Dolphin Spring Cartridge Filter Panel 9991433 (pack of 4 filters)
Before ordering, and to ensure the correct fit, please measure your current filter then compare the size of it to our product picture with the tape measures alongside the filter.
The Spring Filter Cartridges are designed to only trap larger debris and let fine debris pass through to prevent the cartridges from being clogged as quickly when the pool is especially dirty, like when you open the pool in spring.
