Ultra Fine Filters Compatible with Dolphin Nautilus CC Plus (Not for Nautilus CC), Nautilus CC Supreme, M200/M400/M500, Part # 9991432-R4, Pleated Pool Cleaner Replacement Part, 4 Packs

Way better than the filters that come with our Dolphin vacuum. Catches much more dirt and debris

These filters work much better than the ones that came with the robot

These fit our Nautilus Supreme pool vacuum perfectly and are the ultra fine filters that capture the smallest particles in the pool, as well as leaves and other debris. Very glad we bought them as the water cleared up quickly after using them as it filters water thru it very ably and removes even invisible contaminants from the pool water.

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.

Bueno, lo estoy usando

I bought these last year. They are so good that it traps any algae (that you don’t even notice) as the BOT cleans the walls. Picks up the finest grains of dirt. Kept my pool looking gorgeous all summer and saved me so much work!! They are so easy to clean too!!

I took a chance on these since they are not the name brand, but they seem identical and work just as well as the originals and for a better price. Very happy with these and when I need another set I will buy these again.

WORKS GREAT !!!
