#1 – Fleck 5600SXT 48,000 Grain Water Softener

Fleck 5600SXT is a top-rated whole house water softener and perhaps one of the most reliable models available on the market that come at a reasonable price.  It’s a powerful and comprehensive digital system packed with a lot of incredible features that make it outshine its competitors.

The unit is one of the best models from Fleck which is a brand owned by Pentair Water Treatment Company. However, although it’s manufactured by Fleck, there are several other brands that are selling it under their name.

Fleck also has four other similar models under the 5600SXT series that offer different grain options. They include the 5600SXT 32,000 Grain system, the 5600SXT 64,000 Grain system and the Fleck 5600SXT 80,000 Grain system.

All these models employ almost the same technology and design with the only thing setting them apart is the capacity. It’s a thoughtful consideration that gives you the opportunity to choose the right size for your home but still get the same quality system as the rest. Even much better is the fact that you can also pick the brand you like.

This review is a thorough analysis of the Fleck 5600SXT 48,000 Grain water softener and it will show you exactly what propels it to the top of our list as well as how it compares to the other three models.

#2 – Whirlpool WHES40E 40,000 Grain Water Softener

Whirlpool is a reputable appliance brand in the world and amongst the many products they manufacture are water softeners that really stand up against the competition with regards to performance, usability, and price. 

The WHES40E water softener is one of them and it does live up to Whirlpool’s great reputation. It’s a unit designed to provide the most optimal balance between value and performance.

The system boasts of highly-effective softening ability, an efficient regeneration process, and a quite large capacity of around 40,000 grains.

Besides the WHES40E water softener, Whirlpool has a few other models on the market that offer different grain options to meet the needs of various customers.

At the lower end is the Whirlpool WHES30E model which provides a capacity of 30,000 grain. It’s followed by the Whirlpool WHESFC model with a 31,000-grain capacity and the Whirlpool WHES33 model which offers 33,000-grain capacity. 

These systems are nearly identical in terms of design but differ slightly when it comes to softening ability, capacity and the extra features they come with as you will see in this Whirlpool WHES40E review.

#3 – Culligan Water Softeners [5 Series]

Culligan is a veteran in the water treatment industry and no doubt one of the top brands that provide the most reliable water solutions for residential and commercial use as well as industrial applications.

Currently, Culligan offers a wide selection of water softener models which gives you the opportunity to pick the perfect solution based on your specific problem.

This why in this review we decided to give you a brief overview of each of the five series of Culligan water softeners which includes:

These are the most sought after softeners from Culligan and we’re going to highlight the good and the bad about these systems to help your make a more informed decision if you are thinking of getting a Culligan water softener.

Culligan High Efficiency (HE) Series Water Softeners

The High Efficiency series covers Culligan’s entry-level dual-tank water softeners for home use and although they are considered as entry-level, the models in this series are some of the most advanced water softeners in the market today.

As the name suggests, these models offer the highest efficiency compared to all the other Culligan softeners when it comes to salt and water usage. They are specifically tailored to cut the running costs down to a bare minimum.

The water softeners within this series are divided into two categories, the HE 1-inch systems, and the HE 1.25-inch systems. They are very identical systems but differentiated by the size of the control valve they come with.

The HE Twin and Progressive Flow Series

The HE Twin and Progressive Flow series is a family of Culligan’s twin-tank water softeners which consist of the HE Twin tank coupled up with the HE Progressive Flow water conditioner to form a single dual-tank system.

They are essentially two Culligan’s High Efficiency systems combined together, a design that makes them super effective softeners that can deal with any water hardness.

The HE Softener-Cleer®

Based on the HE 1-inch series of water softeners, the HE Softener-Cleer is once again packed with Culligan’s advanced water softening technology except that unlike the HE series, the models in this series do more than just softening.

They are a combination of a water softener and a filtration system, thereby they not only eliminate hardness but also several other contaminants present in water.

The Medalist Series®

The Medalist series is one of Culligan’s most economic types of water softeners and the reason for this is because it doesn’t have all the bells and whistles which the HE series and the other advanced models come with. It consists of a more basic design but even so, the performance is still outstanding.

The Gold Series

Lastly, we have the Culligan’s Gold series. This is another Culligan’s series that present standard types of water softeners. However, these models offer a bit more versatility in terms of features which is one of the factors that set them apart from the water softeners in the Medalist series.

#5 – Kentico Water Softener [4 Series]

Founded in 1970, Kinetico Water Systems Incorporated is an internationally recognized brand and manufacturer of water treatment systems meant for residential and commercial applications.

The company is popular for its high-quality water softeners that are better in performance and more efficient compared to most models of other brands.

In fact, Kinetico is known for being the first company in the industry to pioneer the designing and production of a twin-tank demand-operated water softener that operates without requiring electricity.

This development transformed the water softening industry and it’s one of the biggest achievements that earned Kinetico the great reputation and popularity it still enjoys today.

The company has a large collection of water softener systems to meet any residential or commercial needs. The softeners are categorized into different series based on their type, technologies they are using and the various functionalities they offer. They include:

Since there are a lot of top models in each series for us to cover all of them herein, our Kinetico water softener review just like that of the Culligan will focus on the series themselves to give you a clear overview of what to expect from the softeners within each series.

The Kinetico Premier Series®

The Kinetico Premier Series stands out as one of the company’s best-selling line of water softeners. Basically, all the models in this series utilize the standard Kinetico dual-tank system and have been tweaked to ensure optimum efficiency and effectiveness.

The series is made up of two categories, the standard Premier Series and the Premier XP Series both of which offer exceptional performance and value as you are going to find out below.

Kinetico Powerline Series

The Powerline Series presents the most economical water softeners. The series is one of Kinetico’s lines of single-tank systems and unlike the other series, it’s electric.

There are four models within this Powerline Series, the PS 0840, PS 1040, PS 1054 and PS 1354x. Each of these models comes with an alternative version except the PS1354 which are the PS 0840x, PS 1040x, and PS 1054x.

The difference between these two versions is the type of valve they use with the later models including the PS1354x model featuring an adjustable regeneration sequence time while the former utilizes fixed regeneration sequence time.

Furthermore, all the 7 models offer two regeneration control options; timer control and metered control with time delay.

These options typically give you the opportunity to pick the right system for your home based on the quality of your inlet water and the desired system efficiency.

Kinetico Signature Series

Kinetico Signature Series consists of three models, the Signature 735, 935 and 1035, all of which are designed based on the company’s original twin tank water softeners.

These models are amongst the most durable softening systems in the market and they do a commendable job in removing water hardness.

Kinetico Essential Series

Closing our Kinetico Water Softeners review is the Essential Series which basically includes the same features as the Signature Series but with extra enhancements like rapid regeneration and AccuDial features.

This is one of the Kinetico Series (aside from the Powerline Series) that employs a single-tank design. It’s also the only series from the company with the most compact water softeners.

#6 – On The Go OTG4-DBLSOFT Portable Water Softener

The On The Go OTG4-DBLSOFT Portable 16,000 Grain water softener is customized specifically for RV enthusiasts and those looking for a portable water softener.  

One of the attractive things about this softener is that while it’s a very compact and portable unit, it provides almost the same capacity as many standard water softeners in the market.

What’s more, it comes with some nice feature that makes it a good fit for those who want a softener they can take with them anywhere. There are two other options offered by the On The Go which are the OTG3NTP3M and OTG3NTP1DS and we will look at them too in this review.
