Fountain Filters
Replacement filters for popular cat fountains, compared on fit, pack size and change interval.
A filter only works in the fountain it's made for. Official filters fit exactly; third-party packs are cheaper but rely on the seller's fit statement, so match the fountain model carefully.
Change intervals range from about two weeks to a month. The calculator turns pack price and interval into a monthly cost.
What decides it
Fit
Match the exact fountain model; similar-looking filters often differ in size.
Interval
Follow the maker's schedule; hard water and several cats shorten it.
Official or third-party
Official filters fit exactly; third-party packs cost less.
Monthly cost
Compare cost per month, not per pack.
