Regeneration is the process of taking hard water and reducing it to softer water. The WaterBoss units regenerate faster than competition, which in turn saves homeowners on their water bill, salt usage and electricity consumption.

Randy V.

"This is the second WaterBoss® ProPlus 380 I have owned. Great compact unit. My son also purchased one because of my positive experience. Very easy to install and program - it is a breeze with very well-written instructions."

Melinda G.

"This is the second of two WaterBoss® softeners that we have owned. The first one replaced the water softener in our previous house. Then when we built our new home last year, we of course were impressed enough with the ease of using this product that we installed it in the new one."

Joe K.

"Great price and straightforward installation. No issues after almost a year in service and the water quality from the WaterBoss® is great! Definitely recommended for the value-minded DIYer."

Jim W.

"These are compact, economical, and easy-to-install water softeners. I had my first one for over 20 years, my parents had one that lasted just as long. They have great customer service and support based in the US."

Philip S.

"The water softener was easy to install, easy to operate, and runs flawlessly. It's been operating for 9 months now with zero issues. Would recommend!!"

Bill W.

"Easy DIY installation. Easy set up. Works great. Would highly recommend it."

William W.

"Easy install. Simple set up. Compact size. Works wonderful. My wife spent a little on her hair and water mattered to her. She loves this."

Linda C.

"This is the second WaterBoss® we have owned because we bought a different house and it didn't have a water softener. it is essential! I really like this model because it is easy to set and works great. Very easy to add salt to. This is the only brand we use. We had a different brand before having the 2 WaterBoss® brand softeners and this is much better."

Piero M.

"Great product. Ran solid for 15 years before the resin bed wore out. No repair issues ever. I replaced it with another of the same model."
