The water supplied to our homes to drink contains an unlimited amount of calcium and magnesium, a type of water referred to as hard water. This water can clog your pipes and make it difficult to dissolve soap and detergents in the water. Water softening is a technique in which calcium and magnesium ions are removed with sodium ions to soften the water.

Things to consider for the best portable water softener:


Apart from making water more portable, this portable water softener increases the lifespan of plumbing and fixturing, saving you money. The following are some things to keep in mind before buying the portable water softener:

Size of the system

There are two ways to look for the perfect size according to your need:

Firstly, you can check its physical size and grain capacity. While buying a portable water softener, physical size isn’t that important, but you should buy it according to your family size.

Secondly, size also includes the weight and space it consumes, so yes, you do have to buy a water softener that is easy to portable. You can also check this by comparing different brands to buy the right one.

Grain capacity of the portable water softener

Many portable water softeners are rated according to their grain capacity. Grain capacity is the maximum grains of hardness that can be removed by a softer before regeneration. It depends on the hardness of the water and the number of people who the single portable water softener will serve. The Harder the water and the higher the number of people using a single water softener, the higher its grain capacity.

Its regeneration cycles and controls

Water softened work by replacing sodium ions with the hard water minerals while the resin bed processes work. When the hard water passes through the resin beads, the hard water minerals get attached to all the sodium ions, and the water becomes soft. After a few months, these resin beads started to get completely covered with the hard water minerals, and the softer water became unable to remove hard water. And that’s the time when your portable water softener requires a cleanup. This process is called regeneration. If you have high grain capacity water softened, you don’t need any regeneration process after a few months as it can easily work for years. But yes, this also depends on the water usage.

Price of the portable water softener

There are various prices for different water softeners as their price depends on the size and flow rate. Checking the price before buying any portable water softener is important. This will tell you how much you have to spend but yes also remember to buy the water softener you only have to pay once not again and again. Sometimes we think that the one with a low price will be okay as the water softener with a low price has low-quality complements that you have to change repeatedly. So always pay for once.

Testing the water hardness:

Before buying the softer water, you should always test your water hardness first. You just have to follow the instructions given on the test strips with the units. This will help you determine the hardness so you can easily buy the right softener. Apart from that, sometimes the water you are going to use needs a softened and a filter. So you can also buy two in one filter and softener to fulfill both of your needs.


Before buying the best portable water softener, many different questions come to our minds. To solve all your queries about the portable water softener, we have listed some commonly asked questions. Their answer is given by the professionals and people using these filters.

2nd: Slow rinse the unit with 1/4th cup of bleach for the standard unit.

3rd: Perform complete regeneration.

How do you flush a portable water softener?

Make a solution by mixing a few tablespoons of dish soap into 1-2 gallons of water, putting this mixture in the brine tank, and using a long handle brush to scrub. Dump and rinse when you are done.

Can you put a water softener in an RV?

How do you charge a portable water softener?
