9991432R4 Pool Cleaner Filter Compatible with Dolphin m400, m500, Nautilus CC Plus, 4Pack UltraFine Filter Replacement Robotic 9991432R4

Works great for nautilus cc plus

I read a ton of reviews before purchasing a pool vacuum and one thing that came up was that I absolutely NEEDED to purchase a filter like this if I wanted to make the most of my vacuum. I got the dolphin nautilus and when it came, the included filter looked like it would only filter leaves and other larger items. No way would that thing filter out dirt, sand, small bugs, etc. It was so obvious that I didn't even bother using it, I just bought these filters and snapped it in and let the vacuum go. These filters are a must have! I can't believe the $800 vacuum I bought didn't come with this. I've been using it a few months and it fits perfectly and cleans easily. Absolutely would buy this again, seems like it'll last a while too. 10/10!

Fits dolphin ccplus perfectly. Been using for several months now. No issues. No longer have to vacuum with skimmer vacuum. Very happy!😊Thank you for an excellent product

The corrugated structure of these filters increases the surface area resulting in a more efficient filter.

Worth it. It picks up plaster dust from mew pool install and that stuff is super fine gets sand and just everything

Good quality. For our cleaner perfect.
