Material: Cat fountain filter is made of cotton layer, activated carbon and ion exchange resin.
Purify water quality:Pet fountain filter can filter hair and residue, remove odor and foul smell from water and keep water fresh so that pets can drink clean and fresh water.
6 Pieces Pack:Our pet dog and cat fountain filters come in a box of 6 pieces, each piece in each group has its own packaging, individually wrapped and sealed to maintain high quality.
Replacement Frequency:We recommend replacing the pet dog and cat fountain filters in 2 weeks in summer and 2 to 4 weeks in winter to keep the water fresh.
Before use: To prevent the activated carbon powder (which will not harm your pet) from falling off into the water, soak the filter in water for 2 minutes and rinse thoroughly under running water before use.
