Preparation Before Use
Before installing a new filter, proper preparation is crucial to activate its performance and remove any residual dust from manufacturing.
- Soak the Filter: Submerge the new filter completely in clean water for 5 minutes. This helps to activate the activated carbon and ion-exchange resin within the filter.
- Rinse the Filter: After soaking, rinse the filter thoroughly under running water for 30 seconds. This step removes any loose carbon particles or dust, ensuring clean water from the start.

Installation
Follow these steps to install the replacement filter and pre-filter sponge into your oneisall cat water fountain.
- Disassemble the Fountain: Turn off and unplug the fountain. Carefully remove the top tray and any existing filter components.
- Remove Old Filter and Sponge: Discard the used filter and pre-filter sponge.
- Install New Filter: Place the prepared replacement filter into the designated filter slot in the fountain's upper assembly. Ensure it sits securely.
- Install New Pre-filter Sponge: Locate the pump unit. The pre-filter sponge typically fits over the pump's intake to prevent larger debris from entering the pump. Gently slide the new sponge onto the pump.
- Reassemble the Fountain: Carefully reassemble the fountain components, ensuring all parts are correctly aligned.
- Refill Water: Fill the fountain with fresh water to the appropriate level.

Maintenance
Regular maintenance of your filters and fountain is essential for providing clean, fresh water to your pet.
Filter Function and Deep Filtration
The oneisall replacement filters utilize a multi-layer filtration system:
- Non-woven Fabric: Catches hair and larger debris.
- Activated Carbon: Deodorizes water and removes impurities.
- Ion Exchange Resin: Helps to remove heavy metals and soften water.
- Pump Sponge: Prevents hair and debris from entering and clogging the pump.

Recommended Replacement Cycle
- For optimal filtering results and water quality, replace the filter every 2 weeks.
- If you have multiple pets using the fountain, or if the water appears cloudy or has an odor, increase the frequency of fountain cleaning and filter replacement as needed.
- The pre-filter sponge should also be replaced every 2 weeks, or sooner if it appears heavily soiled.
Troubleshooting Common Issues
If you experience issues with water quality or fountain performance, consider the following:
- Reduced Water Flow: Check if the pre-filter sponge is clogged with hair or debris. Clean or replace the sponge. Ensure the main filter is not excessively dirty and replace if necessary.
- Unpleasant Odor/Taste: This indicates the filter's activated carbon is saturated. Replace the filter immediately. Ensure the fountain reservoir is cleaned regularly.
- Cloudy Water: This suggests the filter is no longer effectively removing particles. Replace the filter and thoroughly clean the fountain.
