Cat & Dog Water Fountain Replacement Filters – Square Activated Carbon Filter for Veken & 2.5L Pet Fountains (4/8/16 Pack)

PurePetFlow Activated Carbon Replacement Filters are designed for square pet water fountains to help provide cleaner, better-tasting water for cats and dogs. Each filter features a triple-layer filtration system with a polyester pad to capture hair and debris, activated carbon to reduce chlorine, odors, and unpleasant taste, and ion exchange resin to help reduce heavy metals and soften water. These replacement filters are compatible with Veken, Wonder Creature, Comsmart, and other square-style 2.5L / 84oz pet fountains. Filter size is 125 mm (4.92 in) with an inside diameter of 33 mm (1.3 in); customers are advised to measure their fountain before purchase to ensure proper fit. For best performance, soak the filter in clean water for 2 minutes before use, rinse thoroughly, and replace every 2–4 weeks depending on usage and number of pets. Suitable for use with both cats and dogs.
