BFLICROY Cat Fountain Replacement Filters, 8-Pack for C1/D1 Models

BFLICROY replacement filters and pump sponges are an 8-pack set for compatible cat fountains, with a three-layer filter designed to help keep fountain water clean and fresh.

• Compatible with C1, C1 Classic, D1 and D1 Pro fountains, including 95 oz (2,809 mL) and 67 oz (1,981 mL) models — choose replacements for these fountain models and capacities.
• 8-pack of replacement filters and pre-filter pump sponges — provides filter and pump-sponge replacements in one set.
• Three filtration layers — target hair and residue, chlorine and odor, and heavy metals.
• High-density pump sponges — capture hair and debris before they enter the fountain pump.
• Recommended filter and sponge replacement every four weeks — supports a regular maintenance routine.

Fountain filters need to manage both what circulates in the water and debris that can reach the pump. This BFLICROY set is made for routine replacement in compatible automatic pet fountains, helping maintain water freshness while keeping hair and debris away from the pump. For fountains used by multiple pets, the filters and sponges may need changing more often than every four weeks.

How does the three-layer filter work?

The filter combines high-density cotton non-woven fabric, activated carbon and ion-exchange resin. The fabric layer catches hair and residue, while the activated carbon is designed to remove chlorine and odor. The resin filters heavy metals and helps improve water taste, which may encourage pets to drink more.

• Non-woven fabric handles visible hair and residue.
• Activated carbon helps reduce chlorine and odor.
• Ion-exchange resin filters heavy metals and improves taste.

Which fountains are these replacements compatible with?

BFLICROY filters and sponges fit C1, C1 Classic, D1 and D1 Pro cat fountains, including automatic fountains with 95 oz (2,809 mL) or 67 oz (1,981 mL) capacity. Match the fountain model and capacity to these compatibility details before choosing the set.

• For the C1 and C1 Classic models.
• For the D1 and D1 Pro models.
• Fits the stated 95 oz and 67 oz fountain capacities.

How should I prepare and replace the filters?

Before installation, soak each replacement filter in water for two minutes, then rinse it thoroughly under running water. This preparation helps prevent carbon dust from shedding into the fountain water. Replace the filter and pump sponge every four weeks as a general schedule, and change them more often when the fountain serves multiple pets.

• Soak the filter for two minutes before use.
• Rinse thoroughly with running water after soaking.
• Use more frequent replacements for multi-pet fountains.

This set suits cat owners maintaining a compatible C1, C1 Classic, D1 or D1 Pro fountain and wanting replacement filters alongside pump-protecting sponges. Its layered filter addresses hair, residue, chlorine, odor and heavy metals, while the pre-filter sponge catches debris before it reaches the pump. It is a replacement set for the stated fountain models and capacities.
