The Harmsco TC/55-AM cartridges offer superior water clarity, polish, and sparkle for your swimming pool water. The TC/55-AM cartridge is composed of polyester with anti-microbial Silver Zeolite technology. Combining silver into the filter media enables the cartridges to help eliminate odor-causing bacteria and inhibit growth of destructive mold and mildew. Its pleated media offers up to 12 times more surface area than other cartridges, meaning removal of more dirt, sediment, and other particulates for longer runs and fewer change-outs.
Harmsco® SureSafe™ Silver Zeolite technology has been effective against more than 650 strains of bacteria, fungi and molds in laboratory environments. It has completed FDA testing and is registered with the EPA.
