Metal Foam Spa Purifier

Reduce chlorine or bromine usage by up to 90%, with safe, effective Metal Foam Spa Purifier. As spa water passes through the copper/silver foam, the metal mesh disc destroys most of the same bacteria as standard chemical treatments, including E. coli and legionella pneumophilia. Once a month remove the disc and backwash with a garden hose; replace disc twice annually. You'll still need to chlorinate (small amount of bromine or bleach after use) to remove non-bacterial spa contaminants (sweat,products). This ecological gem lets you enjoy the relaxing health benefits of clean, hot water, and reduce your dependence on toxic chemicals at the same time. Simply drop the disc into the skimmer or into the center hole of your spa's filter. Includes disc-holder, and two metal foam discs. USA.
