Dolphin e10 filter upgrade
Compatibility
The Dolphin E10 uses a top-load fine filter basket. You can upgrade to an ultra-fine filter basket for improved filtration, though standard fine filters handle most pool debris effectively.
How to Verify Fit
- E10 filter basket dimensions: x 6" x 4"
- Top-load design with spring clips on both sides
- Blue mesh indicates fine filter; white mesh is ultra-fine
- Basket should sit flush and level when installed
Common Mistakes to Avoid
- Buying S200/in-ground Dolphin models filters - they look similar but are different sizes
- Using ultra-fine filters when pool has heavy debris (clogs quickly)
- Not rinsing filter after each use, reducing suction
- Forcing an ill-fitting basket which can damage the robot
When to Replace
Replace E10 filter baskets every 1-2 seasons depending on use frequency. Clean after every pool cleaning session. Replace immediately if mesh is torn or basket is warped.
Buying Tips
Stick with genuine Dolphin/Maytronics filters for the E10. Part number 9991440-ASSY for fine filter, 9991441-ASSY for ultra-fine. Third-party options exist but fitment can be inconsistent with this model.

Frequently Asked Questions
Can I use Nautilus CC filters in my Dolphin E10?
No, the Nautilus CC Plus uses different filter baskets. The E10 has its own specific basket size and design.
Should I upgrade my E10 to ultra-fine filters?
Only if your pool is already relatively clean and you want polished water. Ultra-fine filters clog faster with heavy debris. Use standard fine filters for regular cleaning, then run with ultra-fine for finishing.
How often should I clean the E10 filter?
After every cleaning cycle. Remove the basket, tap out debris, and rinse with a garden hose. This maintains suction and extends filter life.
