How does FROG Filter Mate Work?
It simply fits in the center of most filter cartridges. The one-piece design makes it stronger so no chance of breakage. Set the dial to the 4 month replacement date and drop it in the filter.
How long does FROG Filter Mate last?
4 months or whenever you drain and refill the hot tub.
What if FROG Filter Mate doesn’t fit in my filter cartridge?
You may set it in the filter well or skimmer tray. If it is too long, you can cut off part of the stem using the notches.
