Cirfifth 12 Pack Cat Water Fountain Filters with Triple-Layer Filtration

A three-layer filter combines cotton, activated carbon, and ion-exchange resin to help catch hair and particles while improving water taste. The Cirfifth 12 Pack is made for an 84oz/2.5L round cat fountain, so matching the fountain type matters before you buy.

Each filter is individually sealed, and the pack includes 12 replacement filters. That gives cat owners a supply for routine changes without needing to buy filters one at a time.

What matters most

These replacement filters use a cotton layer, activated carbon, and ion-exchange resin. The listed benefits include filtering hair, particles, and heavy metals and improving the water’s taste. That makes them relevant for a household using a compatible fountain to keep water circulating for a cat, though the filtration description does not establish a particular level of contaminant removal.

Fit is the key buying detail: these are specified for the 84oz/2.5L round cat fountain shown in the product listing and are not compatible with Catit fountains. They are not universal replacements, so choosing by pack size alone could lead to a mismatch. Compared with buying a basic filter without listed filtration layers, this option identifies its three-part design, a filter made specifically for a different fountain is the better route when the shape or model does not match.

A solid pick if your fountain is the stated round 84oz/2.5L type and you want individually sealed replacements in a 12-count pack.

Cleaning & care

Before installing a filter, soak it in water for 2 minutes and rinse it thoroughly under running water, as the product instructions recommend. The suggested replacement interval is every 2–4 weeks. The actual schedule depends on following that guidance and the way the fountain is used, the listing does not specify a different interval for particular household or pet conditions.

For a practical routine, keep an unused sealed filter on hand, rinse the next one before a scheduled change, and install it in the compatible fountain. That follows the stated preparation steps without assuming that rinsing removes every possible residue or substitutes for cleaning the fountain itself.

Who it’s for

These filters suit cat owners who already have the specified round 84oz/2.5L fountain and want a multi-filter replacement pack. The individually sealed packaging can also help keep unused filters separate until they are needed. The listed filter material is non-woven fabric, and the stated dimensions are 5"D x 5"W x 0.3"H, useful details to compare with the filter currently used in the fountain.

Better avoided if you have a Catit fountain or another fountain whose filter format is not confirmed as compatible. The product information specifically excludes Catit and does not establish compatibility with other fountain brands or models.

Practical questions

Can these filters be used in a Catit fountain? No. The listing says they are not compatible with Catit fountains.

What should I do before installing one? Soak the filter in water for 2 minutes, then rinse it thoroughly under running water.

How often should the filter be changed? The recommendation is every 2–4 weeks.

Final verdict

The Cirfifth 12 Pack is worth considering when you need replacements for the specified 84oz/2.5L round fountain and value a clearly described three-layer filter with individual packaging. Its usefulness depends on an exact fit, the stated compatibility does not cover Catit fountains or confirm a universal design. Match the fountain first, then use the recommended soaking, rinsing, and replacement routine.
