Product Description


MARCH 10, 2024:  In an effort to streamline our focus, we are no longer going to sell SPA FROG FILTER FROG.  It's a FABULOUS product, so grab it while you can!   We have (10) SPA FROG FILTER FROG (FILTER MATE) left! 


IF YOU ORDER 5 SPA FROG FILTER FROGS you will also receive one FREE!  Order while supplies last!

SPA FROG Filter Frog offers mineral spa care that easily fits in your spa filter.  Using recyclable materials and no electricity means this mineral purifier an Eco-friendly product, purifying your water naturally with less waste.

Filter Frog's unique design draws water in through the openings in the cap and the scooped louvers at the top and circulates it through our mineral formula for the greatest effectiveness. Water is then released through the bottom openings. Simply supplement with a low level of bromine (1PPM) or chlorine (.5PPM).  Use a spa ozone generator with your Filter Frog for the best hot tub water imaginable.

This SPA FROG Filter Frog lasts 4 months.  Simply set the easy reminder dial to help you remember when to replace it.

SPA FROG Filter Frog:

  • Fits inside most filter cartridges, skimmers or filter wells
  • No assembly required - support rod is permanently attached
  • Supplement with .5 PPM chlorine or 1.0 PPM bromine
  • Features an easy-to-set reminder dial for replacement (we love this feature!)
  • Made from recycled materials.  Expired SPA FROG vessels can be recycled at your recycle center

Mineral purifiers reduce the need for chlorine and bromine 50%.  Adding ozone to the picture makes it 60-90% less spa chemicals.  Luxurious water without the harsh residue.

  1. Keeps my tub clean with fewer chemicals 5 Star Review

    Posted by on 24th Feb 2021

    We had let our tub get into bad shape, and after using the articles here on this website to get it back in order (replacing the ozonator etc, SO grateful to the folks here!) we also started using a mineral frog. That plus the ozone, and only a tiny bit of bromine is required to keep it nice and clear. Definitely recommend.
