The Unicel 4CH-23 R Compatible Pool & Spa Replacement Filter Cartridge is a compatible replacement filter also known as the Filbur FC-2400. This swimming pool filter contains a polyester media that improves efficiency and water flow through the system. This spa filter has a center core that is built to work hard for the filter, and it can bear a heavy load of debris, meaning greater time between cleanings. The compatible Unicel 4CH-23 filter is folded allowing for the dirt to go deep into the folds of the filter, keeping the pool or spa clean. The end caps of this pool filter cartridge are treated and resistant to bacteria and mold.
