Aquasana SimplySoft Water Softener Review

As your search continues for the best water softening choice for your needs, you are wise to want to know more about the Aquasana SimplySoft Water Softener.

It’s a product that is made by a manufacturer that is well known in the industry and it’s well-reviewed by those that have bought one and used it.

This Aquasana water softening system is definitely worth taking a closer look at during your shopping process and that is exactly what I am going to help you out with here.

In this review, I will cover its good and bad points, discuss its best features in more detail, and tell you how it measures up against the competition.

Aquasana SimplySoft Salt-Free Water Conditioner Key Features


Here are the best traits of Aquasana Salt-Free Water Softeners:

SCM Mineral-Free Technology

This uses Aquasana’s own descaler technology. It’s a natural and impactful technology that inhibits scale buildup by transforming the dissolved hard minerals that are found in your household water into inactive microscopic crystals.

This causes calcium, magnesium, and other hard water-causing minerals to harmlessly pass through your home’s water distribution system without forming unsightly and problematic limescale deposits.

It also does it without the need for backwashing or having to periodically add heavy bags of salt to the system. This is why so many choose salt-free systems when searching for the best water softener.

Space-Saving Design

One of the biggest problems with traditional salt-based water softeners is that they have two tanks and need a drain line installed that takes up a lot of room.

That’s not the case with the Aquasana Salt-Free Water Softener at all. It comes with just a small-sized sediment prefilter and dual tanks that stack up on top of each other (Just 9” in diameter and 46” in height when set up).


It’s a design that allows this water softening system to be placed very close to a wall so it does not require much space to set it up.

Many Water Enhancing Add-Ons Available for Purchase

Aquasana is a company that is known for making water filtration products that can be easily paired up with others that they make to optimize your home water quality.

Here are some of the other Aquasana water treatment systems that can easily be combined for use with SimplySoft Water Softener:

  1. Point of Entry Water Filtration (Rhino Series) – This company makes one of the best whole home water filters that you will find in the marketplace as it reduces chlorine and many other harmful water contaminants.
  2. UV Light Disinfection – Water softeners and media filters have little impact on bacteria in water but UV light is very impactful when it comes to altering the DNA of bacteria, viruses, and other microorganisms into a harmless state.
  3. Reverse Osmosis System – These types of membrane filters are known to eliminate impurities in your tap water that are as small as 1-micron in size and that’s why good reverse osmosis systems produce some extremely pure drinking water.

Leaves Beneficial Nutrients in Your Water

Another problem with traditional salt-based water softeners is that they almost completely remove such essential nutrients found in water like calcium and magnesium.

That is not the case with the Aquasana SimplySoft Water Softener because it only alters hard water minerals such as calcium and magnesium so they are not able to form problematic limescale but does not remove them.


Once you put this Aquasana water softening product in place, you won’t have to worry about doing anything else to prevent nuisance limescale buildup for many years to come.

The company guarantees this device for a full 6-years and they will even give you your money back within 90-days if you are not satisfied with it.


Here are the good and bad characteristics of this Aquasana water softener:


  • Very Impactful for reducing scale buildup
  • Space-saving design
  • Many water enhancing add-ons available
  • Estimated 6-year useful life
  • Easy to install with kit
  • No electricity is needed to run the system
  • Minimal maintenance required
  • Leaves beneficial nutrients (calcium, magnesium) in your water
  • Aquasana is known for having top-notch customer service
  • 90-day guarantee


  • Just prevents scale buildup and does not remove hard water minerals
  • Somewhat pricey
  • Often ineffective with well water
  • Does not change the feel of your home’s water


I think this is one of the easier to install salt-free water softener models. DIY installation is even possible for those with just a small amount of plumbing knowledge.

As you can see in the photo below, items included in the package that will help make the installation of this product easier include:

  • Dual water softening tanks
  • Sediment prefilter
  • Prefilter cartridge removal wrench
  • Prefilter wall mounting bracket
  • Valve
  • Connections


Another reason that many people choose to purchase salt-free water softeners such as the Aquasana SimplySoft Salt-Free Water Conditioner is they require very little maintenance once they are set up and running.

All that you have to worry about with this model water softener in regards to maintenance is changing out its sediment pre filter every 6 to 12-months.

Other than that, you only need to periodically inspect the system for leaks and to make sure that nothing else looks out of place with it.   

How Do They Stack Up Against Competitors?

The Aquasana SimplySoft Salt-Free Water Conditioner compares very favorably with many other top salt free water softeners in its class.    

Is it the best salt-free water softener in the home marketplace? 

I don’t believe so but I will clarify that more by saying it was good enough to land on our review list of the best water softeners in the top 5 spots.

To show the significance of that, we took a closer look at many water softener models to come up with our review list of reliable water softening options.

My Aquasana Salt-Free Water Softener Summation

I like this salt-free water conditioner design from Aquasana. It keeps in line with all of the other Aquasana water treatment products as far as working well for the price ranges they are sold in.

You also have to like the fact that it is a virtually maintenance-free type of water softener which is unlike any type of common salt-based water softener.

I also like this water softening system because it’s DIY compatible and it also takes very little space to set up. That means garage and basement installations are never an eyesore when looking at them.

If it fits in your designated water softener purchasing budget and you like what you read about it here, I see no reason why you shouldn’t choose an Aquasana SimplySoft Water Softener.
