Product Information

About

For Single-Pet Households — Designed for cat and dog owners with 71oz/2.1L capsule-style water fountains who want hassle-free maintenance without frequent reordering. Ideal for pet parents who prioritize consistent water quality and want to keep their fountain running smoothly.
Replace Every 2-4 Weeks — Swap out filters every 2-4 weeks based on pet count and local water hardness. Replace immediately if you notice reduced water flow, unusual tastes, or during your monthly fountain deep clean. Rinse pre-filter sponges weekly and replace with each filter change.
Prevents Clogging & Odors — Stops hair and debris from clogging the pump, which causes noise and reduced water flow. The triple-layer filtration helps reduce chlorine, odors, and mineral buildup that can make your pet avoid drinking from the fountain.
Precision Fit vs. Generic Filters — Engineered specifically for 71oz/2.1L capsule fountains with exact dimensions that prevent water bypass. Includes pre-filter sponges to extend pump life — something many standard filter packs leave out. Made with food-grade, BPA-free materials.
Dual-Stage Defense System — Pre-filter sponge traps hair and large particles before they reach the pump. The triple-action carbon filter then processes water through non-woven fabric (particle capture), activated carbon (odor and chlorine reduction), and ion exchange resin (mineral reduction) layers.
