About This

【30-Piece Value Set, Individually Sealed】 The kit includes 10 activated carbon filters, 10 pump sponges, and 10pre-filter sponges – 30 pieces total. Each piece is individually sealed to prevent moisture absorption and quality loss during long-term storage. Stock up with confidence and save compared to loose filter packs.
【Tool-Free Installation, Ready in Seconds】 Main filter size: 6.73" x 1.65", pump sponge: 1.37" x 1.14" – matches Kastty’s original slots perfectly. Simply rinse the filter under tap water for a few seconds to activate, then press into place. Replace the fountain water after each filter change for best results.
【Triple Filtration + Water Softening】 Activated carbon removes fishy smells and chlorine; ion exchange resin reduces calcium & magnesium to prevent limescale and soften water; non-woven fabric and sponge physically trap hair and food crumbs. Even if your dog plays in the bowl, the reservoir stays clean.
【Pump Sponge Included – Extends Motor Life】 The 10 small pump sponges fit directly over the pump intake, catching fine debris before it can jam the impeller. Replace every 12-20 days to keep the pump running smoothly and last 2-3 times longer than using only the main filter.
【Fits ONLY Kastty JSFS76D / JSFS78 / JSFS79 – No Guesswork】 This filter is custom-molded for these three fountain models . Check the model number on your fountain’s bottom label. A perfect seal ensures all water passes through the filter – no bypass or leakage
