The Catit Fresh & Clear Replacement Foam/Carbon Filter is for use with the Catit Fresh & Clear Drinking Fountain for Cats. This dual-function replaceable filter helps to collect debris, food and sediment, as well as helping to reduce bad tastes, odors and absorbing impurities present in tap water.
The filter should be replaced every 3 weeks or when the filter becomes visibly saturated with foreign matter (debris, food, hair, etc). More frequent changes may be necessary due to indoor environmental and water conditions, as well as multiple pet use.
These filters fit Catit Fountain models 50053 AND 55600 ONLY
