Portable Double Standard Water Softener by On The Go

The On-The-Go RV Water Softener fits perfectly

I have a 36 foot RV and spend my winters in Texas. The On-The-Go RV Water Softener fits perfectly in my back compartment. This is a great product - I have been looking for something like this for years!

Durable yet lightweight

Your portable water softener has served me well. I purchased the Double Standard Softener a few months back and have not had a single problem with it. It is durable yet lightweight. The rope handle really helps with transporting the softener in and out of my RV compartment. I am very pleased with my purchase and will be more than welcome to recommend you to any person or business. Thank you for the great service.

You would not believe the difference

We were at a Holiday Rambler Rally over the weekend and had been told how bad (hard) the water was at the campground. Well they were right, the water was so hard that the coffee made for our Friday night get together would make the powdered creamer look like curdled milk.
When I saw this, I got a hold of the store manager who was making coffee for Saturday morning and we used my Portable Water Softener to fill the pots for the coffee and tea. You would not believe the difference - the best tasting coffee all weekend and the creamer was as smooth as can be. I think I made a few believers this weekend.
We love your unit.
