FROG® Filter Mate® (01-14-3712 — also cross-referenced 01-14-3724, 8-05-0105, KTFILTER) is the mineral sanitizer that lives inside your filter cartridge. You still add dichlor or bromine — but only about half the usual amount, because FROG minerals are active sanitizers killing bacteria alongside the low chlorine level. The result is Fresh Mineral Water®: softer feel, less odor, easier on skin and surfaces.
- Fits inside virtually any hot tub filter cartridge core
- Cuts chlorine or bromine use up to 50%
- Lasts up to 4 months — replace with the season
