Dolphin Genuine Replacement Part Ultra-Fine Filter Panels (4PK) Part Number 9991425-R4

These work great. Keep them clean and dry when not in use and they should last a very long time. I left my old ones in the vac too long at the bottom of the pool and they pretty much stopped working, so I had to buy these. They're the same as the ones you get when you buy a new vac. They filter all the small things really well. Bonus points if you get the Blink-182 reference.

Good product, fair price and fast delivery!

This product is for my Nautilus Dolphin pool cleaner. Simply love it. Does a great job. Highly recommend this cleaner.

Used it to remove deciduous earth from my pool

The package arrived in perfect condition and on time. The measurement on the description is not correct. Each filter measures 5 1/4 by 11, which is exactly what I needed. Very happy with this purchase.

Works fine, how ever it needs filter clean up almost every day.

Arrived promptly; fit like the original; filtered just like the original (maybe better). Used on a Dolphin Premier.

We ordered these filters in March to prepare for this summer. We did. It know there were different sized filters for Dolphin cleaners. My husband opened one package and noticed right away they were too small. We contacted the seller to ask for an exchange-not a refund. This seller refused to give us an exchange. We will have to discard brand new filters due to size, and spend twice the $ to reorder new filters. Unacceptable customer service.
