Our take

What to know before you buy one

We make whole-house systems with our own manufacturers and wholesale to water companies, and the same standards go into our store products.

Portable softeners are rated in grains like home softeners, but they're small, so on very hard campground water they run out faster than you'd think. Bring a hardness test strip and check the water at each site.

Pair it with a sediment filter before it. Campground water can carry grit that clogs a small softener fast. And flush it before storing for the season so it's ready next trip.
