Fido Fave Cat Water Fountain Filter — 6-Pack for 5L Fountain

Activated carbon filters need replacing more frequently than most owners realize. After 3–4 weeks of continuous use, the carbon's adsorption capacity is saturated — it stops capturing the compounds it's meant to remove and can start releasing them back into the water. An overdue filter delivers worse water quality than a fresh one.

These filters are precision-cut for the Pokpet / Fido Fave 5L cat water fountain (PT004). Each uses 100% activated carbon for purely physical filtration: capturing hair, fine particles, and odor compounds without chemical additives. Replace every 3–4 weeks. One 6-pack covers roughly 6 months of maintenance at that interval.

• 100% activated carbon provides premium physical filtration — captures hair, particles, and odors with no chemical additives or byproducts.
• Fresher, better-tasting water encourages consistent cat hydration — particularly important for kidney health in older or indoor cats.
• Pure mechanical adsorption, no additives — safe and natural for even sensitive cats.
• Precision-cut for a secure, leak-free fit in the Pokpet / Fido Fave 5L cat fountain (PT004) — no trimming required.
• 6-pack covers roughly 6 months at the recommended 3–4 week replacement interval — the right amount to keep on hand.

Works Best On

Pokpet and Fido Fave 5L cat water fountains (PT004). Replace every 3–4 weeks for optimal water quality. In multi-cat households, replacing closer to 3 weeks is recommended as the filter accumulates more hair and particles from multiple cats.

Not compatible with: PT001-2 or PT003 (10L fountains — those use PT002 filters). Not designed for other brand fountain models.

How to Use

1. Rinse before installing: Hold the new filter under cold running water for 5–10 seconds to clear residual carbon dust from manufacturing.
2. Remove the old filter: Open the filter housing and remove the saturated filter. Discard.
3. Install the new filter: Insert in the same orientation as the original. Press firmly to ensure a secure, leak-free seat in the housing.
4. Run before your cat drinks: Let the fountain run for 2–3 minutes before your cat drinks — this clears any residual loose carbon particles from the new filter.

Frequently Asked Questions

How often do I need to replace the filter?
Every 3–4 weeks. In multi-cat homes, replace closer to 3 weeks. One 6-pack covers roughly 6 months of coverage at this interval.

What happens if I skip a filter change?
Once saturated, the activated carbon loses its effectiveness — the fountain still circulates water, but filtration stops working. Odors and particles return, and water quality drops below the baseline you'd have from a well-maintained fountain.

Is activated carbon safe for cats?
Yes — activated carbon is a widely used food-grade and water treatment material. It works by physical adsorption (bonding to particles and compounds) without releasing anything into the water itself. No chemicals, no byproducts.

Are these compatible with other cat fountains?
No — precision-cut specifically for the PT004 5L fountain filter housing. They won't fit other brand housings or the PT001-2/PT003 10L fountains (which use PT002 filters).

Do I need to rinse the filter before use?
Yes — a quick 5–10 second cold rinse removes loose carbon dust from manufacturing and prepares the filter surface for immediate adsorption.
