The OYES Cat Water Fountain Filters come in an 8-pack designed for the 2.0L/67oz round stainless steel cat fountain. This bulk pack makes routine maintenance quick and cost-effective, so you can keep the fountain flowing without interruption.
Quality filtration can support a steady water flow that pets enjoys. The filters combine multiple layers to help manage hair and residue, reduce odors, and soften water, which may result in water that your cat finds appealing. This set is ideal for busy homes, multi-pet households, or environments where you want to simplify refills and replacements.
The cotton layer catches hair and fine debris, the activated carbon helps mitigate odors, and the ion exchange resin softens the water. Together, these elements aim to support a cleaner, clearer water stream. While results can vary by water source and pet, many owners notice a steadier fountain flow and reduced splash after replacing filters.
What’s inside the box? A practical 8-pack of replacement filters, ready to keep your cat’s fountain replenished and performing well. This product is a replacement filter set intended for consumer use and is not a medical device or treatment.
For best results, match the filter to the 2.0L/67oz round stainless steel model and follow the soaking step before first use. If you have multiple cats or high drinking rates, you may find yourself swapping filters a bit more frequently. The goal is steady water flow and a clean-tasting water experience that encourages regular hydration.
Q: How often should I replace the OYES cat fountain filters?
A: Replace every 2 to 4 weeks depending on your cats' drinking frequency and the number of pets.
Q: Are these filters compatible with other fountains?
A: They fit the 2.0L round stainless steel cat fountain; verify your model’s size to ensure a proper match.
