Cirfifth Foam Filters for Cat Water Fountain, 12 Pack, sponge

Black sponge-foam cat water fountain filters from Cirfifth give you twelve replacements in a single pack. Each one measures 10.9 by 6.6 by 7.6 cm and weighs 32 g, so the piece is small enough to sit in the filter slot of a fountain. The pack keeps a spare set on hand for the replacement routine, which the maker sets at every 2 to 4 weeks.

Twelve black filters in one count

The pack is a 12-count of filters in black, sold under model name Sponge-U. With twelve in the box, the change schedule of every 2 to 4 weeks can be followed twelve times before the pack runs out.

Will these filters fit your fountain?

Cirfifth lists these as compatible with multiple cat fountain and pet fountain models, so the number and brand of fountain on your counter is the first thing to check. Measure the filter slot of your fountain and compare it with the 10.9 by 6.6 by 7.6 cm footprint of one filter before ordering. A fountain that takes a different filter shape or size is not covered by the compatibility the maker states.

What reviewers say about fit and cleaning

Several reviewers mention how the filter fits and how it is sized, and a similar number comment on installation and cleaning. Two reviewers bring up build durability. These themes come from buyer feedback on the filters themselves, not on any particular fountain.

What the pack contains

• Twelve foam filters for a cat water fountain, in black
• Model Sponge-U, made of sponge and foam

Questions about these foam fountain filters

How long does one filter stay in the fountain?

The maker gives a replacement interval of every 2 to 4 weeks, so one filter covers that period before it is swapped for a new one.

What do I do with a new filter before fitting it?

Soak it in water for 2 minutes, then rinse it thoroughly under running water before it goes into the fountain.

How big is a single filter?

One filter measures 10.9 x 6.6 x 7.6 cm, or 4.3 x 2.6 x 3 in, and weighs 32 g (1.1 oz).

What material are the filters made of?

They are high-density sponge foam, listed as sponge and foam, and they come in black.

How the high-density foam works in the filter slot

The filters are cut from high-density sponge foam, which is the material the water passes through in the filter slot. Spare black filters in a 12-pack let you keep the replacement routine going without hunting for a single piece. The 2-minute soak and the rinse under running water are done before the filter is placed in the fountain, and the maker sets the swap at every 2 to 4 weeks.
