PETKIT FILTER UNIT 3.0
Fresh Water Starts with a Fresh Filter
Keep your compatible PETKIT Eversweet fountain performing at its best with genuine PETKIT Filter Unit 3.0 replacement filters. Each five-pack uses multi-layer filtration to help capture hair and debris, reduce unwanted tastes and odours, and filter certain dissolved impurities from your pet's drinking water.
Multi-Layer Filtration for Fresher Water
Filter Unit 3.0 combines a high-density filtration layer, coconut shell activated carbon and ion exchange resin. Together, these layers are designed to capture common impurities while helping reduce unwanted tastes and odours.
High-Density Filter
Helps capture visible impurities such as pet hair, dust and debris.
Coconut Shell Activated Carbon
Helps adsorb unwanted tastes and odours to support fresher drinking water.
Ion Exchange Resin
Adds another filtration stage designed to help reduce certain dissolved impurities in the water.
Compatible PETKIT Eversweet Fountains
PETKIT's current manufacturer specifications list Filter Unit 3.0 for the Eversweet 3 Pro, Eversweet 3 Pro (UVC), Eversweet Solo 2 and Eversweet Solo SE.
PETKIT Australia's distributor listing also identifies compatibility with some earlier Eversweet models. If you have an older fountain, we recommend checking your exact fountain model before purchasing.
Replace Approximately Every 2–4 Weeks
PETKIT recommends an optimum replacement cycle of approximately 2–4 weeks per filter. Actual replacement timing can vary with fountain use, water quality and filter condition.
Before installing a new filter, rinse it thoroughly with clean water. If your compatible fountain provides a filter reminder, follow the fountain or PETKIT app instructions when resetting the filter status after replacement.
Why We Chose It
If you've invested in a PETKIT water fountain, replacement filters are an essential part of keeping it maintained. This genuine PETKIT five-pack gives you the correct filtration materials and fit for compatible Eversweet models.
A five-pack also means fewer last-minute filter purchases — particularly useful when your cat's fountain is part of their everyday hydration routine.
