The Ultimate Guide to Salt Free Water Softeners: Compare and Buy the Best

From a lot of options available on the market, choosing the right salt less water softener can be challenging. To help you buy the best water softeners without salt, I’ve prepared this buying guide.

When you’re planning to shop for a non-salt water softener, you need to consider some factors. It’ll help you to know which model is right for you.

Technology Matters

Nonsalt water softener systems use several methods to neutralize the compounds in water that make it hard. The technology used in water softener has a serious implication on the efficiency and performance of the unit. The output of a device heavily depends on the technology applied.

In general, there are four types of technologies that salt free water softeners use. In some technology, the microbes, chlorine and harmful particles are flushed out, whereas others dissolve any scale that may be embedded into the plumbing system.

Size and Flow Rate

When buying any water softener, selecting the right size is essential. You’ll get one that can handle the demands of your household. However, it doesn’t mean the physical dimension; instead it’s the ability to remove “hardness” from water. Water softeners come with different flow rate and size.

Depending on the number of your family members and the hardness of your household water, you need to choose the water softener with the right flow rate and size. Remember, the low flow rate means less water pressure if you need to use water at one more point in your home.

Ease of installation

Opt for easy to install and maintain a softener system. Compact and simple designs not only allow straight forward installation. Find out whether it offers DIY installation or you’ll need a plumber or special factory service person.

Pay attention to the maintenance required for the unit. If you have the DIY experience, it’ll also save you a technician or professional installation costs.


You won’t be likely to buy a water softener each year. So, select a unit which is made of high-quality component and serve you for many years. Even if you need to spend a little more to buy a high-quality unit, it’ll be cost-effective in the long run.

Brand and Warranty

Find the best water softener brand. Consider the level of service, and, of course, warranty. It’s wise to choose a renowned brand. That way, you’ll get a quality water softener backed by an established brand.


Don’t forget to look for the water softener certification. Remember that these certifications guarantee the unit’s performance, but it ensures that the device has successfully passed tests for industry standards. What’s more, it’ll ensure you long term trouble-free service.
