About the FROG Filter Mate
The mineral sanitizer that cleans and softens hot tub water inside your filter cartridge. While you’ll add dichlor or bromine separately, you’ll need half the usual amount, because our FROG minerals are active sanitizers. The result is you kill bacteria two ways – with minerals and a low level of chlorine or bromine. We call it Fresh Mineral Water® because it looks and feels amazing.
How does the FROG Filter Mate work?
The FILTER Mate mineral sanitizer fits easily into the center of your spa’s filter cartridge. It is a one-piece design that can be shortened if necessary. The unique design draws in your spa water through the openings in the cap and sides and circulates it through our patented mineral formula dispensing a low level of minerals into the spa. Simply supplement with 1 ppm of chlorine or bromine.
