A+ addition to 360 fountain by sandi121 from South Carolina09/16/2014
the filter catches the food and hair before it gets into the motor and water. you do need to rinse it out and it can go in the dishwasher on the top shelf. it is better to change it out a new one when the filter starts to look frayed or well used. this is A+ addition to your 360 fountain.
