This replacement filter is made from quality Reemay brand filter fabric. 

This one has polyester pleats and antimicrobial endcaps.   All these filters do the same job – filter the spa water.  It is important to clean any spa filter regularly and replace it about once a year with a new one.  Extend the filter life by using either an overnight filter soak or a filter cartridge cleaner spray.
