Keep your dog's fountain pristine with a 6-pack set of Kastty replacement filters. The kit includes activated carbon filters, mesh filters, and sponge filters, and each piece is individually sealed to preserve filtering quality during storage.
Quality details you can feel: the filters are food grade, and the PP cotton layer is durable, staying intact after days of underwater wear. The natural coconut shell activated carbon is tightly sealed inside, so no carbon particles should enter water.
This comprehensive set offers multiple filtration stages that help catch dust, hair, and other particles while supporting a cleaner tasting water. Water filtered with Kastty tends to feel fresher, which may encourage your dog to drink more willingly.
Perfect for homes with multiple pets, high-activity dogs, or fountains that see frequent use. The modular design makes replacement simple and quick, helping maintain steady hydration for your furry family.
Usage tips: rinse new filters thoroughly before first use and replace charcoal every 7-12 days, and sponge every 12-20 days, depending on pet activity. If you have more pets or lively drinkers, adjust accordingly for best results.
