About This

【Compatibility First】Designed for the MISFANS 4L ceramic dog water fountain in white or black. The main filter measures 3.6 x 2.5 in, the round pre-filter measures 2.1 in, and the pump sponge measures 1.3 x 0.9 in. Compare your existing parts before ordering; fit with other brands is not guaranteed.
【Complete 36-Piece Replacement Set】Includes 12 multilayer main filters, 12 round blue pre-filter sponges, and 12 rectangular pump sponges—one matching set for each scheduled change. This pet water fountain maintenance pack is planned as an approximately 3-4 month supply; actual use varies.
【Multilayer Filtration for Circulating Water】Nonwoven layers help catch hair and visible debris, activated carbon helps reduce everyday odors and unwanted taste, and ion-exchange resin supports routine water conditioning. Separate pre-filter and pump sponges add protection against larger particles.
【Prepare Before First Use】Soak each main dog water fountain filter in clean water for 3 minutes, then rinse for 30 seconds to remove loose carbon dust. Install the main filter, blue pre-filter, and pump sponge in their matching positions before restarting the fountain.
【Replace Every 1-2 Weeks】For consistent filtration, replace the main filter every 1-2 weeks and more often in hot weather or multi-pet homes. Rinse the dog drinking fountain parts and clean the pump during each service; replacement timing varies with water quality and daily use.
