Simply attach it to your filter cartridge, and the minerals automatically release into your spa water, destroying bacteria and controlling algae while reducing your dependence on harsh chemicals.

The FROG® Filter Mate is perfect for those with sensitive skin or anyone looking to reduce chemical exposure while maintaining crystal-clear, sanitized water.
Frequently Asked Questions
-
Replace your FROG Filter Mate every 4 months or when you perform a deep cleaning of your filter cartridge, whichever comes first. For optimal performance, we recommend setting a reminder on your calendar to ensure timely replacement.
-
The FROG Filter Mate is designed to fit most standard spa filter cartridges with threaded cores. It works with popular brands including Unicel, Pleatco, Filbur, and many OEM filters from manufacturers like Jacuzzi, Sundance, Bullfrog, Hot Spring, and Caldera. If your filter has a threaded top or bottom core, the Filter Mate will likely fit. Contact us if you're unsure about compatibility with your specific filter model.
-
Yes! The FROG Filter Mate works equally well with both chlorine and bromine sanitizing systems. It will reduce your bromine usage by up to 50%, just as it does with chlorine, while providing the same mineral sanitization benefits.
-
No, the FROG Filter Mate is designed to work alongside your existing sanitizer, not replace it entirely. It reduces your chlorine or bromine needs by 50%, but you'll still need to maintain a low residual level of sanitizer (0.5-1.0 ppm for chlorine when using minerals). This combination provides optimal sanitization while minimizing chemical exposure.
-
The FROG Filter Mate should be replaced every 4 months. We recommend marking your installation date on your calendar or using a waterproof marker to write the replacement date on the cartridge itself. If you notice increased chemical demand or water quality issues before the 4-month mark, it may be time for a replacement.
-
Yes, maintaining proper water balance is still essential. Continue to test and adjust pH (7.2-7.8), alkalinity (80-120 ppm), and calcium hardness (150-250 ppm) as needed. The Filter Mate reduces sanitizer needs but doesn't eliminate the need for balanced water chemistry.
-
The FROG Filter Mate is a standalone product designed for spas that don't have the FROG @ease system. If your spa already uses FROG @ease SmartChlor and Mineral cartridges, you don't need the Filter Mate. However, if you have a spa without the @ease system, the Filter Mate is an excellent way to incorporate FROG mineral technology into your water care routine.
