24 Filter Cartridge and 12 Sponge Refills for Pet Water Fountains

These filters are made of BPA-free material, and contain activated carbon, which together with the non-woven fabric form a four layer circulating filtration system. This effectively filters pet hair, food residue, absorbs odours, and softens the water, providing your pet with fresh, healthy drinking water

The package contains 24 filter cartridges and 12 sponge refills

Suggestions for use: To keep the drinking water fresh and hygienic, it is recommended to replace the pet water fountain filters every 2-4 weeks, depending on the number of cats in your home. Before using the pet fountain filter replacement, rinse them thoroughly under running water and then install them in the cat fountain.
