The 12 Best Water Softeners of 2022

It may surprise you that around 85% of all households in the USA are supplied with hard water. That means unless you know for sure that you don’t have water hard water running through your pipes, you probably do. Is this a big problem? Well, it depends on your definition of “big.” Hard water is certainly not going to kill you. But if you want clean, tasty drinking water straight from the faucet, prevent your shower head from clogging up and prolong the life of your hot-water appliances, it may be time to invest in one of the best water softeners.


What Is a Water Softener?

A water softener is a device capable of removing the minerals present in hard water, which causes it to be hard. Usually, these minerals are calcium and magnesium. When not treated, hard water running through your home can cause several minor inconveniences and some serious ones.

Problems caused by hard water include:

  • Bad Taste: To be clear, drinking hard water is not a problem. And it may even be better for you to do so, thanks to the calcium and magnesium it contains. However, the big problem for most people is the unpleasant taste.
  • Hair/Skin Problems: If you are bathing in hard water, you will find the calcium and magnesium in hard water create a thin film on your hair and skin. For hair especially, this film prevents moisture from passing through, resulting in hair far more prone to breaking.
  • Stains/Slime/Spots: Washing up with hard water tends to leave noticeable marks on your glasses, dishes, and other kitchenware. It also feels different against your skin, with a slimier, more unpleasant feel.
  • Problematic Buildups: Over time, having hard water running through your home produces build-ups in your pipes, faucets, shower heads, and perhaps most importantly, your hot-water appliances. Left unchecked, these buildups create blockages and inhibit your device’s ability to work efficiently. And when we’re talking about expensive devices like your washing machine, water heater and dishwasher, it becomes clear why hard water is best avoided.

This is why the best answer to hard water is to install one of the best water softeners.

How Do Water Softeners Work?

Most commonly, a house water softener uses a chemical process called ion exchange to remove calcium and magnesium from hard water. However, if you want to avoid using salt, salt-free water softeners can use electricity or filters to reduce or manage the hard water running through your pipes.

In terms of salt-based water softeners, these devices feature an ion-exchange resin that is negatively charged to make it attractive to positively charged ions. Before the process begins, this resin is bound to positively charged sodium and potassium ions. Then, once hard water is passed through this resin, the sodium and potassium ions are removed and replaced by calcium and magnesium due to their more substantial positive charge. This leaves you with a water softener filled with resin bound to unwanted calcium and magnesium ions removed from the water.

Eventually, the resin becomes saturated with calcium and magnesium ions. At this point, your water softener undergoes a process called regeneration. This requires a certain amount of water and, more importantly, salt. This is why salt must always be available for a water softener to function correctly. Once the regeneration cycle is complete, the softening process starts over again.


Salt-Free Water Softeners

In addition to devices requiring salt, several softeners and filtration systems don’t use salt to soften water. Instead of salt, most of these salt-free water softeners use electricity. They work by changing the potentially hazardous minerals inside the water and making them less “sticky.” This reduction in stickiness means the minerals don’t attach themselves to kitchenware, clothing, electronics and the inside of pipes, preventing many of the adverse effects mentioned above (although not taste). And if you don’t object to the flavor, this drinking water can be better for your body as it remains full of minerals.

Here is our selection of the 12 best water softener systems. We’ve included a range of styles, from whole-home and portable devices to compact and salt-free water softeners. Scroll down to find the right one for your household needs.
