Welcome to RJ Filtration, Inc. We have been manufacturing cartridges for over ten years and we are recognized as a manufacturer of quality pool and spa cartridge filters. The cartridges of our Baleen branded filters are made of Reemay® spun bonded filter media that effectively restricts dirt and debris that is microscopic in size. The core in our larger pool filters are made of ABS which is engineered to be tough, impact resistant and can handle extremes in temperature. Our cartridge filters are very sophisticated and their core is designed with Aqua Flux Core. This allows a continuous and ample flow of water through the filter media.
