What is a Portable Water Softener?

Portable softeners are compact water treatment systems for mobile homes that reduce the water’s hardness.

The unit uses 50-100 gallons (200-400 liters) of circulated water per regeneration.

Their design is based on a conventional water softener but uses a self-contained reservoir filled with brine solution for desalinization.

The softener uses a timer to control the regeneration cycle, which flushes out concentrated brine and restores softness.

They are perfect for mobile homes, RVs, or temporary relocation situations.

The unit will soften water up to 50 gallons a day, depending on the degree of hardness and amount of water.

Types of Portable Water Softeners

Ion Exchange water softener

Ion exchange or salt-based water softener removes calcium and magnesium ions from hard water through an ion-exchange process.

The water softener exchanges the calcium and magnesium (Mg) ions in hard water for sodium (Na) ions through an ion-exchange resin bed.

Then, the hard minerals attach to the resin through ionic attraction, and the sodium ions are exchanged for these minerals by displacement.

The water then passes through a selective membrane that blocks sodium while allowing calcium and magnesium to continue with the water flow.

It provides softened water for about 18 to 24 cents per 1000 gallons.

Salt-free water softener:

The Salt-free water softener is a device to soften water without salt.

It does so by adding calcium and magnesium ions to the water through an ion-exchange process at point-of-use.

The calcium and magnesium ions in hard water precipitate as scale, leaving soft water behind.

Note: This device only functions properly if the feedwater is already “hard,” generally meaning it contains at least 100 ppm (mg/L) of calcium and magnesium ions.

The Salt-free Water Softener consists of a cation exchange resin bed in which calcium and magnesium ions in the water exchange for sodium mineral ions (table salt).

The calcium and magnesium in the softened water precipitate out as scale, leaving soft water behind.

Magnetic Descalers softener:

The magnetic water softener promises to solve your hard water problems without adding chemicals, salt, or potassium.

The makers claim that the inside of the Magnetic Descaler contains hundreds of thousands of tiny magnetic particles.

It works to clean the hard water, which then flows through your home appliances and plumbing fixtures.

The Magnetic Descaler claims to soften your water by replacing the large calcium particles with tiny magnetic particles that your appliances do not detect.

According to the article, a few “hundred dollars” worth of use will last up to 7 years.

Reverse Osmosis system

Reverse osmosis is a technique used to purify water by increasing its purity.

It uses pressure to force pure water through a semi-permeable material that retains impurities.

The RO can remove contaminants from water when ordinary distillation, deionization, and activated carbon filtration are not feasible.

It has a few different water treatment stages, depending on the intended use of the produced water.

A Reverse Osmosis system is a good purification method because it can remove up to 99% of certain contaminants from water.

It includes most mineral ions and molecules, as well as larger particles.

What to Look for When Buying Water Softener for Mobile Home?

Water hardness level

Before you buy a water softener for a mobile home, you need to know the water hardness level.

Hard minerals level is either high or low and affects the water used.

Highly hard water needs to be softened, while low water hardness has no effects.

Before selecting the water softening system type and size, you must know the hardness level.


Before buying a water softener for a mobile home, you need to know what type of system would match your needs.

The type of system depends on the hardness level of water, size of the home, and general needs.

Types include Salt-free and salt-based systems manual and automatic regenerated systems.

You need to know how much water your family uses, the hardness level of water used in the home, and general needs.


The water softener’s size depends on your water usage and its hardness level.

The size of the home determines how much water is used in a day and, therefore, how many gallons of water is used.

To select the best size for your home, make sure to collect all details about the size of your home, its average water usage per day or month, and the hardness level of water.

Grain Capacity

Grain capacity is defined as “the amount of water that it can soften.”

The best grain capacity for a softener depends on the hardness level of water.

If the water hardness is high, buy a system with higher grain capacity and vice versa.

Before buying a water softener for your RV and mobile home, it is essential to know the grain capacity of your softener.

Built-in features

Some water Softeners for mobile homes come with built-in features such as:

Salt level indicator: This shows you when to refill salt in a water softener.

Softener Bypass valve: This allows water flow even when the system regenerates. Manufacturers use a separate bypass valve for additional safety.

Drain cleaning filter: Keeps your drain clean and prevents clogging.

Maintenance port: Helps you to maintain the system easily.

All these features are very useful, but you need to check your system specifications before buying.

Flow rate

Flow rate is defined as the amount of water your system can deliver in a minute.

When you buy a water Softener for a mobile home, you need to check your softener’s flow rate.

If you have high water usage, you will need a system with a higher flow rate and vice versa.

Please select the best product from our list of the best water softeners for a mobile home as per your budget and size.

Installation & Maintenance

If you are planning to get a perfect water Softener for a mobile home, you need to find out if the system is easy to install or not.

If it is easy to install, you will have an easier time maintaining it.

You also need to know about the system’s maintenance needs so that you can choose between salt-based or salt-free systems.

Salt-based water softeners need more maintenance than salt-free systems. Salt is the main ingredient of salt-based softeners.

If you are not comfortable with the maintenance, go for a salt-free system.

What size water softener should I get for my mobile home?

To decide which size of the softener you need, you should find out how much your household uses.

And then, you can choose from various capacities to find the one that matches your water use.

To determine how much water you typically consume, take a look at your past months’ water bills.

Many mobile home water softener brands range from about 1,300 to 8,000 grains. It is a good choice for a family of three to five people.

If you have a family of four, a 5,000-grain capacity is a standard size that can be used efficiently if the water is not too hard.

In this case, a 7,000-grain water softener is the best option for you.

If you have a family of five or more people, you should consider getting a 10,000-grains softener.

Like the 7,000-grain capacity, this type also has very good performance and is considered the best.

Where to install a water softener in a mobile home?

When you have a mobile home or RV, it can be difficult to find space for a softener.

To avoid the hassle of finding the right place to put your unit, you might be interested in buying a portable RV water softener.

If you wonder where to install a water softener system in a mobile home, here is a quick rundown of some available options.

No matter what type of softener you have, if it is a traditional style, you will need to choose between in-line under-the-counter for water softener installation.

For in-line, you would place the unit directly after your meter. That means you should install at least a ¾ inch drain line to the unit.

It should also be between 5-10 feet away from your main water line.

You can also install your unit under the counter, making it a point of use machine, as long as you have about 3 inches of vertical space at the point where you plan to install your unit.

A traditional water softener installation will require a bit of work and a little bit of money.

If you’re not up to the task, consider buying a portable RV water softener.


It is most important to get the perfect water softener for a mobile home or RVs. It will make your life easier.

When deciding which one to buy, consider the amount of water your household generally uses, the cost of softener you are willing to spend on, and the ease of installation.

And once you have made up your mind on the type of water softener for your mobile home, it is time to go looking for a good deal.
