In some regions, this number can go as high as 180 mg. 

Defeating the hardness of water is not such a tough task, but the rewards of it are great. 

You will be needing only one device and all those problems with spotty laundry, ashy skin, and stained dishes will be gone. 

Once you get your hands on the best water softener filter cartridge on the market (provided in the list below), you will surely have an easier time consuming your municipal water.

Built Fleck 5600sxt
Our list opens up with a budget-friendly option, high quality, whole house water softener systems, this might be exactly the product for your house.

Controlled by the popular Fleck 5600sxt digital valve meter as mentioned on the product page on amazon.

It’s popular for its lower annual power consumption and easy usage, which makes this product worth buying.

With a 48000 grain capacity, the system is designed to remove the majority of “hard water” culprits.

You might need to add a whole house water filter inline and before this softener, if you are concerned about other trace minerals such as iron, etc.

This water softener filter cartridge comes with two preloaded American made tanks with 10 years warranty each and many add-ons.

A considerably added value is its supporting resources provided along with this – installation videos and a kit plus a simplified installation guide.

This is not a water filter so keep in mind that it will not get rid of chlorine and its smell in your water. 

Its main goal is to soften your water and this means that calcium and magnesium sulfate will be removed from the water.

A misconception is that it removes iron which hardens your water, this product doesn’t remove iron.

Don’t be surprised if the water is a little bit cloudy just after installing it.

This might continue over a few minutes or even hours.

The resin needs some time to do its magic for you on water.

And let’s not underestimate the level of the company’s customer support, which is quite well.

Pros & Benefits:

  • The Fleck technology
  • The rich install kit
  • Features a bypass valve
  • Significantly softens water
  • Great customer care
  • Almost 10% more cross-link resin


2. Poly Triple Action Water Softener

Action Water Softener
This softener has deserved the right to line up along with other high-quality products of the same niche.

It is compact in size, practical, and with a reliable and durable body, which makes it worth buying.

On its product page, the company mentioned that it’s completely salt-free, which is a good point for this.

We aren’t going to consider any grain here and this is the main difference from all other products in this class.

It can be installed anywhere, either outside or inside because waterproofing isn’t an issue but the freezing is, so keep a note for that.

The hard water is softened by the very special chemical combination between polyphosphate and the screen filter.

This means that magnesium and calcium carbonates will be completely removed from the water while molecular calcium will remain intact. 

Again this can’t remove iron and chlorine from the water, which is not its function.

Its salt-free technology, however, is better than limescale.

You will notice a significant change in the softness of your hard water.

You can expect very decent working and long-lasting work without a lot of issues here in this unit.

This is important, and it is backed by the manufacturer’s warranties/guarantees. 

You will get a 6 months satisfaction guarantee which means you are getting a full refund if you return the product during the period, additionally, all parts have 5 years of warranty from the company.

When it comes to its handling and installation, again the product behaves well.

Pros & Benefits:

  • BPA-free plastic body
  • 6-month guarantee and a 5-year warranty on all parts
  • Media is completely replaceable
  • Removes calcium carbonate
  • Features salt-free softening technology
  • Can be installed anywhere as long as it doesn’t freeze

ISpring ED2000 solves most of the hard water problems without the need for chemicals, salt, or maintenance.

It keeps all healthy minerals in the water by preventing scale deposits from forming and allowing the existing scale to break down.

It’s not the cheapest nor the most expensive on this list, but it’s quite an interesting unit.

This water softener filter cartridge uses a microcontroller chip that sends electromagnetic waves through the pipes and thus reduces the chances for mineral and limescale build-up in the pipes and tanks.
