Product identity

This is a half-cubic-foot cation-exchange resin replacement rated at 16,000 grains capacity. It suits portable softeners that require exactly 1/2 CuFt of media and is FDA-compliant for potable water and food-contact use.

Capacity and interface limits

The media delivers a minimum total exchange capacity of 1.9 eq/l wet volumetric or 4.5 eq/kg dry weight. Operating temperature must not exceed 248°F (120°C) and the recommended pH range is 6 to 10.

Questions about this item

Is the half-cubic-foot bag the right size for my portable softener?

This bag holds exactly 1/2 CuFt of resin and is rated at 16,000 grains capacity, matching portable softeners that call for that volume.

How much hardness will the 16,000-grain rating actually remove between regenerations?

The 16,000-grain figure means the media can exchange up to 16,000 grains of calcium and magnesium before it needs a brine recharge.

What mesh size does the resin use and how does that affect flow?

The resin is screened to 16–50 mesh US Standard, giving a particle range that balances flow rate with ion-exchange efficiency.
