【Compatible Models】：These replacement filters fit the Pumpless Pet Water Elfin Fountain D1 / D1PRO / E1 / E1+. For other fountain models, please compare the shape and dimensions of your original filter to ensure compatibility. You may find matching replacement filters for other fountain styles within our store for purchase.
【Regular Filter Replacement】：We recommend replacing the filter and sponge every 1–2 weeks to sustain consistent high-efficiency filtration, delivering clean, fresh drinking water for your pet. This encourages increased water intake and lowers the risk of pet urinary tract infections (UTIs).
【Multi-Layer Filtration System】：This cat fountain filter is crafted from natural cotton fiber, activated carbon and ion exchange resin, and is completely BPA-free. Activated carbon purifies water and eliminates unpleasant odors, while ion exchange resin absorbs trace heavy metals and softens tap water.
【Easy Pre-Use Preparation】：Rinse the filter thoroughly under running clean water for 2 minutes before installation. This washes away loose excess activated carbon dust and activates full filtration performance, allowing the filter to reach optimal working efficiency quickly.
【Warm Reminder】：Filter dimensions: 3 x 3 x 0.3 inches. Be sure to fully rinse the cat water fountain filter with clean water prior to use to unlock its maximum water purification performance.
