About this item

• DESIGNED FOR GULUNOOK YSJ402 — Specifically designed for the GULUNOOK YSJ402 4L Dog & Cat Water Fountain. Filter cartridge size: 3.14" × 1.77". Please check your fountain model and filter size before ordering.
• COMPLETE 8-PACK FILTER SET — Includes 8 filter cartridges, 8 pre-filter sponges, and 8 pump sponges. Filter cartridges measure 3.14" × 1.77"; pump sponges measure 1.37" × 0.98" for convenient replacement and routine fountain maintenance.
• HELPS REDUCE HAIR & DEBRIS — Filter cartridges help reduce hair, debris, and odors in fountain water. Pre-filter sponges help collect larger particles, while pump sponges help reduce debris buildup around the pump.
• UNPLUG BEFORE FILTER REPLACEMENT — Always disconnect the USB power before replacing filters or cleaning the fountain. Keeping the pump powered off during maintenance helps prevent air from entering the pump and interrupting water flow.
• PUMP NOT FLOWING? EASY RESET — If air enters the pump and water stops flowing, don't worry. Unplug and reconnect the USB power several times to help release trapped air and restore water flow. Add water until the pump is fully submerged.
