The On The Go Portable Water Softener are designed to remove hard water contaminates under the toughest conditions, providing you with soft water. This increases the alleviation of rough or dry skin while preventing rust staining, scaled build-up, and water spots. This is the perfect water softener to use when filling a salt water spa.

This works for 640-1600 gallons spas. It only takes a matter of 60 minutes to regenerate the softener, and on top of that only needs 2 boxes of salt.

This is the Double On The Go Portable Water Softener.
