We have a water fountain for our cats and needed just the sponge piece for extra filtration. We clean out the fountain once a week and replace the filter once a month, this is what works for us to prevent hair & debris build up and keeps the fountain operating in good condition. I highly recommend this product, it was slightly larger than the original filter but it was easy enough to squeeze the foam-like piece into the allotted space. Works great!
