Great Barrier 50sf
Caldera Old Design

 GREAT BARRIER PLEATS - High temperatures and the wet environment make an unprotected filter surface a target for the growth of bacteria. Great Barrier Pleats are made with genuine Reemay Advantage with Microban. Microban antimicrobial protection inhibits the growth of bacteria that can cause staining odors and degradation of the filter.  The unique continuous antimicrobial cleaning action of Microban makes the spa filter easier to clean, keeps it fresher between cleanings and ensures filter life.

PristineBlue non-chlorine pool & spa care may not be compatible with MicroBan filters. PristineBlue is a copper-based sanitizer. Microban filters may remove the PristineBlue from the water during the filtration process.
