Stock Up Longer. Reorder Less. Keep Fresh Water Flowing.

Keep your DeftPet pet water fountain ready for everyday use with a long-term replacement set of 12 multi-stage fountain filters and 12 pre-filter pump sponges.

Each main filter combines activated carbon, ion exchange resin and non-woven filtration material to help capture pet hair and fine particles while helping reduce unwanted tastes and odors as water circulates through the fountain. The included pre-filter sponges help intercept larger hair and debris before they reach the pump intake.

With 12 individually sealed replacement filters, this value pack is designed for pet parents who want to keep filters on hand and reduce frequent reordering. When replaced approximately every 1–3 weeks, the set provides roughly 3–9 months of routine filtration, depending on household conditions and usage.
