Culligan provides water treatment systems – mainly softeners & filters – and water solutions for homes and offices as well as commercial and industrial applications. This includes the company’s delivery service where you can order filtered bottled water on a monthly basis.

Culligan was established in Northbrook, IL in 1936 and offered nothing but water softening solutions for residential use back then. Today, the headquarter is based in Rosemont, IL and the product range is much wider.

Since the beginning, Culligan has focused on building a network of franchises with local experts that act as company representatives. These experts help potential new customers to have their water tested and come up with the supposedly best treatment solution. Their service also always includes system installation & setup, and maintenance and repairs as needed.


Why Culligan?

In this review, we are going to cover the good, the bad and the ugly. Let’s start with the good. What are the reason for you to opt for a Culligan water softener?

  • Regenerate Only When Needed – Culligan softeners measure your water usage and only regenerate when necessary. This saves you money, water and salt.
  • Proportional Brining – Some systems allow for proportional resin regeneration, so that only the part of the resin bed that has been exhausted regenerates which further reduces salt consumption.
  • Soften + Filter – Some Culligan softeners will also filter your water in case you want to drink it. The HE Softener-Cleer even reduces sulfur, iron and water odor. The HE Municipal Water Conditioner shines in chlorine removal and helps to eliminate other tap water contaminants such as pesticides.
  • Convenience – If you purchase a smart brine tank, it will automatically monitor the salt level and lets you know how many days of salt are remaining. Convenient, isn’t it?
  • Tested & Certified – As far as we know, all Culligan softeners are tested and certified by the WQA against NSF Standards 44 + 372 and CSA Standard B483.1 that guarantee effective reduction of hardness (calcium and magnesium), barium, and radium 226/228. Some models also come with additional certifications.
  • Done-for-You Solution – Like we said, purchasing a Culligan softener also includes hooking up the system, initial programming, the maintenance part and potential repairs. Some systems will even send automatic service notifications directly to your Culligan expert.
  • Different Payment Plans – You can purchase, you can rent, you can finance. Culligan offers payment options for everyone.
  • Satisfaction Guarantee – It’s not much, but at least you get a 30-day money-back guarantee. Culligan will remove your softener and refund the purchase price if you are not satisfied with the product.

Reviews of Culligan Water Softeners

Culligan offers way too many different water softener models for us to check them all out. There is:

  1. The High Efficiency (HE) Series
  2. The HE 1.25 Series
  3. The HE Municipal Water Conditioner
  4. The HE Softener-Cleer
  5. The HE Twin and Progressive Flow
  6. The Medallist Series
  7. The Gold Series

This is why we decided to give you an overview of the High Efficiency Series, the Medallist and the Gold Series, which are the most sought after Culligan softeners.

But first, the following video presentation by Culligan quickly covers each of the models (except for the Gold Series).

Culligan HE High Efficiency Water Softener

As the name suggests, the High Efficiency Series offers you the highest efficiency of all Culligan softeners in terms of salt and water usage. The goal: Reduce running costs to a bare minimum. Therefore, you have the option to choose between different tank sizes as well as regular downflow or upflow regeneration.

Stats (downflow regeneration only):

  • 4 different sizes
  • For small to larger families and homes
  • Maximum hardness level: 75 – 99 gpg
  • Total ferrous iron capacity: 5 ppm
  • Rated service flow rate: 9 to 10.6 gpm
  • Total softening capacity: Approx. 30,000 to 90,000 grains
  • Softening resin: 1.0 to 3.0 cu. ft.
  • Salt storage capacity: 250 lb to 600 lb
  • Operating pressure: 20 – 120 psi


  • Culligan’s most advanced softener series
  • Applies salt and water-saving technology
  • Different operating modes to choose from
  • Brine tank monitors salt level and detects bridges, eductor line plugging and tank overfilling
  • Wireless remote allows remote control and displays softener’s current status

  • Allows scheduled salt delivery
  • NSF certified
  • Can handle small amounts of clear-water iron
  • Warranty covered

Culligan Medallist

Compared to the HE Series, the Culligan Medallist is more affordable since it does not feature all the bells and whistles that the former comes with. For example, the remote display + modem are optional. Also, warranties are available separately.


  • 4 different sizes (Medallist and Medallist Plus)
  • For small to larger families and homes
  • Maximum hardness level: 75 – 99 gpg
  • Total ferrous iron capacity: 5 ppm
  • Rated service flow rate: 5.9 to 10.2 gpm
  • Total softening capacity: Approx. 25,000 to 60,000 grains
  • Softening resin: 0.7 to 2.0 cu. ft.
  • Salt storage capacity: 250 lb to 375 lb
  • Operating pressure: 20 – 125 psi


  • Most affordable
  • Different operating modes to choose from
  • NSF certified

  • Can handle small amounts of clear-water iron
  • Warranty covered (only optional?)

Culligan Gold Series

And lastly, Culligan’s Gold Series. There is not much new to be said here, to be honest. The manufacturer advertises the system as “customizable” which we think refers to the option of choosing different tank sizes. Just like the HE Series, the Gold Series makes use of demand-initiated regeneration which only triggers when necessary to minimize salt use and wastewater production which in turn saves you money.


  • 4 different sizes
  • For small to larger families and homes
  • Maximum hardness level: 75 – 99 gpg
  • Total ferrous iron capacity: 5 ppm
  • Rated service flow rate: 9 to 10.6 gpm
  • Total softening capacity: Approx. 30,000 to 90,000 grains
  • Softening resin: 1.0 to 3.0 cu. ft.
  • Salt storage capacity: 250 lb to 600 lb
  • Operating pressure: 20 – 125 psi


  • Applies salt and water-saving technology
  • Different operating modes to choose from
  • NSF certified

  • Can handle small amounts of clear-water iron
  • Warranty covered (only optional?)

Why NOT to Buy Culligan

In our opinion, there are many reasons why NOT to invest in a Culligan water softener…

Bad Customer Feedback

To Be Fair

Online reviews should always be taken with a grain of salt. Naturally, only those customers that are most passionate about their opinion will share their thoughts. And in this case, these are mostly very unhappy customers. At the same time, such a large percentage of negative feedback is hard to come by – even in the world wide web. Only about 10 percent of the ratings are positive.

The amount of negative customer feedback that Culligan has received over the years and the low overall satisfaction rating are the biggest reasons why we would not opt for a softener sold by this franchise.

First of all, Culligan’s overall rating on is a startling 1.5 stars at the time of writing this article. This is based on 142 reviews. The vast majority of them are 1-star ratings. Then there are a handful of 2 and 3-star ratings, none with 4 stars, and less than 10 reviewers rated the company with 5 stars.

Culligan Water Rating on Consumer Affairs November 18th

Most customers are very disappointed with the products & services that Culligan provides and will not purchase from them in future and do not recommend anyone to do so either.

Pricing Structure

Culligan refuses to provide any prices for their softening systems upfront. What we mean by this is that a local Culligan water expert always has to visit your place first to assess your individual water situation and then you will be given a cost estimate.

This is why on the Culligan website it says: “Because your specific water goals will depend largely on your home’s water, actual pricing can vary. And it’s really hard to say what solution will suit your water best without starting with an in-home evaluation from your local Culligan Man.

Interestingly enough, most other softener companies and brands that we have reviewed up to this point do not follow the same policy. Instead, they will simply provide you with a fixed price on a per model basis.

Exorbitant Cost

Having said that, we’ve digested some pricing information from the ConsumerAffairs reviews:

  • A customer from Ohio pays $115 per month for a rental softener system and bimonthly salt delivery. Considering that a regular softener costs anywhere between $400 and $1,000 on Amazon, it would have paid itself off after less than 1 year.
  • Another family signed a 3-year contract with Culligan to rent their basic softener and RO filtration system including service, which does not cover filters, salt and salt delivery, says the author. Total costs: $5,770.
  • One lady got a quote for a water softener, reverse osmosis system and a sulfur clear system for approximately $8,500. Without knowing more about the circumstances, this seems incredibly expensive.
  • Another person paid $3,000 for a Culligan softener (probably including installation) with a smart sensor.

As you can see, extremely high purchase prices and installation cost are another reason why you are better off with a softener from one of the competitors.

Costly Maintenance & Repairs

And it doesn’t end there. We read many reports about costly maintenance works and repairs, such as $350 for a flow meter replacement (including the meter itself), more than $500 for changing a resin bed, and expensive fees charged for “free” inspections among other things.

We don’t want to just repeat everything that’s already been said on ConsumerAffairs, so definitely go over to the site and read through some of the negative but also positive feedback – and then come back here!

Poor Customer Service

Culligan’s customer service also leaves a lot to be desired. According to reviewers, some company representatives refused to resolve issues with malfunctioning systems that they had caused themselves. Others wanted to charge for work that they never performed.

We also read comments from customers that tried to get in touch with the company or one of its divisions, but never heard back. Or they were put on hold on the phone for so long that they gave up – stuff like that. You get the idea…

Systems Not User Friendly?

Okay, so we are not 100 percent sure about this one. What we do know is that Culligan prefers to install their softeners themselves, obviously to earn more money this way. This does not mean, however, that you could not service or repair a Culligan softener yourself. At least replacement parts are available online.

In a Nutshell

The Fleck 5600 SXT is our most favorite. It’s also among the best selling water softeners on Amazon and comes at a relatively affordable price. 48,000 grains and a service flow rate of 12 gallons per minute provide you with enough water, even if you are a larger family of up to 6 people. The metered system regenerates as needed, which will save you money.

Other than that, the Fleck 5600 SXT can handle clear-water iron of up to 2 parts per million, is easy to DIY-install and even easier to set up. Lots of happy customer and 5 stars from us!

Fleck 5600 SXT

Genesis offers salt-based water softeners in the higher price segment. The Genesis Premier, for example, is available with 5 different resin tank sizes (24,000 to 96,000 grains) and uses metered upflow regeneration for maximum salt and water efficiency.

The systems also comes with high-durability resin which is more resistant to chlorine and chloramines making it a great choice for municipal water supplies. NSF certified – check. Ready for DIY install and quick setup – check. 4 stars.

Genesis Premier

A real alternative to salt-based water softeners are saltless conditioners, such as the Eddy Electronic Water Descaler. Instead of sodium, the descaler uses electromagnetic waves to reduce the scaling effects of hardness minerals.

Nothing will be added or removed from your water. So while you won’t see a drop in TDS, all healthy minerals will be retained. No salt use is also the most environmentally-friendly “softening” solution. Plus not having to buy salt bags saves you time and money.

What’s more, no wastewater will go down the drain and the descaler is available at a fraction of the cost of what you have to pay for a traditional salt-based system. The only downside: As with most conditioners, the Eddy Electronic does not work for all users. Some reported that it did nothing for them in terms of hardness reduction.
