This filter is a staple we always recommend to clients using PETKIT fountains. Many parents find maintenance daunting, but the 3-second, tool-free replacement makes it genuinely effortless for busy Hong Kong households. We always encourage staying on top of these replacements because that anti-slime layer is a lifesaver in our humid climate, preventing the build-up that can compromise water quality and, ultimately, your pet’s urinary health.

Keep your Eversweet Ultra water fountain performing at its best with the PETKIT Fountain Cube C. The high-density carbon filter significantly enhances water taste, while a specialized slime-resistant layer reduces buildup by 30%. Designed for effortless maintenance, the tool-free 3-second replacement provides 30 days of consistent, hygienic performance, easily tracked via the PETKIT App.
