NestPurr™ Fountain Filters 6-Pack – for the Flow™ 3L Fountain

A dirty filter is the #1 reason cats abandon their fountain — and go back to not drinking.

Keep the fresh-water magic working

These are the official triple-layer replacement filters for your NestPurr Flow™ 3L fountain — the exact filter cotton and carbon sponge that slot into the fountain lid (pictured). Swap one in every 2–3 weeks and every sip stays as fresh as day one.

Why your cat notices the difference

• Traps hair, dust and food particles before they reach the pump — extends its life too
• Activated carbon removes odors that make cats snub their water
• Softens the water for a taste picky drinkers actually prefer

One pack, four months of fresh sips

6 filters = up to 4 months of clean water. At about C$3.30 a filter, it's the cheapest health habit your cat has.
