Pleatco PCC105-PAK4-EC Pool Filter Cartridge Replacement for Unicel: C-7471-4, Filbur: FC-6470, OEM Part Numbers: 817-0131, 178584, R173476, White

Good quality and price compared to in store availability

Had tried to clean factory installed units way too long. These provided drop in replacement for my filter and quickly brought water pressure movement back into the pool up likely saved electricity in run time.

Convenient to order and less expensive at the pool store

There was a lot of pine pollen in my pool, the old filters were clogged put a new set of 4'pleatco filters in and pool is crystal clear now
