Keep your cat's fountain feeling cleaner and fresher through routine maintenance. Triple-layer replacement components trap hair and residue while activated carbon addresses unwanted odors and stains.
Triple filtration helps remove hair, impurities, odors, and stains from pet fountain water.
- Hair and visible debris in drinking water
- Unpleasant water odors
- Water impurities and sediment
- Dirty or clogged fountain filters
Make Every Refill Feel Fresh
Hair, debris, odors, and sediment can turn clean fountain water into a daily worry. Replace the filter components routinely and give your cat a cleaner-feeling drinking station.
Three Layers, One Cleaner Setup

Catch More Debris
The white fibrous pad traps hair residue and visible particles before they continue through the fountain.

Target Odors
The activated carbon center keeps fountain water fresher and reduces unwanted odors and stains as part of the layered filter system.

Pre-Filter The Flow
The porous black foam ring adds another filtration stage and supports a complete replacement assembly.
Keep Spares Ready
Eight white pads and eight black foam rings make recurring fountain maintenance more predictable.

A Cleaner Maintenance Habit
The Filter Tells A Story
Hair, residue, stale odors, and a clogged-looking filter are clear signs that the current setup is overdue for attention. A quick rinse removes loose debris, but it does not restore worn filter material.
Three Layers At Work
The white fibrous pad catches hair and visible residue. The black foam ring adds a pre-filter stage, while the activated carbon center addresses unwanted odors and stains.
A Simpler Maintenance Habit
Keep replacement components ready for the next fountain clean. Fresh layered parts make the drinking station feel clearer and fresher without replacing the entire fountain.
A Better Fountain Routine
- Wash reusable parts
Clean the reservoir, pump, and drinking surface during each fountain refresh.
- Replace visibly dirty parts
Do not rely on rinsing once the filter looks worn, clogged, or odor-laden.
- Check the fit
Compare the replacement shape and dimensions with your fountain before installation.
- Keep spares dry
Store unused components in a clean, dry place until the next maintenance cycle.

Questions and answers
Measure your fountain opening and compare the shape and dimensions with the replacement before ordering. The white filter measures approximately 1.69 inches wide by 2.99 inches long. The black foam ring measures approximately 1.10 inches at the inner opening, 2.36 inches at the inner length, and 3.15 inches at the outer length.
The set includes eight white filter pads and eight black foam filter rings. The filtration construction also includes an activated carbon center.
The white pad catches hair and visible residue, the porous black foam ring adds a pre-filter stage, and the activated carbon center addresses odors and stains.
Rinsing can remove loose debris, but it cannot restore a worn or odor-laden filter. Replace dirty components during the normal fountain-cleaning routine.
They are shown compatible with multiple stainless steel and plastic fountain designs. Confirm the dimensions and filter shape of your exact fountain before ordering.
No. Triple filtration addresses hair, impurities, odors, and stains, but it does not make water sterile or guarantee removal of every microorganism. Wash the fountain and follow its care instructions as well.
