Pack of 12 activated carbon filters and sponges for 9.5L dog water fountain (6 filters + pack of 6)

Triple Filtration: The filter is made of non-woven fabric and coconut activated carbon; the activated carbon eliminates odors, and the non-woven fabric filters out hair and debris. The pump filter is a high-density sponge that prevents hair from entering the water pump, avoiding clogging. Provides Clean Water: Made of safe and odorless materials, this large dog filter transforms tap water into pure drinking water for pets; it protects the health of your pet's drinking water by providing high-quality water. Usage Steps: The dog water filter and sponge must be thoroughly soaked before placing them in the water dispenser. Please soak the filter in other clean bowls for at least 5 minutes. Regular Replacement: The carbon water filters should be replaced every 12 days; in warm weather, to prevent mosquito breeding, please replace them weekly; the pre-filter sponge should be replaced monthly.
