Operating Principle (Filtration System)
The NPET replacement filter utilizes a comprehensive 5-stage filtration system to ensure your pet receives clean and healthy water:
- High-density Sponge: Catches hair, debris, and other large particles.
- Activated Carbon: Effectively removes odors and chlorine from the water.
- Ion Exchange Resin: Softens hard tap water, reducing mineral buildup.
- Medical Stone: Further removes heavy metals and other harmful substances.
- Non-woven Fabric: Prevents mucus production and ensures water clarity.
This multi-layer approach provides fresh, odorless, and clean water for your pets.

Maintenance Recommendations
Regular maintenance of the filter and pump sponge is crucial for optimal performance and your pet's health:
- Clean the Pump Sponge: It is recommended to clean the pump sponge once a week to remove accumulated debris and maintain proper water flow.
- Replace the Filter: Replace the main filter every 2 to 4 weeks. The exact replacement frequency depends on the number of pets using the fountain and the water quality in your area. More frequent replacement may be necessary for multiple pets or harder water.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Black particles in water after new filter installation | Loose activated carbon from the new filter. | Ensure the filter is thoroughly soaked and rinsed for at least 30 seconds before first use. This removes loose carbon. |
| Reduced water flow from the fountain | Filter or pump sponge is clogged with debris (hair, food particles). | Clean the pump sponge weekly. Replace the filter if it has been 2-4 weeks since the last replacement, or if cleaning the sponge does not restore flow. |
| Water has an unusual odor or taste | Filter is saturated and no longer effectively removing odors. | Replace the filter immediately. Ensure regular filter replacement every 2-4 weeks. |
