack — 3–6 months covered. Our most popular — set it and forget it.
12-Pack — up to a year at the lowest per-filter price.
The honest part
Filters ship from our partner warehouse overseas, so they arrive in 7–14 days — a bit slower than the fountain itself. Order your next pack before the current filter is tired and you'll never notice the gap.
Common questions
Will these fit my fountain?
If it's the MellowStream Fountain from our store — yes, guaranteed. These are the same filters it ships with, from the same maker.
How do I know when to swap?
When the flow weakens or the filter looks discolored, it's time. For most homes that's every 2–4 weeks — sooner with multiple pets or heavy shedders.
