3. Preparation Before Use
Before installing a new filter, proper preparation is essential to ensure optimal filtration and remove any residual dust from manufacturing.
- Soak the Filter: Submerge the new activated carbon filter in clean water for 5 minutes. This activates the filter material.
- Rinse Thoroughly: After soaking, rinse the filter under running water for 30 seconds. This step helps to wash away any loose carbon particles.

4. Filter Replacement Guide
Follow these steps to replace the filters and sponges in your oneisall cat water fountain (models PW13, PW14):
- Disassemble the Fountain: Unplug the fountain and carefully disassemble the top tray and pump unit.
- Remove Old Filter: Locate the filter housing, typically within the pump unit or top tray. Remove the used activated carbon filter.
- Remove Old Sponge: Remove the old pre-filter sponge, usually found around the pump intake.
- Insert New Sponge: Place a new pre-filter sponge around the pump intake. Ensure it fits snugly to prevent debris from entering the pump.
- Insert New Filter: Place the prepared new activated carbon filter into its designated housing. Ensure it is correctly oriented and seated.
- Reassemble and Refill: Reassemble the fountain components. Fill the water reservoir with fresh, clean water to the appropriate level.
- Power On: Plug in the fountain. The water should begin to flow through the new filtration system.

5. Maintenance Schedule
Regular replacement of filters and sponges is crucial for maintaining water quality and fountain performance.
- Activated Carbon Filter: Replace every 2 weeks for optimal filtration results.
- Pre-filter Sponge: Replace every 2 weeks, or more frequently if visibly dirty.
If you have multiple pets using the fountain, it is recommended to increase the frequency of both fountain cleaning and filter replacement to ensure continuous access to clean water.
