Fountain filter and pump finder

How do I find my fountain's filter code?

Start with the fountain itself. Most makers print a model name or number on the underside of the base or on the box. Catit, for example, sells several fountains that share the Flower name, and the filter you need depends on which one you own, so the exact name matters more than the colour or size.

If the label is worn off, use these in order:

1. The manual. Manufacturers host PDFs for most current models, and the brand pages linked below point to them where we have the address.
2. The order confirmation or packaging, which usually carries the model name.
3. The old filter. Part codes are often printed on the pack, and the finder searches them as well as model names.

Search the finder with whatever you have: a brand, part of a model name, or a code. The table beneath it works without JavaScript too, and every row shows the date we last checked the source.

Original or compatible filter?

An original filter is made by the fountain's own brand and listed for your model. A compatible filter is made by someone else and says it fits. Original parts are the safe default because the manufacturer's interval and cleaning advice are written around them.

Our rule in this database: a compatible filter appears only when its own maker states the fit for that model. We do not guess from shape or from what other buyers say worked. If you buy a third-party filter, check the product page names your model, and compare the media (carbon, resin, foam) with the original, since a filter without a pre-filter foam layer lets hair reach the pump sooner.

Why change intervals differ between brands

The numbers in the database are manufacturer claims and they do not agree. Catit states about 30 days for its triple action filter, PETLIBRO states two weeks, and PetSafe gives 2 to 4 weeks for carbon and 1 to 2 months for foam. Makers also add conditions: more pets, a dirty room or hard water mean sooner. Treat the stated number as a ceiling and change earlier if flow drops or the water smells. The replacement interval page has the full comparison and the warning signs.
