DolphinGenuine Replacement Part — Ultra-Fine Filter Panels (4PK) — Part Number 9991467-ASSY

These filter panels remove the finest sand and dirt from the pool that the standard filters did not seem to get. That means less junk to clog my DE filter, reducing service intervals. If you have larger debris like leaves, you might want to do one cycle with the standard filters and one with the fine.

Bought these to replace the original filters in my dolphin active 30i. These popped in easily and work great.

This is a game changer. Installing was not that hard can only fit one way. Boy did this sure clean dust and dead algae. Very pleased and cleaned right up with garden hose and sprayer. Pool bottom is way sparkly now. I would recommend hopefully they last long

These filters fit and work well in our Maytronics Dolphin Proteus DX4 robot. This pleated filter system appears to capture algae and finer particles better than the screen style filters that ship with the robot. Swapping these filters for the original filters is easy and straightforward. Each panel is numbered to correspond with where it needs to be installed in the basket. It is impossible to put the filters in the wrong slot. It is recommended to remove the filters in order of their numbers 1-4 and replacing them is easiest when replaced in descending order from 4-1. Cleaning is easy with a moderate amount of water pressure from the garden hose. Great filters for capturing the finer particles in the pool.

Great filters
