Pack of 9 replacement filters and pack of 18 filter sponges for 2L cordless automatic pet water fountains

Suitable Fountain: Replacement filter and sponge set, perfect for a 2L cordless automatic pet water fountain.

6-Layer Filtration System: Eco-friendly polypropylene shell traps hair and large particles; ion-exchange resin filters heavy metals and improves taste; activated carbon removes chlorine and odors, purifying and refreshing the water; high-density cotton traps hair and debris, keeps the water clean, and reduces the risk of urinary tract infections.

Replacement Filter Sponge: High-density replacement filter sponge captures more hair and debris, preventing them from entering the water pump and extending the life of your fountain pump.

Regular Replacement: We suggest replacing the water filter and sponge every 3-4 weeks to properly maintain your pet fountain.

Please change it more often if you have multiple pets. Tips: Before replacing the filter, soak it in clean water for 15-20 minutes, then rinse it thoroughly under running water. Keep the water clean and fresh.
