DolphinGenuine Replacement Part — Ultra-Fine Filter Panels (4PK) — 9991432-R4

I put these filters in our dolphin pool cleaner to upgrade the flimsy screens that came in it. I have to say, I’m impressed. They filter out the finest silt. I live in Georgia so lots of red clay. Neither my old Polaris cleaner or the factory filters on this dolphin ever caught the ultra-fine red silty clay material. They are also very easy to clean. Simply rinse with the hose and reinstall. We will see how long they last but I currently have no worries about their life span.

Great upgrade from the filters that came with the pool cleaner. Original filters only trapped leaves and debris. The ultra-fine filters trap tiny particles of dirt and sand. Excellent product.

Works as advertised

I got these to help collect the small sediment off the bottom of the pool and so far they have done a nice job. The fabric is more cloth like so I am not sure how long they will last but so far this year they have not shown any wear. If you have a Dolphin cleaner I recommend getting a set of these. The original filters are great for when you open the pool but once the big stuff is picked up you need these thicker filters to get the fine particles.

Perfect for keeping pool clean

Fit my machine perfectly. Love the fine grade of filter. Does a good job with ver fine particles.

The ultra-fine filters do seem to collect the fine algae and dirt particles, but simply rinsing them afterwards still leaves embedded fine particles. 4/5 stars because they will get clogged over time with particles that high pressure rinsing alone will not remove.

These are great! They really help the Robot catch fine particles instead of just blowing them through.
