SUNRRAPleated Ultra Fine Robotic Pool Cleaner Filters for Dolphin Nautilus CC Plus, Supreme M400/M500/M4/M5, Replace Part# 9991432-R4, 4 Packs

My Nautilus CC Plus pool robot came with the house. It had the "fine" screen filters. I did not know there were options. Those fine filters worked great, but really small stuff like filter sand go through the screen.I bought these after-market "ultra fine" filters, and am very happy! Excellent filtration. I was worried they'd be hard to wash out, but they are very easy to rinse out with the garden hose.TIP: Always rinse your filters immedately after removing the robot from the pool. Things are harder to clean once that stuff dries. Plus, it's nice knowing the robot is always ready for the next time you want to throw it in the pool.

Filters that come with Dolphin cleaner are good for leaves and also fall or early spring clean up. These filters, SUNRRA Ultra Fine Filters, work best for fine dirt and sand for rest of the year.

Works with the Dolphin! Picks up fine sand and dirt! Great quality

Bueno, lo estoy usando

I love these replacement filters as they are cost effective and fit perfectly in my Dolphin pool robot cleaner. I will purchase more as these are effective and so much more affordable than other brands.
