Keep your Eversweet Ultra Cat Water Fountain fresh with PETKIT Fountain Cube C. High-density carbon enhances water taste, while a slime-resistant layer reduces buildup by 30%. Tool-free 3-second replacement provides 30 days of consistent performance, tracked via PETKIT App for effortless, hygienic maintenance.

Every refill is an extra boost.

Standard filters leave gaps and messy black dust. Our high-density sintered core forces every drop through a solid carbon wall, eliminating bypass and residue. The result is pure, spring-like water with a taste pets instinctively love.

Bye-bye, slippery feeling.

Tired of scrubbing that "yucky" film off the tank? The PETKIT Fountain Cube C slows down slime buildup by 30%, keeping surfaces feeling cleaner for longer and significantly cutting down your deep-cleaning chores.

Change in a snap.

Maintenance shouldn't be a project. Simply pull out the old core and push in the new one. No tools, no disassembly, and no mess, just a 3-second swap that gets you back to your day.

A fresh month, guaranteed.

Most filters quit after a few weeks, but this cube is built for the long haul. It provides a full 30 days* of consistent, high-speed filtration that works just as hard on Day 30 as it did on Day 1.

*Testing conducted by a third-party laboratory.

Always in the loop.

The PETKIT app tracks the exact lifespan of your filter cube. Check in anytime for real-time updates, and receive an automatic reminder when it’s time for a fresh swap.
