A water softener provides one of the most effective solutions for dealing with hard water, which is water that contains at least 60 mg of dissolved minerals like calcium, magnesium, and manganese.

Although these minerals will typically not pose any serious health risk, having the best water softener is important because they often create a damaging buildup in the plumbing and water system.

Other issues associated with hard water include ashy and dry skin or hair, low-lathering of soaps, bad smell, and funny water taste.

Water softeners are available in several types which include the magnetic descaler, salt-based and salt-free types. Besides the type, there are also many other things that you need to take into account when shopping for a water softener.

Here we review 10 top-rated water softeners and also describe the different types and explain the factor to consider when shopping.

What To Check Before Buying Best Water Softener?

Even after deciding on the type of water softeners to go for, you will still need to pick between different brands and models. But this should also be easy if you consider the following things when shopping.

1. Portable or Standard Water Softeners

One of the first decisions that you will need to make is whether to go for a portable or standard water filter as the two are ideal for different situations.

The portable water softeners are designed to be easy to carry around and for your use on the go. And so if you move or travel a lot and would still want to get some soft water they are the right pick for you.

Standard water softeners are the kinds that require permanent installation in your water system. They are often larger and with a higher capacity than the portable types and they are the best whole house water softeners.

2. Size

As you are picking a water softener, it is important to make sure that you pick one that is the right size for your home. It should be able to handle the water demand of your home while still not being overly expensive or too large.

To determine the right size for your house, the two most crucial things to consider are the number of individuals in the house and the water that they use for drinking, washing, cooking and other things.

You can easily calculate the right size for you by multiplying the number of people with the average amount of water they use every day which in most cases is 75 gallons. However, the water softener size chart below makes things much easy.

3. Flow Rate

Like with water filters, the flow rate also matters a lot when it comes to choosing a water softener as it determines how much water that you get per minute.

The quicker the softening process the faster the flow rate will be. However, when it comes to the water softeners you will have to take into account the regeneration speed.

A good water softener should have a regeneration time of under 2 hours to ensure you never have to wait for long to get the softened water. But something like On The Go OTG3NTP3M that can regenerate in just 15 minutes is more ideal.

For the flow rate, it will vary from one type to the other and also between brands. But, a system that can deliver at least 5 gallons per minute should be good enough.

4. Brands

You cannot overlook the brand when it comes to shopping for a water softener. While it is true there are almost countless companies that make them, there are a few that stand out due to the quality of their products and their reputation.

Some of the best water softener brands are Aquasana, Culligan, Morton, Fleck, and WaterBoss.

Aquasana – A highly reputable brand and one of the oldest water softener manufacturers known for making long-lasting products backed by great customer support. And most of their products use reusable and environmentally friendly materials with minimum waste.

Culligan – Having been in the market for three-quarters of a century, Culligan has seen it all, and they not only make high-quality water softeners but also a variety of softening products.

Morton – More famously known as a table salt manufacture, and so it is only natural for them to make salt for water softening. Although they do not have many water softener models in the market, the ones they have are top-notch quality and highly rated by customers.

Fleck – Probably the most famous water softener brand and this is for a good reason because they make some of the best performing water softener models in the market. Their products are also relatively more affordable to offer the best value for money.

WaterBoss – A brand that focuses on making water softeners that use less fluid to ensure minimal water wastage which in turn also means that their devices will use less softening solution.

Given the performance, easy DIY installation, quiet operation, and relatively affordable price tag, this is the best water softener for the money in our list as it is hard to get anything similar without spending more.

While this system seems to take up a lot of cabinet space, this should not be a big deal as it is always recommended dedicating the cabinet under the sink entirely to the filtration system.

It is great for use in areas with very hard water, and it will save energy and increase the lifespan of your appliances significantly to save you even more cash.

Installation is also straightforward, and you will not need to do any plumbing modification to your water system, and it will work on any type of piping including PVC and PEX.

While this is still not as effective as the salt-based water softeners, you should still be able to notice significant improvements in water quality after some time because like all other electronic water softeners, it takes a while to be effective.

  • Weight: 18 pounds

For those that would like to get soft water on the go, this is the best water softener system for you as it is designed to be compact and easily portable.

Setting up is a straightforward process as it comes with all the necessary hardware and the manufacturer also provides detailed instructions. You will not need any tools for the installation and the unit does not use any electricity.

With a softening capacity of 8,000 grains and a regeneration time of as little as 15 minutes, this water softener is designed to offer long-lasting service and with minimum downtimes.

Although it might not be as effective in softening the water at high flow as other high-end models, this should not be a big deal as you can still get enough water even at a low flow and the quality makes it worth it.


  • Compact and highly portable
  • Quick regeneration
  • Easy no-tools installation
  • No electricity required
  • Full cradle base for maximum stability


  • Not good for softening at a high flow rate

  • Capacity: 10,000 grains
  • Flow Rate: 4 gallons per minute
  • Dimensions: 22 x 10 x 10 in
  • Weight: 9 pounds

Being the second most affordable water softener in our review, the M7002 by Watts Water Technology is designed to make water softening a simple and cost-effective process.

This high-quality water softener is also quite compact and highly portable to allow for use on the go. It has a full cradle base that will keep the tank more secure.

With its built-in drain line flow restrictor, regeneration is more effective while the custom flow valve will allow the regeneration to happen without the need to disconnect and connect the system.

Because this water softener uses common table salt, it will be cheaper and more convenient to use in the long run.

The instructions provided seem a little vague and incomplete, but this is not a dealbreaker because setup and installation of this water softener are quite straightforward. While the 4 gallons per minute flow rate is one of the slowest in our list, it is still good enough.


  • More cost effective water softening
  • Quick and convenient regeneration
  • More secure full cradle base
  • Relatively more affordable

It comes as a complete system to make installation easy and ensure it will be ideal for immediate use and with digital controls that include an informative display for easy setup.

There is also a flow meter that measures the water use and ensures regeneration only happens as needed to save salt and minimize water waste. The tank will come preloaded with the resin to make this an even more convenient water softener.

Another relatively more affordable electronic water softener that will make water softening a more cost-effective process for you.

This water softener is designed for easy DIY installation without the need to use any special tools, and it will be efficient enough in descaling the entire water system.

Also, it ensures that the water retains the good minerals to keep it healthy and great tasting. Because it does not require the addition of salt, it is more environmentally friendly and does not waste any water.

Since this is not a waterproof device, you cannot install it outdoors at the main water inline, but this should not be an issue as it will still be effective enough indoors. And the fact that it does not entirely remove the hard minerals should not worry you as this is typical of these types of water softeners.


  • Retains healthy minerals
  • More environmentally friendly
  • Descales entire water system
  • Easy DIY installation on both metal and plastic pipes
  • Lifetime repair/replacement warranty

Despite the relatively larger size and more complicated look, this system is quite easy to install as it comes with everything you need in the installation kit.

This water softener is the priciest on our list but the long service life and water quality make the price tag seem like a huge brain.

  • Easy installation and filter change
  • Does not demineralize the water


  • Quite an expensive system
  • Relatively low water pressure

The installation is quite straightforward because like with most of their other products, Aquasana supplies everything that you will need.

Like most salt-free water softeners, this is more of a conditioner, and so it might not remove all the hard minerals from the water but at least you will not have to deal with scaly buildups.

  • Salt-free water softening

Being a product from one of the best water softener brands, the performance is also quite impressive. And this is because the system does not use a lot of salt, but it is still highly effective in softening the water.

Also, it has a factory installed by-pass valve and provides a whisper quiet operation, and you will hardly hear any sound from it.

The fact that you cannot mount it outdoors should not be a big deal as it does not take up a lot of space. Also, despite the salt storage and control location not being well-thought-out, this will not affect the performance and convenience of the system.


  • Efficient softening with less salt use
  • Compact design to fit tight places
  • Faster regeneration time
  • Whisper quiet operation
  • Built-in bypass valve


  • Cannot be mounted outdoors

Types of Water Softener

Types of Water Softeners

There are four common types of water softeners which are dual-tank, salt-based, salt-free and magnetic water softeners.

1. Salt-Based Water Softeners

Salt-based water softeners are the traditional types like the ABCWaters ABCWS48-56SXT-10 and they are the most common option currently on the market. The water softener will work by cycling water through two tanks.

One of the tanks houses special beads and the other is for the brine or salt water. The water filters will work by swapping the hard minerals like calcium, iron, and magnesium with sodium ions from the water which then softens it.

The wide availability of these water softeners makes them relatively more affordable as there are many models available. Although the water may contain some traces of salts, it will not leave any scale deposits in the plumbing system.


  • Common and widely available
  • Relatively more affordable
  • Water will not leave scale deposits


  • Leaves salt traces in the water
  • Softening material can be pricey to replace

2.  Salt-Free Water Softeners

While the name might sound exciting as there is no salt, this is not actually a water softener as it will not remove the hard water minerals.

Salt-free water softeners like iSpring ED2000 are water conditioners that will not remove anything from the water. Instead, they will make it harder for the minerals to form some buildup inside the pipes.

Because they do not use any salt, these are not nearly as effective as the salt-based water softeners, but this also means that they will also be cheaper to run as you do not need to but any salt. And they also require relatively less maintenance.


  • Cheaper to run
  • Require less maintenance
  • Minimizes limescale buildup


  • Not proven to remove hard water minerals

3. Dual-Tank Water Softeners

Water softeners require regular recharging or regeneration after working on a certain volume of water. For the traditional salt-based water softeners, this means having to take the system offline for some time, and you will not be able to get softened water for that time.

The dual-rank water softeners are meant to address this problem by ensuring that you will get a constant supply of soft water throughout the day.

They achieve this by having multiple tanks which for most systems means two large iron tanks and one brined one. And so as one tank is regenerating the other one continues to soften the water.

These are the best water softener systems for families that require large volumes of softened water and they generally also have a faster flow rate when compared to many other types. However, they require a bigger initial investment.


  • Great for filtering large water volumes
  • No regeneration downtimes
  • More flexible tanks sizes


  • Relatively pricey

4. Magnetic Water Softeners

The magnetic water softeners like Eddy ED6002P-US are also salt-free softeners, and they are some of the most controversial types as many people seem to have varying opinions about their use. Like the salt-free types, they are more of a water conditioner than a softener.

Magnetic water softeners are clipped to an incoming water pipe and will then emit a magnetic field that then changes the properties of the minerals in the water. And it will also prevent the buildup of limescale.

These water softeners will not interfere with your piping system and will not require any installation or bypass valves.


  • No installation required
  • Does not require any plumbing detachment or bypass valves
  • Prevents nasty limescale buildups


  • Not very effective in water softening

Buying Advice: For those that have larger families and require a constant supply of softened water, the dual-tank is by far the best option while the more affordable conventional salt-based water softeners are ideal for small families. Magnetic and salt-free water softeners, on the other hand, are ideal for those that do not have very hard water and just want something to prevent limescale buildup.


Finding a good water softener should now be effortless as our review above provide enough recommendation.

For those looking for something inexpensive that still does a great job and is straightforward to install, the Watts Water Technology M7002 is perfect.

But, if you want a great all-round unit that is both highly useful for filtration and water softening, the iSpring RCC7AK is our best overall product.
