Maytronics Dolphin Filter Cartridges, Set of 4

These cartridges are far better than the ones that come with the pool sweep. The factory cartridges are fragile and made of thin material that tears easily. These are built far better with corrigated material. It also traps smaller particles.

We gained our pool when we bought our home but knew little about it. It already had an automatic pool cleaner. The filters looked like they had seen better days so I pitched them at the end of the swim season last year. Little did I realize that they were so expensive to purchase! When I searched for the filters by the name of my pool cleaner I couldn't find them. The Dolphin name came up though and when I checked, the dimensions were correct and they looked like the ones I had thrown away. They fit perfectly and clean up well. I have been very pleased with my purchase and super impressed with poolzoom.

Excellent product. Catches the smallest sand and dirt. Works great. Would recommend it to every one.

We will see how long they last.

Was the exact product I was looking for.

Love the Dolphin Nautilus with one reservation. The tabs on the filter cartridges are very delicate, and easily break off. Lost three tabs on each of two filters in one month. Also, the instructions for dismantling and cleaning the impeller indicate using a large screw driver in the slot to unlock the lid, but that won't work without breaking the delicate part. There is a lever beneath the cover that allows easy unlocking.
