Let's CUT to the chase Free Flow Cores = Cleaner Water

Nobody talks about cores. Why? Because all of our competitors use PVC pipe with holes drilled in them. Take a few seconds and look inside any of our competitor's cartridges and then look inside ours... you'll see the difference immediately. It's that simple. Our cores allow for the even flow of water through the entire cartridge which increases filtration, uses all the media, and makes it easier for the pump to pull more water through the cartridge. In the final analysis, Our Free Flow Cores are designed to be Cores!
