Product Overview


You’ve seen the signs; spots on your clean dishes, mineral build-up on your showerhead, a scaly film on your freshly shampooed hair. You’ve got hard water. There’s a simple solution in the GE GXMH31H 31,100 Grain Water Softener. This self-cleaning system provides the maximum in hardness and iron removal available and an exclusive blending valve lets you control the level of softness. It’s powered by GE’s SmartSoft technology that learns your family’s water-use patterns, ensuring there’s always a freshly softened supply when you need it most. The heavy-duty storage tank holds up to 230 lbs of salt at once and a handy digital display counts down the days until it needs to be refilled, taking the guesswork out of routine maintenance. As an added bonus, the GE GXMH31H includes a built-in water filtration unit, eliminating the need to purchase a separate unit to remove unwanted tastes and odors from drinking water.


  • GE exclusive custom select blending valve: Allows you to select how soft you want your water
  • GE exclusive SmartSoft Technology: Ensures there is always plenty of softened water available by "learning" a family's water-use patterns
  • GE exclusive days to empty: Makes sure you never have to guess when to refill the salt tank

31,100 Grain Water Softener is rated 4.6 out of 5 by 9.
Rated 5 out of 5 by from Best Water Softener Ever! We've had the water softener for about 1-1/2 months. We hesitated on spending the extra money for having the softener & filter in one but so glad we did. This is the 4th softener that we've had, and it's fantastic. The difference in how the water feels from the one we replaced is night and day.

Rated 5 out of 5 by from Great Feature! I've been using the system for only a week and I am already getting incredible benefit from it. My skin feels so smooth without even using lotion!

Rated 4 out of 5 by from Easy installation Just installed, so haven't received the full benefit I know I will get from the water softener. It is a replacement for one I have had for over 15 years, which has worked wonderfully. Looking forward to the benefits of not having dry skin and dry hair that I experienced prior to having a water softener.

Rated 2 out of 5 by from More or less good Well... (deep subject...) , we tested our water after the installation. Quality between incoming system water, filtered water, softener & filter water, and bottled water. We were surprised to see that the incoming system water was the best. Not even after softened & Filtered water, plus a filter under the sink, did the water test good. So it was Bottled water first and then the system water coming in. Softener works great!!!

Rated 5 out of 5 by from Terrific Water Softener Purchased after moving into a new home where water was ridiculously hard and smelled or chlorine. No longer smell the chlorine and the water is much softer.

Rated 5 out of 5 by from Excellent features!! Very quiet! I put the water softener in myself without any issues. The appliance is easy to set up and easy to maintain. I love my water softener!
