Description

This is the Maytronics 9991463-R4 spring filter kit, the genuine Dolphin replacement filter set for the larger basket style cleaners.

Which cleaners it fits

Maytronics lists the kit for the Dolphin S300i and S300, the Active 30 and Active 30i, the Triton Plus with PowerStream and the Triton with PowerStream, and the Nautilus CC Pro. These all share the same filter basket, which is why one kit covers the group.

Spring filters versus fine cartridges

Dolphin baskets take more than one filter style, and the spring type is the standard set for these models. If your basket currently holds ultra fine cartridges, that is a different part number, so look at what comes out before you order.

When to replace

Filters are consumable. Rinse them at the end of every cycle and change the set when the media stays gray after a wash, when a panel tears or splits, or when the cleaner runs its full pattern and still leaves a fine film on the floor.
