Our center cores are molded and provide for a
free flow of water through them. They achieve
approximately 20% better filtration efficiency, with
less wear & tear on the spa pump, and less energy
The end caps of the cartridge are made with
proprietary antimicrobial, crack-resistant
polyurethane, resistant to chlorine and bromine.
The filter material we use will not break down, and
contains nothing that may cause a foam buildup.
