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.

Brandon S.

“We have owned our WaterBoss® 900IF iron filter and our 380 softeners for about 8 months and so far couldn’t be happier. We are a family of four and we use right around a bag of salt a month, and we have used a little over one bottle of potassium in the filter. Our water feels and tastes great. Hopefully, we are as pleased after years as we are after months.”

William B.

“I bought a WaterBoss® 900IF in 2009 at Menards. Installed it myself and it’s been great ever since. I check the potassium permanganate every two weeks and add to it about every six weeks. It’s been working flawlessly. When it finally wears out, I plan to buy another one.”

Marc J.

“I have 2 model 900 softeners (in 2 separate buildings). They are super reliable and well-built. I also installed a model 950 and a model 700 in my adult kids’ homes…..I absolutely love them.”

Tram N.

“I recently purchased and installed a 900 series WaterBoss® softener. The construction was solid and easy to install and set up. The water was soft and clean, using about 40 lbs of salt per month. The system is reliable and trouble-free. I strongly recommend WaterBoss® for water softening equipment.”

John F.

“WaterBoss® 900 great water softener, I have only had it a year so far. I like that it’s smaller than normal softener, and only holds 1, 40 lb bag of salt per month which is good – no salt jamming whatsoever. Will buy it again!!”

Todd D.

“This is my second unit. My first was installed in 2007. It lasted until 2022. Make sure you put a good filter in front of it. The new one works perfectly. I have the 900 series.”

Ronald W.

“I purchased the WaterBoss® 900 from Home Depot and it was a great decision. I am able to get the desired softness of my water. If you have the correct plumbing as I have, it is very simple to install (follow the instructions). It’s nice and compact, occupying a very small space in the garage. The WaterBoss® internal water filter works better than the Whirlpool whole-house water filter. The WaterBoss® decreases my water hardness from PH-12 to PH-7 using one 40-pound bag of salt each month. I would have no problem recommending the WaterBoss® to a good friend.”

Loric L.

“I purchased the WaterBoss® 900 from the Home Depot online and picked it up at the local Home Depot store. I did some research on the internet and consulted with a friend who is a plumber. I made my decision based on quality, efficiency, and value. The WaterBoss® was installed in May of 2021 and is performing as advertised by the manufacturer, I’m pleased with my purchase and would recommend this product to others looking for a dependable water softener. Some of the features that I like are the quick regeneration time of fewer than 30 minutes, less salt and water used to regenerate, the easy-to-use controller programmer set up for operation, and the compact size of the WaterBoss® 900 unit.”

Duane S.

“When it came time to replace our old water softener, a plumber friend recommended WaterBoss®. I purchased one and had him install. Compared to the other softeners the difference is night and day. I use less salt for the same amount of softness, and it is so much easier to set up the electronics. It is easier to install, using much less storage area for the unit. Its smaller size makes it much easier to add salt when needed. I have already recommended it to a couple of my friends. Had one question and called the company. The lady that answered answered my question promptly and also provided me with some other information. Very, very satisfied with the unit and the company. If you need a new softener this is the one to buy…..By the way, it is a Model 900.”
