Features

✅ WIDE COMPATIBLE ROUND REPLACEMENT FILTERS Outer diameter:5 inches, inner diameter:1.5 inches. Fits most standard round pet flower‑style water fountains. Please double‑check your original filter dimension before purchase to guarantee proper fit for smooth replacement.

✅ DUAL‑ACTION PURIFICATION FOR PET HEALTH Built‑in premium activated carbon plus ion‑exchange resin work together. Ion‑exchange resin softens tap water and helps lower urinary stone risks for cats and dogs. Activated carbon absorbs chlorine, strange tastes and bad odors to deliver fresh‑tasting drinking water for your pets.

✅ EFFECTIVE 3‑STAGE LAYERED FILTRATION SYSTEM Outer non‑woven cotton layer first catches pet hair, floating debris and dust to protect the fountain pump. Combined with resin and carbon inner layers, it greatly improves water clarity, reduces impurities and encourages your furry pets to drink more water daily.

✅ VALUE 4/8‑PACK BULK SUPPLY This value set contains 4/8 pieces replacement filters. With recommended replacement every 2‑4 weeks, it provides up to one‑year supply. Less frequent re‑ordering, always keep clean purified water available for your cats and dogs. Perfect for multi‑pet households.

✅ EASY PREP & INSTALLATION Simply soak each new filter in clean water for 2 minutes and rinse under running tap water before installation. This removes loose fine dust and activates carbon material, giving crystal‑clear water right from first use. Quick swap for daily pet fountain maintenance.
